Comparative Study[Monitoring the quality of drinking water and air in the industrial center].
The quality of potable water at the exit point for distribution networks and a network for three zones (central, east and northern) where the Orenburg population lived compactly were studied which showed its difference. The complex anthropogenic and total oxidative loads created by aqueous and air environments were calculated; the maximum values for inhabitants of the east part of the city were established, which correspond to the higher levels of nitrates, chlorides, and sulfates in the water and its general mineralization and general rigidity.

[Occupational risk for development of respiratory diseases in foundry shop workers at machinery industries].
The paper provides the results of assessment of prior and posterior occupational risks and those of questionnaire analysis in foundry shop workers from machinery enterprises. According to the data of attestation of job places, the working conditions of major foundry occupations were ascertained to correspond to class 3, grades 1 to 3. ⋯ According to the results of a questionnaire survey, more than half of the workers sought medical advice for bronchopulmonary pathology. Determination of whether there is, in terms of the etiological share, a cause-and-effect relationship between RDs and working conditions has shown that the occupation was highly responsible, which suggests that harmful industrial factors make a considerable contribution to the development of RDs in the workers of the enterprises under study.

There are various harmful physical factors in the passenger and work premises of the Moscow underground. Noise is the most common harmful factor. The normative documents regulating noise in the underground were found to have discrepancies, which in practice makes it difficult to define whether the level of the sound is in compliance with the existing specifications and hence to determine effective actions made to mitigate its negative impact on the underground passengers and personnel.
