Core Viewpoint - The article highlights the health risks associated with the reuse of plastic bottles, particularly PET bottles, which are commonly used for beverages and food storage. Group 1: Health Risks of Reusing Plastic Bottles - Reusing beverage and mineral water bottles may seem environmentally friendly but poses significant health risks [2] - PET plastic, commonly used for beverage bottles, is safe under specific conditions but can become unsafe if reused or stored improperly [5][6] - Changing the contents of PET bottles can lead to the release of harmful substances, especially when storing acidic liquids like vinegar [7][8] Group 2: Temperature and Aging Effects - PET is not heat-resistant and should not be used for liquids above 70°C, as high temperatures can cause deformation and release harmful substances [8] - Prolonged use of PET bottles can lead to aging, increasing the migration of harmful substances into stored food [9][10] Group 3: Types of Harmful Substances - Harmful substances that may migrate from PET bottles include antimony, a toxic metal that can accumulate in the body and cause irreversible damage to organs [11] - Other organic compounds, such as phthalates, are often added to enhance the properties of PET but can disrupt endocrine systems and increase cancer risk [12][13] Group 4: Proper Use of Plastic Products - Different types of plastics have varying safety profiles and should be used according to their specifications to minimize health risks [14][15] - Specific guidelines for various plastics, such as HDPE, PVC, LDPE, PP, PS, and others, indicate their temperature tolerances and suitability for food storage [16][17][18][19][20][21][22]
