There are three kinds of air pollution sources: first, domestic pollution sources, which are pollutants discharged into space when urban and rural residents need daily life and cooking, heating, bathing and other service industries burn various fuels; Second, industrial pollution sources, industrial and mining enterprises and other pollutants discharged into space in various life activities; Third, traffic pollution sources, such as exhaust gas and other pollutants discharged into space by vehicles and other vehicles.
The main pollutants in the air are carbon monoxide, hydrocarbons, sulfur dioxide, lead, ozone and various suspended particles. Carbon monoxide is a colorless and odorless toxic and deadly gas, which can be released together with automobile exhaust. In closed areas such as places with dense traffic, intersections, garages and tunnels, the content of carbon monoxide is extremely high. The main hazards of carbon monoxide are reducing the oxygen transmission of red blood cells, losing the function of brain and heart, and other damages to hearing, vision and thinking. However, we need to make joint efforts to completely improve the air quality in China, prevent environmental pollution, maintain ecological balance, restore people's natural state of fresh air and ensure the healthy development of human society. However, when the harmful air and toxic pollution sources have not been completely eliminated, for the sake of health and disease prevention, we should know some methods of detoxification and antivirus, so that the harmful and toxic substances inhaled can be discharged from the body in time and effectively, so that we can live and work healthier.
2. Toxins from unclean water sources
Water is the source of all life. Water is an indispensable and important substance in human life activities. About 65% of human tissues are composed of water, and 80% of blood is water. Water is a solvent for many substances. In the whole life process, water circulates all the time, transporting amino acids, glucose, lipids, vitamins, hormones, enzymes, oxygen and other essential nutrients to the whole body, supplying various cell tissues, and taking away many metabolic wastes and toxins, such as carbon dioxide, urea, uric acid, creatinine, etc., and discharging them through the lungs and kidneys. Water also plays a role in regulating body temperature. Only by taking away heat through sweat and involuntary water evaporation can the body temperature be kept at around 37 degrees. Water can also lubricate tissues and cells, the water in the orbit can lubricate the eyeball, saliva and gastric juice can help swallow and digest food, the lungs are moist, so that people can breathe, and the joint cavity is moist, so that people can move freely.
Like air and food, water is an indispensable substance in life activities. Without water, the human body will be poisoned by its own waste. When the kidney excretes uric acid, the metabolites must be dissolved in water. If the human body doesn't have enough water, waste and toxins can't be effectively excreted, some substances will accumulate to form kidney calculi, and even faint due to dehydration. It can be seen that water plays a very important role in maintaining human life.
Water pollution is mainly caused by domestic sewage and industrial wastewater. Domestic sewage, wastewater from food processing and paper industry are rich in carbohydrates, protein, oil, lignin and other organic substances. They exist in suspended or dissolved state in sewage and are decomposed by microorganisms, and oxygen is consumed in the process of decomposition, which is called aerobic pollutants. If such pollutants are discharged into the water body too much, it will reduce the dissolved oxygen in the water and directly affect the growth of aquatic organisms such as fish. When the dissolved oxygen in the water is exhausted, the organic matter will undergo anaerobic decomposition, producing substances with unpleasant smell such as hydrogen sulfide and ammonia, which will make the water black and stale. Domestic sewage, wastewater from food, processing and papermaking industries often contain a certain amount of plant nutrients such as phosphorus and nitrogen; Farmland water and detergent sewage with phosphate fertilizer and nitrogen fertilizer also contain a lot of phosphorus and nitrogen, which will cause eutrophication of water sources. Plankton, such as algae, proliferates in large quantities, and after death, it is decomposed by aerobic microorganisms, consuming dissolved oxygen in water, or decomposed by anaerobic microorganisms, constantly producing gases such as nitrogen sulfide, which will worsen water quality.
Water is the source of all life, and its quality is closely related to people's health and longevity. Water polluted by chemical poisons can cause acute and chronic poisoning after being drunk by human body. Drinking low-concentration phenol-containing water for a long time can cause dizziness, insomnia, anemia, memory loss, rash, itching and other chronic poisoning symptoms. If the water quality is polluted by polycyclic aromatic hydrocarbons such as arsenic, chromium, nickel, aniline and benzopyrene, drinking water containing these substances for a long time may induce cancer. If the water quality is polluted by pathogenic microorganisms, it may cause dysentery, typhoid fever, cholera, infectious hepatitis, ascariasis, schistosomiasis, amebic dysentery and other diseases.
