	Term
	Biogenic Hydrocarbons	Definition: Biogenic hydrocarbons are naturally occurring compounds, including VOCs (volatile organic compounds) that are emitted from trees and vegetation. High VOC-emitting tree species such as eucalyptus can contribute to smog formation. Species-specific biogenic emission rates may be an important consideration in large-scale tree plantings, especially in areas with high ozone concentrations.
