珠江三角洲地区重点VOC排放行业的排放清单

VOC emission inventory and its uncertainty from the key VOC-related industries in the Pearl River Delta Region

根据收集的珠江三角洲(珠三角)重点挥发性有机物(VOC)排放行业的活动水平数据,采用近年来VOC估算方面的研究成果及估算方法,建立了该地区2006年重点挥发性有机物排放行业和分城市的VOC排放清单.结果表明:珠江三角洲地区2006年重点挥发性有机物排放行业VOC排放总量为416.9kt,其不确定性(95%置信区间)为302.5～689.6kt(-31%～58%);家具制造业、建筑涂料使用、制鞋业是珠江三角洲重点VOC排放行业的主要来源,分别占总排放量的23.3%,21.2%和17.5%;东莞是珠江三角洲地区2006年重点挥发性有机物排放行业VOC排放量贡献最大的城市,其次是深圳,两者排放量分别占总排放量的23.6%和21.9%,主要的排放亦来源于家具制造业、建筑涂料使用与制鞋业.缺乏本地排放因子和良好的活动水平数据是本研究VOC排放量估算中主要的不确定性来源。

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.
