Heavy Metals, PFAS, Cyanotoxins in Maine Lakes – Risk assessment approaches to Toxic Substances

Presented by Breana Bennett
This presentation will discuss how Maine CDC determines how much is too much chemical contamination in fish tissue and how that is considered in deriving fish consumption advisories. This will be discussed in the context of the statewide fish consumption advisory for methylmercury and the emerging PFAS contaminants. The presentation will also discuss the challenges in developing advisories for harmful algal blooms.
