When antibiotics encounter microplastics in aquatic environments: Interaction, combined toxicity, and risk assessments.

Antibiotics and microplastics (MPs), known as emerging pollutants, are bound to coexist in aquatic environments due to their widespread distribution and prolonged persistence. To date, few systematic summaries are available for the interaction between MPs and antibiotics in aquatic ecosystems, and a comprehensive reanalysis of their combined toxicity is also needed. Based on the collected published data, we have analyzed the source and distribution of MPs and antibiotics in global aquatic environments, finding their coexistence occurs in a lot of study sites. Accordingly, the presence of MPs can directly alter the environmental behavior of antibiotics. The main influencing factors of interaction between antibiotics and MPs have been summarized in terms of the characteristics of MPs and antibiotics, as well as the environmental factors. Then, we have conducted a meta-analysis to evaluate the combined toxicity of antibiotics and MPs on aquatic organisms and the related toxicity indicators, suggesting a significant adverse effect on algae, and inapparent on fish and daphnia. Finally, the environmental risk assessments for antibiotics and MPs were discussed, but unfortunately the standardized methodology for the risk assessment of MPs is still challenging, let alone assessment for their combined toxicity. This review provides insights into the interactions and environment risks of antibiotics and MPs in the aquatic environment, and suggests perspectives for future research.

Degradation and humification of steroidal estrogens in the soil environment: A review.

Emerging pollutants are toxic and harmful chemical substances characterized by environmental persistence, bioaccumulation and biotoxicity, which can harm the ecological environment and even threaten human health. There are four categories of emerging pollutants that are causing widespread concern, namely, persistent organic pollutants, endocrine disruptors, antibiotics, and microplastics. The distribution of emerging pollutants has spatial and temporal heterogeneity, which is influenced by factors such as geographical location, climatic conditions, population density, emission amount, etc. Steroidal estrogens (SEs) discussed in this paper belong to the category of endocrine disruptors. There are generally three types of fate for SEs in the soil environment: sorption, degradation and humification. Humification is a promising pathway for the removal of SEs, especially for those that are difficult to degrade. Through humification, these difficult-to-degrade SEs can be effectively transferred or fixed, thus reducing their impact on the environment and organisms. Contrary to the well-studied process of sorption and degradation, the role and promise of the humification process for the removal of SEs has been underestimated. Based on the existing research, this paper reviews the sources, classification, properties, hazards and environmental behaviors of SEs in soil, and focuses on the degradation and humification processes of SEs and the environmental factors affecting their processes, such as temperature, pH, etc. It aims to provide references for the follow-up research of SEs, and advocates further research on the humification of organic pollutants in future studies.

Sluggish and Ion-Resilient Behavior of Interfacial Aqueous Layer on Single-Layer Graphene Oxide: Insights from In Situ Atomic Force Microscopy.

Understanding interfacial interactions of graphene oxide (GO) is important to evaluate its colloidal behavior and environmental fate. Single-layer GO is the fundamental unit of GO colloids, and its interfacial aqueous layers critically dictate these interfacial interactions. However, conventional techniques like X-ray diffraction are limited to multilayer systems and are inapplicable to single-layer GO. Therefore, our study employed atomic force microscopy to precisely observe the in situ dynamic behaviors of interfacial aqueous layers on single-layer GO. The interfacial aqueous layer height was detected at the subnanometer level. In real-time monitoring, the single-layer height increased from 1.17 to 1.70 nm within 3 h immersion. This sluggish process is different from the rapid equilibration of multilayer GO in previous studies, underscoring a gradual transition in hydration kinetics. Ion strength exhibited negligible influence on the single-layer height, suggesting a resilient response of the interfacial aqueous layer to ion-related perturbations due to intricate ion interactions and electrical double-layer compression. Humic acid led to a substantial increase in the interfacial aqueous layers, improving the colloidal stability of GO and augmenting its potential for migration. These findings hold considerable significance regarding the environmental behaviors of the GO interfacial aqueous layer in ion- and organic-rich water and soil.

Participatory intention and behavior towards riparian peri-urban forests management; an extended theory of planned behavior application.

