Abstract
  • Release of pharmaceuticals in the environment has been emerging as a great concern for ecosystem and human health. Ibuprofen (IBU) represents one of the most widespread pharmaceuticals in surface waters and sediments in spite of the high removal rates occurring in conventional wastewater technologies. To assess the potentiality of phytoremediation in assisting these technologies, the screening of plant species for tolerance and removal ability of pollutants is a very important issue. In this study, the effects of different IBU concentrations on callus cultures of Populus nigra L., a pioneer tree species in the riparian ecosystem, were investigated. Results evidenced a notable tolerance of poplar cells to IBU, especially at high concentrations (IBU 30 mg L-1), which even stimulated growth. At this concentration, the ability to withstand IBU was accompanied by inhibition of lipoxygenase (LOX) activity, reduction of lipid peroxide content and increase of membrane redox activity. Irrespective of initial IBU concentrations, a complete removal of this compound from the growth medium by poplar cells during a subculture occurred. Antioxidative enzyme activities and polyamine content were stimulated by IBU 0.03 mg L-1, while no effect was found in cells exposed to IBU 30 mg L-1, except for a decrease of guaiacol peroxidase (GPX) activity. These findings put in evidence a notable potential of this plant species for the phytoremediation of IBU-contaminated substrates. (literal)
