What are some highly toxic substances in life? What are the chemicals that are highly toxic?

Thanks for asking! The scope of this problem is too large, because in our daily life, we will encounter or hear about highly poisonous snakes, scorpions, centipedes and other animals, as well as poisonous mushrooms, mandalas, wolf poison flowers and other fungi or plants, and even including the rice and peanuts we often eat.

With the improvement of people's living and working environment, more and more rooms and offices will be placed with some flowers and plants and other potted plants to decorate, and some plants also have the meaning of "red and prosperous", "smooth sailing" and "fortune tree", so they are also particularly cute, but do you know, in fact, some plants are poisonous, the following small land to simply take stock of those poisonous plants in life (common top 3)!

1. Pothos

Pothos is an evergreen vine plant, which is favored by many people because of its developed aerial roots, easy to feed, and can be grown hydroponically and easy to care for.

However, it should be noted that pothos can absorb toxic gases such as formaldehyde and benzene, and its juice is also toxic.

2. Dripping Guanyin

Guanyin is a perennial herbaceous plant of the family Alocasia, which is a large foliage plant, because of its large leaves and thick stems, it looks very atmospheric, so it is suitable for halls, receptions or gardens. However, it should also be noted that the scientific name of Guanyin is Alocasia, although it also has a "taro" character, but it is poisonous all over the body, not only that, but the water it drips is also poisonous, so it is necessary to pay special attention, and it may cause swelling and numbness of the contact site if it is not careful, and even the symptoms of central nervous system poisoning.

There have also been cases of eating the leaves of the dripping Kannon as a fungus and the stems as taro, so it is necessary to pay special attention to the elderly and children in the family.

3. Oleander

Oleander is more common in the south of our country, because it has the characteristics of long flowering period and high ornamental value, so it is widely planted in parks, scenic spots, and even on both sides of some roads or ** isolation zone.

However, although oleander is beautiful, it is one of the poisonous flowers, and its body contains a variety of toxins, some of which are even deadly, so be very cautious where oleander is grown.

Some pesticides used to repel insects in rural areas are very toxic, such as paraquat, and there is almost no time to rescue them. There are also some cyanide, moldy and spoiled foods, and generally a lot of aflatoxin, which can cause organ failure if accidentally eaten.

Potatoes are highly poisonous when they sprout, and oleander, although it blooms beautifully, but its leaves are highly poisonous, and daffodils, which may cause vomiting and excitement if eaten by mistake.

All substances containing cn- ions are highly toxic. In addition, HCN, (CN)2 and isocyanic acid and their esters are highly toxic, and some glycosides that can produce CN- after hydrolysis, the same is true (such as bitter almonds, which can be poisoned by oral administration of more than 10 capsules).Generally, cyanide enters the body to produce CN-, which is a cellular plasma poison and has an inhibitory effect on dozens of oxidases, dehydrogenases and decarboxylases in cells.

However, it is mainly combined with the trivalent iron of oxidized cytochrome oxidase in the mitochondria of cells, which prevents the reduction of ferric in the oxidation enzyme, which also blocks the electron transmission in the oxidation process and inhibits the formation of ATP, and finally makes the nerve cells and cardiomyocytes in the human body die without energy utilization, and the person dies quickly within a few minutes. Generally, the lethal dose of inorganic cyanide is within 100 mg.

Antidote: sodium thiosulfate (can be used alone for mild poisoning), sodium nitrite (used with the former in severe poisoning), if it is severe poisoning. If you can't get to the hospital, you have to hang up.

(1) Corrosive poisons. Including corrosive acids and alkalis, such as sulfuric acid, hydrochloric acid, nitric acid, phenol, sodium hydroxide, ammonia and ammonia hydroxide. (2) Destructive poisons.

Poisons that can cause tissue damage in living organisms. Such as arsenic, mercury, barium, lead, chromium, magnesium, thallium and other heavy metal salts. (3) Poisons that impair function.

Such as poisons that impede cerebrospinal cord function, such as alcohol, methanol, hypnotic sedatives, tranquilizers, caramine, atropine, isoniazid, opium, cocaine, amphetamines, hallucinogens, etc.; Poisons that impair respiratory function, such as cyanide, nitrite, and carbon monoxide. (4) Pesticides. Such as organophosphorus, carbamates, pyrethroids, organic mercury, organochlorine, organic fluorine, inorganic fluorine, chlormequatin, chlorpyramide, chlorothalonil, paraquat, potato blast tin, methyl bromide, chemical zinc, etc.

