Long Range Transport and Back Deposition

The Stockholm Convention on Persistent Organic Pollutants (POPs) was established to ensure that governments work together to protect the environment from POPs that travel over long distances. Below is an overview of recent studies on POPs and Volatile Dimethylsiloxanes (VMS).

This paper explores the applicability to chemicals in modern commerce of the screening assessment for Persistent Organic Pollutants (POPs) in the Stockholm Convention. It includes a case study on D4, with the conclusion that the current framework can lead to a false positive classification, because the four screening criteria (persistence, bioaccumulation, long-range transport, and adverse effects) apply to different environmental media/compartments for D4. The paper concludes that the screening process should rely less on the individual screening criteria and more on the comparison of estimated exposure and the thresholds for effects.
