Model to Predict Concentrations of Chemicals in Marine Aquaculture Sediment-Collection of EU Environmental Data for Exposure Scenarios of Freshwater Sediments from Small Edge-of-field Water Bodies EFSA/2023/OP/0003

The aim of this procurement is to conclude on a framework contract (lot 1) and a direct contract (lot 2):

- lot 1 - develop, calibrate, validate and ground truth a model to predict environmental concentration of chemical substances in marine sediments under sea cages when those have been administered via feed;

- lot 2 - collection of existing and generation of new environmental data relevant for the characterization of aquatic sediment scenarios to estimate the exposure of pesticides in small water bodies adjacent to agricultural fields.
