A plate of mosquito coils = 6 packs of cigarettes? a bit exaggerated Expert: Mosquito coils are toxic but this is a bit exaggerated Reporter's experiment: Ignite 10 minutes of smoked yellow wet wipes When the summer is over, the abominable mosquitoes are dispatched again, and the mosquito repellent products in the supermarket are starting to sell. Not long ago, some media reported that a citizen of Nanjing had a night of mosquito coils that caused chest tightness, wheezing, and weakness. So he concluded that after a mosquito coil was burnt out by the superfine particles, the damage caused to the human body was equivalent to one person. Six packs of cigarettes were continuously drawn. A plate of mosquito coils = 6 packs of cigarettes? is this real? The reporter of the Curious Lab decided to break the casserole and ask the question. Investigate a wide variety of mosquito coils in supermarkets The reporter came to a large supermarket, full of shelves filled with insecticides, electric mosquito-repellent incense, disc-type mosquito coils, electro-liquid mosquito coils and other mosquito repellent and anti-mosquito products. The reporter found that among these products, the coiled mosquito coil is the cheapest, and the price of a single box of 10 mosquito coils is about 3 yuan. On the shelves of disc-type mosquito coils, there are 8 brands including radar, all invincible, daisy, and sought-after. The reporter carefully observed the packaging of each brand and found that these mosquito coils contain pyrethroids, some are fenfluthrin, and some are Tefluthrin, some of which are rich in dextro-trans-methyrin, and vary in content depending on the brand, with a high content of 0.08% and a low content of 0.012%. In addition, these mosquito coils have different flavors, some are wormwood and some are sandalwood. The reporter found that most of the mosquito-repellent bags are printed with the word “micro-poisonâ€, and they are marked in the precautions: “Do not let children play, use with caution for pregnant women; be poisonous to fish and silkworms; do not close the doors and windows In the case of use, pay attention to proper ventilation." The reporter spent 3.5 yuan to buy a box of lycopene-type smoke-free mosquito coils with a content of 0.08% of permethrin, ready to use it for a simple experiment. Experimental mosquito coil 10 minutes smoked yellow wipes Experimental props: a glass bottle, a mosquito coil, a piece of paper towel. Experimental steps: 1. The reporter found a glass bottle, smashed a few segments on a mosquito coil, and put it into the bottle after ignition; 2. Find two supports slightly higher than the glass bottle, placed next to the glass bottle; Soak the tissue and place it on the support. The reporter found that the mosquito coils only produced some smoke at the moment of ignition. After being placed in the bottle, there was basically no smoke. After 10 minutes, the reporter found that the paper towel was slightly smoked. After another 20 minutes, the color of the paper towel became yellower. The reporter touched the paper towel with his hand and felt some particles on the paper towel. The wet tissue is smoked yellow and there are particulate residue. Does this mean that mosquito coils such as cigarettes are harmful to the human body? Expert mosquito coils have some toxicity "The pyrethroids added in mosquito coils are all toxic. The pesticide department has regulations on the addition of these substances." Zheng Yiping, a mosquito-control mosquito expert in Nanjing, told reporters that there are many additives in mosquito coils, according to the toxicity. From low to high, there are: pyrethroids or pyrethroids, carbamates, organochlorines, and organophosphorus. "The toxicity is high, the quality is poor for outdoor use, and the indoor quality is good." Zheng Yiping told reporters that in addition to these ingredients, there will be some additives in the mosquito coil. "These additives have no effect, but they are combined with these substances." After that, the effect will be dozens of times." The content of pyrethroids is indicated on the packaging bag of mosquito coils. These contents are high or low. The higher the content, the higher the toxicity, and the stronger the mosquito killing ability? "In theory, this is the case, but it is not. The concentration is high and the toxicity is high, but it is also caused by mosquitoes." Zheng Yiping told reporters that infants, pregnant women and other vulnerable groups have long-term use of mosquito coils for the body. Certain injuries and effects, so these people should use mosquito coils with caution. Is it correct to say that 1 dish of mosquito coils = 6 packs of cigarettes? Zheng Yiping told reporters that this statement has a sensational component. "This should be based on the composition of the mosquito coil, the content of each component and the quality of the mosquito coil. It must be scientifically tested." Zheng Yiping told reporters that the most fundamental anti-mosquito The method is to control the breeding ground of mosquitoes. "Mosquitoes have four stages, adult mosquitoes, eggs, larvae and cockroaches. Except for adult mosquitoes, the other three stages are in the water. It can be said that there is no mosquito without water." Zheng Yiping introduced four anti-mosquito methods to reporters: biological anti-mosquito, physical anti-mosquito, chemical anti-mosquito and comprehensive environmental management. "If there is a pool in the community, we can raise red mullet in the pool, red carp eat mosquito larvae and cockroaches, this is biological anti-mosquito. Physical anti-mosquito can use screen doors, screens, mosquito traps. Chemical anti-mosquito Mosquito repellent, insecticide and other mosquito repellent products. Comprehensive environmental remediation is the combination of the above three methods." >>>What are the links to anti-mosquito methods? When the summer arrives, the mosquitoes begin to appear. How much mosquito-repellent incense and insecticides are harmful to the human body? Is there a better method of mosquito repellent? The reporter collected the following four methods of mosquito repellent for everyone. You can try it according to the actual situation. 1, mosquito killer The mosquito killer uses the phototaxis of mosquitoes to attract mosquitoes by attracting mosquitoes to the high-voltage grid. The power with low power is not enough, and the high power is more effective. Therefore, the effect of choosing a large power is better. It is best to put it 1-2 meters away from the ground, because this is the area where mosquitoes love activities. After a period of time, it is best to change the position to avoid mosquitoes hiding for a long time. In addition, prevent the child from sticking a finger or other electrical conductor into the lamp during use. 2, mosquito repellent Some plants do contain some smells that mosquitoes don't like, such as night primrose, jasmine, Milan, mint, etc., but this needs to be scaled up, and occasional pendulums at home are not effective. 3, odorless electric mosquito liquid The odorless electric mosquito liquid is also toxic, but there is no fragrance added inside. The principle of mosquito repellent is actually like pyrethroids with insecticidal ingredients, so adults (pregnant women, the elderly, patients with respiratory diseases) use it better. 4. In addition, there are some simple anti-mosquito methods: Mosquito nets or screens are used to isolate mosquitoes; raw garlic, oral vitamin B, human body metabolism and excretion from sweat, will produce the smell that mosquitoes can not approach; remove the water in front of the house and indoors to prevent the breeding of mosquitoes; Mosquitoes are most active at 28 to 31 °C, so mosquitoes naturally leave this environment when the air conditioner is below 28 °C.
