How does electronics affect the environment?
A study published in Environmental Monitoring and Assessment looked at improper e-waste recycling in India and found which processes and exact parts of electronics lead to hazardous environmental contamination. For example, the study revealed that cathode ray tubes, which are found in televisions, when broken or the yoke is removed, cause environmental hazards from elements such as lead and barium, which leach into groundwater and release toxic phosphor. Printed circuit boards have to go through the process of desoldering and removal of computer chips, which has the occupational hazard of inhaling tin, lead, brominated dioxin, and mercury. Chips and gold-plated parts are processed through a chemical strip that uses hydrochloric and nitric acid, and the chips are then burned. This may lead to the release of hydrocarbons and brominated substances being discharged directly into rivers or banks. 8
