%X Samples of liver and kidney of Kelp gull (Larus dominicanus) collected on Sepetiba Bay, Rio de Janeiro, Brazil, were analysed for their copper, zinc, cadmium, lead, chromium and nickel content. All the analyses were made using the inductively coupled plasma optical spectrometry method (ICP-OES). The investigation focused on the variability of the elements content in kidney and liver from a number of sampling seabirds and over different seasons. The results were interpreted using the analysis of variance test (ANOVA). This has revealed differences in concentration for the majority of elements with regard to organs, and how different sampling metals and organs are related to each other. Results indicate relatively high trace etalcontamination in L. dominicanus, showing potential power of idespread biological and mutagenic adverse effects in trophic levels, and herefore, signalling risk to human health.
