摘要
本文报道了某厂自1978～1987年在60余个汞作业点23494次汞蒸气浓度测定,结合316名接触汞的工人历年健康监护结果,证实汞接触水平与尿汞含量之间,以及神衰征候群、汞毒性细小震颤,口腔炎和精神症状与接触水平和持续接触时间之间均有接触反应关系。汞接触水平低于0.01mg/m^(?),接触10年无一例中毒病例发生,神衰征候群为20%;接触水平0.01～0.03mg/m^3,接触5年,汞中毒为2.0%(1/50),神衰征候群为49.2%(31/6(?));接触水平超过0.03mg/m^3,接触5年,汞中毒为18.2%(4/22),神衰症候群为81%(17/21).
Data obtained on 23494 measurements of mercury concentra-tion in the air of 60 worksites in a factory making clinicalthermometers and the annual routine medical surveillance re-cords of 316 employees from 1978-1987 were analysed.Resultof the analysis showed that the relationship between air mer-cury concentration,urinary mercury concentration,incidencesof neurasthenia,stomatitis,tremor and/or mercurialism to theexposure level and exposed duration were as follows(?)A.No mercurialism,but 20% neurasthenia on exposure tomercury below 0.01mg/M^3 for 10 years.B.2.0%(1/50)mercurialism and 49.2%(31/63)neurasthenia onexposure from 0.01 to 0.03mg/M^3 of mercury for 5 years.C.18.2%(4/22)mercurialism and 81%(17/21)neurastheniaonexposure to mercury above 0.03mg/M^3 for 5 years.
