Abstract

The paper gives the results of the first studies on the chemistry of cloud water collected during 3 mo (Aug.–Oct. 2010) in the free atmosphere over the area to the south of the Tri-City (Gdansk-Sopot-Gdynia) conurbation on the Gulf of Gdansk, Poland. Taken from cumulus, stratus, and stratocumulus clouds by means of an aircraft-mounted collector, the water samples were analyzed for the following contaminants: anions (chlorides, fluorides, nitrates, sulfates, and phosphates), cations (lithium, sodium, potassium, ammonium, calcium, and magnesium), and trace metals. In addition, pH values were measured, and the type and composition of suspended particulate matter was determined. We discuss the relationship between the concentration of inorganic ions and the type of cloud from which water was sampled. The chemistry is also likely related to the circulation pattern and inflow of clean air masses from the Baltic Sea. Moreover, a relationship was found between the composition of the samples examined and the location of pollutant emission sources.
