sulfometuron-methyl (Ref: DPX T5648)
** AIDS040010 ** Translations

Environmental Fate - Ecotoxicology - Human Health - A to Z Index - Home

SUMMARY

Sulfometuron-methyl is a herbicide without EU regulatory approval for use. It has a moderate aqueous solubility, is non-volatile and, based on its chemical properties, is mobile and may be expected to leach to groundwater. It is not generally persistent in soil systems but may be persistent in aquatic systems under certain conditions. It has a low mammalian toxicity and has a high potential to bioaccumulate. It is moderately toxic to most aquatic species, honey bees and earthworms but is less toxic to birds.
