Mercury is a naturally occurring element that occurs in water, soil and air. Mercury has toxic effects on the nervous, digestive, immune system, lungs, kidney, skin and eyes. World Health Organisation (WHO) reports that even a small amount of Mercury can lead to serious health problems and is also a threat to the development of children in utero as well as in their early life. As per the WHO norms, the naturally occurring level of Mercury in groundwater and surface water is less than 0.5 µg/litre (0.5 ng/ml) [1]. A small number of groundwater and shallow wells have been surveyed in the USA which shows to have Mercury levels that exceeds the maximum contaminant level of 2 µg/litre (2 ng/ml) set by the US Environmental Protection Agency for drinking water [1]. Therefore, high sensitivity detectors are required to timely detect the nano level of Mercury in drinking water.
