Observation and characterization of environmental pollution, focussing on Volatile Organic Compounds (VOCs), in a high-risk industrial area, are particularly important in order to provide indications on a safe level of exposure, indicate eventual priorities and advise on policy interventions. The aim of this study is to use the Solid Phase Micro Extraction (SPME) method to measure VOCs, directly coupled with atmospheric measurements taken on a small aircraft environmental platform, to evaluate and locate the presence of VOC emission sources in the Marghera industrial area. Lab analysis of collected SPME fibres and subsequent analysis of mass spectrum and chromatograms in Scan Mode allowed the detection of a wide range of VOCs. The combination of this information during the monitoring campaign allowed a model (Gaussian Plume) to be implemented that estimates the localization of emission sources on the ground.
观察和描述环境污染，特别是聚焦于挥发性有机化合物（VOCs），在高风险工业区域非常重要，这有助于提供安全暴露水平的指示，确定潜在的优先事项，并为政策干预提供建议。本研究旨在使用固相微萃取（SPME）方法测量 VOCs，直接与小型飞机环境平台上的大气测量相结合，评估和定位马尔盖拉工业区 VOC 排放源的存在。对收集的 SPME 纤维进行实验室分析，随后在扫描模式下对质谱和色谱图进行分析，可检测到广泛的 VOCs。在监测活动期间结合这些信息，可实施一个模型（高斯烟羽模型）来估计地面上排放源的位置。
