Abstract
Characteristics of biogenic VOC (Volatile Organic Compounds) as well as methodology of BVOC (Biogenic VOC)
emission estimation are presented in this article. It has been shown in previous studies (e.g. Simpson et al, 1995) that contribution of
volatile organic compounds (VOC) emitted from biogenic sources to total amount of VOC in the atmosphere can be significant.
Especially while modeling photochemical processes over forested areas biogenic sources should not be neglected. Emissions of
volatile organic compounds – isoprene and monoterpenes from forest ecosystems in the area of Czech Republic were estimated.
Results were compared with antropogenic emission data in different regions of the Czech Republic. It has been shown that the
amounts of biogenic VOC emissions are comparable with emissions from anthropogenic sources in most of the regions. Spatial and
temporal distributions of emissions are presented as well.
