自然灾害和人为灾害与空气质量问题有关，因为污染物可能在环境中重新分布。我们的目标是进行空气中的苯，甲苯，乙苯，二甲苯（BTEX）和标准的空气污染物在北卡罗来纳州期间和之后的飓风佛罗伦萨的浓度时空分析。风暴过后（2018年9月）立即进行了三次采样活动，每隔四个月进行一次。沿沿着主要道路测量苯系物。通过模型预测了同期标准空气污染物浓度。空气污染物和可能的点源之间的相关性进行了空间回归。苯（在所有采样期间）和PM2.5（大部分是在佛罗伦萨之后立即观察到）超过环境空气标准。对两者来说，更高的浓度和加油站之间存在联系，特别是在佛罗伦萨之后。其他污染物的浓度一般低于监管关注的水平。通过表征灾害和“正常”条件下的空气质量，本研究展示了空气污染物的空间和时间变化。我们发现，只有苯和PM2.5处于潜在的关注水平，飓风过后立即出现局部增加。这些物质在未来的灾害响应研究（DR2）调查中值得特别关注。
Natural and anthropogenic disasters are associated with air quality concerns due to the potential redistribution of pollutants in the environment. Our objective was to conduct a spatiotemporal analysis of air concentrations of benzene, toluene, ethylbenzne, and xylene (BTEX) and criteria air pollutants in North Carolina during and after Hurricane Florence. Three sampling campaigns were carried out immediately after the storm (September 2018) and at four-month intervals. BTEX were measured along major roads. Concurrent criteria air pollutant concentrations were predicted from modeling. Correlation between air pollutants and possible point sources was conducted using spatial regression. Exceedances of ambient air criteria were observed for benzene (in all sampling periods) and PM2.5 (mostly immediately after Florence). For both, there was an association between higher concentrations and fueling stations, particularly immediately after Florence. For other pollutants, concentrations were generally below levels of regulatory concern. Through characterization of air quality under both disaster and “normal” conditions, this study demonstrates spatial and temporal variation in air pollutants. We found that only benzene and PM2.5 were present at levels of potential concern, and there were localized increases immediately after the hurricane. These substances warrant particular attention in future disaster response research (DR2) investigations.
