Anthropogenic activities result in the increase of number pollutants and their concentrations in
sediments. The purpose of this study was to characterize the polycyclic aromatic hydrocarbon (PAH)
contamination in the sediments of stormwater industrial watershed according to particle size distribution and
organic matter content. Results indicated to advantage of dust fraction at level 82% and organic matter at
4.22%. Concentrations of the sum of PAH analytes in the sediments were significantly higher compared to
that of reference values for threshold and propable effect levels. Isomer ratio analysis suggested that the
predominant source of PAHs were pyrogenic. PAH levels in these contaminated ponds exceeded ten times
those ecological screening values for individual PAH analytes suggesting that they may pose a toxicological
risk to wildlife.
