Proposed Risk Management Strategy for Pentachlorobenzene and Tetrachlorobenzenes


On April 3, 2004, the Ministers of the Environment and Health published the Follow-up Report on Five PSL1 Substances for Which There Was Insufficient Information to Conclude Whether the Substances Constitute a Danger to the Environment. The report concludes that both pentachlorobenzene and tetrachlorobenzenes are toxic to the environment because they are entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity.

A proposed Risk Management Strategy was developed by Environment Canada with input from Health Canada, to address sources of pentachlorobenzene and tetrachlorobenzenes. This proposed Strategy outlines the risk management objectives, approaches and instruments to reduce the risks associated with penta- and tetrachlorobenzenes.

Environment Canada is inviting comments from interested stakeholders on this proposed Risk Management Strategy. In particular, Environment Canada is requesting comments from stakeholders on:

  1. the planned addition of the substances to the Prohibition of Certain Toxic Substances Regulations; and
  2. the effect of the efforts currently in place regarding dioxins and furans and what their impact could be on penta- and tetrachlorobenzene emissions.
