Hazardous substance risks:
EU project aims to improve forecasting

The structure of a molecule determines how persistent and mobile a substance in the environment is. Scientists working on EU project zeroPM want to make use of this fact. They are doing this by assigning structures to the substances listed in chemical directories around the world. This work enables them to better predict the hazards posed by substances and mixtures in the future.

Drawing on a Wealth of Data

In their research, the scientists, under the Norwegian Geotechnical Institute (NGI), are drawing on data from 25 chemical directories that contain around 500,000 entries. With the help of special software, they have now identified more than 400,000 structures.

A Foundation Exists

However, there is still a fly in the ointment. Evaluation is more difficult because the data in the directories do not have the same format, and not all molecular structures are available in the quality required for an assessment. Nevertheless, the ZeroPM database offers toxicologists new perspectives for identifying persistent and mobile hazardous substances and for better assessing the risks posed by such substances.
