INTENSITY OF HEAVY METAL AND ARSENIC ACCUMULATION IN MEDICINAL PLANTS OF SYNANTHROPIC FLORA IN VORONEZH REGION

The aim of this study is to examine the peculiarities accumulation most dangerous heavy metals and arsenic in medicinal plant raw material synanthropic flora Voronezh region.
 Materials Methods. was carried out by atomic absorption spectrometry. author studied (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) 10 types materials harvested 51 locations (Voronezh region), which differ terms anthropogenic impact.
 Results. highest level lead consentration noted Taraxacum officinale F.H. Wigg, Arctium lappa L. roots, Рolygonum aviculare Plantago major leaves. Mercury concentration all samples rather low. A bit higher mercury L Urtica dioica leaves, Artemisia absinthium High cadmium found Wigg Leonurus quinquelobatus Gilib. Arsenic accumulated intensively Achillea millefolium Nickel Zinc mainly roots herbs themselves. Having analyzed coefficients for materials, we organized decreasing order: zinc > copper cobalt nickel chromium mercury.
