<p><span style="font-size:14px"><span style="font-family:Arial,Helvetica,sans-serif">Several electroplating industry including agricultural sector industries, sewage treatment and mining operations all combine to generate hazardous waste water containing enormous amounts of toxic heavy metals. The accumulations of these toxic heavy metals in human beings, animal cause many metabolic disorders. Heavy metal concentration was estimated in sewage, sludge and electroplating wastewater collected from Karnal, Panipat, and Sonepat districts of Haryana. Heavy metals were estimated by Atomic Absorption Spectrophotometer. The results showed that Cd, Cr, Pb and Ni were not found in any studied industrial effluent, sludge, and sewage samples, while some of the following soluble heavy metals ranged from: Cd (0.015 - 0.451 mg/L), Cr (0.015 - 0.248 mg/L), Pb (0.014 - 0.351 mg/L) and Ni (0.023 - 0.624 mg/L). Similarly total heavy metal ranged from: Cd (0.2 &ndash; 6.5 mg/L), Cr (0.1- 180 mg/L), Pb (0.1 - 180 mg/L) and Ni (0.3-125 mg/L).</span></span></p>
