Non-polluted Sphagnum fallax moss was transplanted from Augustdw region and used as bioindlcator for studying the air pollution with Cr, Pb and Zn in the vicinity of Warsaw steel mill in 1993-2008. The moss samples were washed with distd. H2O and exposed to atm. air for 12 weeks, mineralized in muffle furnace, dissolved in 30% HCI soln. and analyzed for the heavy metals by at. absorption spectrometry. The max. Cr, Pb and Zn contents in the moss in 1993 were 10.6, 35.9 and 145.0 mg/kg, resp., and decreased down to 4.8, 22.7 and 110.0 mg/kg, resp., in 2008. The steel mill remained, however, a "hot spot" in the Warsaw area. Source

Pleurosium schreberi moss from the heavy metals-polluted Olkusz region (i) and Sphagnum fallax moss transplanted from non-polluted Augustdw region and exposed in bags for 12 weeks during summer time in the Olkusz region (ii) were dry mineralized in a muffle furnace, dissolved in 30% HCI soln. and analyzed for Pd, Cd, Zn, Cu, Fe, Cr, Ni and AS contents by at. absorption spectrometry. The metal contents in (i) and (ii) were correlated to show the extent of air pollution with the metals. In the polluted region, the air pollution with Pb was 350 times, with As 184 times, with Cd 74 times, and with Zn 47 times higher than in the non-polluted area. The picture of air pollution with Pb, Cd, Zn and As was on the immission maps similar in both cases according to both methods as verified by statistical anal. Source
