But as you write in your original posting, people should be aware of the health risks of Potassium dichromate which according to Wikipedia is "one of the most common causes of chromium dermatitis<http://en.wikipedia.org/wiki/Dermatitis>; [...] especially of the hand and fore-arms, which is chronic and difficult to treat. Toxicological studies have further illustrated its highly toxic nature. With rabbits and rodents, concentrations as low as 14 mg/kg have shown a 50% fatality rate amongst test groups. [...] As with other CrVI compounds, potassium dichromate is carcinogenic<http://en.wikipedia.org/wiki/Carcinogen> and should be handled with gloves and appropriate health and safety protection. The compound is also corrosive<http://en.wikipedia.org/wiki/Corrosive> and exposure may produce severe eye damage or blindness.[9]<http://en.wikipedia.org/wiki/Potassium_dichromate#cite_note-MSDS-9> Human exposure further encompasses impaired fertility, heritable genetic damage and harm to unborn children."
