title: [Demonstration of gram-negative bacteria and endotoxins in the air surrounding a sewage treatment plant: effect of contaminated aerosols on the health status of the staff].
abstract: Data on airborne gram-negative bacteria and endotoxin contamination in a sewage treatment plant are reported and compared with data from similar plants in Scandinavia. Respiratory, digestive, and cutaneous symptoms were investigated on the basis of medical files. The contamination levels which can be considered safe are discussed in the light of the actual exposure of workers.
