Everyday exposure	5/10	Frequency of reuse (up to 27 times) was the main factor that linearly increased antimony leaching from PET bottles at 13-47 °C; the leached antimony (about 360 ng/L) did not pose a serious health risk against current acceptable-intake estimates.

What this means for you

Single-use bottles aren't built for reuse — wear and heat increase leaching and bacterial growth. A proper reusable is cleaner and cheaper over time.

Evidence strength: moderate
