생물기원 휘발성 유기화합물(BVOC)은 주로 식물을 비롯한 생명체가 생성하고 배출하는 휘발성 유기화합물입니다. 이소프렌(C₅H₈)과 테르펜이 가장 흔한 BVOC입니다. 자연적으로 발생하는 BVOC의 배출량은 전 세계적으로 인위적 VOC를 능가할 정도로 방대합니다. BVOC는 식물의 방어 및 신호 전달에 중요한 역할을 하며, 대기 오존과 2차 유기 에어로졸의 주요 전구물질로서 대기 질과 기후에 영향을 미칩니다.

Biogenic VOCs represent a massive flux of carbon from the biosphere to the atmosphere, estimated to be around 1 billion metric tons per year. Isoprene is the single most emitted non-methane organic compound, primarily from deciduous trees. Monoterpenes ([latex]C_{10}H_{16}[/latex]), such as alpha-pinene and limonene, are characteristic emissions from coniferous trees. Plants produce these compounds for various ecological reasons, including deterring herbivores, attracting pollinators, protecting against thermal stress, and communicating with other plants.
Once in the atmosphere, BVOCs are highly reactive. Their oxidation, primarily by the hydroxyl radical ([latex]bullet OH[/latex]), ozone ([latex]O_3[/latex]), and the nitrate radical ([latex]NO_3bullet[/latex]), is a central process in atmospheric chemistry. This oxidation contributes significantly to the formation of secondary pollutants. In polluted, high-NOx environments, BVOC oxidation can exacerbate ozone smog formation. In cleaner environments, it leads to the formation of secondary organic aerosols (SOAs), which are tiny airborne particles that can affect cloud formation, the Earth’s radiation balance, and human health. The interplay between natural BVOC emissions and anthropogenic pollutants is a key area of research in understanding regional air quality and global climate.
