An Estimate of the Possible Contribution of Biogenic Sources to Airborne Hydrocarbon Concentrations

摘要

The importance of plants as sources of photoreactive hydrocarbons, oxidant precursors, is widely discussed. The two main questions appear to be: (1) are natural hydrocarbons emissions large enough to result in significant atmospheric concentrations (2) do naturally emitted hydrocarbons contribute significantly to ozone formation. This note addresses the first question.
