Isomer-specific analysis of hexabromocyclododecane by LC/MS/MS

چکیده
Hexabromocyclododecane (HBCD, C12H18Br6) is the most widely used of the cycloaliphatic BFRs. In 1999, the global demand for HBCD (~16 kilotons) was more than double that of the penta-bromodiphenyl ether (~8.5 kilotons) mixture [1]. HBCD is used as thermal insulation in the building industry, and is the principal flame retardant in extruded (XEPS) and expanded (EPS) polystyrene foams [2]. Secondary uses of HBCD are in upholstery textiles including residential and commercial furniture, upholstery seating in transportation, draperies, and wall coverings [1,2].

BACKGROUND Hexabromocyclododecane (HBCD) is a brominated flame retardant used in polystyrene foams in thermal insulation and electrical equipment. The HBCD commercial mixture consists mainly of α, β, and γ stereoisomers. Health concerns of HBCD exposure include alterations in immune and reproductive systems, neurotoxic effects, and endocrine disruption. Stereoisomer-specific levels of HBCD have...
