PHYSICO-CHEMICAL ANALYSIS OF HEAVY METAL CONTAINING EFFLUENTS

Industrial Effluents entering the water bodies is one of major sources of environmental toxicity. It not only affects the quality of drinking water but also has deleterious impact on the soil microflora and aquatic ecosystems. The south Gujarat area is “Toxic Hotspot” in the state. In the presence study we collected effluent sample From Different Industrial area near Vapi Gujarat .The parameters such as temperature, of the water have been studied using standard protocol APHA. The levels of heavy metal pollution such as mercury (Hg), Arsinate (As) and Nickel (Ni) were determined by using Atomic Absorption Spectrophotometer (AAS). The physicochemical analysis reveals that the all the samples are polluted and having the values higher than the permissible limits. Some remedial steps to be taken for avoiding water pollution.
