hey their here is your answer..
==================
E-waste contains both hazardous and non-hazardous substances in their components. Globally, the e-waste generation is estimated at 20 to 50 million tonnes annually. It represents 1 to 3% of the global municipal waste produced as 1636 million tonnes per year.
The obsolete and EOL electrical and electronic equipment in large numbers made it a fast growing waste all over the world increasing at the rate of 3 to 5% per annum with respect to the municipal waste.
The presence of organic toxic and hazardous substances in e-waste separates it from the normal municipal waste. These hazardous substances like plastic, lead, mercury, cadmium, arsenic etc. pose health hazards on the human being to the most when treated in uncontrolled condition via air, water and soil.
