Expert Panels

Expert panel services for reviews of mercury studies.In 2006, Mr. Harris was a plenary speaker and panel member at the 8th International Conference on Mercury as a Global Pollutant in Madison, Wisconsin, USA , addressing the relationship between mercury loading and fish mercury concentrations.   The panel produced a publication on the recovery of mercury-contaminated fisheries, in the Swedish journal Ambio (Munthe et al., 2007).  These global conferences every 2-3 years are major events for scientists and managers seeking to present and see the latest research regarding mercury cycling in the environment and related health issues.    Mr. Harris is a member of the steering committee for the 10th International Conference on Mercury as a Global Pollutant in Halifax, Nova Scotia in 2011.
