Canada | The Final Screening Assessment for the Phthalate Substance Grouping was published.



Considering all available lines of evidence presented in this screening assessment, there is low risk of harm to the environment from the 14 phthalates in the Phthalate Substance Grouping (DMP, DIBP, CHIBP, BCHP, DCHP, DBzP, B79P, DMCHP, DIHepP, BIOP, B84P, DINP, DIDP and DUP). However, there is risk of harm to the environment from 1 additional phthalate, DEHP. DEHP was previously assessed by Environment Canada and Health Canada in 1994 under the Priority Substances Assessment Program. The assessment concluded that DEHP posed a risk to human health in Canada. However, a conclusion for the environment could not be determined because of insufficient information.
