Hexavalent chromium wastes need to be chemically reduced to trivalent chrome in the shop’s treatment plant. This necessitates the use of expensive chemicals such as sulfur dioxide, sodium metabisulfite or sodium borohydride. Also considerable hazardous sludge is generated during the neutralization step of the treatment process due to the high chromium concentration of the plating solutions. Haz...

background: biomonitoring provides a useful tool to estimate the genetic risk from exposure to genotoxic agents. the aim of this study was to assess the potential cytogenetic damage associated with occupational exposure to hexavalent chromium by using micronuclei (mn) as a biomarker. methods: this was a cross-sectional study and all participants were males. both the exposed and control individu...

Abstract Since the 2017 REACH restrictions on hexavalent chromium, aeronautics industries have been seeking substitute processes for chromium plating. So far, use of trivalent chromium-based precursors seems to be best solution in terms process adaptation. The development such requires a better understanding plating bath chemistry. More specifically, there is need characterize complexation mech...
