Long "latent" in Taiwan, "plasticizer food" came to light, causing an uproar, Comment network had the circumstances surrounding the incident a detailed interpretation. So, plasticizing agent in the end? What harm? People how to stay away from it?
Plasticizer in the end?
Beijing Chaoyang Hospital, Capital Medical University, occupational diseases and poisoning Medicine,plastic film said Hao Fengtong chief physician, said plasticizing agent or plasticizer, the product range up to hundreds of species, but is most commonly used phthalate (DEHP) compounds . Plasticizers are not food additives added to food is strictly prohibited.
color film In a variety of plastic products, especially in the PVC products in order to increase the plastic strength of plasticity and increase the plastic, you need to add phthalates, its content and sometimes up to 50% of the product.pvc shower curtain Hao Fengtong said, over time, phthalates and other substances from the plastic gradually transferred to the external environment, the prevalence of airborne dust in the atmosphere, rivers and soil. Phthalates through the respiratory tract, gastrointestinal tract and skin absorption into the body, the earth has become the most widespread environmental pollutants, many of the atmosphere, lakes, rivers and soil have been detected in different concentrations of phthalic ester. From this perspective, China issued the plastic limit is very wise, should insist on implementation.
So,pvc plastic film exactly what plasticizer risks?
Hao Fengtong that phthalates on the toxicity of experimental research, modern medicine gives a positive answer. However, acute toxicity of phthalates is very low. China scholars to mice through drinking water intake channel concentrations were 250 mg / l, 500 mg / l, 1000 mg / l, 2000 mg / l of DEHP lasted 60 days, male and female mouse liver, kidney, heart, lungs The organ coefficient appeared in varying degrees, exceptions.
Hao Fengtong said that so far, people due to a variety of phthalate toxicity mechanism of a lack of thorough understanding. There is no dispute that the biological toxicity of phthalates exist "dose - effect" relationship. Although phthalates are widely distributed in the environment, but it is far below the actual exposure to the exposure dose in experimental animals. In this regard, the toxicity of phthalates is to prevent exposure dose control.
Department of Endocrinology, Beijing Union Medical College Hospital, Professor Yan Wu University, said: "We all know that arsenic to poison people, but small doses of arsenic to treat leukemia, but. DEHP is the same, whether it will harm the human body, depending on the 'amount' of how much. And animals metabolic tests also proved that, DEHP itself within two days can be excreted. "
How to avoid the dangers of plasticizers?
Whether from food containing plasticizers, plasticizers can be away from it? Experts said plasticizer widely found in every corner of life. So far, domestic and foreign media have been exposed in the following items may contain plasticizers: food packaging bags, plastic wrap; hair gel, lipstick, nail polish, lotion and other cosmetics; disposable plastic cups, plastic gloves, raincoats, shoes , imitation leather, shower curtains and other daily necessities; instant noodles, powder cleaning products, medical devices (syringes, blood bags and medical plastic hose, etc.), children's toys.
Wu Yan said the study, according to our modern way of life has become completely escape the plasticizer is almost impossible, but it did not need to stress, because the normal life and exposure to the plasticizer will not harm the human body. However, it is usually exposed as little as possible should contain plasticizers, plastic products.
Secretary-General of the International Association for Food Packaging Dong Lion said plasticizer everywhere, wear, use items, many will use DEHP. Most easily in daily life that is in contact with food wrap, plastic wrap into polyethylene (PE) plastic wrap and polyvinylchloride (PVC) plastic wrap. If plastic products are marked with PVC, which contains a plasticizer on the description, purchase and use requires special attention. Particular attention is the food with plastic wrap must not be placed in the microwave, especially meat, because the plasticizer Once exposed to oil, will release toxic substances. In addition, when the selected children's products, too soft, too small plastic products to buy as little as possible.
Experts suggest that to reduce plasticizer absorption, in daily life to change some habits. First, in the selection of food containers, plastic material should be avoided in favor of high-quality stainless steel, glass and ceramic containers. Second, the preservation of food with plastic wrap should choose not to add plasticizer PE material, and preferably less plastic wrap, plastic bags and oil paper food packaging and in full bloom. Third, try to avoid using plastic containers to put hot water, hot soup, tea and coffee, try to use less plastic bags or plastic containers in full bloom foods, especially hot and oil foods. Fourth, minimize the use of plastic containers to put food in the microwave heating.
