In 2007 air pollution by heavy metals (Cd, Pb, Cu, Zn, Fe Cr, Ni) and SO2 in the Base Station of Integrated Nature Monitoring System was estimated using lichen Hypogymnia physodes as bioindicator. In July 2007 lichen samples from natural environment were collected in six Base Stations (Puszcza Borecka, Wigry, Storkowo, Pożary, Św.Krzyż, Szymbark). During winter season 2006/2007 and summer season 2007 lichens Hypogymnia physodes were transplanted for six months to three Base Stations (Koniczynka, Św. Krzyż, Szymbark). Different air pollution of the Base Stations were found. The lowest concentrations of the most of analysed heavy metals were found in Storkowo and Wigry Base Station. A high concentration of cadmium and lead, higher than in 2005, were found in lichen collected in Puszcza Borecka. Base Stations located in central and southern part of Poland had higher concentrations of heavy metals mainly cadmium lead and iron than those from the North of the country. In the all Base Stations high concentrations of sulphur were found which confirm air contamination by sulphur dioxide. No statistical differences in metals and sulphur accumulation in transplanted lichens between winter 2006/2007 and summer 2007 seasons were found. It shows no impact of heating season on air contamination in winter 2006/2007.
