- Abstract
- Volatile Organic Compounds (VOCs) emitted from vegetation (particularly isoprenoids) represent an important source of atmospheric hydrocarbons almost double the anthropogenic source. When biogenic VOC mix with NOx in the presence of UV radiation, ozone (O3) is formed. In Italy, optimal conditions for
O3 formation in terms of VOC/NOx ratios and abundance of UV radiation occur for long periods of the year. Moreover, Italian vegetation includes several species that are strong and evergreen isoprenoid emitters, and high temperatures for part of the year further stimulate these temperature-dependent
emissions. We review emission of isoprenoids from Italian vegetation, current knowledge on the impact of rising O3 levels on isoprenoid emission, and evidence showing that isoprenoids can increase both the O3 flux to the plant and protection against oxidative stress because of their antioxidant functions. This
trait not only influences plant tolerance to O3 but also may substantially alter the flux of O3 between atmosphere and biosphere. (literal)
