Title

AIRBORNE CONCENTRATIONS OF POLYBROMINATED DIPHENYL ETHERS IN PRIVATE CARS

English Abstract

Airborne concentrations of PBDEs were investigated using PUF disk passive air samplers in 25 private cars. ΣPBDE concentrations ranged between 0.01 and 8.2 ng m-3 with respective arithmetic and geometric mean concentrations of 0.71 and 1.87 ng m-3. High concentrations of PBDEs found in cars might provide an important source of human exposure to PBDEs either via inhalation or dust ingestion. Excluding two most contaminated cars, linear regression revealed a significant positive relationship (p<0.01) between log-normalised PBDE concentrations and vehicle age. To explain wide variation in airborne concentrations of PBDEs between cars from same manufacturer with similar ages, further monitoring of PBDE contamination in cars is warrant. The median ratio of BDE 47:99 for air samples was 1.7 comparing with the respective values of ~1 and ~0.7 reported for BK 70-5DE and DE-71, suggesting these commercial formulations to be likely sources of PBDEs in the car indoor environments.
