Request for Special Review of Mancozeb Under the Pest Control Products Act

The document argues that mancozeb and its metabolite ethylene thiourea (ETU) pose unacceptable risks to human health and the environment, citing a 2021 European Union ban and deficiencies in Canada's regulatory oversight. The requesters claim the PMRA has failed to implement its own 2020 risk mitigation measures, ignored critical biomonitoring data showing widespread ETU exposure in Canadians, and relied on outdated US water monitoring data to underestimate cancer risks. They specifically highlight risks of endocrine disruption, reproductive toxicity, and harm to non-target arthropods, birds, and aquatic organisms, demanding a special review and the suspension of product renewals.

• The requesters seek a special review under section 17(2) of the Pest Control Products Act (PCPA) because the European Union prohibited all uses of mancozeb in 2021, and a notification was given under the Rotterdam Convention in December 2022.
• Mancozeb and its primary metabolite, ethylene thiourea (ETU), are linked to severe health effects, including thyroid hormone disruption, potential carcinogenic effects (specifically liver tumors), neurodevelopmental damage, and reproductive dysfunction.
• The PMRA's 2020 re-evaluation decision required numerous risk reduction measures—including lower application rates, increased personal protective equipment, and restricted-entry intervals (REIs)—which the requesters claim have not been implemented on public labels as of September 2023.
