RESUMO

The impact that cancer disease can have on individuals varies depending, among other things, on their personal characteristics, so it is important to explore aspects such as the personality traits in relation to mental health in people with cancer. The aim of this study was to analyse the relationship between neuroticism, extraversion and mental health in people with cancer. Besides, this study also explored differences in mental health when combining extraversion and neuroticism levels. One hundred and seventy people who had been diagnosed with different types of cancer (breast cancer, lung, colon, gynaecological cancer and others) composed the sample. Almost all of them (92.9%) had received oncological treatment. The GHQ-12 scale was used to assess the mental health and the 60-item NEO Five-Factor Inventory was applied in order to measure neuroticism and extraversion in participants. A hierarchic lineal regression model was conducted. Neuroticism and extraversion did not show any interaction effect, although a partial mediation was observed in relation to mental health outcomes. Given the significant correlation between neuroticism and extraversion with mental health (r = .59, p < .001; r = -.41, p < .001), both personality traits were combined, resulting in a classification of four different personality profiles (F (4;165) = 19.85; p < .001). Results in this study have shown that low levels of neuroticism and high levels of extraversion are related to positive health outcomes. They seem to be protective factors with respect to the mental health in people with cancer. The knowledge of the positive effects of these aspects contributes to the comprehension of mental health in the oncological sample, which should be considered in order to design and guide particular therapeutic interventions adapted to each person.

RESUMO

The authors discuss the geochemical behavior of arsenic (As), antimony (Sb), and selenium (Se) in urban gardens and the human health implications associated with urban agriculture. A total of 42 samples from 7 urban gardens in Madrid, Spain, were collected from the top 20 cm of soil. Concentrations of As, Sb, and Se and the main soil properties (i.e., total iron, pH, texture, calcium carbonate, and organic matter) were determined. A significant correlation was found between As and Sb and calcium carbonate, indicating the possibility of surface adsorption or ligand exchange with the carbonate group. Also, Sb seemed to form stable chelates with soil organic matter. On the other hand, Se showed a significant association with clay and iron content. The concentration of Sb in soil exceeded the recommended value for agricultural use in 70% of the urban gardens. A human health risk assessment resulted in acceptable levels of both noncarcinogenic and carcinogenic risks (although with elevated values of the latter), with As as the main risk driver and soil and food ingestion as the main exposure pathways. The numerical results of the risk assessment should be interpreted with caution given the considerable uncertainties in some exposure variables and the lack of quantitative values for the suspected carcinogenicity of Sb and Se.

RESUMO

Colombia is one of the largest per capita mercury polluters in the world as a consequence of its artisanal gold mining activities. The severity of this problem in terms of potential health effects was evaluated by means of a probabilistic risk assessment carried out in the twelve departments (or provinces) in Colombia with the largest gold production. The two exposure pathways included in the risk assessment were inhalation of elemental Hg vapors and ingestion of fish contaminated with methyl mercury. Exposure parameters for the adult population (especially rates of fish consumption) were obtained from nation-wide surveys and concentrations of Hg in air and of methyl-mercury in fish were gathered from previous scientific studies. Fish consumption varied between departments and ranged from 0 to 0.3 kg d(-1). Average concentrations of total mercury in fish (70 data) ranged from 0.026 to 3.3 µg g(-1). A total of 550 individual measurements of Hg in workshop air (ranging from
