Suicide behaviour and arsenic levels in drinking water: a possible association?: A review of the literature about the effects of arsenic contamination in drinking water on suicides.

A considerable part of the global population is exposed to arsenic-contaminated drinking water which is the main source of inorganic arsenic(As) exposure in humans. Arsenic exposure interferes with the action of enzymes, essential cations, and transcriptional events in cells throughout the body, and a multitude of multisystemic non-cancer effects might ensue. The aim of our review was to evaluate the effects of arsenic contamination in drinking water on suicides rates.

Onsite defluoridation system for drinking water treatment using calcium carbonate.

Fluoride in drinking water has several effects on teeth and bones. At concentrations of 1-1.5 mg/L, fluoride can strengthen enamel, improving dental health, but at concentrations above 1.5 to 4 mg/L can cause dental fluorosis. At concentrations of 4-10 mg/L, skeletal fluorosis can occur. There are many areas of the world that have excessive fluoride in drinking water, such as China, India, Sri Lanka, and the Rift Valley countries in Africa. Treatment solutions are needed, especially in poor areas where d...

Trace analysis of parabens preservatives in drinking water treatment sludge, treated, and mineral water samples.

Bioanalytical assessment of adaptive stress responses in drinking water: A predictive tool to differentiate between micropollutants and disinfection by-products.

Drinking water can contain low levels of micropollutants, as well as disinfection by-products (DBPs) that form from the reaction of disinfectants with organic and inorganic matter in water. Due to the complex mixture of trace chemicals in drinking water, targeted chemical analysis alone is not sufficient for monitoring. The current study aimed to apply in vitro bioassays indicative of adaptive stress responses to monitor the toxicological profiles and the formation of DBPs in three drinking water distribut...

Nitrate in drinking water and colorectal cancer risk: A nationwide population-based cohort study.

Nitrate in drinking water may increase risk of colorectal cancer due to endogenous transformation into carcinogenic N-nitroso compounds. Epidemiological studies are few and often challenged by their limited ability of estimating long-term exposure on a detailed individual level. We exploited population-based health register data, linked in time and space with longitudinal drinking water quality data, on an individual level to study the association between long-term drinking water nitrate exposure and colore...

Feeding begets drinking: insights from intermittent feeding in snakes.

An important question related to survival of dehydrating animals is whether feeding provides a net gain of water - contributing postprandial free water and metabolic water - or, alternatively, whether digestion and assimilation of ingested food incur a net loss of water because of requirements for digestion and the excretion of resulting metabolic wastes. Here I address the question whether voluntary drinking increases or decreases following the ingestion of food. Increased postprandial drinking implies tha...