Introduction: Peri-urban forests play crucial role in quality of life and environment for citizens. To effectively utilize the services provided by these forests, it is essential to establish an integrated forest management system that aims to achieve a balance of all ecosystem services. This can be accomplished through a participatory approach that involves key citizen stakeholders. Mountaineers shape a specific group which have showed high pro-environmental behaviors to protect natural resources. This research aimed to examine the influencing factors on mountaineers' intention to participate and their actual behavior in the management of riparian peri-urban forests in this field using extended theory of planned behavior. Methods: Environmental values and perceived barriers were added to original model as additional components to enhance its explanatory power. A sample size of 416 individuals was surveyed using a questionnaire. Data was analyzed using Smart-PLS. Results: The findings of the analysis revealed that the developed model accounted for 75.2% of the variance in mountaineers' intention and 67.8% of behavior. The results demonstrated that three main components of model including attitudes, subjective norms and perceived behavioral control significantly influenced individuals' intentions to participate in peri-urban forests management. Furthermore, intentions were cleared to have a positive influence on actual behavior in this context. Additionally, environmental values were found to be positively correlated with individuals' intentions but not statistically significant behavior toward participate in urban forest management. Perceived barriers were found to have a negative impact on individuals' intentions toward participate in urban forest management. The perceived barriers and behavior had not statistically significant relationship. Conclusion: The results of study provide valuable insights for the development of effective management strategies to promote mountaineers' participation in riparian PUFs management. The study emphasizes the importance of environmental education and awareness campaigns targeted at mountaineers.

Bee Well: a positive psychological impact of a pro-environmental intervention on beekeepers' and their families' wellbeing.

Bees are excellent pollinators and serve an essential environmental purpose. However, little is known about the wellbeing impact of bees on humans. This research addressed the knowledge gap concerning the impact of beekeeping on the wellbeing of beekeepers and their families, focusing on the often-overlooked psychological, emotional, and social dimensions. Thirty farmers in Ireland participating in the Let it Bee project, aimed at promoting biodiversity and water source protection, were provided with bee hives. Twelve participants were interviewed to explore the effects of beekeeping on their wellbeing. Thematic Analysis was employed to analyze the data, revealing five central themes. (1) The centrality of pride in accomplishing environmental and community objectives in the farmers' beekeeping activities; (2) the evolving sense of togetherness with nature, family, and community throughout the project; (3) a profound sense of contributing significantly to the greater good; (4) the recognized value of beekeeping for beekeepers' psychological growth, flow, and relaxation; and (5) the opportunity for beekeepers to leverage their character strengths. The implications of these findings are discussed within the framework of their impact on environmental conservation, healthcare policymaking, and implications for research and practice.

3 Months without the car in Bielefeld, Germany- a mixed-method study exploring individual motivation to participate in a municipal intervention.

BACKGROUND: Climate change is a major public health issue worldwide. To achieve climate targets and reduce morbidity, a paradigm shift in individual behavior e.g., in mobility, is needed. Municipal interventions can motivate individuals to engage in climate-friendly behavior through different psychological mechanisms. In order for successful interventions, it is necessary to gain better insight from study participants and their reasons for participating in mobility projects (e.g., motivational aspects). MATERIALS AND METHODS: A mixed-methods design was used to evaluate reasons and characteristics of people for participating in an municipal mobility intervention. The quantitative sub-study assesses socioeconomic characteristics, environmental awareness and perceived stress. The qualitative sub-study explores motivation for participation and change, perspectives on car replacement and reasons for car use. RESULTS: Results show that participants (n = 42) are rather high educated and show medium environmental awareness. Participants of the qualitative study part (n = 15) were motiviated to reduce car use already before the intervention and used the intervention as starting point or trial phase. CONCLUSIONS: Urban intervention projects with fitted recruitment strategies and better insights from study participants with the aim to motivate individuals to engage in climate-friendly behavior can help to strengthen sustainability and public health.

Refocusing on nature: the role of nature reintegration in environmental, mental, and societal wellbeing.

