Analysis on site: Heavy metals

Heavy metals such as arsenic and mercury find their way into the ground water in many regions of the world, either through natural processes or as the result of human activities. Limit values are exceeded many times over, particularly for
arsenic in drinking water, in many areas. This calls for a rigorous monitoring of water quality. The present article focuses on the causes of heavy metal pollution in the environment and on field determinations of heavy metals – directly at the sampling site.
