摘要：

This work investigated concentration variability of anthropogenic halocarbons by performing four separate sample collections in urban, industrial, and back-ground atmospheric environments. Large concentration variability was found for CFC-12, CH3CCl3, CClH=CCl2, and CCl2=CCl2 in nonbackground environments. in comparison, the variability of CFC-113 and CCl4 was small regardless of the environments and was also close to the precision of the analytical system, implying that CFC-113 and CCl4 have relatively little emissions in Taiwan. The uniform property associated with atmospheric CCl4 is suggested as an "intrinsic" internal reference for quality control of VOC analysis.
