What is the reaction of heavy metal poisoning?
summary
Heavy metal poisoning refers to the poisoning caused by heavy metal elements or their compounds with relative atomic mass greater than 65, such as mercury poisoning, lead poisoning, etc. Because heavy metals can irreversibly change the structure of proteins, thus affecting the function of tissues and cells, thus affecting human health. For example, enzymes in the body can not catalyze chemical reactions, carriers on the surface of cell membrane can not transport nutrients and discharge metabolic wastes, and myosin and actin can not complete muscle contraction, So the cells in the body can't get nutrition, get rid of waste, produce energy, and the cell structure collapses and functions lose. So what's the response to heavy metal poisoning? Here are some heavy metal reactions.
What is the reaction of heavy metal poisoning?
Manganese（ 1) Acute poisoning inhalation of manganese oxide dust is likely to produce the so-called metal fumigation heat or chemical pneumonia, manganese oxide is often produced by welding or cutting manganese. Chills, fever, nausea and coughing all occur（ 2) Chronic poisoning is mainly caused by neurological and mental abnormalities, which can be divided into three stages: ① early stage - cognitive impairment and emotional distress, including anorexia, myalgia, neuroticism, restlessness, uncontrollable violence, insomnia, decreased sexual desire. ② Medium term - uncontrollable crying and laughing, speech disorders, visual hallucinations, clumsy movements, confusion of consciousness. ③ Later stage - walking difficulties, stiffness, inability to speak, shaking, similar to Parkinson's disease.
Nickel（ 1) Acute poisoning (1) is usually caused by inhalation of organic nickel. The symptoms of poisoning are similar to carbon monoxide poisoning, but accompanied by the rise of blood sugar and urine sugar; Often nausea, vomiting, headache, dizziness, insomnia, restlessness, lasting for several hours. Then there will be pneumonia like chest tightness, dyspnea, cough, palpitations, sweating, weakness and blurred vision. ② Bivalent inorganic nickel poisoning: it is caused by drinking nickel contaminated drinking water or dialysis water by mistake. Its symptoms are nausea, vomiting, headache, palpitation, weakness, diarrhea, shortness of breath, cough, etc（ 2) Chronic poisoning, long-term skin contact will have allergic dermatitis, in addition to chronic respiratory diseases, immune dysfunction and cancer can occur. Common in electroplating industry.
Lead（ 1) Acute poisoning (adults) ① mild and moderate poisoning, fatigue, restlessness, paresthesia, myalgia, abdominal pain, shaking, headache, nausea, vomiting, constipation, weight loss and decreased libido. ② Severe poisoning, motor neuropathy, brain disease, convulsion, coma, severe abdominal colic, acute renal failure（ 2) Chronic poisoning (1) central nervous brain disease, mental and intellectual disorders, neurobehavioral abnormalities, affect the development, development and IQ of children. ② The motor nerve conduction velocity of peripheral nerve became slower. ③ Blood anemia, hemolysis, etc. ④ Renal hypertension, gout and chronic renal failure. ⑤ Others interfere with vitamin D metabolism, reduce sperm motility and number, carcinogenicity and so on.
matters needing attention
As an individual, it is very important to strengthen prevention and self-protection. First of all, do not use lead containing materials for eating utensils. It is better not to use colored glazed ceramic products to hold acidic food and drinks; Try not to go to the streets or highways with heavy traffic and lead pollution, especially children. Don't suck gasoline with your mouth. Keep a certain distance from the car in front of you. On the crowded road, you'd better close the window; Traffic police, car repair workers and gasoline station workers should take a bath and change clothes in time after work, and regularly go to the hospital for examination, so as to find out and treat in time.
