Recently, a shampoo product endorsed by a celebrity was involved in a “carcinogenic” controversy. According to the media, the shampoo product contains dioxane, which is classified as a carcinogen by the United States. Once again, this is a wake-up call for us to be careful about the carcinogenic effects of our daily necessities. Cancer has become the first “killer” that endangers people’s life and health, and most people are afraid of talking about cancer. Therefore, people expect to grasp some knowledge of cancer prevention to eliminate various factors that cause cancer. Among the daily necessities, the following ones may cause cancer risk and need to be highly alert when purchasing them. Housewives, please note 1. Cling film: Cling film has been widely used in daily life, but recently medical experts pointed out that cling film contains a plasticizer called DEHA, which can increase the adhesion of cling film, but will penetrate into food, especially high-fat food. This plasticizer can disrupt the body’s hormone metabolism and induce fetal birth defects, sperm reduction, breast cancer, and even mental disorders. After testing 1 9 types of cling film products, the Consumer Federation of America found that nearly half of the cling films contained a significant amount of plasticizer (DEHA), which was on average 8.5 times over the limit, based on the permissible range set by the European Community countries. After testing, China’s cling film plasticizer (DEHA) content close to or even more than the EC countries allow the standard value, if often applied, it may be harmful to human health. 2, plastic bags: the market for plastic bags used in raw materials mainly for polyvinyl chloride, polyethylene and polypropylene 3. Polyvinyl chloride monomer is a toxic substance, the International Agency for Research on Cancer (IARC) will be classified as a “human carcinogenic agent. The market with the color of plastic bags should not be filled with food. Polyethylene monomer is non-toxic, the antioxidants and stabilizers added are non-toxic. Polyethylene plastic bags are safe to use, but should not be filled with alcohol. Not suitable for packaging overheated food, pastries, sugar, milk powder, and can not be used for oil and aromatic items. Polypropylene plastic bags whose raw materials are non-toxic, tasteless, chemical and thermal stability are good, so it is a better food packaging materials. To distinguish between these three types of plastic bags, please be sure to pay attention to the following two points: the former is colored and will sink to the bottom when exposed to water, the latter is white and floating on the surface of the water. In short, the plastic bags with color may cause cancer, do not use it for food. 3, paint chopsticks: Chinese people eat with chopsticks, there are many kinds of chopsticks, including a paint chopsticks used by many people. Paint chopsticks are very beautiful in appearance, but the paint contains a variety of harmful chemicals, the nitro component of which is absorbed and will be synthesized with substances containing chloroethylamine, a powerful carcinogenic nitrosamine. Therefore, we are careful not to use painted chopsticks when choosing chopsticks. 4, crystal wine glass: crystal wine glass appearance crystal clear, workmanship is also very fine, but the crystal products should be concerned about the content of lead oxide up to 20% ~ 30%. After using crystal wine cups to hold wine l hours, the lead content in wine is l times higher. Lead is a toxic substance that has recently been designated by the U.S. Department of Health as a “substance reasonably believed to cause cancer”. 5, camphor pills: south of China, in the yellow plum days because of the humid climate, clothing is easy to mold, people used to use camphor pills to prevent mold. The mothballs placed in the closet may become the “invisible killer” hidden in the home. At present, most of the mothballs sold in supermarkets are not real mothballs, and more than 99% of their active ingredients are p-dichlorobenzene. Dichlorobenzene is an animal carcinogen. l994, the U.S. National Institute of Environmental Health Sciences in the 7th annual report of carcinogenic substances that dichlorobenzene is a confirmed experimental animal carcinogen. At the same time, Europe, the United States and Japan and other countries in the known to dichlorobenzene as a positive animal carcinogen and human suspected carcinogen after some have stopped production of this product. 