以往用测定血δ-AlA-D活性、血铅、尿铅来了解一般生活环境下居民微量铅暴露程度。以上检验多数受检者不易接受。而唾液采集容易,因此用测定唾液铅浓度来反映环境中微量铅暴露状况,此法简单。取0.5ml唾液加入0.01NHNO_31ml将其pH值调至3～5ml,再加1ml1％吡咯烷二硫化氨基甲酸胺(APDC)螯合唾液中的铅离子,振搖30秒后再加甲基异丁基甲酮(MIBK)0.5ml,振搖30秒,离心10分钟(4500r/min),萃取,进行无焰原
In the past with the determination of serum δ-AlA-D activity, blood lead, urine lead to understand the general living environment of trace levels of lead exposure. Most of the above test is not easy to accept. The saliva collection is easy, so the determination of saliva lead concentration in the environment to reflect trace lead exposure, this method is simple. Take 0.5ml saliva added 0.01NHNO_31ml pH adjusted to 3 ~ 5ml, plus 1ml1% pyrrolidine disulfide carbamate (APDC) chelate saliva lead ions, shaking for 30 seconds and then add methyl isobutyl methyl (MIBK) 0.5ml, shaken for 30 seconds, centrifuged for 10 minutes (4500r / min), extraction, the flameless original
