Malik, Riffat Naseem and Moeckel, Claudia and Jones, Kevin C. and Hughes, David (2011) Polybrominated diphenyl ethers (PBDEs) in feathers of colonial water-bird species from Pakistan. Environmental Pollution, 159 (10). 3044 - 3050. ISSN 0269-7491Full text not available from this repository.
Feathers of two colonial water-birds species (Bubulcus ibis, Egretta garzetta) from four heronries in the Punjab province, Pakistan were analysed for 28 Polybrominated Diphenyl Ethers (PBDEs) congeners. Median concentrations of âˆ‘PBDEs were 2.41 and 1.91Â ng/g in little and cattle egrets. PBDE-47, -100, -138, -153 were abundant and detected in >70% of feather samples in both species. Species-specific differences based on dietary preferences indicated higher concentration of PBDE-47, -66, -75, -100, -153, -154, and -183 in fish eating little egret. BDE-47 and -100 were more frequent in little egrets and BDE-99 was more dominant in cattle egret which feed on terrestrial habitat. Higher âˆ‘hexa- and hepta-BDEs congeners showed larger concentrations in feathers from heronries close to water bodies which receive urban and industrial effluents whereas lower-brominated congeners (BDE-47â€“BDE-100) dominated in rural/agricultural regions. Hazard quotients (HQs) indicated that measured âˆ‘PBDEs pose no risk to egret population.