6, poor quality paper: toilet paper, napkins, paper handkerchiefs, boxes of facial tissue, hand towels …… almost every day, we need to be in close contact with these hygiene products. As the name implies, hygiene products natural hygiene first, poor quality hygiene products, can be hazardous to health. However, foreign scientists have found that the white paper people use everyday is also one of the carcinogens. In addition to the serious excess of microbial content, some manufacturers add fluorescent whitening agent, talc and other harmful substances in the raw materials of paper, long-term use of these poor quality paper will irritate the skin, leading to skin allergies, serious still may cause cancer. Second, beauty lovers please note 1, hair dyes: whether hair dyes are carcinogenic has been a matter of concern. For a long time, scholars at home and abroad have conducted a lot of research on this issue. Most believe that hair dyes are mainly made of p-phenylenediamine and its derivatives, which are allergenic, mutagenic and even potentially carcinogenic. Long-term use will produce chronic accumulation, which over time will cause harm to human health and may promote the occurrence of cancer. Therefore, experts recommend that: if you do not have to dye, try to dye your hair, to reduce the chemical corrosion and damage to the hair itself. 2, antiperspirant: antiperspirant deodorant is a summer necessity for women, it reduces a lot of embarrassment, avoiding the armpit clothes are soaked with sweat, but also to prevent the smell of sweat around. However, experts suggest that antiperspirants should not be commonly used, as they contain varying degrees of added chemicals such as ethanol, formaldehyde, tannic acid, artificial fragrances and preservatives, which can cause varying degrees of allergic diseases, liver damage and even cancer. Scientists have found that if a woman wears antiperspirant twice a week, she will develop cancer 15 years earlier than a woman who does not use it. Therefore, do not use antiperspirant for a long time, if you must use the liquid application type, do not use the spray antiperspirant. 3.Nail polish: Nowadays, many fashion loving women like nail art and nail polish has become a necessary cosmetic for almost every beauty loving woman. But when women are in pursuit of beauty, they may not have thought that this has put them in an increasingly serious health crisis, and even brings the risk of cancer. Because of the complex composition of nail polish, mainly composed of solid substances and liquid solvents, which contains several “big-name” carcinogens. For example, Sudan red is the element often used when blending nail polish pigment, long-term exposure to harm can be imagined; not to mention, some nail polish in order to color more eye-catching, but also added heavy metal elements, accumulated over the years, will certainly produce toxicity in the body, affecting health. People generally do not know that the solvent components of ordinary nail polish are also basically toxic or harmful substances. The most powerful of them should be phthalates, benzene, formaldehyde, followed by acetone, ethyl acetate, etc. Phthalates can hinder the normal hormone balance, leading to serious reproductive damage and other health problems, with increased risk of breast or cervical cancer in women; and benzene and formaldehyde are also carcinogenic substances, lung cancer, blood system tumors and these two are closely related. Third, students please note 1, correction fluid: many primary and secondary school students currently have a box of correction fluid placed in the stationery box, as a replacement for the eraser used for many years. Although the application of correction fluid is more convenient than the eraser, but experts pointed out that students use correction fluid is quite harmful. The main components of correction fluid are trichloroethane, methylene chloride and xylene, in addition to titanium dioxide and artificial flavors. Now medical science has also confirmed that long-term exposure to the above-mentioned chemicals, the light is prone to dizziness and sleepiness, mental fatigue, loss of appetite and slow action, etc., the heavy susceptible to blood system diseases (such as leukemia, etc.) and tumors, 2, scented stationery: nowadays, the scent of learning stationery has become almost stationery stores to attract primary and secondary school students “sought-after goods “. Scented erasers, scented books, ballpoint pens that can write with scented handwriting, etc.. More and more scented stationery into the learning life of primary and secondary school students. According to the relevant departments testing found that many of the stationery with scent contains formaldehyde, benzene and other toxic chemicals to varying degrees, long-term use not only makes people dizzy, nausea, but also can cause leukemia or cancer. 3, luminous watches: according to the British “Sunday Telegraph” reported that there is a fashionable plastic watches can glow at night, because this watch contains the radionuclide tritium. Tritium is a radioactive form of hydrogen, which can be used to make the watch glow. People who wear such watches absorb high doses of tritium into their bodies, thus risking cancer. Therefore, it is important to be fashionable but not to disregard your health and protect yourself from harmful substances.
