Abstract Background Carbonaceous aerosols emitted from indoor and outdoor biomass burning are major risk factors contributing to the global burden of disease. Wood tar aerosols, namely, tar ball particles, compose a substantial fraction of carbonaceo

Biomass burning (BB) is an important source of primary organic aerosols (POA). These POA contain a significant fraction of semivolatile organic compounds, and can release them into the gas phase during the dilution process in transport. Such evaporat

Secondary organic aerosol (SOA) from indole was produced in a smog chamber under different relative humidity (RH = 3, OH, OH + NOx, and NO3). The mass absorption coefficients were measured by extracting SOA in methanol and taking absorption spectra i
