Global baseline pollution studies IX: C6 – C14 organochlorine compounds in surface-water and deep-sea fish from the Eastern North Atlantic

Organochlorine Pesticides and Polychlorinated Biphenyl Congeners in Ooligan Grease: A Traditional Food Fat of British Columbia First Nations

“…The relatively high levels of chlordane found in ooligan grease samples in comparison with other persistent organic pollutants, (e.g., DDT and PCB) are of interest, because this contaminant is believed to be a unique characteristic of marine environment in polar regions. The total chlordane/total PCB ratio in this study was about 1.0, which is similar to the ratio found in marine fish in the Arctic (Muir et al, 1988) and Antarctica (Kawano et al, 1986) and much higher than the ratios (0.02-0.2) found in salmon, red fish, and herring oil from the North Atlantic and in herring and char from the Baltic (Zitko, 1978;Jansson et al, 1979;Miolanen et al, 1982;Kramer et al, 1984). The relatively high chlordane/PCB ratio in ooligan grease from the B.C.…”

Polychlorobiphenyl and pesticide residues in monkfish Lophius piscatorius and black scabbard Aphanopus carbo from the Rockall Trough

“…The only authors reporting organic contaminant concentrations in deep-sea black scabbard are Kramer et al (1984), who analysed one fish 106 cm long caught off Madeira at a depth of about 800 m. The levels they reported are 10-30 times higher than those measured during this study. Results documented from studies of other deep-water fish failed to cover the same species as the current study, so any comparisons would include inter-species differences, habitat and behaviour differences as well as location of capture, among other factors.…”

“…Few studies have reported concentrations of organochlorine compounds in deep-sea organisms (Barber and Warlen, 1979;Kramer et al, 1984;Lee et al, 1997;Berg et al, 1997), probably because of the difficulty in obtaining samples and the relatively limited commercial interest (until relatively recently). This study was aimed at providing a consistent preliminary data set on levels of PCBs and OCPs in black scabbard (Aphanopus carbo) and monkfish (Lophius piscatorius) from the Rockall Trough, west of Scotland.…”

Occurrence of organochlorine contaminants in tissues of the coelacanth Latimeria chalumnae

“…In biota there are reports of organochlorines in fishes from a number of locales, including: the Atlantic (Harvey et al 1973, Kramer et al 1984, Bering Sea (Takagi et al 1975), southeastern Pacific (Tanabe et al 1980), Antarctic (Subramanian et al 1983) and Arctic (Muir et al 1988) oceans. Results have generally centered on residues in muscle or liver tissue.…”
