In this contribution, we report the study of nuclear resonance magnetic spectroscopy techniques (H-NMR, C-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 PM were found to be between 15.66 and 142.19 µg.m. As results, H-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.
在本研究中，我们报告了核共振磁共振波谱技术（H-NMR、C-NMR 和 2D-NMR）在大气气溶胶中水溶性有机化合物（WSOC）功能组成特征化方面的研究效率。选择的地点是我们位于阿尔及利亚布伊希迈勒市的科学技术研究中心（CRAPC），该地区的 PM 浓度在 15.66 和 142.19 µg·m-3 之间。结果表明，H-NMR 分析显示了生物材料和城市及生物质燃烧排放物的共存。通过对每个 1H NMR 光谱区域的定量积分，确定了主要来源。通过使用 HSQC 技术，在生物样品中揭示了许多峰，包括生物质燃烧。另一方面，通过特定的 NMR 光谱，可以识别各种有机化合物的来源及其功能组成，也可以用于调整周围的有机气溶胶源。
