Is lead poison harmful to the human body? How harmful is lead poisoning to the human body

Meng Xinbao parents should know, the dangers of lead poisoning!

Harm. Lead is very harmful and is a highly toxic substance. At the same time, it is a heavy metal that seriously endangers human health.

The biggest feature of lead poisoning is non-specific, not easy to attract people's attention, after the human body inhales or eats, it will eventually form lead accumulation in bones, hair, teeth, etc., when the accumulation reaches a certain amount, it will cause fatigue, headache, sleep disorders, abdominal pain, and will also lead to an increase in the concentration of uric acid in blood and urine, causing joint and kidney damage.

At the same time, if the human body ingests excessive lead, it will damage the human nervous system, heart and respiratory system, reduce people's concentration, and can have a greater impact on people's hematopoietic function, digestive function and reproductive function.

The harm of lead poison to the human body is huge, and it can enter the human body through a variety of ways, causing serious toxic damage to the human body. Lead poison can enter the human body through breathing, food, water and other ways, and after entering the human body, lead poison will be deposited in the blood, liver, kidneys, bones and brain and other organs, and enter the whole body through blood circulation, causing toxic damage to the human organs.

The toxic damage of lead poisoning to the human body is mainly manifested in neurotoxicity, blood toxicity, renal toxicity, liver toxicity, etc. The toxic damage of lead poison to the nervous system is mainly manifested as headache, nausea, vomiting, nervousness, insomnia, memory loss, etc. The toxic damage of lead poisoning to the blood system is mainly manifested as anemia, coagulation dysfunction, thrombocytopenia, etc. The toxic damage of lead poisoning to the kidneys is mainly manifested as renal failure, proteinuria, and hematotoxic nephritis. The toxic damage of lead poisoning to the liver is mainly manifested in liver failure, liver cirrhosis, hepatitis, etc.

In order to prevent the harm of lead poisoning to the human body, we should pay attention to the following points: first, avoid contact with the environment contaminated by lead; the second is to avoid eating lead-contaminated food; the third is to avoid drinking lead-contaminated water; Fourth, pay attention to food hygiene and avoid eating rotten food; Fifth, pay attention to wearing protective equipment and avoid contact with lead-contaminated items; Sixth, pay attention to labor protection and avoid contact with lead-contaminated items.

Lead is a toxic heavy metal element that does not have any physiological effect in the human body, so the ideal blood lead concentration should be zero, however, due to the prevalence of lead in the environment, many people may be attacked by lead, so what is the harm of lead to the human body? 1 How harmful is lead Lead is one of the most toxic and cumulative heavy metal elements known to the world, and the impact of lead on the body is systemic and multisystemic. It can accumulate in the body for a long time, which can seriously harm the nervous system, hematopoietic system and digestive system, and has a particularly serious impact on the intelligence and growth and development of infants and young children.

2 The harm of lead to the nervous system Lead can cause damage to the nervous system through the blood-brain barrier, and this damage is often irreversible. Mild cases may cause hyperactivity, attention deficit, easy agitation, unresponsiveness, drowsiness and motor disorders, and severe cases may lead to sequelae such as intellectual disability, cerebral palsy, blindness and abnormal behavior. 3. The harm of lead to the digestive system Lead can destroy the regeneration ability of the gastric mucosa, causing inflammatory changes in the gastric mucosa.

People with lead poisoning will have digestive manifestations such as loss of appetite, nausea, vomiting, abdominal pain, constipation, diarrhea, and in severe cases, lead colic. 4. Lead toxicity to the liver In acute lead poisoning, lead can directly damage liver cells, and make intrahepatic arteriolar spasm cause ischemia, and acute lead toxicity liver disease occurs, causing hepatomegaly, abnormal liver function, etc., lead can also make the liver cytochrome system dysfunction. In addition, the former can also alter many biochemical generations of the liver.

Lead poisoning is very harmful to health, lead poisoning is mainly high in children and adolescents, mainly affecting physical development, resulting in brain injury, mental decline and inability to develop, I will take you to understand.

Lead poisoning will endanger all the normal growth and development of children, not only will harm various human organs, but also seriously endanger the growth and development of children's central nervous system, irreparable harm to children's minds, and will also harm children's brain development.

The most painful thing is that even if the child is guided in various ways, the harm caused by lead poisoning is still unavoidable. Because the development of lead poisoning is relatively slow, the manifestations of poisoning are relatively hidden, and it is very easy to be confused with other common diseases in children. Therefore, parents often ignore the specific situation of the baby's poisoning and cannot deal with it in time.

Therefore, parents should pay attention to such "original perpetrators of children".

Don't go to areas with high lead content: Don't take your children to roads with heavy traffic, try to plant greenery in relatively wide areas to reduce lead intake.

Develop a good habit of cutting off your baby's fingernails often, as nails are likely to be polluted by the environment and are very prone to lead retention. In daily life, children are required to develop a reasonable habit of scolding their hands.

Frequent handwashing is crucial. When your child eats his hands or eats other objects, it is important that he guides him early and accurately to prevent bad habits of eating and eating. Baby toys, especially those that fit in your mouth, should be cleaned up frequently.

Maintain food hygiene and safety: Fruits and vegetables must be cleaned before application. When eating apples, disconnect the skin as much as possible and hand it over to your baby.

There is no need to eat leaded ingredients, Ye Chunhui raw eggs, popcorn corn and other ingredients with high lead content to avoid the opportunity for children to eat.

Arrange your baby's balanced diet scientifically: Make sure you get enough calcium, iron, selenium, zinc and magnesium in your daily diet. The natural environment should be cleaned up by the natural environment: when the old house is renovated, environmentally friendly heavy metal-free raw materials should be used to reduce the lead environmental pollution in the home.

1. Hinder the growth and development of children, damage various organs 2. Damage children's brains, lead to learning disabilities, language disorders, and directly affect IQ 3. Adverse consequences such as miscarriage and underweight of newborns after lead poisoning in pregnant women.

There is a great danger to health, it is likely to cause poisoning, and then it is also very likely to cause slowdown of blood flow, and it may also lead to syncope and shock.

It can affect the nerves, affect the digestive system, and also affect the cardiovascular and cerebrovascular vessels, which can cause kidney damage, and can also lead to anemia.

It can lead to contagious chronic diseases, which can affect intelligence, cranial nerves, cardiovascular disease, organ failure, and cancer.

There will be poisoning, and it will also cause some damage to the kidneys, including the heart, and it is very likely that you will fall unconscious, and in severe cases, you will die.

Among the many "culprits" that endanger human health and children's intelligence today, lead is one that is not insignificant. According to authoritative survey reports, the average amount of lead in the modern human body has greatly exceeded 500 times that of the ancients 1,000 years ago! However, human beings lack active and effective protective measures.

According to surveys, the average body content of many children is generally higher than that of 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 soreness. 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.

Oral administration of 2-3 grams of lead can cause poisoning, and 50 grams of lead can be fatal. Clinical lead poisoning is rare.

Clinical manifestations of lead poisoning:

1.abdominal pain, diarrhoea, vomiting, black stools;

2.headache, dizziness, insomnia, and even irritability and coma;

3.palpitations, pallor, anemia;

4.vasospasm, liver and kidney damage;
