Trace metal levels in sharks from British and Atlantic waters
TL;DR: In this paper, tissue samples from 46 sharks representing ten species and four locations were analysed for seven trace metals (Cu, Mn, Fe, Cd, Ni, Pb, Zn) using atomic absorption spectrophotometry.
Journal ArticleDOI
Comparison of the bioaccumulation from seawater and depuration of heavy metals and radionuclides in the spotted dogfish Scyliorhinus canicula (Chondrichthys) and the turbot Psetta maxima (Actinopterygii: Teleostei)
TL;DR: The elevated uptake rates and higher CFs for most radioisotopes indicate that S. canicula is more susceptible than P. maxima to exposure and contamination by these metals and radionuclides in seawater.

Organotropism of persistent organic pollutants and heavy metals in the Greenland shark Somniosus microcephalus in NE Greenland.
Simonetta Corsolini,Stefania Ancora,Nicola Bianchi,Giacomo Mariotti,Claudio Leonzio,Jørgen S. Christiansen,Jørgen S. Christiansen +6 more
TL;DR: The brain, liver, red and white muscle, gonads, fat, skin, pancreas, and spleen of Greenland sharks from NE Greenland fjords were analysed for PCBs, PCDDs/DFs, PBDEs; DDT isomers; HCH isomers%; dieldrin; endrin; HCB; Cd, Hg, Pb, and Se.

Oxidative stress indicators and trace elements in the blue shark (Prionace glauca) off the east coast of the Mexican Pacific Ocean.
Angélica Barrera-García,Todd M. O'Hara,Felipe Galván-Magaña,Lía C. Méndez-Rodríguez,J. Margaret Castellini,Tania Zenteno-Savín +5 more
TL;DR: Differences between sexes and maturity stages in trace element concentration and carbonyl protein levels in blue shark muscle may be related to variations in diet within different cohorts.
Journal ArticleDOI
Trace elements and oxidative stress indicators in the liver and kidney of the blue shark (Prionace glauca)
Angélica Barrera-García,Todd M. O'Hara,Felipe Galván-Magaña,Lía C. Méndez-Rodríguez,J. Margaret Castellini,Tania Zenteno-Savín +5 more
TL;DR: Differences between sex and maturity cohorts, and the interactions of trace elements with oxidative stress indicators were assessed, may be important drivers of oxidant and antioxidant processes in sharks and an important consideration in their physiology and health.

Journal ArticleDOI
British Isles coastal waters: The concentrations of selected heavy metals in sea water, suspended matter and biological indicators — A pilot survey
TL;DR: The results show that there are some areas where significant contamination exists, and the east Irish Sea appears to have the highest concentrations of most metals as mentioned in this paper, however, data in most regions indicate that the concentrations of the metals examined are not significantly higher than those in the open Atlantic Ocean adjacent to the British Isles.
Journal ArticleDOI
The levels of certain metals in fish from coastal waters around England and Wales
TL;DR: It is suggested that further studies be performed to ascertain the areas of origin of these metals and to establish the areas in which concentrations of metals found in the fish sampled were highest.
Journal ArticleDOI
Occurrence of heavy metals in the blue shark Prionace glauca and selected pelagic in the N. E. Atlantic Ocean
J. D. Stevens,B. E. Brown +1 more
TL;DR: 98% of samples analysed for lead and 73% for cadmium were below detectable limits for these metals, although individual sharks showed elevated levels in liver and gonad plus epigonal tissue.

Water quality studies around the sewage sludge dumping site in Liverpool Bay
TL;DR: The results of two studies (in 1978 and 1979) of metal concentrations in the waters of Liverpool Bay are presented and discussed as discussed by the authors, where concentrations of zinc, copper, cadmium and nickel were measured in solution and in suspension at a series of stations from the mouth of the River Mersey to seaward of the sewage sludge dumping ground.
