The production of PeCB ceased some decades ago in the main producer countries as efficient and cost-effective alternatives are available. Applying Best Available Techniques and Best Environmental Practices would significantly reduce the unintentional production of PeCB.

Note that following information is extracted from the risk management evaluation document (UNEP-POPS-POPRC.4-15-Add.2).

As there is no current commercial demand for PeCB, no alternatives have been identified or developed For the production of quintozene, an alternative process using the chlorination of nitrobenzene is available.

If you have any information or suggestion for alternatives to Pentachlorobenzene, Please contact the Secretariat.
