Abstract

FERREIRA, Aldo Pacheco. Measurement of chlorinated dioxins, furans and PCBs in Ardea alba Great Egret, and Puffinus puffinus Manx Shearwater: Ilha Grande Bay, Rio de Janeiro, Brazil. RGCI [online]. 2012, vol.12, n.1, pp.7-15. ISSN 1646-8872.

Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) concentrations were measured in seabirds from Rio de Janeiro, Brazil. Species, Great Egret and Manx Shearwater, were collected in 2008-2010 on Ilha Grande bay. Detectable hepatic concentrations of PCDD/Fs and PCBs were found in all samples analyzed. The concentrations were below the range of concern established by WHO. This is the first measurements of PCDD/Fs and PCBs congeners in seabirds from this area, and suggests that future studies should take note of the results in order to test for a greater range of compoundsand species and to determine levels of environmental contamination.

Keywords : Persistent organic pollutant; risk to environment and health; seabird; dioxin; polychlorinated biphenyl ethers.
