本研究评估了当前美国环境保护署(EPA)监管模型AERMOD在模拟家禽蛋鸡设施中的颗粒物(PM10和PM2.5)扩散方面的性能。在污染源，PM10和PM2.5的日平均浓度估计分别为436.01+/-166.77微克米(-3)和291.09+/-105.81微克米(-3)。这相当于PM10和PM2.5的日平均排放速率分别为0.067-0.073克秒(-1)和0.044-0.047克秒(-1)。模拟的每小时PM浓度相对于污染源下风向测量的PM浓度显示出可接受的准确性。将平均周期从每小时增加到每天，可以改进预测。模拟结果显示，家禽养殖场及其周围的PM浓度均在国家环境空气质量标准之内。这项研究表明，AERMOD在家禽养殖场PM下风向影响的预测和评估中是有效的。
This study evaluates the performance of AERMOD, the current U.S. Environmental Protection Agency (EPA) regulatory model, in simulating particulate matter (PM10 and PM2.5) dispersion from a poultry pullet facility. At the source, the daily mean PM10 and PM2.5 concentrations with strong diurnal patterns were estimated to be 436.01 +/- 166.77 mu g m(-3) and 291.09 +/- 105.81 mu g m(-3),respectively. This corresponded to daily mean emission rates of PM10 and PM2.5 as 0.067-0.073 g sec(-1) and 0.044-0.047 g sec(-1), respectively. The modeled hourly PM concentration showed acceptable accuracy relative to the measured PM concentrations downwind of the source. Increasing the averaging period from hourly to daily resulted in improved prediction. The simulations revealed that PM concentrations at and beyond the property line of the poultry facility were within the National Ambient Air Quality Standards. This study suggested that AERMOD is effective in predicting and assessing the impacts of PM downwind of poultry facilities.
