在中试规模的污水污泥堆肥设施和其他两个选定的测试地点的机械搅拌堆肥堆的嗜热真菌机会主义烟曲霉的雾化进行了研究。气溶胶A.固定式堆肥堆下风处的烟曲霉浓度与搅拌式堆肥堆下风处的烟曲霉浓度相比不显著。这些气溶胶是由前端装载机移动和丢弃堆肥产生的。从排放点顺风处的真菌空气浓度被用来确定A.与移动操作相关的烟。最大发射率为4.6 � 106A。fumigatus particles per s，用于计算在距离排放源下风向1公里处具有限制性、中性和分散性大气混合条件的无障碍羽流中的预测浓度。
Aerosolization of the thermophilous fungal opportunist Aspergillus fumigatus from mechanically agitated compost piles was examined at a pilot-scale sewage sludge composting facility and two other selected test sites. Aerosols of A. fumigatus downwind from stationary compost piles were insignificant in comparison with those downwind from agitated piles. These aerosols were generated by a front-end loader moving and dropping compost. Aerial concentrations of the fungus at distances downwind from the point of emission were used to determine an emission rate for A. fumigatus associated with the moving operations. The maximum emission rate, 4.6 � 106A. fumigatus particles per s, was used to calculate predicted concentrations in an unobstructed plume with restrictive, neutral, and dispersive atmospheric mixing conditions up to 1 km downwind from the emission source.
