A PROMISING METHOD OF HYGIENIC EVALUATION OF AIR POLLUTION INSIDE THE MODULES OF THE INTERNATIONAL SPACE STATION BY HYDRAZINE DERIVATIVES
The increasing frequency of ISS egress operations resulted in ISS air pollution by an uncharacteristic group of toxic compounds, i.e. propellant residues and products of propellant incomplete burning. High reactivity and toxicity of these compounds necessitated the deveopment of a method of sanitary-chemical evaluation of ISS air safety given penetration of the new pollutants. The method is fulfilled in two stages. First is air sampling and then - sample analysis in ground laboratory by chromatography-mass spectrometry. Air sampling, as well as sample handling and analysis procedures were refined with the use of artificial gas mixtures. The proposed method shows promise as an instrument for the hygienic evaluation of ISS air pollution by hydrazine derivatives.
