Contemporary lead concentration and stable lead isotope ratio distribution in forest moss across the Czech Republic
Popis výsledku v původním jazyce
Lead concentrations and stable lead isotopes (Pb-204, Pb-206, Pb-207, Pb-208) were measured in forest moss samples (Pleurozium schreberi or Scleropodium purum) collected at 273 sites across the Czech Republic during 2010. Continuously decreasing median Pb concentrations in moss were documented over the last two decades: 1995: 11 mg/kg, 2000: 5.66 mg/kg, 2005: 4.94 mg/kg and 2010: 2.85 mg/kg. Several local anomalies have decreased in scale, the overall regional distribution patterns remained, however, the same. The regional Pb isotope ratio distributions show that the ratios show little variation for a large central part of the country and provide the large-scale background isotope ratios for the Czech Republic of about Pb-204/Pb-206 = 0.0550, Pb-206/Pb-207 = 1.167, Pb-206/Pb-208 = 0.478 and Pb-207/Pb-208 = 0.409 for 2010. This background Pb isotope ratio signal in moss has been locally (900-7500 km(2)) modified by specific Pb isotopic ratio signals caused by deposition of Pb emissions
