Resumo: | ||||||||
In this study the concentrations of Cu, Fe, Zn, Cd, Pb and Ni were
determined in muscle tissue and liver of three fish species (Mugil liza – mullet,
illiophagus; Micropogonias furnieri – croaker, carnivorous, and Trichiurus
lepturus – cutlassfish, piscivore), in the muscle tissue of a shrimp species
(Farfantepenaeus brasiliensis – pink shrimp, omnivore) and in muscle tissue,
entrails and eggs of a soft crab (Callinectes spp. – siri azul, omnivore) sampled
from the Ilha Grande Bay. The concentrations of the elements were determined by
inductively coupled plasma mass spectrometry (ICP-MS). The methodology
showed good accuracy and precision when tested with certified reference
materials (DORM-3 and TORT-2). The concentrations of Cu, Zn, Cd, Ni and Pb
were below the limits established by the Brazilian and American legislation for
human ingestion of fish products. The highest concentrations of Cu, Fe, Zn, Pb,
Cd and Ni were found in the crustacean samples. In fish, the highest
concentrations were observed in the liver and, in the soft crab samples, in the
entrails. Sex did not influence element accumulation in fish, but influenced the
accumulation of Cu, Fe, Zn, Cd and Ni in the soft crab. In fish, most elements did
not show any correlation to length and weight, with the exception of Pb, which
showed negative correlations in mullet and croaker and Cd which showed
negative correlations in croaker. In crustaceans, some elements also presented
negative correlations to these parameters, indicating that both in fish and
crustaceans these elements are not accumulated during organism growth. The
concentrations of the elements analyzed were statistically different in the dry and
rainy seasons.
