Abstract: | The Stockholm Convention on persistent organic pollutants (POPs) was adopted in 2001. This year is the 10th anniversary of
the adoption of the Convention. Until now, 22 chemicals or chemical categories have been listed as POPs in the Stockholm Convention.
The POPs Research Center was established in Tsinghua University in the same year when the Convention was adopted. In the last
ten years, much work has been done by Chinese researchers to understand the environmental risk of POPs in China. This article
aims to review the recent research progress of our POPs Research Center and some other Chinese researchers’ studies in addressing
the environmental risk of POPs, including the priority screening and inventory study of POPs, monitoring and modeling of POPs
pollution and exposure, and environmental risk assessment and modeling of POPs. Although great advances in addressing the
environmental risk of POPs have been made in recent years, we are still facing quite a few problems, such as data scarcity
and uncertainty in environmental risk assessment of POPs. The study on the effect of POPs mixtures is in its infancy and currently
POPs are usually assessed from legal perspective by risk assessment of single chemicals. These problems should be well addressed
by further efforts. Further studies should also be taken in future to study environment risk of POPs by considering aspects
of coupled dynamics between climate processes and POPs. Such sound scientific, riskbased information can support decision-making
aiming to effectively minimize the risk level of POPs. |
