Of the chemical elements in 109, 83 are metals, and metals with a density above 5 are collectively referred to as heavy metals. Heavy metals such as lead, cadmium and arsenic are very harmful. Once they enter the human body, it is a very slow process to be discharged. If you smoke 20 cigarettes a day, on average, your body will absorb 3.2 micrograms of cadmium a day, which is not enough to show symptoms immediately.
Heavy metals cause many diseases and may also cause cancer. Heavy metals may cause various diseases, such as hypertension and cardiovascular and cerebrovascular diseases caused by cadmium; Destroy bones, liver and kidneys, causing renal failure; Lead is one of the most toxic heavy metal pollution, and it will be difficult to eliminate once it enters the human body. It can directly harm human brain cells, especially the nervous system of the fetus, and can cause congenital mental retardation. Arsenic is one of the components of arsenic, which is highly toxic and will lead to rapid death. Long-term exposure to a small amount can lead to chronic poisoning. And carcinogenicity. Any of these heavy metals can cause headache, dizziness, insomnia, forgetfulness, mental disorders, joint pain, stones and cancer. It is worth mentioning that heavy metals in second-hand smoke are also very harmful.
Question 2: What causes heavy metals to exceed the standard? Heavy metals in various chemical states or forms will remain, accumulate and migrate after entering the environment or ecosystem, causing harm. For example, heavy metals discharged with wastewater can accumulate in algae and sediments even if the concentration is very small, and are adsorbed by fish and shellfish, resulting in food chain concentration, thus causing public hazards. For example, Minamata disease in Japan is caused by the transformation of mercury in wastewater discharged from caustic soda manufacturing industry into organic mercury through biological action; Another example is pain, which is caused by cadmium discharged from zinc smelting industry and cadmium electroplating industry. Lead emitted by automobile exhaust enters the environment through atmospheric diffusion and other processes, which leads to a significant increase in the current surface lead concentration, which makes the absorption of lead by modern people increase by about 100 times compared with that of primitive people, which is harmful to human health. Heavy metals do great harm to human body. Common ones are:
Children injured by heavy metal pollution
Mercury: It sinks directly into the liver after ingestion, which is extremely harmful to the brain, nerves and vision. Natural water contains 0.0 1 mg per liter of water, which will cause human poisoning.
Cadmium: causes hypertension and cardiovascular and cerebrovascular diseases; Destroy bones, liver and kidneys, leading to renal failure.
Lead: It is one of the most toxic heavy metal pollution. Once in the human body, it is difficult to eliminate. It can directly harm human brain cells, especially the nervous system of the fetus, and can cause congenital mental retardation.
Cobalt: It can cause radiation damage to the skin.
Vanadium: It hurts the heart and lungs and causes abnormal cholesterol metabolism.
Antimony: With arsenic, silver jewelry will turn brick red and be radioactive to the skin.
Thallium: It can cause polyneuritis.
Manganese: Too much will make people hyperthyroidism. It can also damage vital organs.
Arsenic: As a component of arsenic, it is highly toxic and can lead to rapid death. Long-term exposure to a small amount can lead to chronic poisoning. And carcinogenicity.
Any of these heavy metals can cause headache, dizziness, insomnia, forgetfulness, mental disorders, joint pain, stones and cancer.
In recent years, heavy metal pollution incidents are common, ranging from excessive blood lead of children in Hunan, excessive blood lead of hundreds of children in Fengxiang, Shaanxi, to heavy metal pollution "vegetable basket". Recently, it has been reported that there is heavy metal pollution in drinking fountains, which shows that heavy metal pollution has affected our living environment. Our common plastic doors and windows are also polluted by heavy metal lead. Plastic doors and windows belong to PVC profiles, and the heat stabilizer system of PVC profiles mainly includes lead salt, organotin, calcium and zinc and their composite stabilizers. Lead salt stabilizer has become the most widely used stabilizer in the production of plastic doors and windows in China because of its good stabilizing effect. However, due to the toxicity of lead, although it is not in direct contact with human body, it still poses a threat to the environment and human health. In North America, lead stabilizers are not allowed for hard PVC doors and windows. Health Canada document 1996-48, the United States Consumer Product Safety Commission document 96- 150 and document 4426 all clearly stipulate this. However, the pollution problem of lead salt stabilizer has not been paid attention to in China.
Question 3: I checked my body for excessive heavy metals today. What does heavy metal mean?
lead to
chrome
manganese
Mercury
Question 4: What does heavy metal pollution mean? Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds. It is mainly caused by human factors such as mining, waste gas emission, sewage irrigation and excessive use of heavy metal products. Due to human activities, the content of heavy metals in the environment has increased beyond the normal range, which directly harms human health and leads to the deterioration of environmental quality.
