Heavy metal analysis in water, fish and vegetative samples of lakha-banjara lake, sagar, madhya pradesh, india

The present study was conducted to assess the risk to human health by heavy metals (Pb, Cd, As) through the intake of locally caught fishes and grown vegetables from sewage fed lake water on agricultural land. Heavy metal (Pb, Cd, As) concentration in water, fish and vegetative samples were analyzed from Lakha-Banjara lake, Sagar, Madhya Pradesh, India in the pre monsoon season (May- June-2013). Heavy metal concentration in all samples were found in order Cd > Pb > As. Fish samples (Labeo rohita), Eggplant (Solanum melonjena) and Cow Pea (Vigna unguicilata) were collected from the lake surroundings and analyzed for heavy metal contents. The water samples were containing larger quantities of heavy metals and due to use of their water for irrigation and cultivation there metals are accumulated into the tissues of vegetables. The vegetative samples also showed concentration above permissible limits (WHO/FAO standard).The presence of such concentration of Pb, Cd and As in fishes and vegetables as well as water is a serious matter of concern and potential risk for human exposure to such heavy metals by eating these vegetables, fishes or even drinking such water. The present study suggests that the waste water irrigation led to accumulation of heavy metals in food stuff causing potential health risk.
