Spatial variation of sources and photochemistry of formaldehyde in Wuhan, Central China

Spatial variation of sources and photochemistry of formaldehyde in Wuhan, Central China

In August 2016, ambient formaldehyde (HCHO) and related parameters were measured simultaneously at a suburban site (Wujiashan, WJS), an urban site (Ziyang, ZY) and a roadside site (Hankou, HK) in Wuhan, Central China. The mixing ratios of HCHO at WJS (2.1 ± 0.2 ppbv) were comparable (p > 0.05) to...

Zusammenfassung:In August 2016, ambient formaldehyde (HCHO) and related parameters were measured simultaneously at a suburban site (Wujiashan, WJS), an urban site (Ziyang, ZY) and a roadside site (Hankou, HK) in Wuhan, Central China. The mixing ratios of HCHO at WJS (2.1 ± 0.2 ppbv) were comparable (p > 0.05) to those at ZY (2.2 ± 0.4 ppbv) and lower (p
