Drinking bottled beverages after exposure may cause precocious puberty. Do not drink bottled beverages that have been exposed to the sun or have been deformed by the bottle. The weather is so hot, is this plastic bottled beverage in the open air, will it be easy to deteriorate? At the gas station on the 11th Street, a box of mineral water is piled up next to the tanker, and the small sales department is full of various kinds. Plastic bottled beverages. Many car owners add oil, they will buy one or two boxes of beverages and put them in the trunk. Ye Peng, an associate professor of polymer science at Zhejiang Sci-Tech University, told reporters: Don’t drink such a drink. Nowadays, the material of mineral water bottles and beverage bottles is PET, and the chemical name is polyethylene terephthalate. These food grade plastic bottles are not designed to withstand high temperatures and need to be used under normal temperature conditions. Generally, they are safest below 70 °C. However, the quality of plastic bottles produced by some manufacturers is not good. During the polymerization of plastic bottles, some small molecules are not completely polymerized onto macromolecules. With the increase of temperature or strong light, some plasticizers and dyes will be analyzed. There will be some harmful substances dissolved in the drink. “These precipitated substances are invisible to the naked eye, so don’t drink if you are exposed to the sun or the bottle is deformed.” Ye Peng said. In addition, Sun Wei, the attending physician of the Emergency Department of the Oriental Hospital, also advises not to drink bottled beverages after exposure to sunlight: “The plasticizers and stains that are decomposed are called environmental hormones, and the immunity and fertility of the human body are all Influential, it will lead to masculinization of women, feminization of males, precocious puberty in young children, and the chance of liver cancer will increase in animal experiments.” Sun Wei specially reminds readers that it is hot now, try not to put drinks In the car or in the trunk, you should avoid drinking plastic bottles that have been exposed to high temperatures in the open air. Especially for young people of childbearing age, do not use or heat the plastic products repeatedly. Do not use plastic bags to pack some high temperature and fry. Foods that reduce the pollution of environmental hormones on their own.
