Abstract
The residues of pharmaceuticals in the ecosystem are in the centre of the ecological interest because many of these substances seem to be harmful at long-time, low-level exposition to higher organisms. These substances contaminate municipal wastewaters and subsequently surface waters.
Attractive and economically favorable method for the removal of these substannces is phytoextraction by root systems of plants. The phytoextraction experiments using in vitro cultures of plants (e.g.
Zea mays, Helianthus annuus, Linum usitatisimum, Brassica napus and Pisum sativum) were carried out with common painkillers (ibuprofen, diclofenac, and naproxene). The results showed good ability of used plants for extraction.
These substances are in plants partly metabolized and 10 - 20 % of the parent compound can be obtained as extractable metabolite.
