损害器官、提高患病风险……这种“厨房神器”，真的别再用了！

Core Viewpoint - The article emphasizes the health risks associated with the reuse of plastic bottles, particularly PET bottles, which are commonly used for beverages and water. While these bottles are designed for single use, their repeated use can lead to the migration of harmful substances into food and liquids stored within them [1][4][10]. Group 1: Risks of Reusing Plastic Bottles - Reusing beverage and water bottles is not recommended due to potential health hazards [2][4]. - PET bottles are primarily designed for specific liquids like water and carbonated drinks; using them for other substances can increase the risk of harmful substance migration [5][7]. - High temperatures can cause PET bottles to deform and release harmful substances, especially when used to store hot food or placed near heat sources [8][9]. Group 2: Harmful Substances and Their Effects - The harmful substances that may migrate from PET bottles include antimony, a metal catalyst used in production, which can cause damage to various organs if accumulated in the body over time [12][13]. - Other organic compounds, such as plasticizers added to enhance PET's properties, can disrupt endocrine systems and increase cancer risk [14]. Group 3: Proper Use of Plastic Products - The article categorizes different types of plastics and their appropriate uses, highlighting that not all plastics are suitable for food storage, especially under high temperatures [16][18][21]. - Specific recommendations are made for using PP (polypropylene) containers for hot food, while caution is advised for other types like HDPE, PVC, and PS [16][17][22].