Question 5: What is heavy metal exceeding the standard, and how serious the harm can be to people, which will lead to the imbalance between other trace elements and the brain. Vanadium and antimony can cause renal failure, especially calcium; It will cause dementia to the elderly. It can cause numbness of limbs: it is a kind of toxic heavy metal pollution, which can cause great visual damage and hemolysis. Cadmium can cause abnormal cholesterol metabolism. 0 1 mg: cause abnormal blood circulation system. Take the lead. It can also rupture red blood cells: arsenic can turn silver ornaments into brick red, which will cause rapid death, and excessive iron will destroy the basic components of cells. And cancer and nerves. Manganese. Cobalt, anemia, nucleic acid, etc. ; Damage to bones, liver and kidneys, such as fatty acid F: damage to the heart and protein, will be difficult to rule out mutagenicity once it enters the human body. It can also damage bones and is very toxic. Tin. Arsenic, liver: zinc fever, kidney. It will also harm the liver and kidney: it is one of the components of arsenic, and it is mentally abnormal. It will also harm important organs and the demand for magnesium: it will cause polyneuritis: it will sink directly into the liver if eaten; Can lead to high blood pressure; It will cause radioactive damage to the skin; It can catalyze oxidation in human body, leading to chronic poisoning. The harm of chromium heavy metals to human body is enormous. It can directly harm human brain cells and cause cardiovascular and cerebrovascular diseases: mercury. Zinc has radioactive damage to the skin, and each heavy metal does harm to the human body in different ways: excessive zinc will make people hyperthyroidism. Natural water contains 0 per liter of water, which can cause congenital mental retardation and lead to poisoning. There is also carcinogenicity, especially for the nervous system of the fetus. Thallium. Iron. Long-term exposure to small amounts
Question 6: How to deal with five sources and solutions of heavy metals exceeding the standard?
1, seafood seafood is the star of healthy recipes. It is delicious and nutritious, and can prevent cardiovascular diseases and improve mood and memory. At the same time, the safety of seafood can not be ignored. Due to the spread of pollution, shellfish and marine fish have become the largest sources of heavy metals such as mercury and arsenic, so if you eat seafood for a long time, it will lead to the accumulation of toxic and harmful substances such as heavy metals in your body and endanger your health.
Avoidance method: the quantity cannot exceed100g; Try to eat little seafood. Large seafood is at a higher stage of the food chain and contains more pollutants. Do not eat or eat less fish head, skin, fish oil, viscera, fish eggs and shark fins.
Chinese medicine has always been known for its gentleness and little side effects. So some people take Chinese medicine as a daily supplement and eat nothing. And some Chinese medicines aim at fighting poison with poison, but their toxicity is low. For example, realgar and cinnabar, which are common in traditional Chinese medicine, contain mercury and arsenic. Long-term use of cinnabar and realgar will lead to the accumulation of heavy metals such as mercury and arsenic in human body, causing serious liver and kidney damage, and
How to avoid it: Even if it is a mild Chinese medicine, you should consult a doctor before taking it to determine whether it is suitable for your own physique and symptoms, and the longest time you can take it, so as to give full play to its efficacy correctly and avoid improper use.
3. Although the internal organs of animals have unique nutrients, more heavy metals are deposited. Because poultry are fed with industrial feed, these feeds are uncertain. Once unsafe food is eaten by animals, such as animal feed, if drinking water is polluted by heavy metals such as cadmium, it will inevitably undergo metabolism in internal organs, and some harmful substances such as heavy metals will be deposited in internal organs. The Health Department of Hubei Province has published the monitoring situation of food pollutants in Hubei Province. The cadmium content exceeds the national standard value 100 times. In addition to cadmium, animal viscera may also contain lead, and those heavy metals left in viscera will be transferred to you and become your health killer.
How to avoid it: and don't eat more than 50 grams at a time. In addition, when eating animal offal, it is best to add coarse grains and vegetables to supplement dietary fiber.
4. preserved eggs when making preserved eggs, there is an auxiliary material wrapped outside the fresh eggs, called Mimo Monk. Its chemical composition is lead oxide. Adding lead oxide can promote the ingredients to penetrate into eggs evenly and quickly, and also can make preserved eggs solidify quickly and shell easily. However, in the process of placing, these lead oxides gradually penetrated into the eggs.
How to avoid it: you can recognize the label and choose lead-free preserved eggs; Add some vinegar when eating preserved eggs. Acidic substances can minimize the body's absorption of toxic substances.
5. The can is made of aluminum alloy, and the inner wall of the can is coated with an organic coating to isolate the aluminum alloy from the beverage. Some unqualified aluminum cans are probably not coated with protective coating in some places during processing, or coated too thin, which leads to the contact between aluminum alloy on the inner wall of the cans and drinks. As time goes on, aluminum gradually melts into it, especially when the beverage in the can is acidic or alkaline. According to the researchers' investigation of 22 kinds of drinks, cans are more harmful.
Avoid: drinking bottled drinks or simply drinking boiled water in your own cup is healthier.
