hot summer days, frequent mosquito bites are annoying, and mosquito repellent products are also hot. In addition to mosquito repellent, insecticidal aerosol and other traditional mosquito repellent products, some new products, such as mosquito repellent software, mosquito repellent ring, and photocatalyst elimination device, have been developed in the market and shopping websites, which have been loved by many young consumers. Recent party newspaper hotline reporters found that these products are not as effective as those advertised by merchants, and others may damage their health.
recently, a number of citizens have reported to the party newspaper hotline that one kind of mosquito repellent software is very popular on the Internet, and I don't know how it works. After entering the "mosquito repellent software" on Baidu, the reporter had more than 1 million 700 thousand search results, and the "mosquito repellent master", "mosquito repellent master", and "electronic mosquito incense" appeared. According to the website, "mosquito repellent" is a mosquito repellent software developed on the basis of the principles of bionics, which uses the small horn of a computer box to produce the same frequency of mosquito natural enemies as dragonflies, bats or male mosquitoes to drive mosquitoes.
according to experts, a human ear can hear a sound frequency of 20-20 kHz, while bats, dragonflies, and male mosquitoes all sound ultrasonic, and the bats are more than 300 thousand Hertz. That is to say, to play the role of mosquito repellent, it is necessary to play the ultrasonic equipment in the playback equipment. But both the speaker and the cell phone are designed for the human ear, and the ears of 20 thousand Hertz can hardly be heard, not to say more than 20 thousand times the ultrasonic wave over 20 thousand Hertz. At the same time, a long buzz can also make people feel dizzy, irritable, tinnitus, and so on, thus affecting health, especially for pregnant women and infants. Professionals from the Ji'nan Center for Disease Control and prevention also say that mosquitoes rely on the chemoreceptor on their beaks to look for targets. According to the current level of science, they are not able to test what sounds sensitive to mosquitoes, and the software that claims to use ultrasound to repel mosquitoes lacks scientific support.
in the Watsons store of four Wanda Plaza, there are many brands of mosquito repellent stickers and mosquito repellent bracelets. The reporter picked up a "HELLOKITTY mosquito repellent ring", and saw the packaging on the ingredients for citronella essential oil, lemon press oil, mint essential oil and so on, and especially marked "made of plant essential oil, never contain any chemical ingredients such as mosquito repellent, non-toxic and harmless". A nearby consumer said he had bought similar bracelets before, and the mosquito repellent effect was not obvious. Reporters bought this "HELLOKITTY mosquito repellent Bracelet" after the torn package, immediately smelled a very pungent odor. A doctor at Department of Dermatology, Qilu Hospital of Shandong University said that most mosquito repellent products have some harm to the human body. Some mosquito repellent rings and mosquito repellent stickers are produced by the volatilization of the aromatics contained in the product, and benzene may be contained in the aromatics. It has a strong stimulating effect on the respiratory mucous membrane and nasal mucosa of the human body.
on a large shopping website, many businesses are selling photocatalyst environmental protection mosquito killer, intelligent environmental protection light control LED mosquito trap. According to the introduction, the technology of LED ultraviolet light imitating human body attraction and so on has been used to catch mosquitoes and kill them. The efficiency of mosquito control is as high as 99.5%. However, many netizens are inconsistent with the store's description. A netizen commended, "this mosquito killer has not caught a mosquito so that I am bitten by mosquitoes every night. Do not buy it!"
