Canadian, US governments continue focus on chemicals of concern

The governments of Canada and the United States have committed themselves to considering additional chemicals of mutual concern (CMC) in a 2017-19 priority action plan. The agreement comes under the CMC annex of the 2012 Great Lakes Water Quality Agreement. This outlines the countries’ commitments to protecting human health and the environment “through cooperative and coordinated measures to reduce the anthropogenic release of chemicals of mutual concern into the waters of the Great Lakes.” The first chemicals of mutual concern (CMC) list agreed by the countries comprises: hexabromocyclododecane (HBCD); polybrominated diphenyl ethers (PBDEs); perfluorooctanoic acid (PFOA); perfluorooctane sulfonate (PFOS); long-chain perfluorocarboxylic acids (LC-PFCAs); mercury; polychlorinated biphenyls (PCBs); and short-chain chlorinated paraffins (SCCPs). The priorities plan names the identification and assessment of new CMCs as a focus over the next three years. It also calls for the development and coordination of measures to reduce anthropogenic inputs of CMCs into the Great Lakes. Among science priorities are undertaking research, monitoring and surveillance activities to address informational needs for CMCs, in support of future work on the substances. The countriesĀ have also signalled their intent to focus these activities to provide for “early warning for chemicals that could become CMCs.”
