Abstract. Hexavalent chromium (Cr(VI)) is a sort of common industrial poison and environmental pollutant posing great health threat to the population. Appropriate biomarkers are indispensable indicative tools in the biological monitoring and health risk assessment of Cr(VI).
10 Νοε 2016 · The results showed that blood chromium level, superoxide dismutase (SOD) and malondialdehyde (MDA) levels were significantly higher (p < 0.001) while the level of glutathione (GSH) was ...
1 Μαΐ 2021 · Particles smaller than 5 μm are absorbed by the blood or mucociliary clearance in the pharynx; the rest remain in the lung. The maximum absorption peak of hexavalent chromium is observed at 6 h, with a decrease at 72 h.
What processes are covered by this guidance? All electrolytic chromium processes except trivalent chromium including: hard chrome plating; decorative chrome plating (bright and black chrome); anodising (though this is not a plating process); and. some passivation processes.
Analytical Methods: Hexavalent Chromium Plating Solutions. Mary C. Traficante, Atotech USA Inc., Rock Hill, SC. This is a brief review of accepted analytical methods for chromium plating solutions. The relative standard deviation (RSD) of certain methodologies is presented.
