This energy-materials paper builds a bismuth molybdate and bismuth oxide composite with polypyrrole as a photocathode for hydrogen generation using sanitation water as electrolyte. It contains no exposure or toxicity information for bismuth and does not measure bismuth release into the water.
Key numbers
This paper reports no numerical findings relevant to bismuth exposure.
Methods (brief)
Two-step synthesis, X-ray diffraction and optical characterization, and photocurrent and hydrogen evolution measurements (abstract).
Evidence fitness
This is a materials or analytical chemistry paper in which bismuth is a component of an engineered material. It does not support dietary exposure or toxicity claims for bismuth, and no bismuth was measured in food, water, feed, soil or human or animal tissue.
Limitations
Not relevant to food or health.
