HEAVY METALS IN SOILS AND PLANTS DURING TECHNOGENIC CONDITIONS

The modern data on concentration levels and distribution of heavy metals in ecosystems under technogenic press are discussed. The main ways of heavy metals entering into environment, their migration and accumulation features are also described including the comparative data on heavy metals accumulation both with soils and plants. The modern principles of ecological norming are showed.
