摘要
环境中芳香胺主要来源于工业和非工业渠道。芳香胺对生物体的毒性主要是能够与DNA形成加合物,从而损害DNA。国际癌症研究机构(IARC)已公布了六种芳香胺是对人类的致癌物和可能致癌物。欧盟已将芳香胺列为在环境水中必须监测的优先控制污染物。由于环境中芳香胺含量很低,基质的干扰大,为提高其检出率和得到可靠的测定结果,需要对样品进行提取、富集,浓缩等前处理。本文介绍了目前应用在芳香胺测定中的离子对液液萃取(IP-LLE)、固相萃取(SPE)和固相微萃取(SPME)等样品提取、富集、浓缩技术。
Major sources of aromatic amines in the environment include industry and non - industrial sources. The toxicological properities of aryl amines are mianly characterized by their ability to form DNA adducts and to cause damage to DNA. Currently, the International Agency for Research on Cancer （IARC） classified six aromatic amines as a human carcinogenic or probably carcinogenic to humans. The European Union （EU） included many amines in the list of priority pollutants which should be monitored in environmental waters. Aromatic amines, in low concentrations in environment and the matrices of environmental samples, were often complex. To achieve low detection limits and reliable determination re- sults, prctreatment steps for sample extraction, enrichment, and concentration prior to analysis were very necessary. Several pretreatment sample techniques for the trace extraction, enrichment, and concentration of aromatic amines before their determinations, including ion - pair liquid - liquid extraction （ IP - LLE ）, solid - phase extraction （ SPE ）, and solid - phase microextraetion （SPME） were reviewed.