This perspective paper investigates the dynamic interplay between wealth, materialism, environmental degradation, and mental health amid escalating challenges of climate change. The paper critically examines how affluence, often a buffer against climate impacts, paradoxically leads to higher consumption and carbon footprints, exacerbating environmental problems. A societal emphasis on materialism contributes to an estrangement from nature, with significant implications for mental health and environmental sustainability. The paper proposes a fundamental shift in addressing these intertwined challenges through reintegration with nature. The paper recommends integrating urban planning, education, mental health, and community engagement strategies to build a sustainable, mentally resilient society more integrated with nature. This approach, supported by future research directions, aims to create a more balanced, environmentally conscious, and mentally healthy world.

Microplastics derived from plastic mulch films and their carrier function effect on the environmental risk of pesticides.

Plastic film mulching can maintain soil water and heat conditions, promote plant growth and thus generate considerable economic benefits in agriculture. However, as they age, these plastics degrade and form microplastics (MPs). Additionally, pesticides are widely utilized to control organisms that harm plants, and they can ultimately enter and remain in the environment after use. Pesticides can also be sorbed by MPs, and the sorption kinetics and isotherms explain the three stages of pesticide sorption: rapid sorption, slow sorption and sorption equilibrium. In this process, hydrophobic and partition interactions, electrostatic interactions and valence bond interactions are the main sorption mechanisms. Additionally, small MPs, biodegradable MPs and aged conventional MPs often exhibit stronger pesticide sorption capacity. As environmental conditions change, especially in simulated biological media, pesticides can desorb from MPs. The utilization of pesticides by environmental microorganisms is the main factor controlling the degradation rate of pesticides in the presence of MPs. Pesticide sorption by MPs and size effects of MPs on pesticides are related to the internal exposure level of biological pesticides and changes in pesticide toxicity in the presence of MPs. Most studies have suggested that MPs exacerbate the toxicological effects of pesticides on sentinel species. Hence, the environmental risks of pesticides are altered by MPs and the carrier function of MPs. Based on this, research on the affinity between MPs and various pesticides should be systematically conducted. During agricultural production, pesticides should be cautiously selected and used plastic film to ensure human health and ecological security.

Exploring fishers' pro-environmental behavioral intention and support for policies to combat marine litter in Vietnam.

This study applies Value-Belief-Norm (VBN) theory to investigate fishers' pro-environmental behavioral intention and their support for policies to reduce marine litter. While pro-environmental behavioral intention is often associated with personal environmental intention at the household level, policy support represents their support for government action at the political level. Therefore, we examine whether fishers are willing to engage in both of these dimensions. Data from 369 Vietnamese fishers are analyzed using structural equation modeling with FIMIX-PLS and PLS-POS. The results show that the sequence of values, beliefs, and personal norms can explain the fishers' pro-environmental behavioral intention and their support for policies addressing marine litter. Two segments of the fishers are detected from the sample with different perspectives of engagement intention. Fishers in segment 1 placed great emphasis on the consequences of marine litter on fishing activities as a motivator for their responsible actions. Meanwhile, fishers in segment 2 express pro-environmental engagement intention driven by the concern about responsibility and moral obligation. A binary logistic regression indicates that the risks of marine litter on fishing activity can provide the explanations for the differences between them. Our findings highlight both fishers' pro-environmental behavior and policy support as important strategies for dealing with marine litter in fisheries. If implemented simultaneously, they hold promise to alleviate the environmental and economic impact of marine litter in Vietnam.

Heavy metal migration dynamics and solid-liquid distribution strategy in abandoned tailing soils.

The tailings soil originating from an abandoned sulfur-iron mine in Sichuan Province, China, exhibits elevated concentrations of heavy metals (HMs) and possesses limited soil conservation capacity. Variability soil particle size fractions (PSFs) contributes to an increased risk of HMs ion migration. Existing research on HMs behavior has focused on the bulk soil scale, resulting in a dearth of comprehensive information concerning different particle sizes and colloid scales. We collected soil samples from upstream source (XWA), migration path (XWB), and downstream farmland (XWC) of an abandoned tailing and categorized into sand, silt, clay, colloid and dissolved, respectively. The investigation primarily aimed to elucidate the solid-liquid distribution trade-off strategies of soil HMs along migration pathway. Results show that PSFs composition predominantly influences HMs solid-liquid distribution. In the mining area, large particles serve as the principal component for HMs enrichment. However, along the migration pathway, the proportion of highly mobile fine particles increases, shifting HMs from solid to liquid phase. Furthermore, inorganic elements such as Mg, Al, and Fe influence on HMs distribution within PSFs through various reactions, whereas organic matter and glomalin-related soil protein (GRSP) also exert regulatory roles. Increasing the proportion of large particles can reduce the risk of HMs migration.

