When it comes to plastic products , I believe everyone is familiar, because plastic products are everywhere in our lives. Generally, plastic containers such as beverage bottles used at home often like to collect them, and then sell them after a certain amount has been accumulated. Some people are used to reusing plastic containers, such as vinegar and oil. This seemingly environmentally friendly or economical practice has already laid a health hazard for the family.
It is understood that each plastic vessel has a number at the bottom (it is a triangle with an arrow and a number inside the triangle). According to experts, plastic containers with numbers "3" and "7" usually contain the toxic substance bisphenol A (BPA). As the plastic ages, is heated in a microwave oven or exposed to the sun, bisphenol A is easily released. Contaminated food and the environment, endangering human health.
Plastic products with a number of "3" are prone to harmful substances at high temperatures, and even release harmful substances during the manufacturing process. When harmful substances enter the human body with food, they may cause diseases such as breast cancer and birth defects. Currently, containers of this material have been used less for packaging foods. If you are still using it, don't let it get hot.
The plastic product with the number "7" is a material that is widely used, especially in bottles, kettles, cups, etc., because it contains bisphenol A and is controversial. Some experts have said that in theory, as long as the bisphenol A is converted into a plastic structure during the process of making PC, it means that the product is completely free of bisphenol A, let alone release. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into food or drink. Therefore, everyone should be careful, pay special attention when using this plastic container. Therefore, if you have a plastic container at home, you can dispose of the "3" and "7" at the bottom in time, or put it in a cool, ventilated place. Do not reuse disposable plastic containers to avoid harm to your health.
