In the last decade, studies were conducted on the coastal line pollution in India by the scientists from our laboratory and also jointly with our collaborators in China, by collecting and analyzing the samples like, atmospheric air, mussels and coastal marine mammals (Ramu et al, 2007;Zhang et al, 2008;Kajiwara et al, 2006;Paromita et al, 2010) for the analysis of some classical and novel organohalogen compounds.…”

“…Recent status of organohalogen pollution in the marine mammal samples collected along the coastal length of India Kajiwara et al (2006) measured the levels of PBDEs, PCBs, DDTs, CHLs, HCHs and HCB in 56 marine mammal specimens archived in the Environmental Specimen Bank of Ehime University including 2 specimens of Indo-Pacific humpback dolphins and 3 specimens of Spinner dolphins collected from the coastal regions of Bay of Bengal, and found that the PBDEs levels were the lowest in the blubber of the marine mammals from India than those from Japan, Hong Kong and the Philippines. HCHs which were found to be the highest in the green mussel samples from the same area in Bay of Bengal (Ramu et al, 2007) were the lowest in the marine mammal specimens of the study by Kajiwara et al (2006) showing its lower bioavailability and/or the easy degradation in higher animals. DDTs were also lower in marine mammals from India than those from Hong Kong, a pattern similar to that observed in the case of mussels also.…”

“…The total concentrations of PBDEs ranged from 230 to 980 ng g − 1 lipid weight in the blubber of finless porpoises and from 280 to 6000 ng g − 1 lipid weight in the blubber of humpback dolphins. Recently, the geographical distribution of PBDEs in small cetaceans from Asian waters was reported based on samples collected from 1990 to 2001 and archived in the Environmental Specimen Bank for Global Monitoring (es-BANK) (Kajiwara et al, 2006a). The PBDE concentrations ranged from 6.0 to 6000 ng g − 1 lipid weight (Table 3).…”

Polybrominated diphenyl ethers (PBDEs) have been extensively used as flame retardants in consumer goods. Sufficient evidence shows that PBDEs have been rapidly accumulating in the environment worldwide. In Asia, deca-bromodiphenyl ether has been produced and used in large quantities, while penta-BDE has largely ceased in the mid-1990s. This paper summarizes and critically reviews the status of PBDE pollution in East Asia, with emphases on the comparisons with Europe and North America and the interpretation of the differences. In general, the concentrations of PBDEs in atmosphere, sludge, human and biological samples of East Asia are comparable to or lower than those in Europe and North America. However, in the sediments of waters near densely populated and heavily industrialized areas, PBDE levels are among the highest ever reported in the literature. In Japan and China, concentrations of PBDEs in sediment cores showed an increasing trend for the past 20-30 years. Also, PBDEs levels in human breast milk in Japan increased about 10-fold in the past 20 years. The presence of PBDEs in fur seal has increased about 150-fold in 1994 than that in 1972. Regional and inter-continental transport cannot be confirmed due to insufficient information. However, the detection of a number of PBDE congeners in a pristine lake on the Qinghai-Tibet Plateau may be an evidence of their long-range transport.

Harbour porpoises and harbour seals present differences in the accumulation of polychlorinated biphenyls and polybrominated diphenyl ethers. a r t i c l e i n f o a b s t r a c tHarbour porpoises (Phocoena phocoena) and harbour seals (Phoca vitulina) are two representative top predator species of the North Sea ecosystem. The median values of sum of 21 polychlorinated biphenyl (PCB) congeners and sum of 10 polybrominated diphenyl ether (PBDE) congeners were 23.1 mg/g lipid weight (lw) and 0.33 mg/g lw in blubber of harbour seals (n ¼ 28) and 12.4 mg/g lw and 0.76 mg/g lw in blubber of harbour porpoises (n ¼ 35), respectively. For both species, the highest PCB concentrations were observed in adult males indicating bioaccumulation. On the contrary, the highest PBDE concentrations were measured in juveniles, likely due to better-developed metabolic capacities with age in adults. A higher contribution of lower chlorinated and non-persistent congeners, such as CB 52, CB 95, CB 101, and CB 149, together with higher contributions of other PBDE congeners than BDE 47, indicated that harbour porpoises are unable to metabolize these compounds. Harbour seals showed a higher ability to metabolize PCBs and PBDEs.
