Workplace pollution in two viscose plants

The CS2 and H2S pollution was evaluated in two viscose plants: a sponge factory and a rayon spinning mill. Two kinds of sampling were used: background samples with the help of a laboratory van equipped with a Gas Phase Chromatograph and an Air Sampler allowing sequential workplace monitoring. personal samples. The results show the H2S pollution is not negligible and can even be equal to that with CS2 in some workshops (e.g. the spinning-room). The proposed methodology permits an accurate description of the pollution.
