There is considerable scientific interest in the psychological correlates of pro-environmental attitudes and concerns. While much research has focused on demographic and social-psychological characteristics of individuals with pro-environmental attitudes, our study explores the relations between personality traits and pro-environmental behaviours. The study found that Honesty, Agreeableness, Openness, Proactive personality and Pro-environmental attitude predict environmental behaviour. The main implication of the study is the fact that responsible environmental behaviour could be enhanced through programmes focused on the increase of the environmental awareness and the development of a more pro-ecological view...

A Theory of Change (ToC) is an approach to map programmes aimed at inducing change in a specific context, with the goal of increasing their impact. We applied this approach to the specific case of handwashing and sanitation practices in low- and middle-income countries and developed a ToC as part of a systematic review exercise. Different existing sources of information were used to inform the initial draft of the ToC. In addition, stakeholder involvement occurred and peer review took place. Our stakeholders included methodological (ToC/quantitative and qualitative research) and content experts (WASH (Water, Sanitation, Hygiene)/behaviour change), as well as end-users/practitioners, policy-makers and donors...

Rare earth elements (REE) are a group of chemical elements that include lanthanoids (lanthanum to lutetium), scandium and yttrium. In the last decades, the REE demand in the industry and other areas has increased significantly. In general, REE have shown low concentrations in soils, plants, water and atmosphere, but they may accumulate in such environments due to anthropogenic inputs. In areas where there is REE contamination, the slow accumulation of these elements in the environment could become problematic...

The aim of this study was to analyze the impact of hydrodynamic forces on the multiplication of E. coli, and biofilm formation and dispersion. The experiments were provided in a flow chamber simulating a cleaning-in-place system. Biofilm biomass was measured using a crystal violet dye method. The results show that hydrodynamic forces affect not only biofilm formation and dispersion but the multiplication of E. coli in the first place. We found more biofilm biomass on the rough surface than on the smooth one...

Olfaction is a key sensory mechanism in humans. Deficits in this chemosensory function have wide-ranging impacts on overall health and quality of life. This study examines the role of environmental phenols as risk factors for olfactory dysfunction among a random sample of 839 middle-aged and older U.S. adults. Olfactory function assessment was carried out using a short 8-item test, scores on which were used to classify subjects into normal or impaired olfactory function groups. Logistic regression models were used to test for associations between olfactory impairment and creatinine-adjusted urinary levels of 8 common environmental phenols, adjusting for potentially confounding covariates...

We investigated the association between daily emergency ambulance calls (EAC) for elevated blood pressure that occurred during the time intervals of 8:00-13:59, 14:00-21:59, and 22:00-7:59, and exposure to CO, PM10 , and ozone. We used Poisson regression to explore the association between the risk of EAC and short-term variation of pollutants, adjusting for seasonality and weather variables. Before noon, the risk was associated with an interquartile range (IQR) (7.9 μg/m3 ) increase in PM10 at lag 2-4 days below the median (RR = 1...
