Tang Jiao’s new paper ‘Molecular signatures and formation mechanisms of water-soluble chromophores in particulate matter from Karachi in Pakistan‘ was recently published in STOTEN; and it was of Karachi, Pakistan! Congratulations!
- EEM-PARAFAC identified two humic-like and one phenolic-like component in Karachi.
- Humic-like components consist of molecules with higher aromatic and oxidative degrees.
- Humic-like component with a longer emission maximum largely contributes to WS-BrC.
- Oxidation processes are important pathways for the formation of humic-like components.
