The full text of the final screening assessment report is available at:

Based on information submitted during the public comment period that followed the publication of the draft assessment regarding the actual concentration of ethylene glycol in latex paint and ethylene glycol-specific model parameters, estimates for the general population are no longer considered to be of concern. Therefore, the final conclusion is that ethylene glycol is not entering the environment in a quantity or concentration or under conditions that may constitute a danger to human life or health and does not meet any of the criteria in Section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). It is proposed to take no further action on ethylene glycol at this time under section 77 of the Act.

"Notice of Suspension of five-year period" and State of the Science

On December 2, 2000 a "Notice of suspension of five-year period" for ethylene glycol was published in the Canada Gazette Part I, pursuant to subsection 78(2) of the Canadian Environmental Protection Act, 1999 (CEPA 1999). This suspension was announced for ethylene glycol because there was a lack of information necessary to conclude on the toxicity of the substance from a human health perspective.

A State of the Science (SoS) Report on ethylene glycol was released at the same time as the Notice of suspension of five-year period by Environment Canada and Health Canada, to provide an in-depth review of the available toxicity and exposure information related to human health and the environment.
