TR 134 – Sufficiency of aquatic hazard data for environmental risk assessment in sediment and soil

In a nutshell

A study by ECETOC has investigated the use of data from ecotoxicity tests carried out in water to assess toxicity in soils and sediments. Until now, there has been no clear consensus about the extent to which aquatic toxicity data are sufficient for managing safety in other compartments.

Overall, the study found that the dataset used limited the ability to draw concrete conclusions. However, the findings do not contradict previous studies demonstrating that the use of aquatic data to assess toxicity in soil/sediment compartments is fit for purpose, and the ECETOC Task Force made a number of suggestions for further work in this area.
