Exposure at high concentrations, even for less than a minute, causes the gas to attack the eyes and mucous membranes; this causes cold-like symptoms for at least a few days afterwards. In Germany, the limit in drinking water is 0.008 mg/L, and the US EPA recommends a maximum contamination of 0.01 mg/L. [ 8 ] [ 12 ]
The USGS defined the biogeochemical pathway of selenium moving "from rock to duck” as the 'Kesterson effect". [13] The group of symptoms and effects observed in birds from research at Kesterson Reservoir is known as "Kesterson Syndrome". [14] Selenium is a naturally occurring element in the environment, and is an essential dietary nutrient.
People who eat more fish are generally healthier than those who eat less, [101] which suggests no major human health concern from selenium pollution, although selenium has a potential effect on humans. [102] Selenium poisoning of water systems may result whenever new agricultural run-off courses through dry lands. This process leaches natural ...
The source of the contamination has been attributed to "corrosion in the lead and iron pipes that distribute water to city residents". [58] In 2015, the lead concentration of drinking water in north-eastern Tasmania, Australia, reached a level over 50 times the prescribed national drinking water guidelines. The source of the contamination was ...
A small number of people in the United Arab Emirates have shown symptoms associated with contaminated water after heavy rains and floods, the health ministry said. There have been "a very limited ...

It gets into rivers and lakes from the stools of infected animals. Municipal water treatment plants usually remove Cryptosporidium oocysts through filtration. Nevertheless, at least five outbreaks of cryptosporidiosis in the U.S. have been associated with contaminated drinking water, including a well-publicized one in Milwaukee, Wisconsin in ...
