Invertebrate and microbial communities in contaminated river sediments
The river sediments of Ardières and Tillet are both polluted with complex substance mixtures. The effect of the contamination with PCB on the oligochaete communities was clearly visible. The effect of the contamination on microbial communities was harder to assess because microbes are influenced by a multitude of environmental factors.
