The concept of working culture is intended in this context to mean a reflection of the essential value systems adopted by the undertaking concerned. Such a culture is reflected in practice in the managerial systems, personnel policy, principles for participation, training policies and quality management of the undertaking.

Toxicity[ edit ] Hexavalent chromium compounds are genotoxic carcinogens. Due to its structural similarity to sulfate, chromate a typical form of chromium VI at neutral pH is transported into cells via sulfate channels. California has finalized a Public Health Goal of 0.

Some removal technologies include transporting contaminated soil offsite to a landfill, using ion exchange resins to reduce chromium VI concentrations to less than detectable limit and granular activated carbon GAC filter.

Containment technologies can be employed with the use of physical barriers such as grouts, slurries or sheet piling. Attempts have been made to test the removal or reduction of hexavalent chromium from aqueous solutions and environment.

For example, a research study conducted by the School of Industrial Technology, University Sains Malaysia in found that chitosan coated with poly 3-methyl thiophene can be effectively employed for removal of hexavalent chromium ions from aqueous solutions.

Chitosan is a very cheap, economical, and environmentally friendly substrate for coating of this polymer. Adsorption of chromium VI is found to be effective in the lower pH range and at higher temperatures and subsequent desorption is readily achieved upon alkaline treatment of the adsorbent.

The subsequent amendments provided a basis for the federal government to begin regulating pollutants, implement wastewater standards, and increase funding for water treatment facilities among other things. Current policies in the United States[ edit ] The current EPA standard in measuring chromium, is in reference to total chromium, both trivalent and hexavalent.

However, preliminary findings from water tests conducted by the Environmental Working Group EWGsuggest that chromium is most often found in the hexavalent form; the more toxic of the two.

In the EPA released a toxicological review of hexavalent chromium. This study looks at chronic oral exposure of hexavalent chromium in rats, and its association with cancer.

The other study mentioned is a human health assessment of chromium, titled Toxicological Review of Hexavalent Chromium.

The final human health assessment is currently in the stage of draft development. The EPA gives no forecast to when the review will be finalized and if a decision will be made. Army relied on hexavalent chromium compounds, called Cr VIto protect its vehicles, equipment, aviation and missile systems from corrosion.
