Abstract
A field experiment was performed in four freshwater systems to assess the effects of Ni on the benthic macroinvertebrate communities Sediments were collected from the sites (in Belgium Germany and Italy) spiked with Ni and returned to the respective field sites The colonization process of the benthic communities was monitored during a nine month period Nickel effect on the benthos was also assessed in the context of equilibrium partitioning model based on acid volatile sulfides (AVS) and simultaneously extracted metals (SEM) Benthic communities were not affected at (SEM AVS) <= 0 4 mu mol/g, (SEM AVS)/fraction of organic carbon (f(OC)) < 21 mu mol/g organic carbon (OC) Sediments with (SEM AVS) > 2 mu mol/g, (SEM AVS)/f(OC) > 700 mu mol/g OC resulted in clear adverse effects Uncertainty about the presence and absence of Ni toxicity occurred at (SEM AVS) and (SEM AVS)/f(OC) between 04 to 2 mu mol/g and 21 to 700 mu mol/g OC respectively The results of our study also indicate that when applying the SEM AVS concept for predicting metal toxicity in the field study stressors other than sediment characteristics (e g sorption capacity) such as environmental disturbances, should be considered and the results should be carefully interpreted.
