Will mosquito coils be poisoned after smelling for a long time? Are mosquito coils toxic?

Slightly toxic , it will hurt a little for a long time. Mosquito coils contain 4 kinds of carcinogens, and the active ingredients of most mosquito coils (which are pyrethroid insecticides, which are extracted from an insecticide of permethrin, and more than 99% of other substances are organic fillers, binders, dyes and other additives, so that mosquito coils can be smoldered without flames.

A poisonous mosquito coil is a mosquito coil made of chemical insecticides such as 66 pesticide powder 223 pesticides and DDT, which can only disperse mosquitoes and insects, but its mist is harmful to human health, and regular use will cause dizziness, nausea and other poisoning phenomena.

In addition, long-term mosquito coil sleeping, the human body inhales too many harmful substances, and has adverse effects on children, the elderly, and pregnant women with rhinitis, chronic branches, and cerebrovascular diseases.

Mosquito coils release toxic gases when burned, so try not to use them if you have children or pregnant women.

Now there are three kinds of mosquito coil ingredients, among which organic phosphorus is the most toxic, and organic phosphorus mainly includes trichlorfon, chlorpyrifos, and pest enemies. The second most toxic is carbamate, such as carbocarb and medicarb. Among them, pyrethrin is the most common, including profenethrin, chlorfluethermethrin, etc., most of which are low-toxicity pesticides.

Because the composition of mosquito coils is different, the harmful gases produced in the burning smoke are also different, among which ultrafine particles (particulate matter with a diameter of less than microns) are the most common, and this ultrafine particles can be inhaled by the human body and affect the human respiratory tract.

Some low-quality mosquito coils also produce polycyclic aromatic hydrocarbons, carbonyl compounds (such as formaldehyde and acetaldehyde) and benzene when burned, all of which are toxic gases, so mosquitoes will die as long as they fly around the smoke ring, and most mosquitoes will stay away when they smell the smell. If ignited in an enclosed space, people can also experience symptoms of poisoning.

If you have children or pregnant women, you must not light mosquito coils, if you buy inferior mosquito coils, they will cause cancer, and they will induce respiratory diseases in children. If you feel that there are too many mosquitoes at home, you can light mosquito coils in the hallway.

There are two types of mosquito coils: one is a toxic mosquito coil, which is made of chemical insecticides such as six or six medicinal powders, two two three pesticides and DDT, which can only disperse mosquitoes and insects, and has no killing effect, but its mist is harmful to human health, and regular use will cause dizziness, nausea and other poisoning phenomena.

Second, the safety mosquito coil is made of herbs such as insecticides, and its smoke can paralyze the nerves of mosquitoes and cause them to die, which is harmless to human health.

Their identification methods are as follows: 1. Look at the appearance of the safety mosquito coil, the processing is fine, the color is uniform, the bending resistance is strong, and the ignition time is about 7-8 hours. If the surface of the mosquito coil is rough, the structure is loose, and there are large particle impurities The crystals of DDT are fine, easy to break, or fail to reach the ignition time, and are extinguished halfway, it can be identified as a toxic mosquito coil.

2.Smell the fragrance After the Chinese herbal medicine, pyrethrum mosquito coil is lit, the smoke is not thick, and people can smell a natural fragrance, without pungent and dizzy feeling; In the process of opening the package and igniting the DDT mosquito coil, there is a smell of mothballs, and people feel dizzy after smelling it for a long time.

3.Distinguish from the ignition point Use a match to light a mosquito coil, a pure pyrethrum mosquito coil only has a yellow flame and a blue-white smoke, while a poisonous mosquito coil burns with a green flame and black smoke.

4.Identification from the ash of mosquito coils The ash of pyrethrum mosquito coils after ignition is white and gray; The ash of the poisonous mosquito coil is black.

5.From the analysis of insecticidal effect, the toxic effect of pyrethrum mosquito coils on mosquitoes is obvious, and it is not easy to see mosquitoes flying indiscriminately after ignition. After the poisonous mosquito coil is ignited, the mosquitoes collide indiscriminately, and the efficacy is not as good as that of the insecticide chrysanthemum.

Many citizens think that the toxicity of electric mosquito coils to the human body is much smaller than that of traditional mosquito coils, and according to relevant experts, in fact, the principle of mosquito repellent is the same as that of traditional mosquito coils, which is the same raw material. Therefore, the statement that "smokeless mosquito coils are less harmful than smoked mosquito coils, and electric mosquito coils are less harmful than disc mosquito coils" is unscientific. However, some counterfeit and inferior mosquito coils contain 666 powder, realgar powder, etc., which will cause chronic poisoning.

Mosquito coils contain toxic substances that are not enough to cause harm to the human body if used normally.

Although the toxic substances in mosquito coils (generally pyrethrins) can be volatile, the state stipulates that the degradation rate of pyrethroid active ingredients should be 10%, and the degradation rate of other active ingredients should be 15%.

Precautions for using mosquito coils:

1. Half an hour before going to bed is a good time to use mosquito coils. When in use, doors and windows are closed, and people and pets must be left.

2. Mosquito coils are best used outdoors, such as around the home, at the door or in areas with air circulation. In the evening, before dark, the mosquito coil has the best effect on mosquito repellent.

