TL;DR: In this article, the authors conducted an exploratory analysis investigating the associations between 17 geogenic trace elements (Ba, Co, Eu, I, Li, Mo, Rb, Re, Rh, Sb, Sc, Se, Si, Sr, Ti and U) found in Danish drinking water and the risk of developing ADHD.

TL;DR: In this article, the authors investigated exposure to ambient particulate matter with an aerodynamic diameter of less than 2.5 μm during childhood and subsequent self-harm risk and found that exposure to 17-19 μg/m3 of PM2.5 on average per day from birth to 10th birthday was associated with a 1.45 fold (95% CI 1.37-1.53) increase in selfharm risk.

TL;DR: In this paper, a population cohort of 2 million native Danes comprising all those born on 1st January 1965, or later, living in Denmark on their 15th birthday was followed, and each indicator was associated with a higher incidence of non-affective psychosis which remained the same or was slightly reduced, if neighbourhood levels of disadvantage were lower.

TL;DR: There are methodological problems with the study of urbanisation and incidence of psychosis based on data from the excellent Swedish population registers, but Sundquist et al argue that the prospective nature of their data allowed them to focus on urbanisation.