Place attachment mediates links between pro-environmental attitudes and behaviors among visitors to Mt. Bukhan National Park, South Korea.

Introduction: Efforts to understand visitors' participation in pro-environmental behaviors (PEB) are important for protected area management. Previous research in nature-based recreation settings suggests environmental attitudes may affect PEB, and that these relationships might be mediated by different dimensions of place attachment (place identity and place dependence). Methods: We used structural equation modeling to test the mediating effect of hikers' place attachment in the relationship between environmental attitudes and PEBs that occur within (on-site) and outside a protected area (off-site): Mt. Bukhan National Park in South Korea. Results: Results showed that cognitive (environmental knowledge) and affective (environmental sensitivity) components of environmental attitudes were significant predictors for place attachment. Place identity was linked to off-site PEB, while place dependence was a key antecedent for both off-site and on-site PEBs. Discussion: Our findings could help researchers and practitioners better understand how place attachment forms and how it can impact outdoor recreationists' behavior, ultimately helping to promote PEBs and facilitate sustainable management goals.

Pro-environmental behavior, personality and emotional intelligence in adolescents: a systematic review.

Introduction: Human behavior significantly contributes to environmental problems, making the study of pro-environmental behavior an important task for psychology. In this context, it is crucial to understand the pro-environmental behavior of adolescents, as young people play a fundamental role in facilitating long-term changes in environmental consciousness and encouraging decision-makers to take action. However, little is currently known about the pro-environmental behavior of adolescents. Recently, there has been growing interest in examining the influence of personality traits and emotional intelligence on pro-environmental behavior. Methods: We conducted a systematic review to enhance our understanding of adolescent pro-environmental behavior. Thus, this systematic review was designed to enhance understanding of adolescent's pro-environmental behavior by summarizing existing evidence on how it relates to personality and emotional intelligence. Results: Our findings suggest associations between specific personality traits and dimensions of emotional intelligence with adolescent pro-environmental behavior, aligning with similar studies conducted on adults. Discussion: While our findings offer valuable insights, further research is needed to establish causality and deepen our understanding of the interplay between multiple variables influencing pro-environmental behavior among adolescents.

A Latest Review on Micro- and Nanoplastics in the Aquatic Environment: The Comparative Impact of Size on Environmental Behavior and Toxic Effect.

Micro and nanoplastics (MNPs) have attracted growing global research attention due to their distinct environmental impacts, addressing escalating concerns. The diverse materials, sizes, and shapes of MNPs result in a range of environmental impacts. Size, a crucial characteristic of MNPs, influences their environmental behavior, affecting processes like migration, sedimentation, aggregation, and adsorption. Moreover, size modulates the biodistribution and toxicity of MNPs in aquatic organisms. This review delves into the comprehensive impacts of plastic size, with a primary focus on environmental behavior and toxic effects. Ultimately, this review emphasizes the ecological implications of MNP size, laying a foundation for future research in this field.

Simulating behavior of perfluorooctane sulfonate (PFOS) in the mainstream of a river system with sluice regulations.

Perfluorooctane sulfonate (PFOS) is a persistent, anionic and ubiquitous contaminant that undergoes long-range transport within the environment. Its behavior has attracted wide-range academic and regulatory attention. In this article, a mass balance model was employed to simulate PFOS concentrations in the mainstream of Haihe River water system, encompassing sluices and artificial rivers. The dynamic simulation of PFOS concentrations in both sediment and freshwater took into account fluctuations in PFOS emissions, water levels and water discharge. Furthermore, the study delved into exploring the impacts of sluices and artificial rivers on the behavior of PFOS. The simulated concentrations of PFOS in steady state agreed with the measured concentrations in surveys carried out in Nov. 2019, July 2020, Oct. 2020, and June 2021. Every year, approximately 24 kg PFOS was discharged into the Bohai Sea with Chaobai New River being the largest contributor for 44 %. Moreover, the transport of PFOS in the original rivers is likely to be restricted by sluices and replaced by artificial rivers. Monte Carlo analysis showed that model predictions of PFOS concentrations in sediment were subject to greater uncertainty than those in freshwater as the former is impacted by more parameters, such as density of sediment. This study provides a scientific basis for the local government to manage and control PFOS.