3. For safety, it is best not to put the lit mosquito coil near the head to reduce the inhalation of smoke.

Mosquito coil is a kind of insect ester insecticide, which is toxic to the human body when it is not fully burned, so when lighting mosquito coils and smoked mosquito coils, it must be used in a scientific way and correct use.

Usually mosquito coils will release ultra-fine particles, which can enter the human body and stay in the lungs, and inhalation in a short period of time can cause asthma, such as long-term inhalation of large amounts can cause gas poisoning. Therefore, mosquito coils should be lit as far away from the human body as possible, or in a closed, dry and ventilated environment. However, people should leave the environment, and only after the mosquito coil is completely released can they return to the environment where the mosquito coil was lit just now to breathe normally, which is the correct way to use mosquito coils.

Long-term inhalation of a large number of mosquito coils or direct inhalation of mosquito coils by the human body is toxic and harmful to the human body, which will paralyze the nerves of the human body and cause clinical symptoms such as dizziness, nausea, and double vision.

A mosquito repellent in which the smoke emitted by a drug ignited can repel mosquitoes or smoke them. Mosquito coils in China have a very long history, and the traditional mosquito coils are divided into two types: incense sticks and incense.

The smoke burned by mosquito coils contains four types of substances that are harmful to the human body, namely ultrafine particles - soot (particulate matter with a diameter of less than microns), polycyclic aromatic hydrocarbons (PAHs), carbonyl compounds (such as formaldehyde and acetaldehyde) and benzene. At the same time, in addition to these four obvious harmful substances, there are also a large number of organic fillers, adhesives, dyes and other additives in mosquito coils, so that mosquito coils can be smoldered without flames.

01 Toxic.

The main ingredient of mosquito coil is dextrathrin, and its mosquito repellent active ingredient is pyrethroid. Pyrethroid is a low-toxicity and high-efficiency insecticide allowed by the state, and there is a specified proportion in mosquito coils. Regular mosquito coils generally do not pose a danger to the human body, but the use of mosquito coils should still be legal.

Mosquito coils are a daily product used by most people to repel mosquitoes, but mosquito coils have a strong smell, and many people are worried that smelling too much will be harmful to the human body, and many people rely on mosquito coils to repel mosquitoes. So are mosquito coils poisonous?

The main ingredient of mosquito coil is dextrathrin, and its mosquito repellent active ingredient is pyrethroid. Pyrethroid is a low-toxicity and high-efficiency insecticide allowed by the state, and there is a specified proportion in mosquito coils, while other types of insecticides are not allowed to be used casually in mosquito coils. Regular mosquito coils generally do not pose a danger to the human body, but the use of mosquito coils should still be legal.

The smoke emitted during the burning process of mosquito coils contains suspended particles, and some data show that the content of suspended particulate matter in the room can increase to twice that before ignition after the mosquito coils are ignited, far exceeding the national standard.

At present, there are three main types of mosquito coils produced in China:

The first type is a smoked tray mosquito coil, which is mostly filled with plant-based powder, and the amount of suspended particles produced during the combustion process is the largest.

The second type is smokeless tray mosquito coils, which are filled with charcoal powder and emit very little smoke.

The third category is electric mosquito repellent tablets and electric mosquito repellent water, which produce the least suspended particles when used.

If the ingredients are the same, the toxicity of the disc mosquito coil and the electric mosquito coil is the same, but the smoke tray mosquito coil is polluted and produces smoke, which is suitable for use outdoors, on balconies, etc. The sheet type electric mosquito coil and liquid electric mosquito coil are less polluting and suitable for indoor use.

How to choose mosquito coils?

If you choose mosquito coils, it is recommended to choose mosquito coils made of low-toxicity pyrethroid to minimize the toxicity to the respiratory tract, if there are pregnant women or infants at home, it is recommended to use electric mosquito swatters, physical mosquito killers, ultrasonic mosquito repellent and other safe and non-toxic mosquito killer products to avoid the use of mosquito coils.

Mosquito coils are toxic, but it also depends on the dose, generally it is no problem to order two plates in the house, if you do not order ten plates, there will definitely be adverse reactions.

Mosquito coils are poisonous, but that dose of poison is not much harm to people, as long as you pay a little attention to ventilation, there is no harm.

Kiss, mosquito coils are toxic, but moderate use is basically harmless to the human body. Mosquito coil is a kind of artificial mosquito repellent, most of the effective ingredient of mosquito coil is pyrethroid, in addition to the feast of this pyrethroid harm is mainly reflected in the **, eye, nervous and fast menstrual system and respiratory mucosa has a toxic effect, but pyrethroid will only produce toxicity when in large contact, the amount of pyrethroid in mosquito coil is generally small, so it is generally safer for the human body, and the pollution to the environment is relatively small. However, the smoke burned in large quantities of mosquito coils contains 4 types of substances harmful to the human body, namely ultrafine particles - soot, polycyclic aromatic hydrocarbons, carbonyl compounds and benzene, in addition to these 4 types of harmful substances, there are a large number of chemical additives in the mosquito coil, so it will cause certain damage to the human body in the process of burning a large number of mosquitoes, but because the mosquito coil burns slowly and the chemical addition amount of mosquito coil produced by regular manufacturers meets the national standard, a small amount of mosquito coil is basically harmless to the human body.

Ordinary people use mosquito coils, which can be carried out 1 2 hours in advance, extinguished after burning for half an hour, and open the window for ventilation to remove the residue.
