Congratulations to Heather Vanderlip, who recently defended her thesis titled, “Trends of halogenated flame retardants in herring gull eggs across Canada from 2008–2019.” Using data from Environment and Climate Change Canada, Heather investigated trends of three halogenated flame retardants in herring gull eggs between 2008 and 2019. Despite international regulation on these chemicals, there was little evidence for changes in their concentrations in herring gull eggs during this period. This is likely due to the persistent nature of these chemicals and warrants future research to determine when changes in concentrations may be seen following international regulations.
