“…This sequence indicates a high affinity for iron and copper in the shrimps. This is due to the essentiality of iron in cytochromes and protein [7] and the high affinity for copper can be attributed to its function in respiratory pigment haemocyanin [22] and metalloenzyme [6]. This finding is consistent with the sequence observed by Omoigberale and Ikponmwosa-Eweka [8] in the palaemonid shrimps of Osse River: Fe >Mn> Cu > Zn >Pb> Cd > Cr.…”

“…Cu and Zn were chosen for optimizing the method, as shellfish tend to have high levels of Cu and Zn, based on reports in published literature (Van den Broek, 1979;Singh, 1988;Guns et al, 1999;Rojas de Astudillo, 2002& Liang et al, 2004.…”

Shrimp is a popular seafood in Trinidad and Tobago which is mainly caught in the coastal environs and sold mostly for domestic consumption. The objectives of the research were to determine if chemical contaminants copper, zinc, cadmium, chromium, nickel and mercury in the marine shrimp (Penaeus spp.) met international and local food safety standards and; to investigate any location by season interactions. Determination of all heavy metals was by flame atomic absorption spectroscopy except for mercury. Validation of methods was done using Certified Reference Materials namely dogfish liver and fish protein. The heavy metal findings in the marine shrimp were well below the United States Food and Drug Administration, Canada’s Food Inspection Agency and, Trinidad and Tobago’s admissible limits for human consumption. Significant differences were observed only for copper by location and season interaction and; zinc by location and season respectively.

“…PCB levels in the gut wall of Platichthys flesus taken at the Thurrock Power Station in May 1976 closely resemble levels in animals from the Medway estuary between March 1974and April 1975(Van den Broek, 1979. Southend cockles have a similar level of PCB contamination to Mytilis edulis in the outer part of the Medway estuary (Wharfe & Van den Broek, 1978) entering the southern reach of the River Thames and also to Mytilis edulis in Liverpool Bay (Riley & Wahby, 1977).…”

Juvenile turbot, Scophthalmus maximus (L.), were exposed to 0.58/~g 1-1 Aroclor 1254 in seawater, to sediments containing 100, 60 and 1 ppm or fed with cockle containing 20 ppm PCB (polychlorinated biphenyls). Concentration factors for liver and muscle were 104 and 103, respectively, for uptake of PCB from seawater. Contamination of muscle was similar to that of sediments containing 1 and 60 ppm PCB to which turbot were exposed, but less than the 20 ppm in their experimental diet. Contamination of flatfish in the North Sea area is compared with the levels of PCB in the flounder, Platichthys flesus (L.), in the River Thames and predictable values for uptake of PCB from different pathways discussed.
