| Abstract | Background: Elasmobranchs are particularly vulnerable to environmental metal contamination, accumulating
these contaminants at high rates and excreting them slowly. The blue shark Prionace glauca L. is one of the most
heavily fished elasmobranchs, although information regarding metal contamination and detoxification in this
species is notably lacking.
Methods: Blue sharks were sampled in the western North Atlantic Ocean, in offshore waters adjacent to Cape Cod,
Massachusetts. Total and metallothionein-bound liver and muscle metal concentrations were determined by
inductively coupled plasma mass spectrometry (ICP-MS), metallothionein detoxification and oxidative stress
endpoints were determined by UV–vis spectrophotometry.
Results: Metallothionein detoxification occurred for As, Cd, Cs, Cu, Hg, Pb, Se, Ti and Zn in liver, and for As, Cd,
Cs, Pb, Se, and Zn in muscle, while reduced glutathione defenses seem to be related to Co and Zn exposure.
Conclusion: This is the first report for several metals (Ag, Co, non-radioactive Cs, Sb, Ti and V) for this species,
which will aid in establishing baseline elemental data for biomonitoring efforts, health metrics, and conservation
measures. | pt_BR |
