The standard for different degrees of lead poisoning is fast

Hello, the criteria for lead poisoning are as follows:

Grade: blood lead 10 g dl, relatively safe (existing embryonic development toxicity, pregnant women are prone to miscarriage);

Grade: blood lead 10-19 g dl, impaired penterythrin metabolism, decreased nerve conduction velocity;

Grade: blood lead 20-44 g dl, iron, zinc, calcium metabolism is affected, calcium deficiency, zinc deficiency, hemoglobin synthesis disorders, there may be symptoms such as low immunity, learning difficulties, poor concentration, decreased IQ level or physical growth retardation;

Grade: blood lead 45-69 g dl, can have variable personality, irritability, hyperactivity, aggressive behavior, motor disorders, vision loss, unexplained abdominal pain, anemia, arrhythmia and other poisoning symptoms;

Grade: 70 g dl of blood lead, which can lead to renal impairment, lead encephalopathy (pain, convulsions, coma, etc.) and even death.

At present, there is no targeted standard for lead contamination in water, thank you

Level I: <

IIA: IIIB:

Level III: Level V:

Grade I is a safe blood lead level, and II V has different degrees of lead poisoning Grade I-III blood lead level table, which should be rechecked every 3 months, and at the same time, pay attention to eating less lead-containing foods (such as dried rice, baked potato chips, etc.), avoid contact with lead-containing things, stay away from lead-contaminated places, eat more foods rich in vitamin C, eat more calcium-containing and iron-containing (such as fish, meat, eggs, blood, liver, black fungus), zinc-containing foods (meat, seafood) and pectin-containing foods such as oranges, carrots, apples, bananas, etc. Grade V, please go to the pediatric hospital immediately for lead removal treatment, and use drugs to drive lead.

Currently, developed countries have lowered the diagnostic criteria for lead poisoning in children to 60 ug l.

Hyperleademia: two consecutive venous blood lead levels of 100 199 mg L;

Lead poisoning: two consecutive venous blood lead levels equal to or higher than 200 mg L; It is classified into mild, moderate, and severe lead poisoning according to blood lead levels.

Mild lead poisoning: blood lead level is 200 249 mg l;

Moderate lead poisoning: blood lead level is 250 449 mg l;

Severe lead poisoning: blood lead level equal to or higher than 450 mg L;

Lead poisoning in children can be accompanied by some non-specific clinical symptoms, such as vague abdominal pain, constipation, anemia, hyperactivity, impulsivity, etc.; When blood lead is equal to or higher than 700 mg L, it may be accompanied by coma, convulsions and other manifestations of lead poisoning encephalopathy.

There are many ways to excrete lead, and dietary therapy can be used as a preventative measure, which can block some external lead absorption and partially excrete lead from the blood. But nutrient interventions are the safest for children. It is best to use the only lead removal oral solution approved by the Ministry of Health of the People's Republic of China with the function of "promoting lead removal and enhancing immunity".

Yitong Growth Lead Removal Oral Liquid is good! It is a health supplement that promotes lead removal and strengthens immunity. Non-toxic***.

Only the combination of lead removal and strengthening the body is the symptom and the root cause, so taking lead removal oral liquid is really useful. Because Yitong Growth Oral Liquid can also supplement trace elements such as zinc while removing lead, long-term use is very helpful for children's growth and development.

Question 1: What kind of harm does lead poisoning cause to the human body? It is understood that lead is a toxic heavy metal, and a large amount of lead smoke will escape when heated to 400 500.

The vapor, smoke and dust of lead and its compounds mainly invade the human body through the respiratory tract, which is the main invasion route of occupational lead poisoning, and can also be absorbed through the digestive tract.

For people who are not exposed to lead, such as children, lead poisoning may be caused by licking a mother's face with lead, sucking on a lead-based ointment that has been applied to the mother's **, and the breast milk of a mother who has lead poisoning. When children erupt in baby teeth, they often like to chew on lead-containing paints such as bed frames and toys and cause poisoning.

An expert from an occupational disease hospital in Shandong Province said; The main hazard of lead poisoning is to the nervous system. Patients mainly present with neurasthenic syndrome, which may include headache, dizziness, fatigue, memory loss, insomnia, dreaminess, irritability, etc.; In peripheral neuropathy, the main manifestations are joint pain with distal limb gloves and sock-like superficial sensory impairment, and in severe cases, it is manifested as "lead paralysis", or "hanging wrist" due to extensor weakness, mostly focusing on the hands, and "hanging feet" is rarely clinically rare; Severe cases of toxic encephalopathy may have severe headache, vomiting, blurred vision, mental depression or mania, obsessive-compulsive delusions, hallucinations, delirium, varying degrees of impaired consciousness or epileptiform convulsions, cerebral edema, increased intracranial pressure, etc., and a small number of patients may have optic edema, cerebrospinal fluid examination, mildly elevated white blood cells, increased protein, etc.

Another harm of lead poisoning is the digestive system, which can manifest as loss of appetite, nausea, dull abdominal pain, bloating, diarrhea or constipation. In severe cases, abdominal colic may occur, mostly sudden, often around the umbilicus, when the patient is pale, irritable, cold sweat is frequent, * curly, the attack can last for more than a few minutes. On examination, the abdomen is usually flat and soft, mildly tender but not fixed, and bowel sounds are diminished.

A small number of patients may have hepatomegaly, but liver function is usually unabnormal.

In addition, lead poisoning can affect the blood and hematopoietic system, as well as the kidneys. Patients may have mild anemia, usually hypochromic normocytic anemia. Patients with renal impairment have aminoaciduria, glycosuria, and phosphateuria; A small number of patients with severe disease may develop proteinuria, with decreased urine red blood cells, casts, and renal function.

Experts also said that once you find yourself or someone around you has symptoms of poisoning, you should go to a regular hospital for medical treatment in time.
