文摘
The technogenic soil containing Pb and Zn impurities at the Rodna mine (Bistrita-Nsud county, Romania) was submitted to a bioremediation technology. In the 1987(1988)–1996 period, 16 plots and 8 controls were systematically sampled for determination of the enzymatic and bacterial indicators of spoil quality. The evolution of the enzymatic and bacterial potential showed that the best results were obtained with complex treatment (covering with soil+NPK fertilization and sowing a grass-legume mixture or seeds of plants belonging to the native flora of the region). A favourable outcome of the complex treatments is reflected in a gradual colonisation by nematodes and their increased specifical and trophical diversity.
