|
(Also known as: chlorfénizon; ephirsulfonate; ovatron; ovex; chlorfenizon) |
Chlorfenson is an obsolete insecticide. It has a low aqueous solubility and a low volatility. Data on its persistence in soil and water systems is missing. It has a low mammalian oral toxicity and thought to be a skin irritant. data on ecotoxicology is scant but it does appear to have a low toxicity to birds and a moderate toxicity to fish. |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
