| Polybrominated diphenyl ethers (PBDEs) as additive flame retardants in polymers, are used in a wide range of materials such as electric and electronic equipment, textiles, paint, and furniture. Since these chemicals are not chemically bound, they may ‘leak’ from the polymer product, thus invading the environment through production, use, and recycling of products containing PBDEs.
Due to environmental pollution and health concerns, the EU has issued two environmental directives in February 2003:
1. Directive on Waste Electrical and Electronic Equipment (WEEE Directive 2002/96/EC)
2. Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (ROHS Directive 2002/95/EC). PBDEs comprise one of six highly hazardous substances in the ROHS.
This application describes the use of a Thermo Scientific single quadrupole GC/MS system, used in sequential full scan/selected ion monitoring (SIM). This technique allows for the acquisition of both full scan and SIM data in a single injection, and 21 PBDE congeners were accurately identified and quantified, with detection limits ranging from fg to sub-pg levels on-column, depending on the congener.
