Mining, milling and smelting operations are major causes of heavy metal contamination and constitute an increasing threat to the environment. The objective of this work was to investigate the relationships between soil metal pollution, humus development and microarthropod community structure, using a Biological Soil Quality (QBS-ar) method. Humus and soil samples (0-30cm) were collected during spring 2011 from an abandoned mixed sulphides mining area in Northeast Italy, under both forest and grassland ecosystems. The mine...
