[Air-borne microbes in the vicinity of sewage treatment plants].

Measurements of air-borne germs were conducted over one year at several sewage treatment plants with different loads and sewage treatment methods. The investigations were intended to show possible air-borne loads in the sewage treatment plants and their immediate vicinity, taking into account different climatic conditions. The results lead to the conclusion that neighboring residential areas or factories in the vicinity of sewage treatment plants are not exposed to air-borne hazards.
