摘要
目的了解某冶金行业酸洗等工种接触酸雾作业人员的健康状况,为制定防护对策提供依据。方法对某钢铁企业2001—2004年车间工作场所的H2SO4、HCl、HNO3、HF进行监测,并对作业人员健康状况进行调查。结果除H2SO4的2001年平均浓度超过国家标准外,其余各年度的各种酸雾均未超过国家标准;各工种作业人员牙齿酸蚀症检出率28.53%,且以酸洗工(34.84%)和蒸馏工(28.75%)检出率较高,与辅助工比较,差异有统计学意义;白细胞计数均值以酸洗工、防腐工较高,与蒸馏工和辅助工比较,差异有统计学意义。结论长期接触小剂量酸雾可引起作业人员牙齿酸蚀症和鼻甲肥厚,作业人员定期体检,并采取防护措施非常必要。
To learn the health status of the acid mist - exposed workers in the metallurgy industry and provide basis for establishing preventive countermeasures. [ Methods] Surveillance was carried out on H2SO4, HC1, HNO3 and HF on the worksites of a steal enterprise during 2001 - 2004; the workers＇health status was investigated. [ Results] The concentration of acid mist in every year didnt exceed the national standard except for that of H2SO4 in 2001 ; the detection rates of Dental Erosion and nasal conchae thickening were 34.4% and 34.93% respectively, which occurred mostly among acid -cleaning workers （33.75%） and the distillation workers （28.24% ）, the difference was significant compared with the auxiliary workers; the average leukocyte counting was high among the acid - cleaning workers and the antiseptic workers, the difference was significant compared with that among the distillation workers and auxiliary workers. [ Conclusion] Long- term exposure to small-dose acid mist can lead to Dental Erosion and nasal conchae thickening; regular physical examination and preventive measures should be carried out.
