Short summary
Here we reported the development of a PTR-ID-CIMS to investigate industry-related emissions of VOCs in the Yangtze River Delta (YRD) region, the largest economic zone in China. We observed strong primary HCHO emissions from the industrial zone that overwhelmed local HCHO secondary formation. These primary HCHO sources can potentially lead to severe local and regional air pollution formation. Therefore, primary industrial HCHO emissions should be strictly monitored and regulated in this region.
