ESTIMATION OF NITRATE, NITRITE, ARSENIC AND OTHER PHYSIC-CHEMICAL PROPERTIES OF WATER
Contamination of drinking water by nitrates, nitrites and arsenic is an evolving public health concern since nitrate can undergo endogenous reduction to nitrite and nitrosation of nitrites can form N-nitroso compounds which are potent carcinogens. Nitrites can lead among infants to the disease called methemoglobinemia (blue baby syndrome). There is a strong relationship between nitrate concentration and recurrent diarrhoea and also other illness. The objective of this study is investigation and determination of nitrate, nitrite, arsenic and other physic-chemical parameters of Bagalkot district. 46 samples of water were analysed for pH, total hardness, chloride, fluoride, iron, total alkalinity, nitrate, nitrite, arsenic and sulphates. It was found that water samples had within the permissible limits of WHO.
