Importance of Internal Biotic Concentrations in Risk Evaluations with Aquatic Systems

摘要

Ecological risk evaluations are commonly performed using aqueous concentrations and aqueous toxicity mea- surements as a starting point. However, risk evaluations could be carried out using internal biotic concentrations and the internal lethal or sublethal concentrations. This has several advantages. Firstly, the internal lethal and sublethal concentrations are relatively consistent in groups of chemicals having a similar mode of action.
