Description

The environmental risk posed by any new chemical produced or used in substantial quantities in the EU had to be assessed. This process involved estimating the concentration of the substance that could be present in water without harming aquatic life. For fresh water, it was usually based on laboratory data showing the effects of the chemical on freshwater organisms. For the marine (saltwater) environment there was often a shortage of data. This project investigated whether freshwater data could be used to predict effects in marine environments, and if so, whether this was possible for all chemicals. Data on the sensitivity of freshwater and marine organisms to the same chemicals were compared. The scope for computerised modelling was examined. In collaboration with regulatory authorities, researchers reviewed whether new toxicity test guidelines were helpful in estimating a product’s hazard to marine organisms.
