[Evaluation of occupational exposure to biological agents, endotoxins and PNOC in a sewage treatment plant].
The aim of this work has been to determine the occupational exposure to the biological agents and airborne dust in a sewage treatment plant in south Italy. The air samplings were performed in a sewage treatment plant in Calabria, in two different seasons (spring and summer) at 5 sites associated with various phases of sewage treatment process. In addition we have estimated the concentration of airborne endotoxins and PNOC (Particles Not Otherwise Classified) by using personal samplers. The results showed a significant variation in exposure to bioaerosols, endotoxins and PNOC depending on the sampling season: the PNOC concentration increase as much as the endotoxins concentration in spring and decrease in summer
