analytical study on the rohs of plastic from waste electrical and electronic appliances

this study was conducted to identify emission characteristics of certain hazardous substancescontained in the plastic of used home electrical and electronic appliances keeping in view compliance with therestriction of hazardous substances (rohs) directive and to estimate the possibility of safe recyclingpractices. according to the results, the concentration of cadmium, lead, mercury and chromium were foundbelow than maximum concentration value (mcv) of rohs, while the concentration of total bromine (t-br)was exceeded the standard limitations in the samples of plastic from e-waste. over 90% of the plastics usedin housing cover of display electronic products were composed of polystyrene (ps) 53.9% and ps-flameretardants 36.4%.peak of each hazardous substance in total samples also showed higher values of bromine,cadmium and lead. in order to enhance cleaner recycling of waste electronic appliances in accordance with the allowance of rohs directive, the use of brominated flame retardants in plastic and chrominated syntheticresins should be restricted and applications of metal surface finishing such as coating and painting of highmolecules synthetic resins should be minimized.
