Abstract: 
Emission and dispersal of microorganisms and odours from composting facilities were studied in a 3-year project at nine different composting facilities in Germany. Measurements were carried out under so-called 'normal-case', i.e. typical local climate conditions and working activities within the facilities, and 'real worst-case' conditions ('drainage flow' conditions) being characterized by the translocation of cold air mostly at night, and containing large amounts of bioaerosols. Highest concentrations of microorganisms were observed during turning of compost with a maximum of 2.4x10(6)cfu m(-3) for thermophilic actinomycetes. Other groups of microorganisms were detected in concentrations of about 10(5)cfu m(-3). During shredding of fresh organic material, the concentrations of all microorganisms reached 10(4)cfu m(-3). Here, odour concentrations turned out to be highest (up to 1,367 odour units (OU)m(-3)). At facilities equipped with a biofilter (odour reduction), a decrease in OU by a factor of 10 was observed. In the surrounding of the facilities, highest concentrations ranged between 10(1)-10(3)cfu m(-3) upwind and from 10(1)-10(4)cfu m(-3) downwind. The specific local meteorological situations must be considered carefully in advance and during sampling. Especially 'drainage flow' situations can lead to high microorganism concentrations (>10(4)-10(5)cfu m(-3) of thermophilic actinomycetes and thermophilic fungi) in the surroundings of composting facilities.