5) Rodenticides. Zinc phosphide, anti-rat strong, Anto, anti-rat sodium, rat kill, etc. (6) Toxic plants.

Such as aconitine plants, hook kiss, mandala, oleander, poisonous mushroom, mangweed, red fennel, tripterygium wilfordii, etc. (7) Poisonous animals. Such as snake venom, pufferfish, cantharid, toad, fish gall bladder, bee venom, etc.

8) Bacteria and mycotoxins. Such as salmonella, botulinum toxin, staphylococcus and other bacteria, as well as aflatoxin, mildew sugarcane, black spot sweet potato and other fungi.

Let's talk about two deadly, there is always a need for disinfection recently, and some 84 will be bought at home, note that 84 cannot be mixed with acidic toilet cleaners, which will produce toxic gases, and if you smoke too much, you will be gone.

It's too much, I can't say it, if you're interested, you can check it yourself.

Methanol, which is mixed with methanol in industrial alcohol, often causes people to be poisoned by mistake.

2] Hydrogen sulfide gas.

3] Carbon monoxide gas (coal gas).

4] Mercury (mercury in the thermometer).

5] Nitrite, such as sodium nitrite and table salt, is often used as salt by unscrupulous traders**.

6] Nitrogen oxides (fossil fuel combustion, automobile exhaust) and sulfur dioxide (produced by burning fossil fuels).

8] Lead (burns leaded gasoline).

9] Aflatoxin (high content of sprouted potatoes).

Categories of toxic substances]:

Some organic compounds, such as benzene, formaldehyde, etc.

Heavy metal ions are also toxic to the human body.

Accidental ingestion of heavy metal ions can detoxify by drinking a large amount of milk.

Of course, pesticides, rat poison are poisonous.

First, poisonous mushrooms.

Nearly half of the people in China are rural, and rural people generally have the tradition of picking mushrooms in the mountains to eat, and even many urban residents will go to the suburbs or mountains and forests to pick mushrooms to eat, so that not only can bring fun to life, but also can enjoy their own hands, abundant food and clothing, and there are hundreds of types of mushrooms, even farmers who live in mountain villages all year round are difficult to identify all poisonous mushrooms, people who accidentally eat poisonous mushrooms and lose their lives every year, and may even destroy a family, so like poisonous mushrooms, Foods such as sprouted potatoes are better not to eat if they are not very familiar.

Second, poisonous snakes.

After talking about food, there are also animals, which are generally around us, and the poisonous ones are none other than snakes. Relative to food, poisonous snakes can be avoided, early summer is the season of poisonous snakes, dark and humid environment will be a good place for poisonous snakes to hide, it should be noted that the grass flower beds on the side of the road are also the places where poisonous snakes hide, once people are bitten by poisonous snakes within a few hours if they do not get **, there will be life danger, and even many highly poisonous poisonous snakes bite people There is no way to heal, only one life, so we must be vigilant.

Thirdly, undercooked beans.

There are thousands of dangers in life, it is very likely that a careless can cause fatal danger, and for highly poisonous animals, food precautions must be had, for the diet of life must understand the correct way to eat, such things as beans must be fully cooked before eating.

Fourth, food desiccant.

In addition, the desiccant in the packaged food must be very careful, do not let the elderly and children eat by mistake, and animals with highly toxic can also be avoided, don't worry too much, life lies in the details, everything pays attention to the details to avoid tragedy.

Rat-poisoning strong; Also known as no rat life, four-two-four, three-step down, smell to death, chemical name: tetramethylenedisulfontetraammonia.

Red paraquat, whose chemical name is 1-1-dimethyl-4-4-bipyridine cationic salt, is a rapid herbicide with contact killing effect and systemic effect.

The common poisons are as follows: Methanol: methanol is mixed with industrial alcohol, which often causes people to be poisoned by mistake; hydrogen sulfide gas; carbon monoxide gas, coal gas; Mercury:

What's in the thermometer is mercury; Nitrite: If sodium nitrite looks the same as table salt, it is often used as salt by unscrupulous traders**; Nitrogen oxides: fossil fuel combustion, vehicle exhaust; Sulphur dioxide:

Burning fossil fuels produces; Lead: burns leaded gasoline; Aflatoxin: High in sprouted potatoes.
