International Pellet Watch: Observing POPs, identifying the source, and understanding long-term change through citizen volunteer monitoring

Research grant

Project Description

For the purpose of controlling environmental burden and continuously monitoring for persistent organic pollutants (POPs), the areas and sites for monitoring will be expanded, utilizing the networks of individuals, researchers, and citizen groups that have provided cooperation to date. Long-term pellet watch will be carried out to determine the rise and fall of POPs on a global scale. In addition, POPs data will be sourced from sediment and from the atmosphere in “hotspots" where there are high levels of POPs, and will be combined with the results of pellet measurements to predict the source of POPs.
