Abstract

Aim. To investigate the content of heavy metals (HM) in the seeds and roots of Atropa belladonna plants. To identify possible changes in their concentrations over the years of growing these plants. Methods. Field and spectrometric method, methods, common for agriculture, plant growing and statistics. Results. The content of heavy metals (HM) in the seeds and roots of belladonna plants was determined. It was found that plant roots ac- cumulate them much more compared to the seeds. The concentration of such HM as barium, cadmium, copper, iron, manganese, nickel, potassium, sodium, strontium, and zinc in the plants exceeds the maximum permis- sible level, which testifi es to partial soil contamination in the region. Conclusions. As there are no data about maximum permissible ratios for the content of important chemical elements in the raw plant material, specifi ed in normative and regulatory documents, scientists have to launch complex investigations, involving specialists of relevant fi elds to identify the mentioned gradation. It was determined that the main part of HM is accumu- lated in the roots of belladonna plants, whereas their content in the seeds is several times smaller or equals the value under the sensitivity threshold of analytical devices. This fact testifi es to the prospects of growing the mentioned medicinal herb in Kyiv region for further industrial processing. Chemical elements, which belong to compounds of lanthanides and actinides, are almost not accumulated in belladonna plants.