At present, the water quality has not been effectively improved, and harmful and toxic pollutants have not been completely removed. In order to prevent diseases, we should know some methods of detoxification and antivirus. Usually eat more fruits and vegetables that detoxify, so that harmful and toxic substances that enter the human body can be excreted in a timely and limited manner, in order to live a long and healthy life.
3. Toxins in the living room
According to authoritative investigation, nearly 500 kinds of volatile noodles have been detected in the air, and the harmful substances in indoor air are dozens of times higher than those outside. People spend most of their lives indoors, and poor ventilation, decoration pollution, electromagnetic pollution and air pollution may all induce cancer.
1) Poor ventilation. Old houses, mostly civil structures, have rafters and tiles on the roof, which are breathable. There is a gap between the rafters and the horizontal dye, and air can pass freely. At present, reinforced concrete and aluminum alloy doors and windows are poorly decorated, especially in high-rise buildings in downtown areas. The doors and windows are closed all the year round, just like a cement tank, which will inevitably lead to poor indoor ventilation. It is conceivable that people have lived in such an environment for a long time, and it is not surprising that sub-health reactions such as dizziness, brain swelling, chest tightness and fatigue appear over time. Therefore, we should consciously develop the habit of opening the window and opening the door for ventilation, even when using air conditioning, we should leave a gap to let the outdoor fresh air be replenished continuously.
2) Decoration pollution. Decoration pollutants are mainly divided into four types: formaldehyde, benzene, ammonia and radon. Among them, formaldehyde ranks second in the priority control list of toxic chemicals in China and has been identified as carcinogenic and teratogenic by the World Health Organization. Formaldehyde mainly comes from indoor building materials and furniture, such as plywood, particleboard, foam filler, wood floor, wallpaper, paint, coating and so on. Relevant data show that formaldehyde will be released slowly in newly renovated rooms in the next 5- 15 years. Long-term exposure to low-dose formaldehyde can cause various chronic respiratory diseases, reduce the memory and intelligence of teenagers, cause nasopharyngeal carcinoma, colon brain tumor, nuclear gene mutation, inhibit DNA damage repair, menstrual disorder, pregnancy syndrome, neonatal chromosome abnormality, and even cause leukemia. Among all the contacts, children, pregnant women and the elderly are particularly sensitive to formaldehyde, which is more harmful.
3) household appliances. According to the observation of medical scientists, the harm of electromagnetic radiation to human body is manifested in two aspects: thermal effect and non-thermal effect, both of which will increase oxygen free radicals in human body and induce cancer over time. According to the report of the authoritative Washington Office of Technology Assessment, electromagnetic waves generated by household appliances are harmful to human cells. For example, women who use electric blankets to sleep for a long time will change their menstrual cycle in addition to sub-health symptoms such as irritability, palpitation, listlessness and loss of appetite. Frequent use of electric stoves by pregnant women will increase the incidence of infant tumors. In order to prevent the harm of electromagnetic waves to human body, firstly, we should keep a certain distance from household appliances, and the farther the distance, the less electromagnetic waves will hurt us; Second, some household appliances that generate electromagnetism, such as radios, televisions and refrigerators. , should not be placed in the bedroom. If this is not possible, the quantity should be reduced as much as possible. Third, when using household appliances, we should observe whether there is electronic fog interference. Once found, it should be stopped immediately. In addition, use mobile phones as little as possible to avoid using all kinds of household appliances at the same time to prevent the formation of strong electromagnetic waves. At the same time, we should pay attention to nutrition, eat more fruits and vegetables with high vitamin A and vitamin C content, and reduce the harm of electromagnetic pollution to human body.
4) air pollution. It is observed that when cooking in the kitchen, the oil pan is heated to the boiling point (smoking), and the oil temperature can be as high as 280 degrees, which is easy to produce some strong carcinogens, which is an important factor that can not be ignored in female lung cancer.
