WebThe structure of a potassium dichromate molecule is illustrated below. It can be noted that in the potassium dichromate molecule, potassium exhibits an oxidation state of +1, oxygen exhibits an oxidation state of -2 and chromium exhibits an oxidation state of +6. It can be noted that crystals of potassium dichromate have a triclinic structure. WebMaterials and methods: We evaluated primary DNA damage and frequencies of micronuclei (MN) and morphological nuclear abnormalities (NA) in erythrocytes in peripheral blood of the fish Oreochromis niloticus exposed to potassium dichromate at 12 mg l(-1). The genotoxicity and cytotoxicity of Cr(VI) in the onion (Allium cepa) test were also assessed.
