Acid pollutants in air and precipitaion/deposition at the Sudeten Mountains,Poland

The results of several separately performed field studies on air quality in south-western Poland (Black Triangle) are presented In the period 1988–1993 atmospheric aerosol measurement and precipitation/deposition samples were collected at three locations of mountain region (810–1490 m asl). Precipitation was monitored in forest ecosystem using a 24-gauge network was carried out during June–October 1992 and 1993. The occurence of cloud at ground level over hills is difficult to categorize and quantify in mountain terrain and has constituted a basic part of our studies. Precipitation/deposition samples (seven rain and three cloud collectors) in the Karkonosze Mountains were collected over the period 1994–1995 (four field campaigns were conducted) to examine aqueous chemical interactions between constituents in samples. Meteorological data measured at the site included temperature, humidity, wind speed and direction and the amount of precipitation.
