Exploring the abundance and characteristics of litter in Lithuanian riversides: a citizen science approach.

To gain a better understanding of the sources and ecological effects of plastic contamination in Lithuanian rivers, as well as to provide guidance for mitigation, monitoring is necessary. This is a logistically and financially demanding endeavor, particularly in the case of microplastics. Citizen science provides a viable option for sampling sites that are accessible, thus enabling the monitoring of wide areas. In Lithuania, a citizen science approach was employed, with schoolchildren examining litter at riversides and identifying potential sources at 24 sampling sites in Autumn 2022 and 32 in Spring 2023, covering both large and small rivers. The maximum amount of 220 items per location was registered in Autumn 2022, whereas 111 items per location were registered in Spring 2023. The two main types of microlitter discovered were plastic (34-42%) and cigarette butts (17-22%), with glass, paper, and metal also present, which suggests that recreational visitors are the main source of litter. By K-means clustering analysis, all locations were divided into four clusters according to litter composition. To sum up, the findings of this study illustrate the importance of citizen science in providing insight into the contamination of Lithuanian rivers, which can be used to inform the development of conservation strategies.

Associations between tobacco and cannabis use and anxiety and depression among adults in the United States: Findings from the COVID-19 citizen science study.

BACKGROUND: Little is known about whether people who use both tobacco and cannabis (co-use) are more or less likely to have mental health disorders than single substance users or non-users. We aimed to examine associations between use of tobacco and/or cannabis with anxiety and depression. METHODS: We analyzed data from the COVID-19 Citizen Science Study, a digital cohort study, collected via online surveys during 2020-2022 from a convenience sample of 53,843 US adults (≥ 18 years old) nationwide. Past 30-day use of tobacco and cannabis was self-reported at baseline and categorized into four exclusive patterns: tobacco-only use, cannabis-only use, co-use of both substances, and non-use. Anxiety and depression were repeatedly measured in monthly surveys. To account for multiple assessments of mental health outcomes within a participant, we used Generalized Estimating Equations to examine associations between the patterns of tobacco and cannabis use with each outcome. RESULTS: In the total sample (mean age 51.0 years old, 67.9% female), 4.9% reported tobacco-only use, 6.9% cannabis-only use, 1.6% co-use, and 86.6% non-use. Proportions of reporting anxiety and depression were highest for the co-use group (26.5% and 28.3%, respectively) and lowest for the non-use group (10.6% and 11.2%, respectively). Compared to non-use, the adjusted odds of mental health disorders were highest for co-use (Anxiety: OR = 1.89, 95%CI = 1.64-2.18; Depression: OR = 1.77, 95%CI = 1.46-2.16), followed by cannabis-only use, and tobacco-only use. Compared to tobacco-only use, co-use (OR = 1.35, 95%CI = 1.08-1.69) and cannabis-only use (OR = 1.17, 95%CI = 1.00-1.37) were associated with higher adjusted odds for anxiety, but not for depression. Daily use (vs. non-daily use) of cigarettes, e-cigarettes, and cannabis were associated with higher adjusted odds for anxiety and depression. CONCLUSIONS: Use of tobacco and/or cannabis, particularly co-use of both substances, were associated with poor mental health. Integrating mental health support with tobacco and cannabis cessation may address this co-morbidity.

Using citizen science to understand floating plastic debris distribution and abundance: A case study from the North Cornish coast (United Kingdom).

Citizen science is now commonly employed to collect data on plastic pollution and is recognised as a valuable tool for furthering our understanding of the issue. Few studies, however, use citizen science to gather information on water-borne plastic debris. Here, citizen scientists adopted a globally standardised methodology to sample the sea-surface for small (1-5 mm) floating plastic debris off the Cornish coast (UK). Twenty-eight trawls were conducted along five routes, intersecting two Marine Protected Areas. Of the 509 putative plastic items, fragments were most common (64 %), then line (19 %), foam (7 %), film (6 %), and pellets (4 %). Fourier-transform infrared spectroscopy identified the most common polymer type as polyethylene (31 %), then nylon (12 %), polypropylene (8 %), polyamide (5 %) and polystyrene (3 %). This study provides the first globally comparative baseline of floating plastic debris for the region (mean: 8512 items km-2), whilst contributing to an international dataset aimed at understanding plastic abundance and distribution worldwide.

What potential does the EU Single-Use Plastics Directive have for reducing plastic pollution at coastlines and riversides? An evaluation based on citizen science data.

