Electronic and electrical waste threaten environment safety if it is not mange in a proper way. Electronic circuit boards, cathode ray tubes, batteries, wires, resistors, capacitors and other internal parts contain toxic metals and toxic chemicals.
More than 70% of the heavy metals, including mercury, cadmium, tin and lead found in landfills, are coming from electronic waste. These metals and other toxic electronic components pollute groundwater and soil.
When these highly toxic wastes are burned, gases such as: carbon oxides, sulfur oxides, and nitrogen oxides are formed by their reaction with volatile organic compounds Known as ground ozone, and also produces halogens, dioxins and furans
