Carcinogenic trace metals in ground water of Bathinda district, Punjab, India

Abstract

Water is the second important source for surviving of human being on the earth because of it plays the major role in functioning of the body. in some decades decline the water quality due to the threatening of the environmental conditions and disposed untreated waste water in the water bodies which generate during the different activity in industries and human activities, which causes of increases of contamination of carcinogenic metals Include, mercury, cadmium, Arsenic, chromium, Selenium, Beryllium, Cobalt and nickel in ground water. These toxic metals Cancer causing to human being. Metals found in combined form of other element in the water. Carcinogenic metals Hg, Cr, As, Co, Cd, etc. also constituents of the earth crust. These were soluble in the percolate water, merged in the ground water. we have Evidences of carcinogens metals in the ground water of Bathinda district of Punjab. The present study attempt has been made to identify the types and concentration of different carcinogenic metallic ions present in ground water of South-Western, Bathinda district of Punjab. The pH was ranged from 6.5 -7.4 which were within the permissible limit of drinking ground water. Cr and Hg is above the permissible limit of drinking water quality guideline of WHO and BIS. Cr ranged from 70-360 ppb in ground water and highest level of Cr was observed at Lehra Mohabbat. The permissible limit in drinking water of Hg is 1ppb, all the sample have the Hg concentration level is above the limit. Expect three sites (JWS2-17.6 ppb, Bhambhia-11.9 ppb and Ganga-10.7 ppb) the concentration of Se and As was below the permissible limit.
