From the side of the evidence: if harmful, the state will not allow the tap water with chlorine disinfection. What's more, the residual chlorine in boiled tap water is basically non-existent, and most of it has evaporated. Theoretically speaking, chlorine can react with organic matter in water to produce carcinogens, but in the tap water treatment process, most of the organic matter has been disposed of, and the amount of organic matter in tap water is already very small, so the carcinogens produced by the reaction will be even less. On the other hand, the so-called carcinogenic substances in a certain concentration has a certain chance to cause cancer, this chance is one of millions, tens of millions, in the case of carcinogenic substances concentration of trace amounts, can not be said to have harm. The following content can refer to see:
Chlorine in tap water on the human body harm. Chlorine to water: adding chlorine, as an effective means of sterilization and disinfection, is still used by more than 80% of the world's waterworks. Therefore, a certain amount of residual chlorine must be maintained in municipal tap water to ensure that the microbiological indicators of drinking water are safe. However, when chlorine reacts with organic acids, many carcinogenic by-products are produced, such as trichloromethane. More than a certain amount of chlorine, itself, will also produce many hazards to the human body, and with an unpleasant odor, commonly known as "bleach smell". Now, most experts have reached a **** knowledge, the use of chlorinated water and drinking water chloride does have a certain relationship with the chance of cancer.
The United States Wisconsin hospital researchers found: free residual chlorine in tap water and derivatives of "trichloromethane, carbon tetrachloride and other carcinogens, mutagens", in addition to drinking from the mouth into the human body, there is also a large part of the people in the face, hand washing, gargling, from the skin, pores, hair into the human body. It is reported that the residual chlorine in water and its toxic and harmful substances, more than 80% from the skin into the human body. Therefore, the residual chlorine in water, impurities and pipelines, water tanks and other water pollution has a serious impact on human health.
In 1974, Rook of the Netherlands and Belier of the United States for the first time found that pre-chlorination and chlorine disinfection of water there trichloromethane (THMS), chloroform and other disinfection by-products (DBPS), but also has a carcinogenic, mutagenic effect. 80's, people have found that another type of chloroacetic acid (HAAS), cancer risk is greater, such as chloroform, dichloroacetic acid (DCH) and The carcinogenic risk of chloroform, dichloroacetic acid (DCH) and trichloroacetic acid (TCA) is 50 and 100 times higher than that of trichloromethane respectively. So far, with the advancement of science and technology, 2221 organic pollutants have been detected in water sources, while 65 have been found in tap water, of which 20 are carcinogens and 56 are mutagens.
Dr. Martin, an expert in health and nutrition in the United States, said: If humans can be free from chlorinated water, their life expectancy can be extended by 20-30 years, every family should be practicing the same standard of drinking water, water, drinking water is important, water is equally important, and the conditions of the family should have a set of centralized family water purifier (system).
Chlorine disinfectant disinfection of tap water, inexpensive, effective, easy to operate, popular, universal. However, chlorine is effective in killing bacterial cells, and likewise has a serious effect on other organisms' cells and human cells.
Boiling tap water, a carcinogen trichloromethane will be 3-4 times more than cold water, so we drink coffee, tea or soup every day, after heating and boiling drink; our body has increased 3-4 times the carcinogens. The tap water we drink in our daily life must be completely cleared of any residual toxins (residual chlorine in the tap water).
Chlorine is an inorganic volatile chemical that was used as a poisonous gas in World War I. It directly binds to skin and hair proteins, destroying their natural electrolyte reactions; adding chlorine to tap water is good for washing clothes, but definitely not for drinking or bathing. Chlorine added to water can cause your hair to dry out and break, and your skin to bleach and shed layers of skin and produce itchy, itchy dermatophyte allergies. Studies have shown that, for health reasons, for children and the elderly or allergic to chlorine will have a direct negative impact, even if the use of more hair care skin care products or medication to wipe the allergic skin, the effect is not directly remove the root cause of the water ""chlorine"", to the direct and effective.
Tap water is supposed to be a convenient and safe drinking water, in order to inhibit the bacteria in the water, adding chlorine in the process of water treatment. However, scientists have recently found that chlorine in the water, chlorine and organic compounds in the water to produce chloroform carcinogens. The dirtier the water, the more chlorine is added, the more trichloromethane is produced, and this compound cannot be removed by boiling.
