Toxicology:

It is of low toxicity and excretes quickly in the body. It is basically discharged within 24 hours.

Acute toxicity:

The chemical structure of this product is very similar to methyl parathion, but its toxicity is relatively low. Its purity is 98.
The oral LD50 of 8% mice was 870mg/kg, and the percutaneous LD50 was more than 3,000. The oral LD50 of rats is 250mg/kg and the
percutaneous LD50 is 700mg/kg, which is 2 times higher than the toxicity of mice.

Chronic toxicity:

Rats were fed with cartap-containing feed for 16 weeks with a content of less than 160ppm, and the weight gain of each group was
not significantly different from that of the control group. Regarding the changes of ChE activity in plasma and red blood cells,
there was no effect below 40ppm, while significant decrease was observed in 80 and 160ppm groups. In terms of pathological tissue,
there was no difference between the groups below 160ppm and the control group.

Mutagenicity:

According to domestic reports, cartap is positive for TA100Ames test, and its effect on SCE of human peripheral lymphocytes
increases with increasing dose. when > 40 g/ml, there is a statistical difference compared with negative control group. However,
