According to the sanitary-hygienic legislation of Russia in the atmospheric air the following maximum permissible concentrations of sulfur dioxide should be met:

  • maximum one-time concentration (for sampling time of 20 min - 0,5 mg/m3);
  • daily average concentration is 0,05 mg/m3. In the air of working spaces the concentration of sulfur dioxides shouldn’t exceed 10 mg/m3.
