Is It Safe to Drink Bottled Water Left in the Car Trunk During Summer?
1 Answers
Bottled water left in the car remains safe to drink even after being exposed to intense sunlight. Below are relevant details: 1. Material of water bottles: PET has a heat resistance of up to 70 degrees Celsius. Beyond this temperature, the material may soften, but this only causes physical changes (water temperature rise) and does not result in the dissolution of harmful chemicals. The leakage of toxic substances is almost negligible. PET is a stable material that only undergoes chemical changes above 100°C-120°C, a temperature unattainable inside a car. 2. Methods to reduce car temperature: Open all four doors for ventilation before entering; after entering, roll down all windows and turn the air conditioning to maximum.
