A study found that electric mosquito liquid has hepatotoxicity? Tell you the truth

Electric mosquito coils, also known as hygienic insecticides, belong to a kind of pesticide. Currently on the market electric mosquito coils, effective mosquito components are mainly "pyrethroids". The liquid electric mosquito is the use of hair straw principle, continuous heating to release insecticide substances to achieve the effect of mosquito.

Pyrethroids are broad-spectrum insecticides that can control a wide range of pests, and their most significant advantage is that they are highly effective, requiring only a low concentration to knock down mosquitoes.

However, although pyrethroids can be metabolized and excreted after being absorbed by the human body, they are still slightly toxic and can have a certain effect on the human nervous system, and prolonged exposure may also cause symptoms such as dizziness, headache, abnormal neurosensory sensations, and even nerve paralysis.

In that case, is it true that electric mosquito liquid can't be used? In fact, according to the U.S. Environmental Protection Agency (EPA) on the "pyrethroid" health risk assessment, infants and children on its sensitivity is not higher than that of adults, and there is no evidence that it will cause adverse effects on the long-term health of adults or children.

It is important to note that children should not be allowed to come into direct contact with the liquid to avoid accidental ingestion.

Children accidentally eat mosquito liquid, nausea, vomiting, as well as abdominal pain, diarrhea and other gastrointestinal symptoms, if ingested in large quantities, without timely treatment, the toxicity can act on the whole body, especially the nervous system, resulting in shortness of breath, short-term slow reaction, but also obvious tremor, convulsions. In critical cases, coma or even death may occur.

So, if you want to use electric mosquito liquid at home, try to put it in a high place out of reach of children, do not put bulk or liquid drugs, such as laundry detergent, pesticides, etc. into plastic bottles.

Two, why mosquitoes favor only bite you?

Previously, there have been claims that mosquitoes prefer O-type blood group, in fact, this is not reliable.

The top international academic journal Cell has published a research paper from the Tsinghua University School of Medicine's Prof. Cheng Gong's team. The study found that body odor is a key factor in regulating mosquito behavior, and that viral infections increase the proportion of specific bacteria in human skin, significantly increasing the ability of infected people to release acetophenone, which significantly improves the behavioral tendency of mosquitoes toward infected hosts.

Based on these findings, the research team proposed a new strategy to combat mosquito-borne viral infections: the rapid spread of mosquito-borne viruses can be blocked by modulating human odor. For example, vitamin A or related drugs can be supplemented to specific infected populations to avoid mass transmission epidemics of mosquito-borne viral infections.

The Tsinghua study tells us that mosquitoes prefer people with higher levels of acetophenone, and that the following four groups of people may be the mosquitoes' "preferred candidates.

1, drinkers

People who drink a lot of alcohol, especially beer, sweat alcohol and metabolic formation of acetic acid and other acids, will be more mosquitoes than not drink.

2, often make-up people

Many cosmetics contain stearic acid, which is the mosquito favorite chemical, if the body sprayed with perfume, may be more mosquito than others.

3, wearing dark-colored clothes

Black, purple, red dark-colored clothing, reflective effect is relatively weak, in line with the mosquitoes were born to like "dark" visual preferences.

4, the metabolism of the people

Love sweating people, the sweat of the body by the bacterial decomposition, will emit a mosquito heartbeat body odor. People with a high basal metabolic rate, high metabolism, and high CO2 exhalation rate, such as pregnant women, exhale 20% more CO2 overall than normal, and are therefore also more attractive to mosquitoes.

Three, mosquitoes are pests, why can't they be exterminated?

Annoying mosquitoes like a "vampire", once they are staring at them, inevitably have to suffer. In addition, mosquitoes spread disease, with more than a million people dying each year from malaria, dengue fever, yellow fever and other mosquito-borne illnesses.

If that's the case, why don't we just get rid of them? Because not all mosquitoes are harmful.

Most mosquitoes are vegetarians, sucking nectar, plant sap and juices and never sucking blood, and a few plants rely on mosquitoes for pollination.

Considering that mosquitoes are a major source of food for many animals, including: bats, birds, frogs and dragonflies, eliminating mosquitoes completely could be counterproductive with some ecological impacts.

It would be great if there wasn't a single mosquito on the planet, but at the moment we can't achieve that, and we have to rely on some anti-mosquito measures to stay away from these "vampires".

1, physical mosquito

Physical mosquito is the most recommended means of mosquito control, including mosquito nets; in the home set up screens, screen doors; electric mosquito swatters, electric mosquito lamps to kill mosquitoes; wear anti-mosquito pants, anti-mosquito sleeve, etc., cheap and can be operated, has the advantage of environmental protection, non-toxic.

2, chemical mosquito repellent

Anti-mosquito amine (DEET) is a representative of synthetic repellents, has been widely used for 70 years, can guarantee the safety and effectiveness. It is recommended to use the age of 2 months of age or older, safe concentration <30%, 2 months ~ 12 years old recommended concentration of 10% ~ 30%.

Lastly, Xiaojiu would like to remind everyone that after being bitten by mosquitoes, it is best not to vigorously scratch, pinch the cross-meter character, apply saliva and so on.

Because the main component of mosquito saliva is anticoagulant, anticoagulant injected into the human body will cause an immune response, resulting in localized bag, become itchy. Scratching and other methods do not actually stop the itching and swelling effect, but may make the mosquito bag bigger and bigger, more and more itchy, and even induced infection.

After being bitten by a mosquito, the easier and more correct way to stop the itching is to apply a localized antipruritic agent to the itchy area. If the itching is significant, you can consult your doctor before regulating the use of medication.
