As critical precursors of ozone (O 3) and secondary organic aerosols, volatile organic
compounds (VOCs) play a vital role in air quality, human health, and climate change. In this …

Abstract The Pearl River Delta (PRD) region in southern China has been subject to severe
ozone (O 3) pollution during daytime and anomalous nocturnal O 3 increase (NOI) during …

Chemical losses of ambient reactive volatile organic compounds (VOCs) is a long-term
issue yet to be resolved in VOC source apportionments. These losses substantially reduce …

Mountainous background areas are typically considered to have a clean atmosphere where
peroxyacetyl nitrate (PAN) can be decomposed. This study demonstrated that PAN was …

Oxygenated volatile organic compounds (OVOCs) are important precursors and
intermediate products of atmospheric photochemical reactions, which can promote the …

Biogenic secondary organic aerosols (BSOA) play a crucial role in atmospheric chemistry,
with significant implications for air quality and human health. However, the mechanisms by …

Formaldehyde (HCHO) is an important trace gas that affects the abundance of HO 2 radicals
and ozone, leads to complex photochemical processes, and yields a variety of secondary …

Formaldehyde (HCHO) is one of the key indicators of severe photochemical pollution and
strong atmospheric oxidation capacity in southern China. However, current information on …

Emission characteristics of biogenic volatile organic compounds (BVOCs) from dominant
tree species in the subtropical pristine forests of China are extremely limited. Here we …

China suffered from serious and elevated ozone (O 3) pollution during 2014–2020. O 3
exposure increased with W126, a biologically based cumulative exposure index, at a rate of …
