Moderate burden — Sea Salt (Microplastics) adds a moderate, reducible exposure.
Salt evaporated from seawater.
Each driver rated 0 (none) to 10 (worst)
Evidence strength: moderate · Detox Score = 100 − hazard×4.6 − exposure×3.4 − persistence×2.6, clamped 1–100.
A Detox Score of 59 places sea salt (microplastics) in the Moderate band. The persistence rating is the standout concern here — these compounds linger in the body and environment for years. Multiple international surveys have detected microplastic particles in the large majority of sea salt brands tested, tracking the plastic load of the source water. Rock salt comes from ancient deposits and consistently tests lower.
Sea Salt (Microplastics) has a Detox Score of 59 out of 100 (Moderate burden), which means it adds a moderate, reducible exposure. Multiple international surveys have detected microplastic particles in the large majority of sea salt brands tested, tracking the plastic load of the source water. Rock salt comes from ancient deposits and consistently tests lower.
A lower-exposure swap for sea salt (microplastics) is: Mined rock salt, which does not pass through seawater. Multiple international surveys have detected microplastic particles in the large majority of sea salt brands tested, tracking the plastic load of the source water. Rock salt comes from ancient deposits and consistently tests lower.
