Hazard of Contamination with Heavy Metals in Thymus serpyllum L. Herbs from Rural Areas

The aim of the research has been to assay contents Zn, Cu, Mn, Fe, and Pb in soil organs wild Thymus serpyllum L. acquired from three natural habitats Kuyavia-Pomerania Province (Poland) not exposed contamination with metals. As compared geochemical background soils region value enrichment factor (EF), there was noted a considerable content two locations. plant tissues one locations higher than admissible specified by World Health Organization WHO (above 10 mg kg−1 d.w.). for Zn content, only plants relatively youngest phytocenosis met conditions herbs be used phytotherapy. dry weight collected other exceeded 50 kg−1. risk an elevated makes it necessary monitor environment limit collection habitats, as well encourage controlled habitats.
