ON-SITE MONITORING OF VOLATILE ORGANIC COMPOUNDS AS HAZARDOUS AIR POLLUTANTS BY GAS CHROMATOGRAPHY [Review]

摘要

There are a large number of organic components in air. These components can be classified in six groups. On-site monitoring procedures for two of these groups, oxidant precursors and hazardous air pollutants, are reviewed. For hazardous air pollutants, mainly long-term data are required. Oxidant precursors, however, some of which are very volatile, must be detected and quantified as early and as rapidly as possible. The monitoring techniques differ accordingly. Considerations governing on-site monitoring methods for both purposes are discussed. [References: 41]
