Abstract
One hundred and sixteen sewage sludge samples from 22 municipal wastewater
treatment plants in Sweden were analysed for brominated flame retardants.
Polybrominated diphenyl ethers (PBDEs)were in the range n.d.-450 ng/g wet
weight, tetrabromobisphenol A (TBBPA) varied between n.d. and 220 ng/g wet
weight, 2,4,6-tribromophenol was in the range n.d.-0.9 ng/g wet weight and
polybrominated biphenyls were not detected (except for a possible analytical
interference). There was a significant variation in the samples among plants. Influence
from industries and other local sources can therefore be assumed. The
correlation pattern indicated contribution from three different types of
technical products; composed of either low-brominated PBDEs, decaBDE or TBBPA.