Bringing the emerging organophosphate flame retardants (eOPFRs) into view: A hidden ecological and human health threat.

The production and usage of organophosphate flame retardants (OPFRs) in textiles, plastics, and electronics have surged, with phosphorus-based flame retardants constituting over 30 % of the global consumption of flame retardants. Meanwhile, concerns regarding the potential hazards of OPFRs to ecosystems and human health including disruptions in the endocrine system, inhibition of reproduction, and manifestation of developmental defects have intensified. However, our comprehensive data analysis has unveiled a pronounced and critical knowledge gap, as at present, a majority of studies emphasize the attributes of traditional OPFRs, such as triphenyl phosphate (TPHP), while emerging OPFRs (eOPFRs) remain undeservedly overlooked. We elaborated on the current advancements and challenges regarding eOPFRs research and demonstrated that eOPFRs exhibit considerable diversity in terms of their chemical structures, substantial residue levels, broad sources of occurrence, and limited understanding of their potent (eco)toxicological implications. In light of these attributes, it becomes evident that the environmental and health risks of eOPFRs can be comparable to, if not surpass, those attributed to traditional OPFRs. This compelling observation underscores an imperative need for heightened research focus and extensive research efforts dedicated to the study of eOPFRs, rather than still focusing on the realm of their traditional counterparts. Despite the challenges ahead, the emphasized environmental surveillance and toxicological assessment are imperative to prevent the potential evolution of these compounds into a significant ecological and human health threat.

Promoting Pro-Environmental Behavior in Policymaking: A Text-Mining Approach for Literature Review.

The impact of pro-environmental behavior on policymaking has been an exciting area of research. While the relationship between pro-environmental behavior and policymaking has been explored in numerous studies, there needs to be more synthesis on this topic. This is the first text-mining study of pro-environmental effects in which policymaking is a significant factor. In response, this study, for the first time, takes a novel approach by using text mining in R programming to analyze 30 publications from the Scopus database on pro-environmental behavior in policymaking, highlighting major research themes and prospective research areas for future investigation. Results from text mining yielded 10 topic models, which are presented with a synopsis of the published research and a list of the primary authors, as well as a posterior probability via latent Dirichlet allocation (LDA). Additionally, the study conducts a trend analysis of the top 10 journals with the highest impact factor, considering the influence of each journal's mean citation. The study offers an overview of the impacts of pro-environmental behavior in policymaking, showing the most relevant and frequently discussed themes, introduces the scientific visualization of papers published in the Scopus database, and proposes future study directions. These findings can help researchers and environmental specialists better understand how pro-environmental behavior can be fostered more effectively through policymaking.

Pro-environmental practice among young population: A scoping review.

INTRO: There is an inequality between pro-environmental knowledge acquisition and behavior. A change in behavior is required to solve both current and future environmental challenges since human behavior has an influence on pro-environmental practices. OBJECTIVE: Of the study was to carry out a critical analysis of current literature on Pro-environmental practices among the Young population. METHOD: The research question formulation on PICO served as the foundation for the search approach. Keywords were searched in different combinations from the popular databases SCOPUS, PubMed, Medline, Google Scholar, EMBASE, Google and Cochrane library Boolean operators (AND and OR) and keywords were employed in the search to avoid oversaturating the data. Fifteen full-text articles were selected for the study. RESULT: Review studies confirmed that youth engagement is highly valued, with evidence from increasing usage of information and communication technologies (education and environmental consciousness among young people. Analysis of pro-environmental practices and environmental behavior has to be given greater attention considering to the adverse impacts of the existing lifestyle on the environment. This made it possible to incorporate and simultaneously explore a variety of variables and effects on environmental practices, furthering the understanding of how these are interpreted. CONCLUSION: This study pointed up and made contributions to the expanding field of environmental practices barriers. The challenges found should be taken into account in its entirety and utilized to directly inform policies and procedures in order to promote adoption for practices reduction and remove the obstacles inhibiting change.

