Polybrominated diphenyl ethers (PBDEs) and organochlorines in small cetaceans from Hong Kong waters: Levels, profiles and distribution

High accumulation of PCDD, PCDF, and PCB congeners in marine mammals from Brazil: A serious PCB problem

“…Evaluating the body distribution of lipophilic organohalogen compounds in cetaceans, Watanabe et al (1999) and Ramu et al (2005) observed that, in general, the highest levels are found in blubber, even considering lipid normalized concentrations. However, different body distribution patterns are observed for compounds of the same chemical class (Kunisue et al, 2008).…”

PBDE levels in franciscana dolphin (Pontoporia blainvillei): Temporal trend and geographical comparison

“…Concentrations of total PBDEs in the FMA III were two orders of magnitude lower than those found in samples from the North Atlantic: Tursiops truncates from Florida coast (Johnson-Restrepo et al, 2005) and the pelagic species Lagenorhynchus acutus and Steno bredanensis (Tuerk et al, 2005); and coastal species from the China Sea (Neophocaena phocaenoides and Sousa chinensis) (Ramu et al, 2005), which are considered "hot spots" for PBDEs due to the large usage of these chemicals. However, the concentrations were similar to those found in samples from India and the Philippines , where PBDE levels are considered low.…”

A review of environmental and human exposure to persistent organic pollutants in the Pearl River Delta, South China

“…Concentrations of DDTs were 2490±2220 (453-9160), 16,100±5690 (8970-28,000), 9220±15,100 (601-49,000), and 4760±6110 (400-21,800) ng/g lw in eggs of Night Heron, Great Egret, Little Egret plus Chinese Pond Heron, and Chinese Pond Heron, respectively, collected from Hong Kong in 2006 . In addition, levels of DDTs were 9.9-260 (mean: 111) ng/g lw, 19-470 (mean: 158) ng/g lw, and 0.60-23.6 (mean: 2.4) ng/g ww in blubber of finless porpoise, blubber of humpback dolphin, and in Chiloscyllium plagiosum muscle, respectively, whereas those of HCHs were 0.032-0.96 (mean: 0.25) ng/g lw, 0.11-2.2 (mean: 0.66) ng/g lw, and 0.009-0.063 (mean: 0.024) ng/g ww, respectively (Ramu et al, 2005;Cornish et al, 2007). Consistent with results for birds and bird eggs, p,p′-DDE and β-HCH were also the predominant constituents of DDTs and HCHs, respectively, in aquatic mammals (Ramu et al, 2005).…”
