Use plastic beverage bottles to hold hot water? Beware of poison

Recently, a post titled "There is a secret under the drink bottle and not to be used repeatedly" has been widely circulated on the Internet. This has also caused many people to pay attention to the issue of repeated use of beverage bottles. The reporter looked at a variety of beverage bottles and found that there were numbers on the bottom of each bottle. Relevant experts said that plastic bottles of different materials differ greatly in terms of reuse. Recycling of plastic bottles is safe when used at low temperatures. However, long-term and repeated use of plastic bottles is certainly harmful to the human body.

Some citizens love to drink in plastic bottles

On June 21, the reporter found a Weibo on the microblogging microblogging, saying that a 12-year-old girl from the United Arab Emirates had cancer because she used the same water bottle for 16 consecutive months. The content of the post mentioned that plastic bottles contain a plastic material called PET (polyethylene terephthalate) that is safe to use once. If you reuse it for frugality or convenience, there is a risk of cancer. .

Is repeated use of plastic beverage bottles harmful to the human body? Reporter conducted an interview. The public, Ms. Sun, said that she often used plastic drink bottles to hold water. “It's a pity to lose things. It's very convenient to store things. It is both economical and environmentally friendly.” Ms. Wang said that she went to the hospital a few days ago and bought mineral water. After drinking a half bottle of hot water on the water dispenser, the bottle became hot and deformed and became a “burning neck”. After opening the lid, it smelled burnt. In plastic, she felt dizzy, nauseous, and tired after drinking a little water.

The owner of the private car Mr. Li told reporters that in order to facilitate and save money, he often uses mineral water bottles as drinking cups. Since the weather is relatively hot recently, when he drinks water, he will feel plastic smell, but he does not think there is anything wrong.

The bottom number represents different from "material"

According to the content mentioned by Weibo, the reporter examined the various beverage bottles and found that there are numbers on the bottom of each bottle. According to Zhang Lin, an industrial expert from a plastics product company in Qingdao, the triangle at the bottom of the plastic bottle is made up of three arrows, meaning "recyclable and recyclable". It is not a mark that can be reused. Numbers 1 to 7 inside the triangle, different numbers represent different plastic materials.

It is understood that the state stipulates that PET plastic bottles must be used once. Enterprises cannot recycle and repeat filling. Plastic bottles are supplemented with additives such as plasticizers, gloss enhancers, and colorants during the production process. These chemical components, if dissolved, are toxic to the human body.

Repeated use of health risks

According to the reporter, the recycled plastic bottles are safe to use at low temperatures. Even if there are poisonous and harmful substances inside, it is safer to use them at low temperatures. However, repeated use and prolonged use certainly have potential health problems. If it is poured into boiling water, the additives added in plastic processing will be dissolved in high temperatures, which is harmful to the human body, and some are even carcinogenic.

Zhang Lin reminded the public that PET itself is relatively stable, but it cannot be used repeatedly and for a long period of time. Repeated use certainly has potential health risks for the human body.

Inside the triangle of the bottom of the plastic beverage bottle, there are numbers 1 to 7, and each number represents a plastic container.

"1" PET (polyethylene terephthalate): mineral water bottles, carbonated beverage bottles. Use: heat-resistant to 70 °C, only suitable for warm drinks or frozen drinks, high temperature liquid or heating is easy to deform, there are substances that are harmful to the human body.

"2" HDPE (high-density polyethylene): cleaning products, bath products. Use: Can be reused after careful cleaning, but these containers are usually not well cleaned and become a hotbed of bacteria.

"3" PVC (polyvinyl chloride): It is rarely used for food packaging. Use: This material is susceptible to harmful substances at high temperatures. If used, do not let it heat.

"4" LDPE (low density polyethylene): cling film, plastic film and so on. Use: The heat-resistance is not strong, usually the qualified PE wrap film will be hot melt when the temperature exceeds 110°C. Therefore, when the food is in the microwave, it is necessary to remove the plastic wrap.

"5" PP (Polypropylene): microwave oven lunch box. Use: The only plastic box that can be placed in the microwave oven. However, some microwave lunch boxes are manufactured with No. 5 PP and the lid is made of No. 1 PET. Therefore, it is better to remove the lid before placing the container in the microwave oven.

"6" PS (polystyrene): bowl of instant noodle boxes, snack boxes. Use: Heat and cold, but not in the microwave. And can not be used to install strong acids, strong alkaline substances, so try to avoid using fast food boxes packed hot food.

"7" PC (other types): kettle, cup, bottle. Use: A material that is used in large quantities, especially for baby bottles, because it contains bisphenol A and is controversial. Do not heat during use. Do not shine in direct sunlight. Before use for the first time, wash with baking soda powder and warm water. Allow to air dry naturally at room temperature because bisphenol A releases more when used for the first time and after long-term use.
