Exposure of Canadian electronic waste dismantlers to flame retardants

Popis výsledku v původním jazyce

Exposure of e-waste workers to eight halogenated and five organophosphate ester flame retardant chemicals (FRs) was studied at a Canadian e-waste dismantling facility. FR concentrations were measured in air and dust samples collected at a central location and at four work benches over five-24 hour periods spanning two weeks. The highest concentrations in air from workbenches were of BDE-209 (median 156 ng m(-3)), followed by Tris(2-chloroethyl) phosphate (TCEP, median 59 ng m(-3)). Dust concentrations at the workbenches were higher than those measured at the central location, consistent with the release of contaminated dust during dismantling. Dust concentrations from the workbenches were also dominated by BDE-209 (median 96,300 ng g(-1)), followed by Triphenyl phosphate (TPhP, median 47,000 ng g(-1)). Most FRs were in coarse particles 5.6-18 mu m diameter and similar to 30% were in respirable particles (&lt; similar to 3 mu m). Exposure estimates indicated that dust ingestion accounted for 63% of total FR exposure; inhalation and dermal absorption contributed 35 and 2%, respectively. Some air and dust concentrations as well as some estimated exposures in this formal facility in a high-income country exceeded those from informal e-waste facilities located in low and middle income countries. Although there is demonstrated toxicity of some FRs, FR exposure in the e-waste industry has received minimal attention and occupational limits do not exist for most FRs.
