Hazardous substance risks:
EU project aims to improve forecasting

The structure of a molecule determines how persistent and mobile the substance in question is in the environment. Scientists in the EU project zeroPM want to make use of this fact. They do this by assigning structures to substances that are listed in chemical inventories worldwide. This will enable them to better predict the dangers posed by substances and mixtures in the future.

Drawing from the full

In their investigations, the scientists from the Norwegian Geotechnical Institute (NGI) draw on data from 25 chemical directories with around 500,000 entries. Using special software, they have now identified more than 400,000 structures.

A basis is there

However, one drawback remains. As the data in the directories are not all in the same format, evaluation is made more difficult and the molecular structures are not all available in the required quality. Nevertheless, the ZeroPM database offers toxicologists new perspectives for identifying persistent and mobile hazardous substances and better assessing the risks posed by such substances.
