Plants and trees naturally emit volatile organic compounds that can form aerosols.
Is it true that plants and trees naturally emit volatile organic compounds that can form aerosols?
Yes. Plants and trees naturally emit volatile organic compounds (such as terpenes and isoprenoids) that undergo atmospheric oxidation to form secondary organic aerosols.
Verdict: SUPPORTED · 7 sources for, 0 against · Last checked
The claim is specific, empirical, and directly tested in numerous atmospheric chemistry studies. Multiple provided papers confirm that biogenic volatile organic compounds (BVOCs) emitted by vegetation serve as major precursors for secondary organic aerosols (SOAs). Therefore, the balance verdict is SUPPORTED.
