1 Μαΐ 2021 · Hexavalent chromium is more pernicious in comparison to trivalent form. Chromium negatively affects crop growth, total yield and grain quality. Exposure of chromium even at low concentration enhances its accretion in cells of human-beings and animals which may show detrimental health effects.
2 Σεπ 2023 · The immobilization of hexavalent chromium was caused by the induced reduction of ferrous ions to stable trivalent chromium, which also significantly reduced the amount of extractable hexavalent chromium from TCLP to below the standard limit by 94% .
8 A hexavalent chromium electroplating bath produces severe off gassing, resulting in the creation of a large amount of chromic acid mist at the surface of the plating tank. exposure include dermatitis, hypersensitivity reactions, eczema, and kidney or liver damage.
1 Ιουλ 2021 · Chromium ions, especially hexavalent ions (Cr (VI)) generated through the different industrial process such as tanneries, metallurgical, petroleum, refractory, oil well drilling, electroplating, mining, textile, pulp and paper industries, are among toxic heavy metal ions, which pose toxic effects to human, plants, microorganisms, and aquatic lives.
1 Αυγ 2022 · Indications of chromium toxicity in plants include reduction of seed germination, retardation of growth, reduction of yield, inhibition of enzymatic activities, weakening of photosynthesis, nutrient, oxidative disparities, and genetic mutation.
Soluble hexavalent chromium compounds, and in particular chromic acid (chromium trioxide), are commonly used as electrolytes in electroplating and anodising. In these processes the bursting of small gas bubbles generated by electrolysis causes the formation of mists (fine droplets of electrolyte).