Does pro-environmental attitude predicts pro-environmental behavior? Comparing sustainability connection in emotional and cognitive environments among football fans and university students.

Environmental sustainability is an imperative topic in contemporary business-related research, aiming to understand and predict how individuals' environmentally friendly behaviors can be encouraged. This research aims to empirically examine the relationship between individuals' pro-environmental attitude and pro-environmental behavior; and to compare two groups of individuals that encompass emotional and cognitive links to environmental sustainability: emotionally involved sport fans and socially conscious university students. Two studies, involving more than 1400 respondents, were conducted. Study 1 uses structural equation modelling (SEM) to test the relationship between consumers' environmental attitudes and environmental behaviors. Study 2 uses SEM multigroup analysis to compare the attitudes and behaviors of sport fans and university students. The results showed that participants' pro-environmental attitude had a positive and significant effect on pro-environmental behavior. The type of consumer plays an important role in strengthening the relationship between pro-environmental attitude and pro-environmental behavior. Despite the higher average levels of pro-environmental attitude and pro-environment behavior evidenced by the sport fans, the influence of attitude on behavior is higher on socially conscious students, the group with a more cognitive and intrinsic link with the natural environment and sustainability initiatives. Despite the positive link attitudes-behaviors, empirical insights suggest that the connection between sport fans and the club is vital to reinforce the commitment with a stronger match between attitudes and behaviors. The findings also have implications for practitioners and policymakers in optimizing their strategies to encourage effective pro-environmental actions.

Pro-Environmental Behavior and Climate Change Anxiety, Perception, Hope, and Despair According to Political Orientation.

The main objective of this paper is to assess pro-environmental behavior, climate change anxiety, perception, hope, and despair in different political orientations. Our specific aims included to assess the validity of all the instruments used; to assess whether the factor structure of the scales were valid across political orientations; to evaluate their reliability; to assess differences concerning age, gender, and political orientation; to learn the variables that explain pro-environmental behavior; and to evaluate the moderating role of climate change perception, despair, and hope in the relationship between climate change anxiety and pro-environmental behavior. Confirmatory factor analyses (CFAs), multi-group CFAs (to calculate measurement invariance), multiple linear regressions, and moderations were performed. Results showed that pro-environmental behavior and climate change hope achieved the four assessed levels of invariance across different political orientations; climate change anxiety achieved the first three levels of invariance; and climate change perception and climate change despair achieved configural invariance. Climate change anxiety, personal experience with climate change, and climate change perception (total, reality, and consequences) presented higher values for the left political orientation than for the right or the center. Climate change anxiety variables contributed most to explaining pro-environmental behaviors. Hope, despair, and climate change perception (consequences) moderated the relationship between climate change anxiety and pro-environmental behavior. These results open up new avenues for investigation, specifically to understand why high levels of anxiety lead to more pro-environmental behaviors.

Long-term control of non-point source pollution by adjusting human environmental behavior in watershed-a new perspective.

The control of non-point source pollution is a major scientific and technological problem faced by mankind. We proposed a new approach to eliminate non-point source pollution, focusing on adjusting human environmental behavior. The implementation procedures are as follows: (1) Investigate the intention of pollution discharge behavior through interviews and questionnaires. (2) Carry out targeted intervention within the framework of social psychology to transform it into an environmentally friendly mode. (3) Calculate the amounts of pollutants produced and discharged before and after the intervention, and then evaluate the effect of the intervention on reducing pollution. (4) Based on successful interventions, a scheme can be developed to curb non-point source pollution. Aiming to reduce fertilizer use, a case study was conducted in Hetao Irrigation District, one of the three major Irrigation districts in China. The results showed that the interventions indirectly affected intention through attitude, subjective norm, and perceived behavioral control. The structural equation model explained 76.0% of the total variance of farmers' intention to reduce fertilizer application (SMC = 0.760), indicating effective intervention. Subsequently, a program to curb non-point source pollution was developed. This study can provide a key scientific and applied reference for the long-term control of non-point source pollution in watershed.
