“…Low levels of organochlorine pesticides were detected at all sites, well below the threshold associated with 10% eggshell thinning. Interestingly, PBDE residues in eggs were greatest near the Blue Plains WWTP on the Potomac River, which suggests that wastewater discharge and sewage sludge are a source of continued input of PBDEs to the environment (LaGuardia et al, 2010). While total PCB concentrations declined at some sites, they remain high in Baltimore Harbor/Patapsco River and continue to drive fish consumption advisories in Chesapeake Bay (MDE, 2014;VDH, 2009).…”

The last large-scale ecotoxicological study of ospreys (Pandion haliaetus) in Chesapeake Bay was conducted in 2000-2001 and focused on U.S. EPA-designated Regions of Concern (ROCs; Baltimore Harbor/Patapsco, Anacostia/middle Potomac, and Elizabeth Rivers). In 2011-2012, ROCs were re-evaluated to determine spatial and temporal trends in productivity and contaminants. Concentrations of p,p'-DDE were low in eggs and below the threshold associated with eggshell thinning. Eggs from the Anacostia/middle Potomac Rivers had lower total PCB concentrations in 2011 than in 2000; however, concentrations remained unchanged in Baltimore Harbor. Polybrominated diphenyl ether flame retardants declined by 40%, and five alternative brominated flame retardants were detected at low levels. Osprey productivity was adequate to sustain local populations, and there was no relation between productivity and halogenated contaminants. Our findings document continued recovery of the osprey population, declining levels of many persistent halogenated compounds, and modest evidence of genetic damage in nestlings from industrialized regions.

“…The ENEV values of 31 ng g -1 dw for penta-BDE and 9,100 ng g -1 dw for octa-BDE were derived by Environment Canada (2006). Guidelines for interpreting HQ values are as follows: HQ \ 0.1 indicates no eco-toxicological risk and 0.1 \ HQ \ 1 indicates low eco-toxicological risk and 1 \ HQ \ 10 indicates moderate eco-toxicological risk and HQ [ 10 indicates high ecotoxicological risk (Chen et al 2010).…”

Concentrations and risk assessment of polychlorinated biphenyls and polybrominated diphenyl ethers in surface sediments from the East Lake, China

et al. 2014

The concentrations of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in surface sediment samples collected from the East Lake, China in winter 2012 and summer 2013 were analyzed in this study. The total PCB and PBDE concentrations ranged from not detected to 107.1 ng g(-1) dw and from 9.7 to 151.3 ng g(-1) dw, respectively. PCB-28, 101 and 180 were dominant congeners in both winter and summer. BDE-28 (44 %) was the dominant congener in winter and summer, followed by BDE-99 (28 %) and BDE-47 (26 %). The concentrations of PCBs in the sediment samples collected in summer were higher than those in winter, while the concentrations of PBDEs did not show much seasonal variations. Source analysis showed that the PCBs probably originated from urban runoff, industrial pollution and atmospheric deposition, and the PBDEs probably originated from historical usage of penta-BDE mixtures. Potential eco-toxicological risks caused by PCBs were found in about 5 % of the sampling sites; PBDEs had moderate eco-toxicological risk in 80 % sampling sites in the East Lake, China.

“…It is expected that most of these contaminants, once in the environment, can accumulate in living organisms (Covaci et al, 2011). The species-specific nature of bioaccumulation of OHPs has been reported in various field studies (Chen et al, 2010;Sun et al, 2014), with bioavailability and biotransformation being suggested as the likely reasons for this. The differing living and feeding habits of animals are also highlighted as important factors in determining the OHP profiles.…”
