“…It is unlikely that this represents cause and effect since, for example, metal concentrations are also related to age and maturity (Lahaye et al, 2005(Lahaye et al, , 2007. Cadmium levels were higher in common dolphins than in porpoises, perhaps related to feeding in offshore waters and/or the presence of oceanic squids (which are known to accumulate large amounts of cadmium) in their diet (Bustamante et al, 1998;Lahaye et al, 2005).…”

High PCB levels were recorded in porpoises and common dolphins from European coasts. AbstractConcentrations of polychlorinated biphenyls (PCBs) in blubber of female common dolphins and harbour porpoises from the Atlantic coast of Europe were frequently above the threshold at which effects on reproduction could be expected, in 40% and 47% of cases respectively. This rose to 74% for porpoises from the southern North Sea. PCB concentrations were also high in southern North Sea fish. The average pregnancy rate recorded in porpoises (42%) in the study area was lower than in the western Atlantic but that in common dolphins (25%) was similar to that of the western Atlantic population. Porpoises that died from disease or parasitic infection had higher concentrations of persistent organic pollutants (POPs) than animals dying from other causes. Few of the common dolphins sampled had died from disease or parasitic infection. POP profiles in common dolphin blubber were related to individual feeding history while those in porpoises were more strongly related to condition.

“…Again, this will reflect diet: for example, species that feed primarily on cephalopods may be expected to accumulate higher levels of cadmium than those feeding on fish (Bustamante et al, 1998;Lahaye et al, 2005). Another element of interest is zinc (Zn), which plays an important role in mammalian immune systems.…”

Trace elements were analyzed in fish of commercial interest to determine their importance in marine systems of the Western Indian Ocean and their bioaccumulation patterns. The results are equivalent or lower than levels reported in ichthyofauna worldwide. Certain values of muscular Cd, Hg, Pb and Zn were however above thresholds for human consumption. Levels varied among tissues, species and with fish length, but were seldom influenced by the nutritional condition of the fish, its gender and its reproductive status. Correlations between hepatic Hg and Se levels in Swordfish (r 2 = 0.747) and Yellowfin Tunas (r 2 = 0.226), and among metallothionein linking metals imply the existence of detoxification processes in these species. Differences in levels between fish from the Mozambique Channel and Reunion Island probably reflect differences of diets rather than differences of elemental availability in both environments.Capsule : Metal bioaccumulation was quantified in four species of pelagic fish.

“…Although a number of physiological and environmental factors may also have some influence, the feeding behavior (based on fish and cephalopods rich in trace elements) and the complexity of the marine food chain are the major factors responsible for the bioaccumulation of trace elements in long-lived marine animals. 3,25,45,47 …”

Neste estudo avaliou-se a influência de alguns parâmetros ecológicos e biológicos sobre a acumulação dos elementos-traço (As, Cd, Cu, Pb, Se e Ag) no fígado de três espécies de cetáceos, sendo duas de hábito costeiro (Pontoporia blainvillei e Sotalia guianensis) e uma de hábito oceânico (Stenella frontalis), que foram acidentalmente capturados na costa norte do estado do Rio de Janeiro. Diferenças inter-espécies foram observadas no padrão de acumulação dos elementos-traço, Cd e Pb (5,12 ± 0,74 µg g -1 e 21,25 ± 1,35 µg g -1 , respectivamente). Entretanto, as três espécies de cetáceo, S. guianensis, P. blainvillei e S. frontalis apresentaram concentrações hepáticas de As, Cu e Ag similares. O sexo dos indivíduos não influiu na bioacumulação dos elementos. O comprimento total influenciou na acumulação dos elementos-traço no fígado de acordo com a espécie de cetáceo. S. guianensis, que co-habita o mesmo ambiente que a espécie P. blainvillei, apresentou uma diferença significativa na concentração hepática de selênio (20,70 ± 32,22 µg g -1 e 3,24 ± 2,02 µg g -1 , respectivamente). A partir dessas observações pode-se concluir que condições ambientais e parâmetros biológicos, tais como comprimento total e principalmente a preferência alimentar, influenciaram significativamente a acumulação de elementos traço no fígado dessas espécies de cetáceos.The present work tested whether ecological and biological parameters have an influence on the accumulation of trace elements (As, Cd, Cu, Pb, Se and Ag) by the liver of three cetaceans species: two species of coastal habit (Pontoporia blainvillei and Sotalia guianensis) and one of oceanic habit (Stenella frontalis), that were incidentally caught in fishing nets along the north of Rio de Janeiro coast. Inter-species difference was observed on the accumulation of Cd and Pb (5.12 ± 0.74 µg g -1 and 21.25 ± 1.35 µg g -1 , respectively). However, the three cetacean species, S. guianensis, P. blainvillei and S. frontalis presented similar hepatic concentrations of As, Cu and Ag. No gender differences were found on the bioaccumulation of trace elements. Hepatic trace element accumulation was influenced by body length, according to the cetacean species. S. guianensis, which co-habits the same coastal marine environment that P. blainvillei species, presented a significant difference between hepatic selenium concentration (20.70 ± 32.22 µg g -1 and 3.24 ± 2.02 µg g -1 , respectively). Based on these results, it is possible to conclude that, not only the different environmental conditions, but also total length and mainly the feeding habit influenced the accumulation of trace elements by the liver of these cetacean species.
