Quel est l’impact du retraitement des déchets électoniques (DEEE) dans les pays émergents ?
Une récente étude internationale s’alarme des niveaux de pollutions tout en constatant que quelques techniques simples à mettre en place limiteraient considérablement les risques sanitaires pour les travailleurs et les populations attenantes.
Titre de l’étude : A review of the environmental fate and effects of hazardous substances released from electrical and electronic equipments during recycling: Examples fromChina and India
Résumé : With the increasing global legal and illegal trade of waste electrical and electronic equipment (WEEE) comes an equally increasing concern that poor WEEE recycling techniques, particularly in developing countries, are generating more and more environmental pollution that affects both ecosystems and the people living within or near the main recycling areas. This review presents data found in the scientific and grey literature about concentrations of lead (Pb), polybrominated diphenylethers (PBDEs), polychlorinated dioxins and furans as well as polybrominated dioxins and furans (PCDD/Fs and PBDD/Fs) monitored in various environmental compartments in China and India, two countries where informal WEEE recycling plays an important economic role.
Although the data presented are alarming, the situation could be improved relatively rapidly by the implementation of more benign recycling techniques and the development and enforcement ofWEEE-related legislation at the national level, including prevention of unregulated WEEE exports from industrialised countries.
