Some fifty different FRs were analysed in settled dust from a total of 18 informal e-waste and end-of-life vehicle processing workshops in Vietnam. FR levels were much higher for e-waste than vehicles. For e-waste, brominated FR levels showed 79 000 µg/kg, chlorinated OPFRs 6 600 µg/kg, PIN OPFRs 15 000 µg/kg (total medians). For vehicles: brominated 510, chlorinated OPFRs 570, PIN FRs 270. The authors conclude that the human health risk from such levels of FRs in dusts is low.
