Abstract Cultural practices and control of diseases and insects are widely used for cultivation of Olea europea L. These are considered potential contaminants. Aim of this investigation lies in determination of concentrations of contaminants in several edible olive oils. All test samples were purchased in three consecutive seasons. They were analysed in compliance with standardized international protocols of wet digestion methods. Ion concentrations were determined in three replicates using method of inductively coupled plasma optical emission spectrometry. We have registered a positive correlation between storage time and heavy metals contents. It was particularly high in Iranian brands and varied significantly. Investigation results show that all obtained heavy metals contents in pepper-flavoured olive oil samples were significantly lower than in other samples. Considering the fungi-flavoured samples, levels of Pb and Cd were prominent and exceeded the maximum permissible level set in the majority of cases. The further monitoring is needed as all these metals are toxic and their detrimental effect becomes obvious only after several years of exposure.

Abstract Medicinal plants possess several metals obtained naturally or through pollution. The study evaluates the genotoxic potentials and the presence of essential elements and toxic heavy metals in Sesbania sesban var. bicolor (leaves), Cyperus compressus (roots) and Asparagus racemosus (roots), which are used as anthelmintics in the traditional medicine of the Santhals in India. Genotoxicity study was performed as per Organization for Economic Co-operation and Development (OECD) guidelines in rats. Element contents were evaluated using inductively coupled plasma-optical emission spectrometry (ICP-OES). Administration of S. sesban var. bicolor (400 mg/kg), C. compressus (700 mg/kg) and A. racemosus (500 mg/kg) did not cause any abnormalities in the chromosomes. Elemental analysis revealed the presence of lead (5.00 ± 0.05, 4.98 ± 0.01, 4.99 ± 0.07 ppm), cadmium (4.99 ± 0.04, 4.90 ± 0.03, 5.00 ± 0.08 ppm) and arsenic (0.98 ± 0.03, 0.41 ± 0.05, 0.92 ± 0.03 ppm), respectively. Although genotoxic potentials were lacking, the presence of toxic heavy metals in them is a cause of concern.
