中文摘要	对我国4座生活垃圾焚烧炉飞灰样品中的二英分析结果表明,二英的毒性当量范围为0.34~3.80 ng/g.二英异构体的分布具有相似性,其中1,2,3,7,8-PeCDD和2,3,4,7,8-PeCDF共占毒性当量的33.6%~40.5%.结合对某生活垃圾焚烧炉长期监测结果,同一焚烧炉不同时期飞灰样品的二英毒性当量与1,2,3,7,8-PeCDD和2,3,4,7,8-PeCDF贡献值具有很好的线性相关性(r分别为0.996 3和0.997 4),1,2,3,7,8-PeCDD和2,3,4,7,8-PeCDF可作为指示异构体用于焚烧飞灰中二英毒性的快速测定,尤其适用于同一焚烧炉的长期监测,指示因子分别为4.466 4和3.164 6;不同焚烧炉飞灰的二英毒性当量与2,3,4,7,8-PeCDF有很好的线性相关性(r=0.984 9),2,3,4,7,8-PeCDF可作为不同焚烧炉飞灰中二英检测的指示异构体,指示因子为3.419 4.; Four municipal solid waste incinerator(MSWI) fly ash samples were analyzed for PCDD/Fs.The toxicity equivalent quotient(TEQ) was 0.34～3.80(ng/g.) The congeners distribution presented great comparability to each other as 1,2,3,7,8-PeCDD and 2,3,4,7,8-PeCDF contributed about 33.6%～40.5% of total TEQ.Combination with the published PCDD/Fs results of the long-term monitoring in MSWI fly ash in Shanghai,it was found that total TEQ had good correlation with 1,2,3,7,8-PeCDD and 2,3,4,7,8-PeCDF contribution(r=(0.996?3) and(0.997?4) respectively),so they could be considered as indicator isomers for the rapid determination of TEQ evaluation,especially in long-term monitoring of one incinerator.The indicator factors were(4.466?4) and(3.164?6) respectively.The analysis of the PCDD/Fs results from different incinerators also showed good correlation with 2,3,4,7,8-PeCDF contribution(r=(0.984?9)) and it could be considered as indicator isomer for TEQ evaluation of MSWI fly ash samples.The indicator factor was(3.419?4.); 国家自然科学基金项目(20277024); 国家高技术研究发展计划(863)项目(2002AA644010)
