Biogenic volatile organic compounds are emitted by plants and influence human and environmental health. They contribute to the formation of pollutants such as ozone and secondary organic aerosols, thereby influencing air quality and climate. Here we review biogenic volatile organic compounds with focus on biosynthesis, release to the atmosphere, distribution at various scales, tropospheric chemical processes, and secondary organic aerosols. Biogenic volatile organic compounds are emitted primarily through enzymatic pathways in response to environmental factors, varying across plant species and ecosystems. These emissions exhibit heterogeneity at multiple scales, influenced by meteorological conditions and plant structure.

植物排放的生物挥发性有机化合物会影响人类和环境健康。它们有助于臭氧和二次有机气溶胶等污染物的形成，从而影响空气质量和气候。在这里，我们回顾了生物成因挥发性有机化合物，重点关注生物合成、释放到大气中、各种尺度的分布、对流层化学过程和次生有机气溶胶。生物挥发性有机化合物主要通过响应环境因素的酶途径释放，因植物物种和生态系统而异。这些排放在多个尺度上表现出异质性，受气象条件和植物结构的影响。
