Locating industrial VOC sources with aircraft observations.

Area of Science:

• Environmental Science
• Analytical Chemistry
• Atmospheric Chemistry

Background:

• Industrial areas pose risks due to Volatile Organic Compounds (VOCs).
• Monitoring VOCs is crucial for setting exposure limits and informing policy.
• Identifying emission sources aids in targeted environmental management.

Purpose of the Study:

• To measure and locate VOC emission sources in the Marghera industrial area.
• To utilize Solid Phase Micro Extraction (SPME) for VOC analysis.
• To integrate aerial atmospheric measurements with ground-based emission modeling.

Main Methods:

• Solid Phase Micro Extraction (SPME) for sample collection.
• Gas chromatography-mass spectrometry (GC-MS) for VOC identification.
• Aerial platform for atmospheric data acquisition.
• Gaussian Plume modeling for source localization.

Main Results:

• Detection of a wide range of VOCs in the industrial area.
• Successful identification of specific VOC emission sources.
• Spatial mapping of VOC concentrations and their origins.
• Validation of the Gaussian Plume model for source estimation.

Conclusions:

• The SPME method coupled with aerial monitoring is effective for VOC source identification.
• The study provides data to inform environmental safety policies for industrial zones.
• Understanding VOC distribution is key to mitigating pollution risks.
