If I inhale an excessive amount of lead powder, can I eliminate it myself? What are the dangers of l

It's bad for the stomach and can be eliminated by itself as long as your metabolism is good.

The damage of lead to the human body is mainly manifested in the nervous system, digestive system and blood system, most of which are chronic, mild poisoning, and the symptoms are relatively mild, and neurasthenia syndrome is common.

Common symptoms: 1Neurological symptoms:

In the early stage, neurasthenia syndrome, headache, dizziness, dreaminess, memory loss, fatigue, muscle and joint soreness appear. In severe cases, peripheral neuritis can occur, manifesting limb sensation and movement disorders, and in severe cases, toxic encephalopathy can occur, causing mental disorders.

2.Digestive symptoms: indigestion, epigastric discomfort after meals, belching, nausea, abdominal pain and so on may occur in mild poisoning.

When acute poisoning or chronic poisoning occurs in an acute attack, abdominal cramps can occur, and abdominal pain is mostly around the umbilicus or lower abdomen, and the pain is severe and unbearable during the attack, so it is called 'lead colic', and typical lead colic is rare at present. After exposure to lead, if the oral hygiene is not good, blue lines often appear on the edge of the gums, called lead lines, which are formed by the accumulation of fine particles of lead sulfide.

3.Hematologic symptoms: mainly anemia, usually hypochromic macrocytic or microcytic anemia, due to anemia and facial ** vasoconstriction, may appear pale, the so-called 'lead appearance'.

4.Other site lesions: Kidney damage may occur with lead poisoning, and in rare cases, protein, red blood cells, and casts may be seen in the urine.

It is often accompanied by high blood pressure. Female patients may have menstrual irregularities, miscarriages, and preterm births. Lead is a gray-blue metal with a melting point of 327 degrees, when heated to 400-500 degrees, the vapor of existing lead escapes, can quickly condense in the air, oxidized into the form of smoke and dispersed in the air, brought into the digestive tract, dissolved and absorbed.

Pencil leads do not contain lead, and its main component is graphite.

Because lead has black marks when writing on rocks or walls, it was used as a drawing and writing tool in ancient Greece and Rome. In ancient China, it was written on silk and paper, and if there was a mistake, it was corrected with lead powder, so the word pencil did exist in ancient texts, but it was different from modern pencils.

In the fifteenth century, graphite ore was discovered, and people at that time did not know the composition of graphite, so they called graphite (blacklead). Around 1492, people in England began to use pens made of graphite, called pencils. It wasn't until 1779 that scientists learned that graphite was a form of carbon.

It is made by grinding graphite into powder, mixing it with clay, and then pouring it into two semi-circular wooden tubes.

In order to meet various needs, the graphite and clay in the pencil refill can be mixed in a variety of different proportions, and the nature and use of the refill are also different depending on the mixing ratio. For example, the refill used for sketching should be softer and darker; The refills used by students for their homework should be stiffer and lighter in color. When we buy a pencil, we should pay attention to the mark on the pen, where h stands for hard, f stands for firm, and b stands for bold.

According to the information provided by the manufacturer, the order of various pencils from soft to hard is as follows.

Lead is extremely harmful to the human body, it can affect the balance of excitation and inhibition of the cerebral cortex and directly damage peripheral nerves, causing dizziness, headache, weakness, muscle and joint soreness, sleep disorders, memory loss and other neurasthenia symptoms, and in severe cases, it will also lead to slowing down of sensory and motor nerve conduction velocity, limb numbness, sensory dullness, extensor muscle weakness, decreased grip strength and even paralysis in severe cases. If it affects the brain, there will be apathy, mental abnormalities, and motor disorders; In severe cases, coma, convulsions, vomiting, epileptic seizures, and brain damage syndrome appear.

In addition, lead can cause capillary damage and vasospasm. It leads to dysfunction and pathological changes of the nervous system, digestive system, blood system and kidneys, impairs renal function, and causes hypohemoglobin normal cell anemia.

Highly toxic. And it hurts a lot to **.

Lead smoke is the smoke that fills the air during the lead smelting process, generally in the form of lead dioxide. Lead dust is generally caused during processing and has relatively large particles. The damage to people is about the same. Easy to enter the bloodstream.

In order to effectively prevent lead dust damage, it is recommended to wear a KN100 dust mask.

Scientifically select dust masks to help prevent respiratory injuries.

Now masks must comply with the GB2626-2006 standard. The grades of dust masks are divided into three grades: KN100, KN95, and KN90. Among them, KN100 can achieve nearly 100% (more) protection effect against ultrafine dust.

The protective effect of dust masks depends on 2 aspects. One is the filtration efficiency of the filter cotton. The second is how tightly the mask is combined with the face.

Therefore, masks must be divided into large and small sizes, and the fit effect of masks and faces varies from person to person.

The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.

1. Choose a duplex half mask type. Disposable masks are not suitable for long-term protection due to their high air leakage rate.

2. Choose KN100 dustproof filter cotton for use. A low rate of protection will lead to physical injury.

3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.

4. Masks are divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.

5. There are two types of masks that cover the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable.

6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.

It's not good, and lead powder should be more harmful.

Among the many "culprits" that endanger human health and children's intelligence today, lead is one that is not insignificant. Many children now have higher levels of lead than young people. Traffic police officers are more exposed to lead poisoning than people in other professions.

After lead enters the human body, except for part of it is excreted through feces and sweat, the rest dissolves into the blood after a few hours, hindering the synthesis of blood, resulting in anemia, headache, dizziness, fatigue, drowsiness, constipation and limb aches.

Some have a metallic taste in the mouth, and symptoms such as arteriosclerosis, peptic ulcers, and fundus hemorrhage are also associated with lead contamination. In children, lead poisoning causes developmental delay, loss of appetite, difficulty walking, constipation, and insomnia; If you are an elementary school student, it is accompanied by hyperactivity, hearing impairment, inattention, mental retardation, etc.

This is because lead enters the human body and invades the nerve tissue of the brain through the blood, making nutrients and oxygen insufficient, resulting in brain tissue damage, which may lead to lifelong disability in severe cases.

In particular, children are in the stage of growth and development, and are more sensitive to lead than adults, and the lead entering the body has a strong affinity for the nervous system, so the absorption of lead is several times higher than that of adults, and the damage is particularly serious. If lead enters the body of a pregnant woman, it will pass through the placental barrier, affect the development of the fetus, and cause malformations.

Sexual taste is sweet, cold, and poisonous. Lead powder is a cosmetic product that used to be applied to the face to have a whitening effect. Also, in the past, there was ** shoe white powder on the market, which was specially used to whiten the surface of white running shoes. Lead is a metallic substance, and you say that it is not poisonous to eat it.

Eating more pig blood and duck blood is good for the discharge of brush hair and pencil powder, detoxification and beauty.

Lead poisoning can also affect the next generation of newborns, who can also become sick.
