摘要

Monoterpenes in ambient air were determined in various sites in Guangzhou, and it was revealed that monoterpene concentration in some special sites, like landfills, were even higher than those in locations with much more vegetation. On the average, monoterpene con- tents in samples from streets and highways were 1.9μg/m~3; from gardens, plantations and wooded lands, 2.2μg/m~3; from farmlands, 1.5μg/m~3; but from landfills, 4.1μg/m~3.