4. Toxins in drugs
Some people blindly abuse tonics and tonics in order to preserve health and prolong life, or take drugs in excess, in excess and in excess in order to treat diseases, which will produce some toxic and side effects and endanger health. This is the truth that people often say, "Too much tonic becomes poison, and medicine is also poison".
Long-term medication and improper medication can lead to poisoning and malnutrition, which is called drug-induced malnutrition in medicine. Drugs can affect the absorption, synthesis, metabolism and excretion of some nutrients. In recent years. This kind of malnutrition is increasing year by year. For example, the secondary infection caused by long-term use of sulfonamides and some broad-spectrum antibiotics is to inhibit the growth of normal intestinal flora and make other pathogenic bacteria multiply and grow; Normal flora has the function of helping the body to synthesize vitamins. If its quantity is reduced, it will cause the lack of vitamin K and vitamin B groups in the body.
Drug-induced malnutrition is mainly manifested as vitamin or mineral deficiency, some of which can also lead to digestion and absorption disorders of fat, protein and sugar, which can lead to nutritional deficiency in various applications over time. The key to prevent drug-induced malnutrition is to avoid drug abuse. If it must be used, especially for a long time, the diet should be adjusted according to the nutrients that may be lacking, and the corresponding vitamins and minerals should be taken when necessary.
Some patients with mild cold, fatigue and fatigue often seek infusion treatment from doctors on the grounds that the symptoms can disappear earlier, but in fact, this is due to insufficient understanding of static pulse infusion. Indeed, for clinicians, infusion is a common and very important treatment for some serious diseases. There are two main purposes: one is to supplement the substances that the human body has lost or lacked, such as water, electrolytes, vitamins and minerals; Second, drug treatment (such as antibiotics, etc. ) it is through intravenous administration to achieve better results. However, intravenous infusion also has adverse reactions, and common infusion reactions are caused by drug particles. Not long ago, more in-depth research found that the reaction of intravenous infusion was much more serious than we thought, which attracted widespread attention. Therefore, I would like to remind everyone here: if the drug can be used orally or intramuscularly to achieve the therapeutic purpose, do not use intravenous infusion.
5. Toxins from food (be careful, this is too important for everyone)
1) vegetable pollution poisoning
Vegetables are a huge flora. At present, there are more than 200 species cultivated in China. Among them, 70~80 kinds of production and consumption are more common. Some vegetables are more or less infested with pests, and the amount of pesticides used and the degree of pollution that follows are different. In recent years, chickpea is famous for its serious pesticide pollution. Because of biochemical reasons, pests like to eat this vegetable, and they often have to spray pesticides many times during their growth. Pesticide pollution is quite serious, while carrots, celery, parsley, lettuce, lettuce, chrysanthemum brain and so on. Because there are few insects, pesticides are rarely sprayed, so pesticide pollution is naturally much lighter. Vegetable pollution is also closely related to seasons. The vegetables planted in May ~ 10 during the peak period of insect pests are seriously polluted by pesticides. In the low temperature season, there are fewer pests, so the pesticide pollution is also light.
The pollution caused by pathogens such as bacteria, viruses and parasite eggs is called biological pollution, which is mainly caused by dumping harmless human and animal feces and urine on vegetables in production. The severity of biological pollution is closely related to the height of plants. Vegetables growing on the ground, such as chicken feathers, lettuce, mustard, spinach, coriander, etc. They are all eaten directly after being poured on the leaves, and the biological pollution is of course serious; Vine vegetables should be cultivated with columns or scaffolding, and edible fruits should be kept away from the ground. When pouring human and animal manure, vegetables and fruits, such as cucumber, loofah, cowpea, tomato, etc. And those who don't topdress after flowering, such as edamame, are rarely involved, and the biological pollution is naturally much lighter.
Excessive use of chemical fertilizers (such as urea and ammonium sulfate). ) it is also easy to cause pollution, which is manifested by excessive accumulation of nitrate in vegetables. Nitrate vegetables are not toxic, but they will be converted into nitrosamines in human digestive tract. Nitrosamine is a carcinogen, and frequent consumption of vegetables rich in nitrate will pose a potential threat to human health. According to the relevant research results, the average nitrate content of various vegetables shows the following laws from high to low: root vegetables >; Green leafy vegetables > cabbage > onion and garlic > beans >; Pumpkin > boxed fruit > edible fungi. In short, vegetables with vegetative parts (roots, stems and leaves) are more polluted, while vegetables with reproductive parts (flowers, fruits and seeds) are less polluted. Tomatoes, peppers, wax gourd, cucumbers and mushrooms all have the ability to eliminate the adverse effects of nitrate. Nitrate-rich vegetables include spinach and mustard.
