Health hazards: This product has an inhibitory effect on pseudocholinesterase in the body, but does not inhibit true cholinesterase. The ortho isomer (TOCP) is mainly responsible for delayed toxic neuropathy, while the meta - and para isomers are actually non-toxic and do not cause neuropathy.

Acute poisoning: When taken orally in large quantities, nausea, vomiting, and diarrhea first appear, which subside in about 1-2 days. Delayed onset neuropathy usually occurs after 7-28 days, mainly in the motor type. It often begins with severe spasmodic pain in the gastrocnemius muscle, which may be accompanied by mild sensory abnormalities in the lower limbs. Later, there may be weakness in the lower limbs, which rapidly progresses to obvious flaccid paralysis. In severe cases, pyramidal tract sign may also appear. The recovery speed of neurological symptoms and signs varies significantly among individuals. It can also be absorbed through the skin and respiratory tract.

Chronic poisoning: Long term exposure to small amounts of adjacent triphenylphosphate can cause neurological damage similar to acute poisoning.
