This research aims to refine and update the study on the pressure on aquatic life. Firstly, the most

recent toxicity data will be processed in the calculation of the indicator. These data are mainly based on the new European recognitions. Secondly, it will include the application mode of the pesticides. This should increase the relevance of occurrence of pesticides and their pressure on the aquatic life. Thirdly, the study will reconsider the distribution of the quantities sold on agriculture and non-agriculture and in the agriculture within the different crops. This should allow a better assessment of the different players in the pressure on aquatic life.
