The study of the chemical composition of precipitation was carried out from November 2002 till October 2003, in the urbanized area of the Gulf of Gdańsk. About 88% of the collected samples showed acid value, and the average pH was 5.14. The highest acid values were found in summer when sulfates were the dominant ions. The highest concentrations of nitrates were noted between autumn and spring, and the precipitation pH was less acidic than in summer. The coastal station at the Gulf of Gdańsk was characterized by more effective neutralization of precipitation in the heating season as compared to the other urbanized areas. It was found that the neutralization process in the coastal zone was much more intense due to the sea salt particle presence in aerosols rather than in gaseous ammonia. The most intensive neutralization of precipitation was observed between late autumn and spring. In May, when offshore winds dominated, the values of neutralization coefficient (NF) for Na+ and NH_4+ were 1.3 and 0.2, respectively. It was evidenced that the specific combination of meteorological parameters (velocity and direction of wind, humidity and temperature of air) had a significant influence on the chemical composition of precipitation.
