Biogenic volatile organic compounds BVOCs

Biogenic volatile organic compounds (BVOCs) can provide important information about diverse processes taking place in plants such as the response to stress and signaling to its environment, and about the biological pathways of formation of different compounds. BVOCs are also of interest to atmospheric scientist, due to the fact that they can be involved in mechanisms of ozone, aerosol, and particulate formation, affecting the local chemistry of the atmosphere. 

As for the primary trace chemical species in the remote natural atmosphere where there is no influence of anthropogenic activities, methane (CH4) emitted from lakes and marshes, biogenic volatile organic compounds (BVOCs), nitric oxide (NO) from natural soils and lightning, dimethyl sulfide (DMS) from marine organisms, O3 descended from the stratosphere can be conceived. Among them, the most important chemical species that is subjected to photolysis by the actinic flux (see Sect. 3.5) in the troposphere is O3 and NO2 (see Sects. 4.2.1 and 4.2.2).
