[The microbiological analysis of the air in sewage treatment plant in the summer season].

The aim of this paper was the analysis of microbiological quality of air based on studies made in 2002-2004 in sewage treatment plant in Szczecin. The collection of samples was made with sampling by aspiration method with MAS-100, twice in 2002 and once time in 2003 and 2004. The studies were performed according to Polish Standards PN-89/Z-04111/01-02 and PN-81/C-04615/27 in one season (summer). The points of samples collection were established in individual way for the sewage treatment plant. They were at the ground--on the borders and in 50 and 150 m distance. The studied air was characterized with different level of microbiological pollution--from non-polluted to strongly polluted. The biggest amount of strongly polluted air was received in establishing the total amount of TVC 37 bacteria, Staphylococcus, Actinomycetes but in establishing Staphylococcus, Pseudomonas fluorescens, the air was not strongly contaminated. It was seen that little deterioration quality of air (year 2002) and in 3 years made the possibility of isolating the same bacteria.
