Abstract
The aim of this study was to survey levels of polychlorinated biphenyls (PCBs), polychlorinated
dibenzofurans (PCDFs), and polychlorinated dibenzo-p-dioxins (PCDDs) in white mullet (Mugil curema),
common snook (Centropomus undecimalis), and acoupa weakfish (Cynoscion acoupa), collected at Sepetiba
bay, Rio de Janeiro, Brazil, March-August 2013. PCBs and PCDD/Fs were determined by High Resolution Gas
Chromatography/High Resolution Mass Spectrometry (HRGC/HRMS) as stated by the US EPA 1613B, 1668B,
and 8290A methods. The concentration of total PCBs ranged from 0.589688 ~ 0.6981629 pg-WHO-TEQ/g ww
and PCDDs/PCDFs ranged from 0.134037 ~ 0.242573 pg-WHO-TEQ/g ww. The concentrations of these
contaminants on fish species currently appear to fall below critical values, and the dietary consumption of these
species did not represent a risk for human health. However, seeking to avoid future problems, systematic
monitoring can prevent complications to the environment, marine wildlife and public health impacts.
