Abstract:
Aim of the work was to investigate the
pollutants level specially Nitrate- N in the groundwater
and compare the obtained results with WHO standard.
Groundwater sample were collected from sixty wells
consists of thirty cancer patients well as case and other
thirty as control within 100 m distance from highly
affected three areas of oesophagus and stomach cancer.
Questionnaire was used for case- control study. The
determined values expressed by hazard quotient
indicate that the water pollutants and their
concentrations do not exceed unity. Chunnakam was
shown the high odds ratio which was greater than one.
But in relative risk was greater than one in all the
selected three areas. Ingestion with water is the main
pathway for nitrates than the vegetables in areas where
groundwater with high nitrate content.
