Voronezh region

 Urbanization and human stress lead to ecosystem transformation and accumulation of ecotoxicants, including heavy metals, in plants. Medicinal plants such as large burdock (Arctium lappa L.) and medicinal dandelion (Taraxacum offi cinale L.) are widely used in medicine, but can accumulate both essential and toxic elements. The purpose of the study was to conduct a comparative analysis of the macro- and microelement composition of the roots of large burdock and medicinal dandelion, growing in the natural ecotope of the Voronezh region.

Voronezh region is one of the most important areas of agriculture and crop production. The purpose of the study was to study the patterns of accumulation of the most dangerous heavy metals in wild medicinal plant raw materials of various ecotopes of the Voronezh region. The accumulation of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic was studied, using an example of 10 types of medicinal plant raw materials, which were produced in 51 ecotopes of the Voronezh region.

The Voronezh region is traditionally the most important area of crop production and farming. The purpose of the study was to study the contamination by heavy metals of medicinal vegetable raw materials of the Voronezh region using the example of grass of the bitter emery collected in urban and agro-ecological systems, which experience various anthropogenic effects. The accumulations of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic were studied, in 51 samples of pooch grass bitter.

The Voronezh region is traditionally the most important area of crop production and agriculture. The purpose of the research was to study the contamination with heavy metals of medicinal plant raw materials of the Voronezh region using the example of the roots of ordinary burdock, prepared in urbo- and agro-ecosystems, which have various anthropogenic effects on themselves. The accumulation of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic in 51 samples of raw materials was studied.
