Abstract:Based upon the collected activity data and newly available emission factors for the key VOC-related industries, a 2006-based VOC emission inventory from these sources was developed for the Pearl River Delta (PRD) region by source sectors and cities with the use of appropriate estimation methods. The total VOC emission from these sources in the PRD region was about 416.9kt, with uncertainty ranges of 302.5kt to 689.6kt(-31%~58%) on the 95% confidence interval; the furniture-making industries, building coatings use and shoe-making industries were the major key VOC-related industries emission sources contributor in this region, which shared about 23.3%, 21.2% and 17.5% of total VOC emissions from key VOC-related industries emission sources, respectively; Dongguan was the largest contributor in the key VOC-related industries emission sources and then Shenzhen, accounting for 23.6% and 21.9% of total VOC emissions in the PRD region, respectively, with both major sources as furniture and building coating use. Lack of local emission factors and well documented activity data was the major source leading to uncertainty in emission estimation.