To address environmental pollution by plastic litter, the European Union adopted EU Directive 2019/904, the so called "Single-Use Plastics Directive" (SUPD), which bans several single-use plastic products and addresses additional items with measures such as extended producer responsibility and obligatory requirements for product redesign. This study assessed the potential of the SUPD to reduce litter pollution in the environment with three scenarios. The "best case" scenario assumed that all measures of the SUPD completely prevent targeted items from getting into the environment. Another scenario assumed that no measures besides bans were effective. An intermediate scenario assumed partial effectiveness of measures. Data of almost 5,000 sampling events from citizen science protocols (Plastic Pirates, International Coastal Cleanup, Marine Litter Watch) and the OSPAR protocol were used to analyse litter at riversides and coastlines in Germany and the European Union. 44 to 68% of litter items in citizen science protocols consisted of single-use plastics (cigarette butts were the most prominent items). At coastlines sampled by the OSPAR protocol, fishing gear and undefined plastics prevailed. The scenario analysis revealed that substantial litter reductions could be achieved in the "best case" scenario (upwards of 40%), while the intermediate scenario resulted in litter reductions of 13 to 25%. The marginal effect of the "only bans" scenario achieved a reduction of 2-6% in Germany and the European Union, respectively. Thus, depending on implementation and enforcement, the current SUPD can be an important first step, yet further legislative actions are needed to effectively prevent plastic waste pollution.

Addressing the challenge of marine plastic litter in the Moroccan Mediterranean: A citizen science project with schoolchildren.

In this study, based on data collected by citizen science, we studied the abundance, spatial and temporal distribution of marine litter in three beaches of the Moroccan Mediterranean. A total of 14,042 litter items were collected with an average abundance of 0.58 items/m2. The most of litter were composed of anthropic polymeric materials, representing 74 % of the total litter collected. Plastics account for the majority of the items collected and are mainly caps/lids, crisp/sweet packets, plastic/polystyrene, cigarette butts and small plastic bags. Litter abundance displayed significant seasonal differences, with the highest during summer. Tourism and poor waste management practices are the major sources of plastic on the beaches surveyed. The use of the Clean Coast Index (CCI) and the Plastics Abundance Index (PAI) permits the classification of the three beaches in the Moroccan Mediterranean as a "moderately clean" coastal area with a "very high abundance" of plastics. In addition, the Hazardous Items Index (HII) allows classification of the region as highly polluted by hazardous litter. Best management measures are needed to promote the environmental quality of the beaches of the Moroccan Mediterranean.

Nationwide Termite Pest Survey Conducted in Taiwan as a Citizen Science Project.

Information regarding the species composition and dispersal flight season of termites is crucial for termite management. The major obstacles to collecting such information are a lack of access to private buildings and shortage of workers to monitor and report on termite swarming. To overcome these difficulties, we launched a citizen science project in which members of the public and pest management professionals were invited to collect termite samples. We created the website, Taiwan Termite Identification Service, on which populace could log the collection information, and ship termite samples to our laboratory for identification. We also established a Facebook group, called the "Termite Forum," to publicize this project. A total of 3024 samples were collected from 2015 to 2020, and we identified the species of >93% of the samples. Based on 1499 samples collected from buildings, five structural termite pests were identified, and species composition in each county of Taiwan is available. According to 844 dispersal flight events, termite dispersal flight timing peak and degree of centralization were estimated using a Gaussian model. The collected data demonstrated that the invasive termite species, Coptotermes gestroi (Wasmann) (Blattodea: Rhinotermitidae), continued northward expansion. The first intercepted alate of Schedorhinotermes sp. (Blattodea: Rhinotermitidae) indicated that it may be a new invasive pest from Southeast Asia. This study reports on a successful case of a citizen science project where urban pest data were collected on a national scale.

Citizen science as a tool for collaborative site-specific oil spill mapping: the case of Brazil.

Many maritime disasters lead to oil pollution, which undermines ecosystem balance, human health, the prosperity of countries and coastal areas across borders, and people's livelihoods. This is a problem that affects the whole world. Governments must strive to ensure that operations in the marine environment are safe and avoid oil pollution by adopting methods that anticipate future scenarios to mitigate the effects of this pollution when it occurs. This study investigates a method of managing contaminated coastal areas, aiming to contribute to the management of the environmental crisis caused by disasters through the use of online collaborative mapping by volunteer collaborators. Volunteer collaborators have been sending georeferenced data and photographs of locations affected by pollution. This information is processed and printed on a cartographic basis created by the web-mapping platform, Google MyMaps©. Photos of 90 locations were plotted on the map, and the pictures demonstrate that the oil slicks that reached the Brazilian coast had very different shapes and consistency. This research can contribute as a participatory monitoring tool during and after oil spills, promoting the oriented preservation of marine ecosystems through citizen science.

