cadmium

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 search for new technologies for the purification of natural and waste water does not lose its relevance. Biologically, heavy metals are among the most dangerous pollutants. The highest toxicity among them has cadmium, causing serious environmental problems during technogenic pollution of the aquatic environment, and its extraction is an urgent task. The analysis of foreign studies on the extraction of cadmium ions is carried out.

To study the resistance of isolated rhizobacterium Bacillus sp. 14 to cadmium (II), bioaccumulation of the metal by this microorganism was investigated. It was shown that accumulation of cadmium (II) occurs during the exponential phase of the microorganism’s growth. The predominant role of the extracellular surface of the growing cells Bacillus sp. 14 in the cadmium (II) resistance was clarified.

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.
