Testing of Phytotoxicity of Mining Waste to Determine the Direction of Future Development

Popis výsledku v původním jazyce

Energy industry and coal mining produce large amounts of mining waste. The material is accumulated on dumps and heaps which alter the landscape appearance. As the material is waste from mining, there are concerns from possible environmental contamination. On the other hand, some scientific publications mention favorable properties of this material and claim that it can be possibly used for example in land reclamation. This research is focused on the testing of phytotoxicity of samples collected from mining waste heaps. The pH values of tested samples ranged from 7.00 to 8.67. In the phytotoxicity tests, vital seeds of plants Sinapis alba. L., Hordeum vulgare L., and Cannabis sativa L. were used. The tests did not exhibit high phytotoxicity. Contrariwise, many results showed a high rate of growth stimulation (nearly 80%). Average values (median) of growth inhibition observed in individual samples for all three plant species in the share of 100% (with no addition of OECD soil) ranged from MINUS SIGN 13.96% to MINUS SIGN 33.73%. The obtained results can confirm the positive properties of mining waste in terms of phytotoxicity, resp. the experiments did not confirm the phytotoxic effects on the tested plants. Mining waste/material could have a positive effect on plants and thanks to its properties it could be used e.g., in land reclamation.
