The adverse effects of atmospheric particulate matter (PM) on health and ecosystems, as
well as on meteorology and climate change, are well known to the scientific community. It is …

Occurrences and exposure to high levels of microbial bioaerosols such as pathogenic
bacteria, fungi, fungal spores, and viruses can be linked to the deterioration of the …

To better understand the effects of wildfires on air quality and climate, it is important to
assess the occurrence of chromophoric compounds in smoke and characterize their optical …

Abstract Particulate matter 2.5 (PM2. 5) filter samples were collected in July and October
2014 and January and April 2015 in urban Shanghai and analyzed using ultrahigh …

Levoglucosan has been widely used to quantitatively assess biomass burning's contribution
to ambient aerosols, but previous such assessments have not accounted for levoglucosan's …

Brown carbon (BrC) contributes significantly to aerosol light absorption and thus can affect
the Earth's radiation balance and atmospheric photochemical processes. In this study, we …

Nitrites (NO2–/HONO), as the primary source of hydroxyl radicals (• OH) in the atmosphere,
play a key role in atmospheric chemistry. However, the current understanding of the source …

Filter samples of fine particulate matters were collected at four sites in northern China
(urban, rural, and mountain) in summer and winter, and the contents of nine nitrated phenols …

Abstract Nitro-monoaromatic hydrocarbons (NMAHs), such as nitrocatechols, nitrophenols
and nitrosalicylic acids, are important constituents of atmospheric particulate matter (PM) …

Nitrous acid (HONO) significantly contributes to OH radicals in the atmosphere, whereas the
HONO sources need to be urgently further explored. The photolysis of solid nitroaromatic …
