摘要

Organophosphorus compounds (OPs) and tetrabromobisphenol A (TBBPA) are widely utilized as flame retardants (FRs) in plastics, textiles, rubbers, and building materials. Eight OPs and TBBPA were quantified by GC/MS from air samples collected from a furniture workshop, a circuit board factory, two electronics dismantling facilities, a computer classroom, and offices and social premises. In addition, dermal exposure was assessed with patch and hand wash samples at some workplaces. Triphenyl phosphate, tris(2-chloroethyl) phosphate, andtris(2-chloroisopropyl) phosphate were typical contaminants of the workplaces, whereas TBBPA, tricresyl phosphate, tri-n-butyl phosphate, and tris(2-ethylhexyl) phosphate were rather site-specific. The highest geometric mean of totalFRs in the air samples was measured in personal samples atthe electronics dismantling facilities (2.9 and 3.8μg/m~3), whereas the stationary sample results from the other environments ranged between 90 and 720 ng/m~3. Stationary samplings underestimated the personal exposure at three out of four work places where comparisons were made. Dermal exposure was shown for the first time at these occupational settings. The geometric mean of totalFR levels in patch samples ranged between 1.5 and 24 ng/cm~2 and in hand wash samples between 3.5 and two hands. The health effects of the measured FR levels remain unknown.
