Common NameCr(6+)
DescriptionHexavalent chromium , also known as chromium hexavalent ion or chromium ion (6+), belongs to the class of inorganic compounds known as homogeneous transition metal compounds. These are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Hexavalent chromium is possibly neutral. Hexavalent chromium is formally rated as a carcinogen (by IARC 1) and is also a potentially toxic compound. Hexavalent chromium is a known carcinogen. It can also cause transcriptional repression by cross-linking histone deacetylase 1-DNA methyltransferase 1 complexes to CYP1A1 promoter chromatin, inhibiting histone modification. Skin contact can cause skin ulcers. Trivalent chromium may also form complexes with peptides, proteins, and DNA, resulting in DNA-protein crosslinks, DNA strand breaks, DNA-DNA interstrand crosslinks, chromium-DNA adducts, chromosomal aberrations and alterations in cellular signaling pathways. Hexavalent chromium's similarity to sulfate and chromate allow it to be transported into cells via sulfate transport mechanisms. Chronic inhalation especially has been linked to lung cancer.
