Global cultivation intensity as a proxy for POPs

Strict regulation has reduced the concentration of some POPs. However, new chemical contaminants reaching the Arctic is a matter of great concern. There are around 150,000 chemical substances but less than 1,000 are regularly monitored. This lack of monitoring means we often do not know enough about the effects of these chemicals on ecosystems and humans. This highlights the need to strengthen existing international mechanisms for regulating POPs. These include an improved global approval system for new chemicals.
