“…In the literature, it is described that age does not affect the concentration of mercury in feathers of adult birds and an increase [Hg] in relation to chicks is indicated (Furness et al, 1995;Stewart et al, 1997). The hypothesis presented in the work of Thompson and Furness (1989) and Kim et al, (1996) which suggests that the ability of demethylation of organic mercury in the liver of birds depends on their age may explain the results. Chicks and juveniles penguins through demethylation may protect their body against methylmercury accumulated in the liver more effectively than adults.…”

Abstract. Birds due to its position in the trophic chain are good monitors of the marine environment in terms of mercury contamination. For the proper interpretation of results it is necessary to know both the processes of accumulation of this metal in their bodies and processes of elimination. Research involving the Penguin (Spheniscus demersus) living in a ZOO has identified the relationship between diet and the amount of mercury removed from the penguin body in guano, feathers, and in the case of females with eggs. The research was conducted in years 2009-2011. Total mercury was determined in elements responsible for detoxification and in the diet of penguins. Mercury concentration was determined by atomic absorption spectrophotometry with AMA-254 automatic mercury analyzer. The highest average mercury concentrations were determined in feathers: 1781.12 ngHg

“…The Hg level obtained in this study was also lower than those in birds from the Siberian Sea (4.01 mg/kg dw) (Kim et al, 1996) or the Barents Sea (11.1 mg/kg dw) (Savinov et al, 2003). On one hand, this probably resulted from the fact that gulls were residing in areas far from the Baltic Sea, where exploitation of Hgcontaminated fish was lower (Elmgren, 2001).…”

“…Significant copper levels correlation with body mass may reflect that these shorebirds, when compared with other birds, may use more energy by keeping higher metabolic rates (Colwell, 2010) and ingest higher prey mass. Thus, copper level being correlated with body mass may have arisen from bioaccumulation via species-specific metabolism and it is thought to be unlikely reflect pollution or higher natural background level of copper in their habitats (Kim et al, 1996). …”

Cadmium, cobalt, chromium, copper, manganese, nickel, zinc and lead concentrations were detected in feathers of Buff-breasted Sandpipers (Calidris subruficollis) captured during the non-breeding season and analyzed with relationship to body mass. Of these metals tested for, only copper levels (2.28 µg/g) were positively correlated with bird body mass. Zinc levels showed higher concentration (67.97 µg/g) than the other metals, and cadmium levels showed the lowest concentration (0.14 µg/g). Trace element concentrations were below toxicity levels for all tested chemicals and we suggest that this probably reflects that essential elements are maintained there by normal homeostatic mechanism and that no excessive environmental exposure to these elements during migration or on the wintering area is suggested by these results.Keywords: Charadriiformes, contaminants, body mass, wintering area, shorebirds. Concentração de elementos-traço em maçarico-acanelado amostrados noParque Nacional da Lagoa do Peixe, Sul do Brasil ResumoAs concentrações de cádmio, cobalto, cromo, cobre, manganês, níquel, zinco e chumbo foram detectadas em penas de Maçarico-acanelado (Calidris subruficollis) capturados durante o período de invernada e analisados em relação a massa corporal. Destes metais analisados, somente os níveis de cobre (2,28 µg/g) foram correlacionados positivamente com a massa corporal dos indivíduos. Níveis de zinco apresentaram-se mais altos (67,97 µg/g) que outros metais e os níveis de cádmio apresentaram as menores concentrações (0,14 µg/g). As concentrações dos elementos-traços estão abaixo dos níveis de toxicidade em todos os testes químicos e sugerimos que isto provavelmente ocorre pela manutenção dos elementos essenciais através do mecanismo normal de homeostase e não reflete a exposição destes elementos durante a migração ou nas áreas de invernada.Palavras-chave: Charadriiformes, contaminação, massa corporal, área de invernada, aves costeiras.