GENIGMA: an app to map the 3D genome of cancer cell lines through extreme citizen science.

In this Scientists' Forum article, we present a new app, GENIGMA, launched by structural genomics specialist Marc A. Marti-Renom and his team, aimed at mapping the 3D genome of cancer cell lines. GENIGMA is a digital game, which was designed and tested through a co-creation process with citizens. Finally, by playing the game, citizens produce data, reaching beyond the capacity of artificial intelligence. This is an exceptional experiment of extreme citizen science, which broadens the implications of open science.

Applying citizen science to engage families affected by ovarian cancer in developing genetic service outreach strategies.

Citizen science (CS) approaches involving non-professional researchers (citizens) as research collaborators has been used infrequently in health promotion generally and specifically, in cancer prevention. Standardized CS approaches may be especially useful for developing communication interventions to encourage families to consider cancer genetic services. We engaged survivors of ovarian cancer and their close relatives as CS collaborators to collect and help interpret data to inform content for a website, printed invitation materials, and short-message reminders. We applied an implementation quality framework, and posed four research questions regarding the feasibility of CS: recruitment, data collection, data quality and evaluation of the experience. CS members were recruited through three networks: clinical sites, local and national cancer support organizations, and online ovarian cancer patient support groups. The professional research team operationalized theory-aligned CS tasks, five data collection options, question banks/scripts for creating surveys, structured interviews, online training and ongoing support from research coaches. 14 CS members agreed to the 12-week and 20-hour commitment for an honorarium. CS members opted to do both qualitative and quantitative assessments. CS members collected 261 surveys and 39 structured interviews. The largest number of surveys were collected for Task 1 (n = 102) to assess survivors' reactions to different possible options for motivating survivors to visit a study website; 77% of this data were complete (i.e., no missing values). Data collected for tasks 2, 3, 4, and 5 (e.g., assessment of survivors' and relatives' respective communication preferences) ranged from 10 to 58 surveys (80% to 84% completeness). All data were collected within the specified time frame. CSs reported 17 hours of work on average and regarded the experience positively. Our experience suggests that CS engagement is feasible, can yield comprehensive quantitative and qualitative data, and is achievable in a relatively a short timeline.

Exploring the potential of citizen science for public health through an alcohol advertising case study.

Citizen science connects academic researchers with the public through combined efforts in scientific inquiry. The importance of involving impacted populations in health research is well established. However, how to achieve meaningful participation and the methodological impact of citizen science needs further examination. We examined the feasibility of using citizen science to understand the impact of alcohol advertising on Australian women through a breast cancer prevention project. Two hundred and eighty-two ('participants') citizen scientists completed demographic and behavioural questions via an online survey. The research participants moved into the role of citizen scientists by completing the data collection tasks of capturing and classifying images of alcohol advertising they saw online. Interrater reliability tests found high levels of agreement between citizen scientists and academic researchers with the classification of alcohol advertising brand (Kappa = 0.964, p < 0.001) and image type (Kappa = 0.936, p < 0.000). The citizen scientists were women aged 18 and over, with 62% between 35 and 55 years old. The majority were from major cities (78%), had attained a bachelor's degree or higher-level education (62%) and were recruited via email or Facebook (86%). The use of citizen science provided methodological gains through the creation of a unique dataset with higher levels of validity than the existing literature, which employed traditional investigator-driven research methodologies. Citizen science enriched the dataset and provided a powerful methodological vehicle to understand an environmental determinant of health. The study illuminates how public participation benefitted the research process, the challenges and the potential for citizen science to improve public health.

Nonscalability of "citizen science" in post-Fukushima Japan: Unpacking articulations of citizen radiation measuring organizations.

This article explores and discusses understandings of citizen science with members of Japanese citizen radiation measuring organizations who began measuring radioactive contamination in food, soil, air, and human bodies after the 2011 Fukushima nuclear accident. Building on in-depth interviews with organization members and extensive multi-site fieldwork (2018, 2020), the article takes shimin kagaku (citizen science in Japanese) to examine articulations of citizenship and science, while discussing citizen radiation measuring organization activities. Adopting Tsing's notion of nonscalability, it draws attention to the manifold articulations of citizenship and science, unearthing frictions embedded in Japanese science-society relations. In this way, this article outlines the diversity of notions of citizenship and science, and of citizen participatory practices in science. By bringing nonscalability to bear on an analysis of different articulations of shimin kagaku, this article encourages scientists and public authorities to engage with citizen participatory practices reflexively and responsibly by considering local articulations and knowledges.

