摘要
目的了解电解铝行业职业病危害因素污染状况及对作业工人的健康危害。方法依据《工作场所有害因素接触限值》《尘肺病诊断标准》,对某铝厂电解铝车间空气中主要危害因素进行检测,对作业工人进行职业健康体检。结果2006年在铝厂电解车间设40个检测点,氧化铝粉尘CTWA为2.914.7 mg/m^3,超标率为62.5%;CSTEL为3.9-19.1 mg/m^3,超标率为67.5%。氟化物TWA为1.6-4.2 mg/m^3,超标率为50.0%;STEL为2.5-9.1 mg/m^3,超标率为55.0%。氟化物接触组尿氟均值为4.64 mg/L,对照组尿氟均值为0.58 mg/L,两者差异有统计学意义（P〈0.01）。结论氧化铝粉尘和氟化物对电解铝作业工人的健康影响比较严重,应引起有关部门的重视,加强电解车间作业工人的劳动保护。
Objective To understand the occupational hazards in electrolytic aluminum industry and health hazards for workers.Methods In 2006,risk factors in air of workshop for electrolytic aluminum were detected,and the workers were taken medical examinations for occupational health.Results 40 spots were set up in the aluminium electrolytic workshop,TWAs and STELs for dust of aluminium oxide were 2.9-14.7 mg/m^3 and 3.9-19.1 mg/m^3 at the exceeding rates of 62.5% and 67.5%.TWAs and STELs for alumina dust were 1.6-4.2 mg/m^3 and 2.5-9.1 mg/m^3 at the exceeding rates of 50.0% and 55.0%.Average values of urine fluorine between exposed group and control group were 4.64 mg/L and 0.58 mg/L,which had singnificant difference（P〈0.01）.Conclusion The impact of alumina dust and fluoride on affected workers are a little serious,related government departments should pay high attention and strengthen workers＇occupatioanl protection.
