As noted in PSRD2019-02, Health Canada will be initiating a cumulative risk assessment for the organophosphate class of chemicals upon completion of the re-evaluation of the individual chemicals in this group. These decisions in the current document for the naled special reviews represent the last of the re-evaluations/special reviews of the organophosphates in this re-evaluation cycle, and as such the organophosphate cumulative risk assessment will be initiated shortly, with a formal announcement to follow.
