cholinesterase and act by inducing muscle paralysis. They may be absorbed through the skin and are dangerous by inhalation or ingestion. Low: Triaryl phosphates have low acute toxicity. Extreme: The organophosphate pesticides are acutely toxic, Acute toxicity inducing symptoms salivation, lachrymation, vomiting and laboured breathing. Low: Triaryl phosphates have low chronic toxicity but see below for reproductive effects. Medium: Chronic effects of longer term exposure to organophosphate pesticides are of the same type as the acute Chronic toxicity effects and result from decreased levels of the relevant enzyme causing reduced muscular control. Such effects may be induced by slow-release formulations of the organophosphate pesticides that are designed to maintain very low concentrations of the substances in indoor environments. Neither the triaryl phosphates nor the organophosphate pesticides Carcinogenicity are carcinogenic Medium: Triaryl phosphates have reproductive toxicity, the mechanism of which is unknown. Reproductive toxicity The organophosphate pesticides do not pose a reproductive risk to humans. Workplace Workplace exposure must be avoided to the maximum extent possible. Spray and jetting health & safety applications pose particular risks and require the use of face masks. Periodic testing of workers is recommended by Safe Work Australia. impacts Permitted residue levels for organophosphate pesticides on grains and other vegetable Population products are typically a few mg per kilogram on treated product and withholding intervals scale impacts of typically 7 days after treatment. No significant data are available on the environmental impacts of triaryl phosphates. Overview Organophosphate pesticides are toxic to animal species. Extreme: As for humans, the toxicity consists of muscle impacts Acute ecotoxicity caused by enzyme inhibition. Very toxic in aquatic environments. Potential Extreme: As for humans, continued exposure results in low level environment Chronic impacts of the same kind as acute poisoning. May cause long term impacts ecotoxicity adverse impacts in the aquatic environment. Low: Triaryl phosphates are slowly degraded in the environment and so are not persistent. Persistence Organophosphate pesticides are not persistent in the environment, but some degradation products are toxic and have longer lifetimes.
