在环境空气中普遍存在的生物气溶胶，从具有露天处理区的堆肥设施中以高浓度释放出来。然而，生物气溶胶的空间和时间变异性，特别是与气象学的关系，还没有得到很好的理解。在这里，我们在2005年至2014年期间在英格兰的217个堆肥设施的4公里范围内的每个邮政编码加权质心处模拟烟曲霉的相对浓度。在卫星图像的帮助下对设施进行了地理编码。现有的生物气溶胶建模文献的数据被用来建立排放概况在ADMS。每个模拟设施之间的输入参数的变化被减少到最低限度。每个堆肥设施的气象数据来自最近的SCAIL-农业验证气象站。根据我们的研究结果，模拟的暴露风险主要由风速、风向和随时间变化的排放因素驱动，这些因素包括可堆肥废物的季节性波动。模拟的烟曲霉浓度从设施边界迅速下降，并在1.5-2.0 km以外达到稳定水平。当多个堆肥设施彼此相距4公里以内时，复杂的暴露风险模式显而易见。需要对设施附近的生物气溶胶进行更长期的监测，以帮助改进接触估计，从而评估对当地人口的任何健康风险。
Bioaerosols, ubiquitous in ambient air, are released in elevated concentrations from composting facilities with open-air processing areas. However, spatial and temporal variability of bioaerosols, particularly in relation to meteorology, is not well understood. Here we model relative concentrations ofAspergillus fumigatusat each postcode-weighted centroid within 4 km of 217 composting facilities in England between 2005 and 2014. Facilities were geocoded with the aid of satellite imagery. Data from existing bioaerosol modelling literature were used to build emission profiles in ADMS. Variation in input parameters between each modelled facility was reduced to a minimum. Meteorological data for each composting facility was derived from the nearest SCAIL-Agriculture validated meteorological station. According to our results, modelled exposure risk was driven primarily by wind speed, direction and time-varying emissions factors incorporating seasonal fluctuations in compostable waste. ModelledA.fumigatusconcentrations decreased rapidly from the facility boundary and plateaued beyond 1.5–2.0 km. Where multiple composting facilities were within 4 km of each other, complex exposure risk patterns were evident. More long-term bioaerosol monitoring near facilities is needed to help improve exposure estimation and therefore assessment of any health risks to local populations.
