Recent research and analysis concluded that people are not at risk as a result of MSMA’s former use for bark beetle control. The arsenic associated with past application is largely confined to the treated trees and is not migrating into the surrounding soil or vegetation.
This independent study was led by Dr. Ken Reimer, Director of the Environmental Sciences Group at the Royal Military College of Canada, and Dr. William Cullen, Professor Emeritus in the Chemistry Department at the University of British Columbia.
Both authors are recognized nationally and internationally as experts in arsenic toxicology. Dr. Reimer’s research interests include new ways of conducting ecological and human health risk assessments, contaminant uptake, and the transformation and mobility of arsenic in the food chain. Dr. Cullen has published extensively on the speciation, transformation and metabolism of arsenic in the environment.
