Assessment of the contamination of an Italian drinking water reservoir by chlorinated micropollutants
Twenty-two sediment samples, taken from lake Simbirizzi, an artificial reservoir, supplying drinking water to the city of Cagliari (Sardinia, Italy), were analyzed for their content of polychlorinated biphenyls (PCB) and of organochlorinated pesticides (OCP). The quantification of micropollutants was performed by analyzing purified sediment extracts through high resolution capillary column gas chromatography-electron capture detector (HRGC-ECD). For each of the quantified contaminants, a spatial distribution map, based on a mathematical interpolation of the concentrations in the sediment samples, was developed. Finally, the water compartment concentrations in the sediment samples, was developed. Finally, the water compartment concentrations of the micropollutants were extrapolated from the sediment concentrations. The results are presented and discussed in this publication.
