Description 
Summary

Data on benthic communities' structure related to environmental parameters (sediment and overlying water conditions). Data also on nutrient sediment-water fluxes. All data concern industrial and domestic contaminated areas and a cleaner reference area. Since 1990 toxicological studies of sample sediments have been conducted.
