Ecotoxicological joint effects of mixtures – relevance and appropriate consideration in the environmental risk assessment of plant protection products and biocides

The aim of this project was to assess the relevance of joint effects related to plant protection products and biocidal products. Based on a general analysis of the concepts of mixture toxicity and their application, as well as a detailed analysis of the current environmental risk assessment schemes and their limitations, options were developed for the consideration of joint effects of pesticidal mixtures in the regulatory risk assessment. In a final step, consequences of implementing such options into the regulatory decision scheme were analysed.

The final report of this project is available [for more information see Part 1 and Part 2].
