The cytotoxicity verification of the VOCs removal by means of photocatalysis

This paper constitutes the approach to correlate the results of gas purification properties performed with aid of photocatalysis with the cytotoxicity test results. The gas purification by means of photocatalysis is a subject well known a profusely described in literature. Easiness and continence of application causes the photocatalysis to be used in variety of industries, however this paper considers only automotive industry application. The effectiveness of photocatalysis have been proven experimentally by vast number of researchers. However, the literature contains only the information about the level of volatile organic compounds identification and reduction. The toxicity measure in terms of living cells was not yet fully tested and described in literature. Therefore, the standard chromatography test which enables quantitative identification of volatile organic compounds was confronted with a cytotoxicity tests revealing the virtual toxicity of gases before and after photocatalysis.
