Bottled Water (Plastic)
Moderate burden — Bottled Water (Plastic) adds a moderate, reducible exposure.
Single-use PET bottles.
The breakdown
Each driver rated 0 (none) to 10 (worst)
Evidence strength: strong · Detox Score = 100 − hazard×4.6 − exposure×3.4 − persistence×2.6, clamped 1–100.
What this means for you
A Detox Score of 42 places bottled water (plastic) in the Moderate band. The persistence rating is the standout concern here — these compounds linger in the body and environment for years. Studies find microplastic and nanoplastic particles in most bottled water, shed from the plastic itself and worsened by heat and storage time.
Frequently asked questions
Is bottled water (plastic) a toxic exposure?
Bottled Water (Plastic) has a Detox Score of 42 out of 100 (Moderate burden), which means it adds a moderate, reducible exposure. Studies find microplastic and nanoplastic particles in most bottled water, shed from the plastic itself and worsened by heat and storage time.
What is a safer alternative to bottled water (plastic)?
A lower-exposure swap for bottled water (plastic) is: Filtered tap water in a glass or steel bottle. Studies find microplastic and nanoplastic particles in most bottled water, shed from the plastic itself and worsened by heat and storage time.
