If used improperly or in an inappropriate manner, they also can present unacceptable risks to human and animal health and to the environment.

PRTR have been established throughout the world to track releases and transfers of potentially harmful chemicals. But most of the PRTR systems were designed without considering comparability, each PRTR has its own requirement of reporting chemicals and sectors. To harmonise globally, OECD reviewed the reporting chemicals and sectors across PRTR systems and produced proposal for harmonised lists of reporting pollutants.

OECD countries have developed PRTR system to track releases and transfers of potentially harmful chemicals. To improve PRTR system, OECD have analysed common elements (pollutants, sectors) in different PRTR systems, mainly focus on institutional arrangement. This serves as a common framework for different PRTR system, and supporting materials for a country that intends to develop or update its PRTR.
