Abstract

Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) concentrations were determined in three species of edible fish from Sepetiba bay, Rio de Janeiro, Brazil: silver scabbardfish (Lepidopuscaudatus), Whitemouth croaker (Micropogoniasfurnieri), and mullets (Mugilliza), which were collected in July 2012. PCDD/Fs and PCBs were determined by high-resolution mass spectrometer (HRGC/HRMS) according to the US EPA 1613B, 8290A, and US EPA 1668B methods. The concentration of total PCDDs/PCDFs ranged from 0.10105 ~ 0.2141 pg-WHO-TEQ/g ww and PCBs ranged from 0.08834 ~ 0.62304 pg-WHO-TEQ/g ww. Judging from the European Union regulation limit levels of PCDD/PCDFs and PCDD/PCDFs/PCBs were lower than the criteria in all samples. The main objective of the survey was to obtain information about existing levels of pollutants, having as a consequence the possibility of providing preventive actions and assessing risk; but, the results showed the dietary consumption of fish from Sepetiba region, did not represent a risk for human health.
