Increasing population and urbanization have direct consequences on the sewer functioning. In order to identify and quantify gases and VOCs likely to be present in the sewers, methodological studies of sampling in sewer using airbags, canisters and adsorbent tubes were assessed, and methods of analysis by GC-MS were developed. The results obtained lead to propose improvements to sampling protocols in the sewers. The gas quantification is complicated by low gas concentrations, environment heterogeneity and a high hygrometry.
