Established causes of diabetes do not fully explain the present epidemic. High-level arsenic exposure has been implicated in diabetes risk, but the effect of low-level arsenic exposure in drinking water remains unclear. The researchers sought to determine whether long-term exposure to low-level arsenic in drinking water in Denmark is associated with an increased risk of diabetes using a large prospective cohort.

The objective of the study was to assess the extent of arsenic contamination of groundwater and surface water in Peru and, to evaluate the accuracy of the Arsenic Econo-Quick™ (EQ) kit for measuring water arsenic concentrations in the field.

Exposure to disinfection by-products (DBPs) has been demonstrated to impair male reproductive health in animals, but human evidence is limited and inconsistent. The researchers examined the association between exposure to drinking-water DBPs and semen quality in a Chinese population.

This article analyses the water, sanitation and hygiene situation in slum households and compares it with the non-slum urban households using data from the 2011 Census. It argues for a shift from the mere water supply coverage to an emphasis on quality water distribution. Intermittent water supply coupled with poor sanitation contributes to higher health risks. Promoting point-of-use water treatment and basic hygiene practices on safe handling and storage of water are important preventive health interventions.
