FERREIRA, Aldo Pacheco. Estimation of heavy metals in little blue heron (Egretta caerulea) collected from sepetiba bay, rio de janeiro, brazil. Braz. j. oceanogr. [online]. 2010, vol.58, n.4, pp.269-274. ISSN 1982-436X.  http://dx.doi.org/10.1590/S1679-87592010000400002.

Samples of liver and kidney of Little Blue Heron (Egretta caerulea) collected on Sepetiba Bay, Rio de Janeiro, Brazil, were analysed for their copper, zinc, cadmium, lead, chromium and nickel content. Mean concentration levels in liver and kidney (μg.g-1 dry weight) were 6.32955 and 6.57136 (Cd); 78.17409 and 96.89409 (Zn); 44.01727 and 65.20864 (Cu); 41.15091 and 39.62318 (Pb); 2.80091 and 4.16455 (Cr); and 9.27182 and 9.91091 (Ni), respectively. Results indicate relatively high trace metal contamination in E. caerulea, showing potential widespread biological and mutagenic adverse effects at trophic levels, and therefore, signalling risk to human health.
