Animal trials with respirable dust gave some indication of inhalational toxicity, the effects of which were reversible at low concentrations. To alleviate the asso­ciated risk, some manufactures supply bismuth vanadate pigments in a free-flow­ing, low-dusting form, making them inaccessible to the lungs. The safety of these pigments is reinforced by their high density, which causes any airborne dust gen­erated to settle very quickly. Even so, the usual precautions and industrial hygiene rules necessary for handling chemicals must be observed.
