title: Quality of roof runoff waters from an urban region (Gdańsk, Poland).
abstract: The paper presents the results of testing of roof runoff waters from buildings in the city of Gdańsk (Poland), carried out as a part of a broader research project aimed at the determination of pollutant levels in precipitation. The analytes determined included volatile organohalogen compounds, petroleum hydrocarbons, Na+, K+, NH4+, Mg2+, Ca2+, F-, Cl-, NO2-, NO3-, PO4(3-), SO4(2-) ions, as well as organonitrogen, organophosphorus and organochlorine pesticides. In addition, the toxicity and pH of the samples were examined. The samples were collected over a period of six months, during or immediately following precipitation events. More than half of the samples (25) were found to be toxic, with inhibition exceeding 20%. The toxicity was weakly correlated to the levels of organonitrogen and organophosphorus pesticides in runoff waters. It was established that at least in some cases the roofing material affected the levels of the pollutants found in the samples.
