摘要: This study investigates the air deposition of heavy metals (past and recent) in Poland using a common bioindicator – moss Pleurozium schreberi. In 2010 samples were collected from 320 sites evenly distributed throughout country; 297 coincided with those which 1995 survey was carried out. green parts mosses, concentrations Cd, Cu, Fe, Pb, Zn determined. The data compared 1995. concentration most studied decreased significantly (P<0.05) between surveyed years: 0.45 to 0.30 mg Cd·kg -1 , 7.6 6.0 Cu·kg 362 344 Fe·kg 18.8 4.9 Pb·kg taking into account median values. temporal trend dependent on region (for some provinces decreases insignificant). did not alter time; values this variable 42.8 47.5 mg·kg 2010, respectively. spatial patterns metal mosses similar both surveys; southern Poland, industrialized densely populated, contaminated more than rest country.
