ABSTRACT
Our paper presents the results of determination of road runoff water pollutants. Samples of runoff waters were collected at six sites with high traffic intensity located along a major transportation route from the city of Reda to the city of Gdańsk, and at one site with low traffic intensity located in Reda. Sampling was carried out over a period of two months in the fall of 2000. Additional samples were collected in March 2001. The analytes determined in the samples included organochlorine, organonitrogen and organophosphorus pesticides, selected volatile organohalogen compounds, petroleum hydrocarbons, as well as selected anions and cations. Total organic carbon (TOC) was also determined. In the petroleum hydrocarbons group, the highest concentrations were recorded for methyl tert-butyl ether (MTBE). Heptachlor epoxide and o, p'-DDE (DDT metabolite) were detected most often among the pesticides. Sulphate ions were found in all samples. Very high concentrations of sodium and chloride ions were measured in samples collected directly before the winter season. Overall, the results confirmed that road runoff waters are heavily polluted and their quality should be monitored.
