摘要: Mining, milling and smelting operations are major causes of heavy metal contamination constitute an increasing threat to the environment. The objective this work was investigate relationships between soil pollution, humus development microarthropod community structure, using a Biological Soil Quality (QBS-ar) method. Humus samples (0-30cm) were collected during spring 2011 from abandoned mixed sulphides mining area in Northeast Italy, under both forest grassland ecosystems. mine site is contaminated by several metals (Cd, Cr, Cu, Pb, Zn Fe). forms varied Dysmoder Amphimus more developed Oligomull. QBS-ar values presented wide range (between 65 162). Moreover, results demonstrate that ecosystem communities showed high biodiversity (richness). On other hand, we observed stable structures (evenness) sites. do not have significant correlation with classes biological quality. Anthropogenic activities influenced community, altering quantity quality litter chemical-physical structure microhabitats. Preliminary data obtained study suggest application index could be useful tool for monitoring surface soils.
