The problem in the provision of Russian medicine with high-quality medicinal plant raw materials is most pressing in higher anthropogenically loaded regions that also include the Voronezh Region situated in Central Russia. The environmental impact on the content of heavy metals, pesticides, and radionuclides was studied using knotweed (Polygonum aviculare) herb and great plantain (Plantago major) leaves as an example. The investigation revealed an increasing trend for the study areas and medicinal plants growing there to be anthropogenically polluted with heavy metals. The content of organochlorine pesticides and the activity of radionuclides (cesium-137 and strontium-90) were not higher than the maximum allowable levels in the samples of the raw materials, suggesting the favorable environments of the study Voronezh areas and suburbs in terms of these indicators.