"Data is the new oil": citizen science and informed consent in an era of researchers handling of an economically valuable resource.

As with other areas of the social world, academic research in the contemporary healthcare setting has undergone adaptation and change. For example, research methods are increasingly incorporating citizen participation in the research process, and there has been an increase in collaborative research that brings academic and industry partners together. There have been numerous positive outcomes associated with both of these growing methodological and collaborative processes; nonetheless, both bring with them ethical considerations that require careful thought and attention. This paper addresses the ethical considerations that research teams must consider when using participatory methods and/or when working with industry and outlines a novel informed consent matrix designed to maintain the high ethical standard to which academic research in the healthcare arena has traditionally adhered.

Defining drinking water metal contaminant mixture risk by coupling zebrafish behavioral analysis with citizen science.

Contaminated drinking water is an important public health consideration in New England where well water is often found to contain arsenic and other metals such as cadmium, lead, and uranium. Chronic or high level exposure to these metals have been associated with multiple acute and chronic diseases, including cancers and impaired neurological development. While individual metal levels are often regulated, adverse health effects of metal mixtures, especially at concentrations considered safe for human consumption remain unclear. Here, we utilized a multivariate analysis that examined behavioral outcomes in the zebrafish model as a function of multiple metal chemical constituents of 92 drinking well water samples, collected in Maine and New Hampshire. To collect these samples, a citizen science approach was used, that engaged local teachers, students, and scientific partners. Our analysis of 4016 metal-mixture combinations shows that changes in zebrafish behavior are highly mixture dependent, and indicate that certain combinations of metals, especially those containing arsenic, cadmium, lead, and uranium, even at levels considered safe in drinking water, are significant drivers of behavioral toxicity. Our data emphasize the need to consider low-level chemical mixture effects and provide a framework for a more in-depth analysis of drinking water samples. We also provide evidence for the efficacy of utilizing citizen science in research, as the broader impact of this work is to empower local communities to advocate for improving their own water quality.

Evaluation of citizen science contributions to radon research.

In order to reduce lung cancer due to radon exposure situations, not only authorities and organisations but also citizens may meaningfully contribute to radon mitigation actions. Citizen science (CS) initiatives are recognised for their scientific, societal and policy value related to environmental issues. The purpose of this paper is to identify which CS initiatives in the field of radon exist and evaluate to what extent these CS initiatives contribute to radon research and/or radiation protection from radon. We conducted a systematic review of internet pages and scientific literature (September-December 2020) as well as expert consultation to help us identify and assess CS initiatives on radon (September 2020-February 2021). The ten principles of the European Citizen Science Association have been used as a starting point to develop indicators for the analysis of CS contributions to radon research. The results show that there are at least eight CS initiatives in the world contributing to radon related research which comply, to some degree, with each of the ten principles. In all these initiatives citizens contributed or are contributing meaningfully to radon testing and measurements. However, most of them apply the simplest form of participation (crowdsourcing) and only one focuses on radon mitigation. Moreover, unlike CS initiatives in other environmental areas, those focusing on radon are always led by the authorities and/or universities, in a top-down manner. Yet, results confirm that both the experts in radon-related fields and the citizen scientists from radon prone areas benefit from taking part in radon CS initiatives. Experiences and lessons learned in radon related to CS initiatives are identified and discussed in order to inspire future CS initiatives potentially contributing to reducing exposure to radon as well as to the implementation of national radon action plans.

Citizen involvement in scientific activities and extension of knowledge to society / Envolvimento do cidadão nas atividades científicas e extensão do conhecimento à sociedade / Intervención del ciudadano en actividades científicas y extensión del conocimiento a la sociedad

ABSTRACT High-quality health research must involve the citizen, bringing merit, relevance, and value to research and ensuring the transfer of new knowledge or outputs to the community. This theoretical study aimed to conceptualize and discuss the role of Citizen Involvement and Extension to Society in research processes and outcomes, revealing that both concepts have different purposes. Research units and research funding agencies are promoting Citizen Involvement in all steps of the research process because it adds quality to it. Moreover, universities, research units, and researchers should extend their knowledge to society, the citizens, or the end-users as part of their social responsibility. Citizen Involvement and Extension to Society should be considered strategic areas for the development of research in general and nursing research in particular. More studies are needed to generate new knowledge and useful products to better serve the real needs of society.

Más estudios son necesarios para generar nuevos conocimientos y productos útiles con la finalidad de atender mejor a las necesidades de la sociedad.

High School Students as Citizen Scientists to Decrease Radon Exposure.

