Lessons learned from studies with the freshwater mussel Dreissena polymorpha exposed to platinum, palladium and rhodium.

摘要: The platinum group elements (PGE) platinum, palladium and rhodium gain increasing (eco-)toxicological interest due to their cumulative introduction into ecosystems. So far, most PGE exposure studies investigating biological availability, uptake bioaccumulation of as well effects on different toxicological endpoints were performed under non-standardized conditions which occasionally make an interpretation comparison the results difficult. Here we compare with zebra mussels (Dreissena polymorpha) showing influences source, medium, concentration period test system. Problems associated performance evaluation these identified recommendations needs for future are given. As nominal concentrations often did not reflect real reference has be chosen caution, i.e. versus quantified aqueous concentrations. determination factors can problematic when in medium organism reach steady state even after several weeks exposure. For it would advantageous regularly correlating biomarker responses increase knowledge potential adverse metals, preferably using environmentally relevant scenarios. Many aspects discussed present study transferred other aquatic animals respectively.
