Populations of medicinal plants growing on serpentines and their respective soils were analyzed for Fe, Ni, Mn, Cr, Co, Cd, Cu, Zn, and Pb using inductively coupled plasma atomic emission spectrometry. Aqua regia extraction and 0.43 M acetic acid extraction were used for the quantification of pseudototal and bioavailable fractions, respectively, of elements in soil and nitric acid digestion for determination of total element content in plants. Screening was performed to (1) document levels of toxic metals in herbs extensively used in preparation of products and standardized extracts, (2) compare accumulation abilities of ferns and seed plants, and (3) estimate correlations between metal content in plants and their soils. The toxic element content of plants varied from site to site on a large scale. The concentrations of Fe and Ni were elevated while those of Cu, Zn, and Pb were close to average values usually found in plants. The highest concentrations for almost all elements were measured in both Teucrium species. Specific differences in metal accumulation between ferns and seed plants were not recorded. The investigated species are not hyperaccumulators but can accumulate toxic elements, in some cases exceeding permissible levels proposed by the World Health Organization and European Pharmacopoeia. The harvesting of medicinal plants from serpentines could be hazardous to humans.

Abstract:The effect of aluminium and cadmium on growth and physiological parameters in 60 days old basil seedlings (Ocimum basilicum L.) grown in polluted soil were investigated. Control plants, grown in unpolluted soil, were used for evaluation of the heavy metal effect. Growth parameters were analysed immediately after sample collection, leaf area and plant height were recorded. Analysis of secondary metabolite, proline, total carbohydrates content and antioxidant capacity in 60 days old seedlings was performed. The antioxidant activity of basil extracts was determined by the DPPH method, and results showed an increase of antioxidative capacity in basil seedlings exposed to heavy metal stress due to the activation of antioxidative system in plant cells. Maximum production of secondary metabolites was recorded for seedlings exposed to 100 mg/kg soil Cd and Al. Results showed that cadmium stress increased concentration of proline, while aluminium did not had that effect. The content of total carbohydrates remained almost unchanged, with exception of basil seedlings grown on soil containing 50mg/kg AlCl 3 .
