Cadmium in circuit boards; lead oxide and Cadmium in monitor
Cathode Ray Tubes (CRTs); Mercury in switches and flat
screen monitors; Cadmium in computer batteries;
polychlorinated biphenyls (PCBs) in older capacitors and
transformers; and brominated flame retardants on printed circuit
boards, plastic casings, cables and polyvinyl chloride (PVC)
cable insulation that releases highly toxic dioxins and furans
when burned to retrieve Copper from the wires.All electronic
equipments contain printed circuit boards which are hazardous
because of their content of lead (in solder), brominated flame
retardants (typically 5-10 % by weight) and antimony oxide,
which is also present as a flame retardant (typically 1- 2% by
weight).8
Nickel (Ni) which is present in E-waste causes skin damage,