Residents in rural Kentucky (KY) and suburban Ohio (OH) expressed concerns about radon exposure and lung cancer. Although 85% of lung cancer cases are caused by tobacco smoke, radon exposure accounts for 10-15% of lung cancer cases. Academic and community members from the University of KY and the University of Cincinnati developed and pilot-tested a family-centered, youth-engaged home radon testing toolkit. The radon toolkit included radon information, and how to test, interpret, and report back findings. We educated youth as citizen scientists and their teachers in human subjects protection and home radon testing using the toolkit in the classroom. Youth citizen scientists explained the study to their parents and obtained informed consent. One hundred students were trained in human subjects protection, 27 had parental permission to be citizen scientists, and 18 homeowners completed surveys. Radon values ranged from < 14.8 Bq/m3 to 277.5 Bq/m3. Youth were interested and engaged in citizen science and this family-centered, school-based project provided a unique opportunity to further the healthy housing and quality education components of the Sustainable Development Goals for 2030. Further research is needed to test the impact of student-led, family-centered citizen science projects in environmental health as part of school curricula.

Citizen science reveals microplastic hotspots within tidal estuaries and the remote Scilly Islands, United Kingdom.

The identification of microplastic hotspots is vital to our long-term understanding of their environmental fate and distribution. Although case studies have increased globally, sampling campaigns are often restricted geographically, with poor spatial resolution. Here, we use citizen science to increase our geographical reach, which improved our understanding of microplastic distribution in estuarine and beach sediment along the south-west coast of England. Hotspots (>700 particles per kg dry sediment) were identified on the Scilly Islands and in close proximity to major metropolitan hubs (i.e. Falmouth and Plymouth). Particles extracted from the Scilly Island sites were composed of polyethylene and polypropylene. With low population density on the Isle of Scilly, hotspots may suggest that microplastics originate from distant sources, while Falmouth and Plymouth, on mainland UK, are locally supplied. This information supports the design of future campaigns and targeted mitigation strategies in areas of highest concentrations.

Baseline analysis of metal(loid)s on microplastics collected from the Australian shoreline using citizen science.

Microplastics are an emerging contaminant in aquatic environments. Information on the occurrence and characteristics of microplastics in Australia is limited and their interactions with chemical contaminants have not been addressed. Therefore, the aim of this study was to generate baseline information on the physical and chemical characteristics of microplastics on Australian shorelines to facilitate further detailed risk assessment. Field collected microplastics were categorised by colour, shape and polymer type. Plastic particles were primarily clear, blue, white and green and consisted mainly of fragments (57.80%) and pellets (30.68%). Polymer characterisation revealed that shoreline microplastics were polyethylene (53.17%), polypropylene (35.17%), polystyrene (6.61%) and polyethylene terephthalate (1.85%). Analysis of metal(loid)s found that concentrations of Mn, Cr, Cu, As, Zn and Pb were significantly higher on microplastics associated with industrial locations compared with other land uses, indicating that aged microplastics have the potential to adsorb toxic metals and that metals levels may be location-dependent.

Priorities for Patient-Centered Research in Valvular Heart Disease: A Report From the National Heart, Lung, and Blood Institute Working Group.

Over the past decade, the field of valvular heart disease (VHD) has rapidly transformed, largely as a result of the development and improvement of less invasive transcatheter approaches to valve repair or replacement. This transformation has been supported by numerous well-designed randomized trials, but they have centered almost entirely on devices and procedures. Outside this scope of focus, however, myriad aspects of therapy and management for patients with VHD have either no guidelines or recommendations based only on expert opinion and observational studies. Further, research in VHD has often failed to engage patients to inform study design and identify research questions of greatest importance and relevance from a patient perspective. Accordingly, the National Heart, Lung, and Blood Institute convened a Working Group on Patient-Centered Research in Valvular Heart Disease, composed of clinician and research experts and patient advocacy experts to identify gaps and barriers to research in VHD and identify research priorities. While recognizing that important research remains to be done to test the safety and efficacy of devices and procedures to treat VHD, we intentionally focused less attention on these areas of research as they are more commonly pursued and supported by industry. Herein, we present the patient-centered research gaps, barriers, and priorities in VHD and organized our report according to the "patient journey," including access to care, screening and diagnosis, preprocedure therapy and management, decision making when a procedure is contemplated (clinician and patient perspectives), and postprocedure therapy and management. It is hoped that this report will foster collaboration among diverse stakeholders and highlight for funding bodies the pressing patient-centered research gaps, opportunities, and priorities in VHD in order to produce impactful patient-centered research that will inform and improve patient-centered policy and care.
