HAZARDOUS MATERIALS IN THE e-WASTE (Electronic products/components contain, chlorinated solvents, BFR, PVC, heavy metals, plastics and glasses)

Computer circuit boards: Pb, Cd

Computer batteries, semi conductors: Cd, Ni

Printed circuit boards, cables and plastic casings: BFRs, Sb2O3, PVC (when burned releases toxic furans and dioxins)

Switches, flat screens, housing: Hg

Old capacitors/transformators: PCBs

CRT glass: Pb (%25), Ba, As

Power suppy: Se

Stell parts: Cr (corrosion), Co (magnetivity)

Lead (Pb):  cause damage to the nervous and blood  systems and kidney in humans, accumulates in the environment, and has acute and chronic toxic effects on plants, animals and microorganisms. Children suffer developmental effects and loss of mental/brain ability, even at low levels of exposure.

      Consumer electronics constitute 40% Pb found in landfills. The main concern in regard to the presence of Pb in landfills is the potential for the Pb to leach and contaminate drinking water supplies. The main applications of Pb in electronics are soldering  of printed circuit boards and other electronic components and  CRTs.
