Abstract: The paper presents a comparative bioaccumulation study between the growth of chamomile (Matricaria Chamomilla L.) exposed to toxic metals (Cd, Ni and Pb) and the growth of same plant species unexposed to metals. The soil was contaminated within three independent experiments with Cd, Ni and Pb at the intervention threshold value for sensitive use. Each of the toxic metal was added by watering the seeds, and subsequently the germinated plants. The experiments targeted the effects of soil pollution on the growth of chamomile during three months period. The results showed that in the first month of the study, all three metals accumulated in plants. After the seeds germination and plant growth, high Cd concentration in chamomile plants was detected. Moreover, Ni and Pb were detected in soil in the percentage of 96%. Overall, it was observed that chamomile plants were Cd accumulators at the tested concentrations of 6 mg/kg with no phytotoxic effects. Matricaria Chamomilla L. could be used in phytoremediation of polluted soils, with limitations of use for human consumption, except for the extracts.
