摘要

苯经常用于从个人取样器基底中提取收集的沥青烟雾。然而,由于其致癌性(国际癌症研究机构分类的第1组),这种溶剂特别危险。因此,为了防止实验室技术人员在从采样器中提取烟雾的过程中暴露于苯,必须找到一种折衷办法,以确定具有相同提取能力的毒性较小的溶剂。为了比较所选溶剂的提取能力,在实验室中从专用沥青烟雾采样器收集的三批不同的路面沥青中产生沥青烟雾。然后用苯和溶剂对样品进行萃取。在沥青和沥青烟雾分析研究中使用的11种毒性小于苯的溶剂中,正己烷和正庚烷被确定为苯的替代品。结果表明,正庚烷对三种沥青烟气的萃取效率与苯相当,且毒性较低,与苯置换具有较强的相容性,是苯置换的最佳候选溶剂。

Alternatives for Benzene in the Extraction of Bitumen Fume from Exposure Sample Media.

Benzene is frequently used to extract collected bitumen fumes from personal sampler substrates. However, this solvent is particularly dangerous because of its carcinogenicity (group 1 of the International Agency for Research on Cancer classification). Therefore, to prevent the exposure of laboratory technicians to benzene during the fume extraction step from samplers, a compromise had to be found to identify a less toxic solvent with the same extraction capacity. To compare the extraction capacities of selected solvents, bitumen fumes were generated in the laboratory from three different batches of road surfacing bitumen collected on dedicated bitumen fume samplers. The samplers were then extracted by benzene and the solvents tested. Of 11 selected solvents less toxic than benzene and used in studies on bitumen and bitumen fume analyses, n-hexane and n-heptane were identified as alternatives to benzene. In particular, the results demonstrated that n-heptane was the best candidate solvent for benzene replacement, due to its extraction efficiency comparable to benzene for the three bitumen fumes tested and its low toxicity, which is highly compatible with benzene replacement.
