 |
(Also known as: demeton-S-methyl sulphone ; demeton-S-methylsulphon ; methylsystox sulfone) |
Demeton-S-methyl sulfone is an organophosphate insecticide. Very little data is available regarding its environmental fate or its ecotoxicology. Demeton-O-methyl sulfone is highly toxic if consumed, is an acetylcholinesterase inhibitor and a neurotoxin. |
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.
