The severity of Organic Phosphorus poisoning is related to the types of Organic Phosphorus, the dose of poisoning, the body's absorption of toxicants and the rate of exclusion. In general, in addition to a small number of Organic Phosphorus pesticides (such as Fenxinsong) slow symptoms, most of the poison in a few minutes to twelve hours, there will be symptoms, poisoning after treatment without death, Occurred in six hours.
