Cím:Effects of heavy metals on seed germination and root length in mining waste - compost mixtures / Attila Nagy
Dátum:2008
Megjegyzések:Using cost effective, environmentally friendly phytoremediation technology, heavy metal contents may be able to be reduced from polluted matrixes. Concerning any phytoremediation technologies, the ecotoxicological and phytotoxicological effects of a polluted material is one of the main point, which should be evaluated in order to get precise basis for choosing the best phytoremediation technology. In this study widely accepted phytotoxicological methods such as seed germination, root growth inhibition were carried out. In many cases the polluted site is not appropriate for revegetation of its own properties because of toxic content of heavy metals, pH, and lack of nutrients. Therefore in this study, the effect of mine tailing was assessed by using composted sewage sludge in different ratios, which can buffer the toxic effects of metals to some extent. Often applied indicator plant species, such as cabbage (Brassica oleracea L. convar. Capitata provar. Alba) and lettuce (Lactuca sativa) were applied to examine the phytotoxicological properties of mine tailing ? compost mixtures. Based on the results of growth inhibition and seed germination test 5 V/V% compost is recommended to use for phytoremediation due to its buffering effect. Enhanced ratios of compost caused phytotoxicity possibly due to its relatively high bioavailable Cu, Zn content, therefore it is not recommended.
