A specific sea vegetable used in Japanese cooking.
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.
A Detox Score of 51 places hijiki seaweed in the Moderate band. The chemical-hazard rating is what drives the score down. Food-safety agencies in several countries advise against eating hijiki specifically, after testing found inorganic arsenic at levels far above other edible seaweeds. This is unusual among sea vegetables — the common alternatives are not implicated.