We drink tap water every day, that is, it may contain harmful substances into the body, and the recent intestinal viruses are rampant, cancer every 10 minutes there is a cancer, more than 50,000 cancer infections per year in Taiwan, these are not only drinking water with tap water problems. Chlorine in external tap water has more direct harm to any oxidized surface with pores such as skin, nostrils, mouth, lungs, hair, eyes, meat, vegetables and fruits; because chlorine is easily and quickly absorbed by the above objects. Children's tender skin and hair are the most sensitive to this, scientific research has proved that: chlorine can not only be ingested through food, but also absorbed through the skin and have an impact on the human body, including bladder cancer, liver cancer, rectal cancer, heart disease, atherosclerosis, anemia, high blood pressure and allergies and other symptoms, which are all related to chlorine. Since chlorine is commonly used to disinfect public **** water, and its best solution is: choose a special water purifier for bathing that removes chlorine and impurities to protect your health.
Chlorine damage to the body: chronic poisoning is mainly manifested as neurasthenia syndrome, liver damage, digestive disorders, limb osteolysis, skin damage. This product is carcinogenic and can cause hepatic hemangiosarcoma.
Digestive system: loss of appetite, nausea, eructation, bloating, constipation and so on. Hepatomegaly, abnormal liver function.
Skin changes: there are dry, cracked skin, pimples, acne, or changes such as keratinization of palms and thinning of nails.
Carcinogenic: vinyl chloride to liver hemangiosarcoma has been listed as a national statutory list of occupational diseases
Chlorine is a strong *** yellow-green gas, 2.43 times heavier than the air, soluble in water (water-chlorine volume ratio of 1:2.5), easy to be absorbed for the activated carbon. Room temperature and six atmospheric liquefaction of liquid chlorine, specific gravity of water 1.56 times. Chlorine is widely used, mostly used for water disinfection, pulp bleaching, bromine, bleaching powder (calcium hypochlorite), hexachloride, rubber, ink and pigment, oil and grease, polyvinyl chloride and hydrochloric acid, pesticides, and so on. Chlorination of the metallurgical industry, chlor-alkali industry, there are also a large number of chlorine gas emissions. Such as every ton of liquid chlorine production, diaphragm electrolysis will have 9.45 kg, mercury electrolysis method has 18-72.5 kg of chlorine discharged.
People's stomach contains five thousandths of hydrochloric acid to help digestion, kill germs. Chlorine is a very active element, almost all common metals and carbon, nitrogen, oxygen, all non-metals other than direct compounds (in the absence of water does not work with iron, so the use of steel bottles of liquid chlorine). Low concentrations of chlorine (hydrogen chloride) in the atmosphere can *** eyes, nose, throat; air containing one ten thousandth of chlorine will seriously affect human health. Inhalation of chlorine in the human body can poison the respiratory tract and mucous membranes of the skin. Mild poisoning with burning, pressure, laryngitis, itching, breathing difficulties, eye stinging and tearing. High concentrations of chlorine gas (hydrogen chloride) will cause chronic poisoning, rhinitis, bronchitis, emphysema, etc., and some will be allergic, dermatitis, eczema, etc.. Chlorine volatility is very strong, water vapor in the air can react with it to generate hydrochloric acid mist and hypochlorous acid, and wherever they are corroded items, endangering human beings, animals and plants. Therefore, the production and use of chlorine should be strictly managed to improve the process equipment, to prevent leakage and the comprehensive utilization of chlorine. For chlorine-containing waste gas, in the concentration of more than 1%, carbon tetrachloride or sulfur monochloride can be absorbed as an absorbent concentrated desorption to be recovered; dilute concentration of chlorine can be absorbed with water, lye and ferrous compounds, but pay attention to the secondary pollution problem
Why does chlorine lead to cancer? According to the United States of America, Anaheim, Southern California, held in September 1986, the American Chemical Society meeting pointed out that: a long time to rinse the hot bath is a kind of harm to health. The body is directly exposed to toxic chemicals (chlorine) that evaporate from the water and are absorbed directly into the skin. However, up to 6 to 100 times more chlorine is inhaled during bathing than is drunk into the body. When the residual chlorine in tap water combines with organic matter in the water, carbon tetrachloride, dichloroethanol, and trichloromethane are produced, and trichlorine (chlorine, bromine, chlorine, and bromine) can be used as an antimicrobial agent. Bromine, iodine), plus methane (hydrogen). Three chlorine (chlorine, bromine, iodine), plus methane (hydrogen), so called trichloromethane, its main products include CHCl3 (chloroform), CHBrCl2 (a bromine dichloromethane), CHBr2Cl (dibromo chloromethane), CHBr3 (bromoform), etc., the four are collectively referred to as the total trihalomethanes (TTHM). Trihalomethanes in water: Trihalomethanes are immediately absorbed into the human body, producing carbon dioxide, chloride ions, carbamide chloride (toxic gas) and other harm to the central functions, liver, kidney, teratogenic and carcinogenic.
