Accumulation of heavy metals and arsenic in grass Leonurus quinquelobatum Gilib.

The Voronezh region is traditionally the most important area of crop production and farming. purpose study was to contamination by heavy metals medicinal vegetable raw materials on example grass five-plant desert collected in urban agro-ecological systems, which experience different anthropogenic effects. accumulations (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) arsenic were studied, 51 samples five-layer grass. Comparing data metal content upper soil layers these elements desert, it can be assumed that there are significant physiological barriers accumulation ecotoxicants generative organs plant, particularly noticeable for such as lead, arsenic, cobalt chromium. five-point able selectively concentrate some entering active centers enzyme systems (such copper zinc) if their environmental below vital level; With a soils, plant also physiologically blocked entry into leaves. Thus, under load conditions, an edaphotype formed result action selection conditions man-made pollution external environment manifestation adaptation conditions. results studies have shown accumulate toxic from planning places assessing its quality.
