利用流通式气室封闭技术测量了10种对加州南海岸空气盆地(SOCAB)生物量贡献较大的本地植物的碳氢化合物排放。从某些芳香鼠尾草和鼠尾草中观察到樟脑、桉脑和其他含氧碳氢化合物的大量排放。使用围栏技术很难获得这些物种的代表性排放速率测量结果。从2月下旬到4月，黑鼠尾草工厂排放的废气中，倍半萜所占比例很高。室内活橡树(Quercus Witlizenii)和灌丛栎树(Quercus Duosa)的异戊二烯排放速率低于大多数已检测的Quercus sp.然而，SOCAB中天然植物物种异戊二烯和萜烯的估计排放量表明，可能很难充分减少人为碳氢化合物，以达到臭氧的环境空气质量标准，并支持需要对氮氧化物和碳氢化合物进行严格控制的立场。
Hydrocarbon emissions from ten native plant species with high contributions to the biomass of California's South Coast Air Basin (SOCAB) were measured using a flow-through chamber enclosure technique. Camphor and cineole and other oxygenated hydrocarbons were observed to be large emissions from certain aromatic sage and sagebrush species. Representative emission rate measurements for these species were difficult to obtain using the enclosure technique. Sesquiterpenes were found to be a high proportion of the emissions from Black Sage plants from late February to April. The isoprene emission rates measured for Interior Live Oak (Quercus wislizenii) and Scrub Oak (Quercus dumosa) were lower than most previously examined Quercus sp. However, estimated emissions of isoprene and terpenes from natural plant species in the SOCAB suggest that it may be difficult to reduce anthropogenic hydrocarbons sufficiently to meet ambient air quality standards for ozone and support the position that stringent controls on NOxas well as hydrocarbons will be required.
