Release of the Final Screening Assessment Report

On November 28, 2009, a notice of final decision with respect to the final screening assessment report on phenol, 2-methyl-4,6-dinitro-, also known as 4,6-dinitro-o-cresol (DNOC), was published in the Canada Gazette, Part I. A summary of the final screening assessment report on DNOC is available at:

• Canada Gazette, Part I: Publication of Final Decision on the Screening Assessment of a Substance - Phenol, 2-methyl-4,6-dinitro- (DNOC) - CAS No. 534-52-1 - Specified on the Domestic Substances List (Subsection 77(6) of the Canadian Environmental Protection Act, 1999) (PDF Version)

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

• Final screening assessment report on DNOC (PDF Version)

Based on consideration of the effects of DNOC and the exposure in Canada, the final assessment concludes that DNOC does not enter the environment in a quantity or concentration or under conditions that a) have or may have an immediate or long-term harmful effect on the environment or its biological diversity, b) constitute or may constitute a danger to the environment on which life depends, or c) constitute or may constitute a danger to human life or health. Therefore, DNOC does not meet any of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999. The Ministers of the Environment and of Health therefore intend to take no further action on DNOC under the Act at this time.