Therefore, vegetable pollution is mainly biological pollution and chemical pollution according to its nature; According to the way of pollution, it is mainly manifested as body surface adhesion pollution and body enrichment pollution. When the human and animal manure mentioned above is poured in, bacteria, viruses, parasite eggs and pesticides will attach to the leaves and stems of vegetables. This kind of pollution attached to the body surface can remove some or most of the pollutants after soaking in clean water, while the concentrated pollution in the body, such as nitrate accumulation in vegetables and systemic pesticides absorbed by vegetables, exists in vegetables, and cleaning and cooking are of no help. In order to avoid suffering, choose to consume and arrange to eat insect-infested vegetables in winter. This can greatly reduce the harm of pesticide pollution to human body.
Here, I have to remind everyone that it is best to remove residual pesticides as much as possible by eating fruits and vegetables: First, repeatedly cleaning and soaking for a long time, preferably soaking in detergent for half an hour; The second is to peel as much as possible; Third, what can be heated must be eaten after heating; The fourth is to soak in ozone water.
2) Poisons from animal food pollution
Clenbuterol can increase protein synthesis and decrease fat synthesis. When it is added to veterinary drugs or livestock feed, it can obviously reduce the weight of pigs and increase the lean meat content. This invention also won the scientific and technological progress award. However, "Clenbuterol" is quite toxic. Excessive use or disease-free use will cause adverse reactions such as muscle tremor, palpitation, trembling, headache, nausea and vomiting. Especially those patients with hypertension, heart disease, hyperthyroidism and prostatic hypertrophy are at greater risk.
The natural life span of a chicken is usually seven years. However, the maturity cycle of a farmed edible chicken only takes 7 weeks. Their growth process is unimaginable: as soon as the chicks are born, they are stuffed into a chicken coop with poor sanitary conditions and fed with spoons. When they came out to see the sunshine again, it was also the time when they were slaughtered. Although those feed manufacturers never admit that growth hormone is added to the feed. But the fact that it became a broiler within 49 days is the strongest evidence of using growth hormone.
With the improvement of living standards, the types of animal foods in people's diet have also increased greatly, and whether animal foods are safe and pollution-free has become a topic of special concern. People and animals are creatures in the biological chain. Animals eat toxic and harmful substances, which will remain in meat, milk, eggs and internal organs. When people eat animal food, these harmful and toxic substances will be accepted by everyone, thus causing harm to human health.
Of course, it is impossible for people to live in a vacuum society, thus effectively avoiding the pollution of food by many substances. But is there any way to avoid or minimize these pollutions and give yourself a healthy body? Generally speaking, it is safest to buy "organic food" and "green food", but it can provide us with quality food. However, at present, the output of this kind of food in China is low and the price is high, which can not meet the needs of consumers. Here, we need to remind you of some inedible meat products:
① The chicken's ass is pointed. Commonly known as "chicken ass", that is, the fat block above the anus of chicken. Because the tip of chicken buttock is the most concentrated place of lymph in chicken. Macrophages in lymph have a strong phagocytic effect on bacteria, viruses and carcinogens. And it can only swallow these poisons, but it can't destroy these harmful substances, so the tip of the chicken's ass has become a "warehouse" for storing bacteria and some carcinogens. Therefore, it should be removed during slaughter.
② Pork dates. The dark red and grayish yellow pimples in pork are pig lymph nodes. Because lymphocytes can filter and devour pathogenic bacteria and viruses, jujube gathers a lot of toxic substances, which is harmful to human health after eating.
③ The smelly glands of rabbits. Rabbits have three pairs of glands. One pair is the mouse glands under the skin of the stem back of male rabbits or the clitoris back of female rabbits. The second pair is the brown mouse gland next to the mouse gland; The third pair is the chain-shaped rectal glands located on the medial wall of the rectal terminal. Its taste is extremely smelly, harmful to health, and it is not suitable for eating with rabbit meat.
