1, mosquito lamps are harmful to the human body
Mosquito lamps relative to electric mosquitoes, mosquito incense and other chemical mosquito hair, or more environmentally friendly and healthy, due to mosquito lamps is through the ultraviolet light on mosquitoes and trapping, so if the long-term use of the method is not correct, then it will have a negative impact on the human body.
Fang Wei, associate professor of Zhejiang University Institute of Optoelectronics Technology, pointed out that the mosquito lamps issued by this band of ultraviolet light on the human body is influential, the biggest impact is the skin black, if prolonged exposure may also cause skin aging and other effects.
In addition, prolonged exposure to ultraviolet radiation can also lead to eye damage. That is to say that the mosquito lamps of the ultraviolet light band on the human body is a certain harm.
2, mosquito lamps on the human body
(1) accelerate skin aging black
Mosquito lamps belong to the ultraviolet long-wave ultraviolet A light, can penetrate to the dermis of the skin, the human body, if prolonged exposure to the black light, but also may be able to accelerate the aging of the skin, wrinkles, and even induce skin cancer.
According to dermatologists, daily sun exposure caused by burns is due to ultraviolet radiation caused by wavelengths of 320400nm long-wave ultraviolet, wavelengths of 290320nm medium-wave ultraviolet radiation can cause tanning and aging reaction, wavelengths of 180290nm short-wave ultraviolet radiation is more used for disinfection and sterilization, disinfection lamps are the use of short-wave ultraviolet radiation.
Now on the market a variety of ultraviolet mosquito lamps, wave band impurity, the shorter the wavelength of ultraviolet light on the eye of the more potent injurious effect of the wavelength of 254mm ultraviolet light than the wavelength of 300mm of ultraviolet light on the eye of the role of the strong 10 times. Human eyes and if the ultraviolet radiation for more than 3 minutes, there may be more than the human body's safety threshold and harm; if directly irradiated after 15 minutes, will make the cornea damage, resulting in electro-optical ophthalmia, double eyes suddenly severe pain, foreign body sensation, photophobia, tearing or eyelid spasms, etc., long-term exposure to strong ultraviolet rays will trigger blindness. The human body if long-term exposure to ultraviolet light and ultraviolet light irradiation, will lead to eye trauma and skin cancer and death, and thus ultraviolet light has been strictly limited to the medical category, can not be easily used in the public **** place.
(2) secondary pollution
Photocatalytic mosquito extinguishers using mosquitoes favorite ultraviolet light mosquito lamps, trapping lamps emitting ultraviolet wavelengths of 360-380 nanometers, which uses the mosquito phototropism, mosquitoes attracted to the air-drying or electrocuted to death, this mosquito lamps are prone to serious secondary pollution, when the mosquito body is When the mosquito body is air-dried or electrocuted instantly, it will spread a large number of germs in the body to the air and the surface of objects.
(3) purple light health risks
Purple light, purple appliances are used as a profit-making tool. Last year by the Xinhua News Agency and the China Consumers Association red light purple appliances have recently begun to surge, some of the purple appliances under the banner of ultraviolet light, purple micro light, purple fungus light and so on have been pink. Industry experts believe that, due to the ultraviolet light technology content is low, low cost, high price, consumers of purple appliances, the disadvantages of more than less and do not know, so many manufacturers to make high profits, they have to play the banner of ultraviolet disinfection. Ultraviolet disinfection is used in medicine, biology and other professional fields, only in a strictly closed state of use to have security. Now you can buy in some supermarkets or home appliance stores, and manufacturers and consumers have ignored the ultraviolet disinfection is very easy to hurt the eyes and skin, a huge threat to human health lurks.
(3) room no one use
However, the mosquito lamp on human health impact is relatively limited. As long as you pay attention to the method, you can reduce the harm.
Generally mosquito lamps work when people are not present, because the human body is much more tempting to mosquitoes than mosquito lamps, this general instructions will be explained. So mosquito lamps on the human body is more or less some impact, but talk about great harm is alarmist, because mosquito lamps only in the case of no one can work effectively. Turn on the mosquito lamp to try to people are not present, but also do not go to bed at night, that not only is not good for the human body, but also will make the effect of mosquito lamps discounted.
Under the existing technical conditions, the light used for photocatalysis can already be from ultraviolet to far infrared. But as the wavelength increases, the higher the technical requirements, while the ultraviolet belongs to the lower stage, the product price is relatively cheap. So for the use of ultraviolet light mosquito lamps, if you want to reduce the harm to the human body, you can choose to open the mosquito lamps when no one, or pick the market quality is better, less harmful to the human body mosquito repellent lamps, and even the use of mosquito nets and other more primitive methods, so that you can play the role of mosquito control, but also to protect their physical health.
3, mosquitoes are afraid of the smell
1, garlic flavor
Garlic special pungent flavor will allow mosquitoes to hide far away, garlic consumption, will leave a substance called methyl allyl sulfide, this flavor is more for the mosquitoes to avoid, a time you can cut the thin skin of the garlic placed indoors or coated in the screen windows to stop mosquitoes from approaching.
2, geraniol odor
Geraniol is a by-product of alcohol and sorbate, can be used as a food preservative. Studies have found that candles containing geraniol can disperse 50% of female mosquitoes indoors, and diffusers are 97% effective. Geraniol also repelled approximately 74% of mosquitoes outdoors, and diffusers within a 9-foot radius were 96% effective in repelling mosquitoes. Thus proving that the odor emitted by geraniol is feared by mosquitoes.
Plants rich in geraniol include: nine-leaf clover, bay laurel, scented geranium, garlic, and Elsholtzia.
3, linalool odor
Linalool itself is quite fragrant, is a terpene alcohol chemical that can be found in different flowers and plants. It's often used as a soap and detergent, but it also has a mosquito repellent effect.
Studies have found linalool to be slightly less effective at repelling mosquitoes than geraniol, with a 93 percent indoor repellency rate for diffusers and an 89 percent outdoor repellency rate within a 9-foot radius.
Plants rich in linalool: baking tobacco tobacco, white ribbed tobacco tobacco.
4. Odor from citronella
Citronella oil is an essential oil derived from the tropical plant lemon coriander. Although people have been using citronella as a mosquito repellent since ancient times, studies have found it to be less effective than geraniol or linalool, with citronella diffusers repelling only 68 percent of mosquitoes indoors and 66 percent outdoors. Citronella candles only disperse 15 percent of mosquitoes indoors.
5, other scents
In addition to the above scent, there are a few other scents also have mosquito repellent effect. Peppermint oil can also disperse mosquitoes, but it is toxic and can only be used by certified herbalists. Lavender oil or cinnamon oil are also better alternatives that not only repel mosquitoes but also relieve itching caused by mosquito bites. The aroma given off by plants such as nightshade, thyme, and insectivorous herbs also have mosquito repellent properties.
