As one of the thousands of creatures on the earth, it is doomed that not only small animals are budding, but also annoying mosquitoes, flies, lice and ants are often found in our daily life.
Not only do mosquitoes, flies and lice not only look unpleasant, but many of them will also cause damage to agriculture, forestry, animal husbandry and other industries, and some will even endanger people’s health. It is also because of this that the use of various pesticides is also very common in daily life.
Insecticides are naturally used to kill insects, but the toxicity of insecticides is not only aimed at insects. Improper use will also cause accidental injury to people!
The following Ding Ma will take two examples to talk about the safety of these pesticides.
I. Poisoning by Miehailing
Miehailing is an insecticidal aerosol, which is mainly used to kill mosquitoes, flies, cockroaches, etc. It contains toxic components such as permethrin, cypermethrin, dextrotrans-allyl rich, etc.
Insecticidal aerosols have many brands and were widely used before the appearance of electric mosquito-repellent incense. However, this aerosols are very easy to be absorbed through skin and respiratory tract, especially in closed or poorly ventilated rooms, and are easy to inhale too much and cause poisoning.
Skin absorption may cause skin numbness, tingling, pruritus and other symptoms, while respiratory inhalation may cause sneezing, runny nose, cough and other manifestations. When poisoning occurs, mild cases may cause headache, dizziness, nausea, vomiting and other symptoms, and severe cases may cause convulsions and coma.
Just this summer, I heard of a tragedy of exterminator poisoning.
A friend of a friend sprayed a damaging spirit in his room at night to kill mosquitoes. He only opened the doors and windows for a while, and the family of four went to sleep with the air conditioner on.
Later, the two adults appeared dizziness, nausea and vomiting one after another, but they all mistakenly thought that they had eaten a bad stomach outside during the day and did not pay attention to it. After midnight, the adult’s symptoms became more and more serious. At this moment, the little daughter of more than two years old was unconscious and was rushed to the hospital and failed to rescue her.
Perhaps because many insecticidal aerosols are tasteless and fragrant, many people ignore that insecticides are toxic. Even if it is clearly written on the bottle that “people and animals should leave the room after spraying, close doors and windows for 20 minutes, and fully ventilate when entering again”, there are still many people who fail to attract enough attention.
When poisoning is found, you should stay away from the scene, go to a place with fresh air, change contaminated clothes and rinse your skin with clear water.
But unfortunately, the parents did not know this…
There are many mosquito repellent methods. Mosquito nets or some safe and effective mosquito repellent agents, such as DEET and mosquito repellent ester, can achieve good mosquito repellent effect. The most important thing is that these methods are relatively safe.
If you must use the evil spirit, please remember to fully ventilate! Ventilation! Ventilation!
II. Aspiration of Phosphine Gas
A few days ago, I saw a colleague in the professional group and asked which hospital had cytochrome C injection. The two children were poisoned and needed this medicine urgently. At the same time, the local news also appeared the headline [XXX died and was injured due to smoked wheat poisoning].
What is [smoked wheat medicine]? People who have lived in rural areas may not be unfamiliar with it. Every summer, in order to prevent wheat from growing insects, several wrapped aluminum phosphide sheets are put in the wheat hoard to kill insects.
Aluminum phosphide belongs to fumigation insecticide, which is made of red phosphorus and aluminum powder. It is widely used due to its high insecticidal efficiency, less residue for grain and low price.
Aluminum phosphide tablets can produce phosphine gas when exposed to water or in humid air. However, phosphine gas has severe toxicity to human body, causing hypoxia and poisoning.
Mild poisoning will cause nausea, dizziness, cyanosis of lips and other manifestations. In serious cases, death will occur due to severe hypoxia.
Aluminum phosphide tablets sold on the market are cheap and easily available, and stores that are slightly responsible when buying drugs will explain: [This drug is toxic], but most people do not know that inhalation of this drug can cause poisoning or even death.
Moreover, there is no specific antidote for phosphine poisoning, and only emesis, gastric lavage, activated carbon adsorption, oxygen inhalation, fluid infusion and other measures can be adopted to support symptomatic treatment.
The cytochrome C mentioned at the beginning has certain effect on the treatment of phosphine poisoning, but the effect is not good either.
If you search for the news of the death from poisoning by smoked wheat drugs, you will find that there are really many such tragedies, basically every year, several times every year.
Some were poisoned by playing in the room where the granary was placed, and some were poisoned by sleeping in the room where the granary was placed. When such poisoning incidents occurred, the most serious or dead ones were often children, and some were found only hours after poisoning, abruptly missing the best treatment opportunity.
Therefore, parents must remember that they must not let their children enter the closed room where aluminum phosphide is placed. Even if adults want to go in to put medicine or check wheat, they must also pay attention not to take too long, and must open the door and open the window to ensure ventilation!
Miehailing and aluminum phosphide, Only two of many pesticides, and in addition to pesticides, there are also some other poisons in daily life, such as some cleaning products. In addition to using them according to the specifications of the instructions, attention should be paid to proper storage, such as keeping them out of reach of children or locking them with locks. In short, children must not be exposed to them.
