Discover the hidden dangers behind the ordinary appearance of BPA plastics and the scientific measures to protect our health from the risks of this type of plastic.
BPA Plastic: What You Need to Know
BPA, or Bisphenol A, is a chemical that has been used in the industry since the 1950s. Discovered by a Russian scientist in 1891, BPA has become a key component in the production of hard plastics, especially polycarbonate (PC) and epoxy plastics. Everyday products such as water bottles, children’s toys, CD and DVD discs, as well as sports equipment, often contain BPA.
Among the 7 common types of plastics, BPA is especially prevalent in 3 types of plastics:
- Plastic #3 (PVC): This type of plastic is often used to produce transparent food packaging, cooking oil bottles, toys, and other products. The toxins in this plastic can be released at high temperatures, and the recommended usage temperature is below 81 degrees Celsius.
- Plastic #6 (PS or polystyrene): Plastic #6 is often used to produce disposable food containers. It can release toxins at high temperatures and in acidic or strong alkaline environments. Therefore, this type of plastic is not recommended for long-term storage of food and beverages.
- Plastic #7 (PC and other types): This is commonly used to produce large water jugs and some food containers. It is considered the most dangerous type of plastic. It is prone to leaching BPA into food, which can negatively affect health.
When purchasing plastic products, it is important to check the plastic identification symbol and avoid using the above 3 types, which are usually marked with a triangle with 3 arrows at the bottom of the product. It is best to choose products labeled “BPA-Free” to ensure safety for use.
