[Evaluation of atmospheric pollution in industrial environment using gas-chromatographic technics].

Several analytical techniques for the evaluation of different classes of air pollutants that can be found in working places are described. Particularly an automatic apparatus for monitoring total organic substances less methane, and one, employing specific detection and selective columns for the automatic and continuous determination of light sulfur compounds, are described. An analytical procedure for trapping and selective analysis of organic substances is presented. This includes the description of trapping and enriching devices and of a semi-automatic apparatus for the gaschromatographic analysis of the samples trapped. Some applications of these analytical techniques are described.
