Is the smoke of the mosquito coil harmful to the body?

The smoke of mosquito coils is divided into the smoke produced by the burning of carbon powder + pyrethroid drugs that volatilize into the air at high temperatures, and the overall impact on the body is negligible.

1. The smoke produced by the combustion of carbon powder is actually what we usually call smoke. This seems to belong to the category of pm2.5, which may have a little effect (compared to breathing car exhaust). But the carbon powder is very fine and the mosquito coil burns slowly, so it burns more fully and produces less smoke.

2. Pyrethroid drugs are volatile to the air at high temperature. All mosquito killing products are pyrethroid drugs, which are highly effective and low-toxic pesticides! Toxic and non-toxic? The preparation staff of the company are exposed to polyester technical (96% + concentration) every day. The old employees who have worked for more than 20 years are still alive and well. Every year, there are special occupational health examinations for pyrethroids, which are all qualified, and there has never been occupational contraindications. In addition, the company conducts on-site occupational hazard detection in the production workshop every year, and the detection value is basically 0. Those employees who are exposed to high concentrations every day can live well, so don't worry.

Take the Mosquito Liquid as an example: According to the composition of the Mosquito Liquid, the highest content of pyrethroid is 1.5%, and the total amount of all pyrethroids in each bottle does not exceed 3%. Each bottle is used for about one month, so the average daily consumption is about 0.034g, and only a small part of the volatilized liquid medicine is inhaled through the respiratory tract. The most important thing is low-toxicity, low-toxicity and low-toxicity pesticides. It is very difficult to use this pyrethroid to make you sick... Of course, if you are one in a million allergic physique, it is best to try it first and use it after no allergic reaction.

Mechanism of action

Nerve agents, which poison the nervous system of insects, first induce excitement of insects, then block nerve conduction, and insects convulse, paralyze, and die. The signs of poisoning are divided into two stages, namely the excitement period and the inhibition period. Therefore, two indicators of knockdown rate and lethality rate are commonly used to indicate the characteristics of each species.
