There was made a hygienic assessment of the air environment of chemical production in Eastern Siberia for the production of commercial butyl alcohol of ISO - and normal structure and methyl-tret-butyl ether (MTBE). The company uses continuous processing cycles with a high degree of automation and mechanization of labor-intensive operations. A retrospective study of the air of the working area of these industries over the 13-year period found no exceedances in MAC of harmful substances (butyl alcohols, MTBE, and oil aldehyde, methanol, aliphatic hydrocarbons C1-C10, carbon monoxide, cobalt tetracarbonyl hydride), there was a noticeable downward trend over the observation period, which is associated with the introduction in the target industries of technical and sanitary-hygienic measures, optimization of working conditions. The studies carried out at the present time indicate a continuing effect on low-intensity chemical compounds operating in the said complex, which corresponds to the permissible level of the occupational risk.
