RESUMO
The paper describes the results of a study of ambient air microbiological pollution in the working premises and equipment surfaces in the main shops of the biological waste water purification station of a cardboard-polygraphic plant. The findings suggest that there is high microbial contamination of the working environment, which should be born in mind on developing measures to optimize working conditions and on studying morbidity rates among the workers.

Municipal waste, sand trap sediment, floatable substances, raw sedimentation sludge, biological solids, a mixture of compact and dehydrated sediments, ashes, combustion gases and waste by GOST 12.1.007-76 are shown to be classified as classes 3 and 4 hazard. The conditions contributing to the occurrence of acute and chronic intoxications, infectious diseases, and helminthic invasions in the personnel, to environmental pollution at the basic stages of municipal waste and combustion sediment utilization are considered.
