Abstract

Rapid industrialization and the influx of human resources have led to the establishment of industrial complexes near urban areas, exposing residents to various air pollutants. This has led to a decline in air quality, impacting neighboring residential areas adversely, which highlights the urgent need to monitor air pollution in these areas. Recent advancements in technology, such as Solar Occultation Flux (SOF) and Sky Differential Optical Absorption Spectroscopy (SkyDOAS) used as remote sensing techniques and mobile extraction Fourier Transform Infrared Spectrometry (MeFTIR) used as an in situ technique, now offer enhanced precision in estimating the pollutant emission flux and identifying primary sources. In a comprehensive study conducted in 2020 in the Sinpyeong Jangrim Industrial Complex in Busan City, South Korea, a mobile laboratory equipped with SOF, SkyDOAS, and MeFTIR technologies was employed to approximate the emission flux of total alkanes, sulfur dioxide (SO), nitrogen dioxide (NO), formaldehyde (HCHO), and methane (CH). Using the HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) diffusion model, pollutant dispersion to residential areas was simulated. The highest average daily emission flux was observed for total alkanes, with values of 69.9 ± 71.6 kg/h and 84.1 ± 85.8 kg/h in zones S and S of the Sinpyeong Jangrim Industrial Complex, respectively. This is primarily due to the prevalence of metal manufacturing and mechanical equipment industries in the area. The HYSPLIT diffusion model confirmed elevated pollution levels in residential areas located southeast of the industrial complex, underscoring the influence of the dominant northwesterly wind direction and wind speed on pollutant dispersion. This highlights the urgent need for targeted interventions to address and mitigate air pollution in downwind residential areas. The total annual emission fluxes were estimated at 399,984 kg/yr and 398,944 kg/yr for zones S and S, respectively. A comparison with the Pollutant Release and Transfer Registers (PRTRs) survey system revealed that the total annual emission fluxes in this study were approximately 24.3 and 4.9 times higher than those reported by PRTRs. This indicates a significant underestimation of the impact of small businesses on local air quality, which was not accounted for in the PRTR survey system.

摘要

快速工业化和人力资源的涌入导致城市周边地区建立了工业园区,使居民暴露于各种空气污染物中。这导致空气质量下降,对周边居民区产生了不利影响,凸显了监测这些地区空气污染的迫切需求。技术上的最新进展,如用作遥感技术的太阳掩星通量(SOF)和天空差分光学吸收光谱法(SkyDOAS)以及用作现场技术的移动萃取傅里叶变换红外光谱法(MeFTIR),现在在估计污染物排放通量和识别主要来源方面提供了更高的精度。在2020年于韩国釜山新平长林工业园区进行的一项综合研究中,一个配备了SOF、SkyDOAS和MeFTIR技术的移动实验室被用于估算总烷烃、二氧化硫(SO)、二氧化氮(NO)、甲醛(HCHO)和甲烷(CH)的排放通量。使用混合单粒子拉格朗日综合轨迹(HYSPLIT)扩散模型,模拟了污染物向居民区的扩散。新平长林工业园区S区和S区的总烷烃平均日排放通量最高,分别为69.9±71.6千克/小时和84.1±85.8千克/小时。这主要是由于该地区金属制造和机械设备行业的盛行。HYSPLIT扩散模型证实了工业园区东南部居民区的污染水平升高,突出了主导西北风风向和风速对污染物扩散的影响。这凸显了针对下风居民区空气污染问题进行有针对性干预以解决和减轻污染的迫切需求。S区和S区的年总排放通量估计分别为399,984千克/年和398,944千克/年。与污染物排放和转移登记册(PRTRs)调查系统的比较显示,本研究中的年总排放通量比PRTRs报告的通量分别高出约24.3倍和4.9倍。这表明小企业对当地空气质量的影响被严重低估,而PRTR调查系统未考虑到这一点。
