US EPA starts fumigant reviews
The US EPA has issued preliminary work plans for a group of fumigants entering the registration review process. The reviews for metam sodium, metam potassium, methyl isocyanate (MITC), dazomet and chloropicrin are due to be completed in 2019. Reviews for 1,3-dichloropropene (1,3-D), aluminium phosphide, magnesium phosphide, phosphine, methyl bromide and propylene oxide (PPO) should be completed in 2020 and for ethylene oxide (ETO) in 2021. The Agency expects to conduct comprehensive ecological risks assessments, including endangered species assessments, for all of the fumigants and updated human health risk assessments for all except chloropicrin.
