Over the past few decades, enormous quantities of industrial
pollutants have been released into the environment. Solid waste
management, which is already a massive task in India, is
becoming more complicated by the invasion of e-waste,
particularly computer waste. Electronic-waste (e-waste)
represents electronic products including computers, printers,
photocopy machines, television sets, mobile phones, and toys,
which are made of sophisticated blends of plastics, metals, and
other materials. It is an emerging problem because of the
volumes of e-waste being generated and the content of both
toxic and valuable materials in them. The fraction including
iron, copper, aluminium, gold and other metals in e-waste is
over 60%, while plastics account for about 30% and the
hazardous pollutants comprise only about 2.70%1. Electronic
devices form a complex mixture of materials and components,
often containing several hundreds of different substances, many
of which are toxic and create serious pollution upon disposal.
These include heavy metals such as mercury, lead, cadmium,
chromium and flame retardants such as polybrominated
biphenyls (PBB) and polybrominated diphenylethers (PBDEs).
Disposal of the e-wastes is an emerging global environmental
issue, as these wastes have become one of the fastest growing
waste types in the world. The recent investigations of workers
involved in manufacturing the chips, he drives and circuit
boards are reporting health problems. Even the workers who
handle even e-waste as a scrap has health problems. The
recycling and disposal of computer waste in these countries
becomes a serious problem since their treatment methods
remain rudimentary. Such activities pose grave environmental
and health hazards; for example, the deterioration of local
drinking water which can result in serious illnesses. The
hazardousness of e-waste is well recognized, but the knowledge
on these hazards and the resulting risks associated with different
treatment options is currently fragmented. Current article
gathers the data on componenets and hazardous substances of e
-waste that are creating environmental pollution and human
exposure to these chemicals, resulting adverse effects due to
recycling, incineration and landfill disposal of e-waste. Current
study is based on different hazardous components present in ewaste,
current senerio of E waste generation. Methods which are
available and risk associated with those methods have also been
mentioned.
