include:Gases from fridges, AC and cooling equipmentCircuit boards containing heavy metals such as lead & cadmium
BatteriesCathode ray tubes Brominated flame-retardants used in printed circuit boards, cables and plastic casing.Slide36
Toxic components in
ewaste
include:Poly Vinyl Chloride (PVC) coated copper cables and plastic casings that release highly toxic dioxins & furans when burned
