Water-soluble organic compounds (WSOC) from atmospheric aerosols in Bou-Ismail (Algeria)

In this contribution, we report the study of nuclear resonance magnetic spectroscopy techniques (¹H-NMR, ¹³C-NMR, and 2D-NMR) efficiency in the characterisation of the functional composition of water-soluble organic compounds (WSOC) from atmospheric aerosols. The chosen site was our scientific and technical center of research (CRAPC) situated in Algerian Bou-Ismail city. where the concentrations of PM₁₀ were found to be between 15.66 and 142.19 µg.m^-3. As results, ¹H-NMR analysis showed the coexistence of biological material and emissions from urban and biomass burning. The dominant source was identified by quantitative integration of each 1H NMR spectral region. By using the HSQC technique, many peaks are revealed in biogenic samples including biomass burning. On the other hand, the identification of the source of various organic compounds and their functional composition is possible through specific NMR spectra, which can also be used to adjust the surrounding organic aerosol sources.