④ Black membrane of fish abdomen. There is a black film on the abdomen of fish, which is tightly attached to the inner wall of abdominal cavity. This membrane can protect the abdominal cavity of fish from internal organs, and at the same time it is a barrier for various harmful substances in internal organs to penetrate into muscles through the abdominal wall. The black film on the belly of fish contains a lot of bacteria, stolen goods, pesticides and so on. After eating, there will be symptoms such as nausea, vomiting and diarrhea.
⑤ Kidney is small. That is, the animal adrenal gland is located at the front end of the kidney (kidney) and is brown. Because the kidney contains hormones, it is not easy to be destroyed when cooking. If you eat it regularly, there will be an excess of gland hormones in the kidney, which will disturb the normal victory rhythm of the human body.
⑥ Thyroid gland of livestock. The thyroid gland of domestic animals is located at the back of the throat, near the trachea, and is generally divided into two lateral lobes. After eating thyroid by mistake, the concentration of thyroid hormone in the body will increase sharply, and there will be poisoning symptoms similar to hyperthyroidism.
6. Toxins in human body
We talked a lot about toxins in vitro, so how do toxins in the human body come into being?
1), nervous.
Due to the accelerated pace of modern life, increased pressure and nervous spirit, people have been in a busy working and living state for a long time. Once it exceeds the physiological adjustment range of human body, it will cause dysfunction of qi and blood of viscera, have adverse effects on the body, produce toxins, affect the distribution and quantity of neurotransmitters such as serotonin and dopamine in the brain, and may lead to symptoms such as irritability, insomnia, depression, anorexia, dull complexion, and black eyes.
2) Bad diet
Normal diet is the most basic condition for human body to absorb nutrition and maintain life activities. However, proper diet often turns into poison, which has adverse effects on the body. Such as unreasonable food structure: too much intake of high fat, high sugar, high salt, high calorie and high cholesterol, too little intake of plant food and fresh and active food; Violation of the principle of civilized diet, such as gorging, overeating, eating under emotional and emotional pressure, drinking water or drinks at the same time, eating overheated and supercooled food, eating fruits immediately after meals, eating irregularly, etc.; Eat too much, too full; "Junk food" and "dead food" play leading roles at the dinner table. The so-called "junk food" refers to the food in which the active substances and energy such as enzymes in natural instruments are eliminated after the above two processes. Diet exceeds the digestion and absorption function of human spleen and stomach, which can lead to food retention, spleen and stomach damage, abdominal distension, fever, acid reflux, anorexia, diarrhea, dull complexion and acne. For example, eating too much meat, drinking and eating seafood for a long time leads to overnutrition and fat accumulation in the body, followed by arteriosclerosis, fatty liver and hyperlipidemia.
3) Smoking addiction
Smoking addicts have dark skin, purple lips and premature facial wrinkles. This is the influence of nicotine and other harmful substances in cigarettes on human body. Nicotine has a great destructive effect on skin capillaries, which affects the blood circulation of the skin and leads to nutrient absorption disorder. In addition, carbon monoxide in cigarettes combines with hemoglobin, which reduces the oxygen carrying capacity of hemoglobin and leads to hypoxia.
4) Staying up late for a long time
Adequate sleep is the guarantee of human health. Long-term staying up late or lack of sleep can cause dysfunction of endocrine system and immune system of central nervous system, imbalance of hormone secretion, disorder of organism metabolism, production of various toxins, and premature aging symptoms such as fatigue, shortness of breath, dull complexion, loss of appetite, bad breath, abdominal pain, abdominal distension, constipation, skin pigmentation, dry skin and alopecia.
5) Physical factors
People with poor physique are prone to metabolic disorders, which make normal physiological substances become unfavorable factors and toxic. For example, glucose is one of the main sources of human thermal energy. Once the fat metabolism is disordered and the blood lipid is too high, it will be harmful to health. In addition, metabolic waste can not be excreted in time, and it will also produce toxicity, and constipation is the most common one. Toxins produced by metabolism can not be excreted in time, and are absorbed excessively by the body to form new toxins, which can cause many diseases.
All the above are the sources of human toxins, some of which we can avoid and some of which we can't avoid. We can only use detoxification to clean up toxins to keep healthy.