If the tap water is boiled, and then open the lid for 15 minutes of continuous boiling can reduce THMs, but the boiling point of 100 degrees, the other carcinogens are completely ineffective, and even increase the concentration of other carcinogens in more than 60 kinds of other carcinogens, so no matter 『drinking』or 『use』; you must first remove the residual chlorine in the tap water in order to maintain your health. You may ask, even if chlorine is absorbed by the skin into the body, but the human liver itself has a detoxification function, inhalation and how? Of course, there is nothing wrong with this statement, just ask, water accounts for 70% of the body's weight ratio, when will our liver have a chance to breathe? In fact, chlorine in water is equivalent to candy wrapped in candy paper, we all know that when we eat candy, we must tear off the candy paper, so of course, when you use water to remove chlorine. In fact, scientific research has also proved that chlorine can not only be ingested through food but also absorbed through the skin and have an impact on the human body, including bladder cancer, liver cancer, rectal cancer, heart disease, atherosclerosis, anemia, hypertension and allergies and other symptoms are also related to chlorine. Since chlorine is commonly used to disinfect public **** water, and its best solution is to protect your health by choosing a special water purifier that removes chlorine and impurities.
Chemical fiber is harmful to the human bodyHello, if you are wearing underwear, then it is best to use cotton, because chemical fiber underwear is a number of chemical substances, which will *** skin, and this material is not very comfortable
Therefore, it is recommended that is said to be the main chemical fiber clothing is uncomfortable, other than the human body will not be too harmful, but if there are conditions, or cotton clothing is better, but if there is a good chance that you will be able to use it.
So the suggestion is that chemical fiber clothes are uncomfortable to wear, and the others are not harmful to the human body, but if there are conditions, cotton clothes are better
Is vinegar harmful to the body?
No! But don't overdo it!
chemical products do bed head will be harmfulhome textile products chemical content exceeds the standard
pH finger failed: textiles in the production process, to add some dyes, auxiliaries and finishing agents, these substances are more or less harmful to the human body. According to the National Textile Product Quality Supervision and Inspection Center, Mr. Ma, the pH value of the surface of the human skin is weakly acidic, if the pH value of the textile is unqualified, it will affect the acid-base environment of the human skin, causing skin allergies and other diseases.
Formaldehyde exceeds the standard: In addition to pH value, home textile products in the decomposable aromatic amines, formaldehyde and other substances more terrible. According to Mr. Ma, formaldehyde exists in the finishing agent of textile fabrics, is a toxic substance, absorbed by the human body, the skin, the respiratory tract has a strong *** effect, can lead to dermatitis, respiratory mucosal inflammation.
The use of decomposable aromatic amine dyes: the toxicity and carcinogenicity of decomposable aromatic amines is much stronger than formaldehyde, because formaldehyde has a *** sexual odor, easy to distinguish, easily soluble in water, consumers buy back the textiles, generally wash with water to remove most of the formaldehyde. However, decomposable aromatic amines are insoluble in water, colorless and tasteless, and are simply indistinguishable from their appearance, and can only be found through technical tests, and cannot be eliminated. Supplies containing this dye in contact with human skin, can cause a variety of malignant diseases, and may cause cancer.
Is polishing bad for you?Overall, polishing is harmful to the body. The dust and particles produced by polishing, if inhaled, can cause short-term or long-term harm to the human body. Especially in the radioactive substances, such as marble, lead-containing substances such as polishing, the harm is not to be underestimated. Therefore, in the polishing, to do a good job of labor protection measures, such as wearing protective clothing, wear protective masks, glasses, masks, gloves, etc., after the work is completed, be sure to take a bath in time, wash your hands and face.

The benzene-containing chemicals on the person have those injuries?Acute benzene poisoning clinical manifestations
1. Mild poisoning can have headache, dizziness, tears, dry throat, cough, nausea and vomiting, abdominal pain, diarrhea, unsteady gait; skin, nails and mucous membranes purple group, acute conjunctivitis, tinnitus, photophobia, palpitations, and pallor and other symptoms.
