摘要

Biogenic secondary organic aerosols (BSOAs) are a significant component of atmospheric particulate matter, affecting both climate and air quality. This review explores BSOA formation from biogenic volatile organic compounds (BVOCs), particularly sesquiterpenes like β-caryophyllene, through oxidation by atmospheric oxidants. These processes lead to aerosol formation via gas-particle partitioning, condensation, nucleation, and heterogeneous reactions. The review simplifies complex reaction pathways to improve accessibility. Advanced analytical techniques such as high-resolution mass spectrometry and aerosol mass spectrometers are discussed, highlighting their role in BSOA detection and characterization. Laboratory chamber studies and field observations provide insights into BSOA dynamics under controlled and real-world conditions. Furthermore, atmospheric models are evaluated, with a focus on challenges in accurately representing BSOA formation and evolution due to their chemical complexity and variability. The impact of BSOAs on radiative forcing and cloud condensation nuclei (CCN) activity is examined, emphasizing their role in influencing Earth’s energy balance. Understanding BSOA properties, such as molecular weight, volatility, and functional groups, is crucial for predicting their behavior and atmospheric effects. The review calls for improved integration of scientific research and policy actions to address the environmental and public health concerns associated with BSOAs.
