The results of microbiological spatial monitoring in Orenburg were evaluated. A biological variety of Staphylococcus on the nasal mucosa of schoolchildren were detected. The highest proportion of carriage of the pathogen Staphylococcus was found in different districts of Orenburg, which had the highest air pollution.

The physiological and biochemical states of children and adults who resided in the vicinity of the sulphide-containing gas processing plant were studied. The chemical agents emitted by the plant were found to have adverse effects of the children's functional status, namely, decreased vital capacity of the lung, mental performance, retarded sensomotor responses, altered enzymatic system activity.

A single and chronic inhalation exposure to a complex of chemical substances being part of hydrogen sulphide-containing natural gas (hydrogen sulphide, hydrocarbon, mercaptan, sulphur dioxide) results in a decline in humoral indicators of non-specific body resistance. At the same time the level of inhibition of lysozyme and complement activity along with the bactericidal activity of blood serum have direct dependence on the duration of chemical exposure and can be used as additional tests for early detection of body changes.
