<unk>  refers to any poisonous toxic effect in an organism or cell that results from exposure to specific forms of<unk> —especially hexavalent<unk> . Hexavalent<unk>  and its compounds are toxic when inhaled or ingested. Trivalent<unk>  is a trace mineral that is essential to human nutrition. There is a hypothetical risk of genotoxicity in humans if large amounts of trivalent<unk>  were somehow able to enter living cells, but normal metabolism and cell function prevent this.
