During September 18–19, several members of the Air-Omics group carried out a field sampling campaign at two industrial emission sites, focusing mainly on electronic circuit source (珠海紫翔&安捷利). The team systematically collected a wide range of environmental samples, including emission air, wastewater, soil, and tree bark, in order to investigate the release pathways and environmental impacts of industrial pollutants. This campaign also represents a key research task under their CAS pilot project, aiming to provide essential data support for understanding industrial sources of emerging contaminants and their environmental behaviors.
