Screening for halogenated flame retardants in European consumer products, building materials and wastes.

摘要: Abstract To fulfill national and international fire safety standards, flame retardants (FRs) are being added to a wide range of consumer products building materials consisting flammable like plastic, wood textiles. While the FR composition some has been identified in recent years, limited global coverage data large diversity necessitates more information for an overall picture common products/materials. address this issue, 137 individual samples various products, wastes were collected. identify characterize potential sources FRs indoor environment, all analyzed content polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDDs) novel (NFRs). The most frequently detected HBCDDs (85%), with highest median concentration Σ4HBCDDs 300 mg kg−1 polystyrenes. Σ10PBDEs was found recycled plastic materials, reaching 4 mg kg−1. lowest concentrations observed NFRs, where Σ12NFRs reached 0.4 mg kg−1 group electrical & electronic equipment wastes. This suggests that currently in-use, legacy compounds still contribute burden FRs. Additionally, contrasting patterns virgin plastics, revealed using principle component analysis (PCA), suggest reentering market through perpetuating emissions environments thus human exposure.
