Abstract

Polybrominated diphenyl ethers (PBDEs) were investigated in sediments and invertebrates (gammarids and caddisflies) collected in the River Po, upstream and downstream from a polluted tributary. Besides a diffuse contamination by penta-BDE technical mixture, the river sediments identified the tributary as an important source to the main river of decabromodiphenyl ether (BDE-209), which peaked to 64 μg/g (OC) in the downstream stretch. At 10 km downstream from the tributary, a higher bioavailability was evident than at 22 km, and small gammarids accumulated at two/three times the levels of PBDEs found in large gammarids. The congener profiles of sediments and invertebrates were dominated by BDE-47, BDE-99 and BDE-209.
