I often see people asking “what is the hazard of excessive lead in faucets?” In order to satisfy everyone’s curiosity and let everyone know more about healthy living, the editor will introduce the hazards of lead poisoning to you today. What are the sources and causes of lead poisoning? What are the symptoms of lead poisoning? What is the harm to the human body if the tap exceeds the standard?
Causes and sources of “lead poisoning”
There are many reasons for lead poisoning. Eating lead-containing foods, such as preserved eggs, popcorn, lead solder canned food, fruit peels, आदि; frequent contact with color-printed food packaging, paints, lead-containing cosmetics, hair dyes, and lead-contaminated products Clothing, car exhaust, lead-containing drugs; light lead-containing candles, especially scented and slow-burning candles.
There are usually two sources of lead in the human body: one is diet, and the other is the atmosphere. The main ways lead enters the human body are: respiratory tract, digestive tract and skin. The lead content in the normal atmosphere is very small, but the lead concentration can reach 1-8ug/m3 in large industrialized cities, especially in some industrial areas and traffic congested areas, the lead concentration is even higher. Lead and lead compounds in the atmosphere enter the human body mainly from the respiratory tract.
What are the symptoms of “lead poisoning”?
After lead enters the human body, except part of it is excreted through feces and sweat, the rest dissolves into the blood after a few hours and hinders the synthesis of blood, leading to anemia, headache, dizziness, fatigue, drowsiness, constipation, and sore limbs; some There is a metallic taste in the mouth, and symptoms such as arteriosclerosis, gastrointestinal ulcers and fundus bleeding are also related to lead contamination.
What are the symptoms of “lead poisoning”?
Lead poisoning can affect many organs of the human body. Its manifestations include nausea, vomiting, loss of appetite, abdominal distension, constipation, blood in the stool, abdominal cramps, dizziness, restlessness, insomnia, drowsiness, irritability, pale complexion, palpitations, shortness of breath, Low back pain, edema, proteinuria, hematuria, tubular urine, and severe renal failure may occur. If a pregnant woman is accidentally lead poisoned during pregnancy, it can also cause miscarriage, stillbirth, or deformity.
The harm and influence of “lead poisoning” on children
Some experts used the Japanese SM Social Life Ability Scale (revised version) to investigate children. The scale includes six areas of independent living ability, athletic ability, work ability, communication ability, collective living ability, and self-management ability. The results show that Social viability and blood lead levels are very significantly negatively correlated, strongly revealing that lead poisoning seriously damages children’s social viability. The **new international research shows that IQ is the basis of success, and social quotient (EQ) is the key to success.
Lead poisoning in children can cause developmental delay, loss of appetite, and inconvenience in walking. If it is a primary school student, it is also accompanied by hyperactivity, hearing impairment, inattention, and mental retardation. This is because lead enters the human body and invades the nerve tissue of the brain through the blood, resulting in insufficient supply of nutrients and oxygen, causing brain tissue damage. In severe cases, it may lead to lifelong disability. Especially when children are in the stage of growth and development, the lead that enters the body has a strong affinity for the nervous system, and the damage is particularly serious.
Harm 1: damage to the nervous system
Pencils are something that everyone will come into contact with. यद्यपि, adults always tell us that we can’t bite pencils with our mouths. The most important reason is that lead can damage the human nervous system, reduce memory, vision, and intelligence, and Frequent symptoms such as fatigue, headache, irritability, and insomnia seriously affect people’s normal life.
Harm 2: Inducing anemia
Anemia is a very common event for people nowadays, and a large part of the reason is that we have long-term consumption of lead, which inhibits the synthesis of heme, which makes people lack of iron, zinc, and calcium.* *Eventually lead to anemia, and if you continue to consume lead, your condition will worsen dramatically.
Harm three: cause hypertension and arrhythmia
When lead poisoning is severe, the tension and tension of blood vessels will increase sharply, which will cause people to suffer from diseases such as high blood pressure and arrhythmia. We all know that once they have these two diseases, it is difficult to cure, and drugs must be used to control the disease. त्यसैले, the harm to people is great.
Harm four: affect the normal development of children
We all know that children’s resistance is relatively weak, and children who have been exposed to lead for a long time are prone to nephritis. त्यसैले, generally only first grade students will use pencils. Once they suffer from nephritis, it will reduce the clearance of the kidneys, thus It will harm other body organs and seriously affect the normal development of children.
Harm five: reduce immunity
Lead will combine with the antibodies in the human body to reduce human resistance, so that people are susceptible to other viruses or bacteria infections, especially easy to cause repeated infections of the respiratory tract and intestines, and bring unimaginable harm to human health. In severe cases, it will also affect the secretion of many important hormones, resulting in unimaginable consequences.
