ABSTRACT:
In the paper results of long-term studies on acidification of water precipitation conducted in seven research points located near Bielsko-Biała were introduced. In each point period of study lasted ca. 1 year. The research was performed in the years 2002-2010. The range of pH of precipitation varied between 3.35 to 7.22. Majority of precipitation samples, because approximately 86% had pH < 5.6 i.e. lower than natural level, which indicated the presence of acidifying substances. Amongst samples of precipitation 47.6% were significantly and strongly acidic i.e. pH < 4.5. The rainwater with pH < 5.6 was more frequent than in more industrialized part of Silesian voivodship. In the investigated area pH of precipitation is mainly under influence of pollution flowing from west and southern-west and local sources of its emission.
