ABSTRACT
The electronic waste is a heterogeneous mixture of metals, plastics, glass, computers, mobiles and telephones. The Cathode ray tube in computer monitors and Television contain 0.4 & 1 kg of heavy metals respectively. These metals are mainly Lead and Cadmium. The dismantling and disposal of electronic waste in developing countries is major concern because of its impact on the environment and risk to human health. Uncontrolled disposal of e-waste generate and release high toxic metals such as Hg, Pb, Cd, and chromium and high concentrations of different types of flame retardants such as Poly Brominated Diphenyl Ethers (PBDEs), Organo-Chlorine Pesticides (OCPs). Heavy metal concentration in the groundwater of western Uttar Pradesh was monitored to determine their status in dismantling areas. Burning sites probably contains invaluable e-waste and abandoned sites formely involved in informal recycling activities are the new sources of ground water based environmental pollution in some districts of western UP. Most of the e-waste has their self life, after which they cannot be reused. Hence, it is essential either to recycle them or their disposal with suitable precautions.
