Lead and zink in permafrost forest-steppe soils

In this work lead and zinc in the soils of permafrost forest-steppe have been studied. It was revealed that binding heavy metals following descending series: Zn > Pb, which corresponds to values their clarks. Studies shown occurs mainly with fulvic acids, -with humic is associated chemical properties. The content Pb rock turned out be lower than soil, possibly due biological accumulation. No signs environmental pollution were found study area. level plants soil not higher established norms. These data can used assess ecological state Each plant has its own metal accumulation threshold determined by characteristics. There are easily absorbed plants. As a result, unevenly distributed roots overground mass, create decreasing chain absorption: comes first, then lead. possible substances play role barrier for lead, so concentration vegetation low.
