Emerging persistent chemicals in human biomonitoring for populations in the Arctic: A Canadian perspective
2020
Gibson, Jennifer C.
The future of human biomonitoring in the Arctic will be influenced by the presence of emerging persistent chemicals. Many modelling studies have attempted to predict which contaminants will be of concern next in the Arctic based on chemical and physical properties as well as known risk factors from existing Arctic contaminants of concern. An amalgamated list of emerging persistent chemicals identified through predictive modelling cross referenced with Arctic wildlife monitoring results provides a basis upon which to prioritize future human biomonitoring in the Arctic. Persistent chemicals identified by this analysis are those in common across models (i.e., HCCPD, PCTP, 1,3,5-triBB, 1,2,4,5-tetrachlorobenzene, hexaBDE, pentabromochlorocyclohexane) and those both identified by models and found in Artic biota (e.g., PFNA, PFUnDA, PFDA, PFTrDA, HCBD, HBCDD, PCA, PFDoDA, BTBPE, PCNB, Endosulfan, etc.). Tracking the appearance of new chemicals in environmental monitoring will allow human biomonitoring to keep pace with emerging issues.