2. Moderate and severe poisoning, in addition to the above symptoms of aggravation, drowsiness, unresponsiveness, trance, etc., but also may be rapid coma, rapid pulse, blood pressure drop, the whole body of the skin, mucous membrane cyanosis, respiratory acceleration, convulsions, muscle tremor, and some patients may appear agitation, euphoria, delirium, and peripheral nerve damage, and even respiratory distress, shock.
Long-term inhalation will violate the human nervous system, acute poisoning will produce neurological spasm or even coma, death.
A large proportion of leukemia patients have a history of exposure to benzene and its organic products.
Metabolism Benzene enters the body mainly by respiratory inhalation (47-80%), gastrointestinal and skin absorption. A portion of benzene can be excreted through the urine, and the benzene that is not excreted is first oxidized by oxygen molecules under the action of cytochrome P450 monooxygenase in the liver to benzene epoxide (7-oxabicyclo[4.1.0]hept-2,4-diene). Epoxybenzene exists in equilibrium with its rearrangement product, oxabicycloheptatriene, a toxic intermediate produced during benzene metabolism. Three metabolic pathways follow: combination with glutathione to produce phenylmercapturic acid; continued metabolism to phenol, catechol, hydroquinone, meta-benzenetriol, o-benzoquinone, p-benzoquinone, etc., which are excreted as glucosinolates or sulphate-conjugated compounds; and oxidization to hasadienedioic acid. Ethanol and toluene reduce the toxicity of benzene.
Benzene metabolites into the cell, and the cell nucleus of the deoxyribonucleic acid (DNA) binding, will make the chromosomes change, such as some broken, some combined, which is cancerous (the image of mutation, because the chromosome is the genetic material, which controls the structure of the cell and the activities of life, etc.), and in the long term, it will lead to cancer.
Poisoning symptoms Short-term exposure
Benzene has a paralyzing effect on the central nervous system, causing acute poisoning. In severe cases, headache, nausea, vomiting, confusion, loss of consciousness, coma, convulsions, etc., and in severe cases, death will occur due to paralysis of the central system. Small amounts of benzene can also cause drowsiness, dizziness, rapid heart rate, headache, tremors, confusion and delirium. Ingestion of food containing too much benzene can cause vomiting, stomach pain, dizziness, insomnia, convulsions, rapid heart rate, and even death. Inhalation of 20,000 ppm benzene vapor for 5-10 minutes can be fatal.
Long-term exposure
Long-term exposure to benzene can cause great damage to the blood, causing chronic poisoning. It causes neurasthenia syndrome. Benzene can damage bone marrow, reduce the number of red blood cells, white blood cells, platelets, and make chromosomal aberrations, which can lead to leukemia and even aplastic anemia. Benzene can cause massive bleeding, thus suppressing the function of the immune system and allowing diseases to take advantage of it. Some studies have reported that the incubation period of benzene in the body can be as long as 12-15 years.
Women who inhale excessive amounts of benzene can suffer from irregular menstruation for months, and their ovaries can shrink. Effects on fetal development and on male fertility are not known. Inhalation of benzene in pregnant animals resulted in underweight larvae, delayed bone development, and bone marrow damage.
It has *** effects on skin and mucous membranes. It has been recognized as a carcinogen by the International Agency for Research on Cancer (IARC).
Benzene is a colorless, aromatic hydrocarbon, transparent, volatile, flammable and explosive. The principle of benzene poisoning is invasion of the human body by the respiratory tract. Inhalation of high concentrations of benzene vapor and a large number of benzene liquid contamination of the skin or accidental ingestion can cause acute poisoning. The oral lethal dose is about 10 ml. Its toxic effect is to inhibit the central nervous system, in addition to hematopoietic, respiratory system also has damage.
Is the battery production process harmful to the personYes. The pole plate contains antimony and cadmium. It is highly toxic.
Is bird feather dust harmful to peopleFeather dust is normal, but also a sign of bird health
If you think the bird's feather dust is too much, in addition to keeping the environment as ventilated as possible (so as not to accumulate too much feather dust and poor air), more to help the bird bathing can be moderately reduce the feather dust around the situation
What is a chemical productChemicals are a variety of elements (also known as chemical elements), Compounds and mixtures of elements, whether natural or man-made, are chemicals. According to the American Chemical Abstracts, there are now as many as 7 million chemicals in the world, of which more than 100,000 have been marketed as commodities, more than 70,000 are in regular use, and more than 1,000 new chemicals appear every year around the world.
