目的了解铅作业工人的血铅含量水平,为职业病防治提供科学依据。方法采用石墨炉原子吸收光谱法进行检测,按职业性慢性铅中毒诊断标准进行评价。结果 182名铅作业工人中血铅含量超过600μg/L,诊断值达到铅中毒水平的有3人,占1.7%,含量在400μg/L~600μg/L的铅中毒观察对象有19人,占10.4%,总体均值为221μg/L。男性的观察对象和铅中毒检出率及总体均值均高于女性。各工种观察对象和铅中毒的检出率,涂板、铸焊、铸板、组装、胶封等岗位明显高于后勤检验和充电包装岗位。结论铅作业工人存在职业危害,企业应采取有效的职业病防治措施,加强劳动者个体防护与职业健康监护,预防控制铅中毒职业病的发生。
Objective To understand the blood lead levels of lead workers and provide a scientific basis for prevention and control of occupational diseases. Methods The method was determined by graphite furnace atomic absorption spectrometry and evaluated according to the diagnostic criteria of occupational chronic lead poisoning. Results 182 lead workers had a blood lead level of over 600 μg / L and a diagnostic value of lead poisoning of 3, accounting for 1.7%. There were 19 lead poisoning patients with a lead content of 400 μg / L ~ 600 μg / L, accounting for 10.4 %, With an overall mean of 221 μg / L. Male subjects and lead poisoning detection rate and the overall average were higher than women. Various types of observation objects and the detection rate of lead poisoning, coated, cast welding, castings, assembly, sealing and other posts was significantly higher than the logistics inspection and charging and packaging positions. Conclusion Lead workers have occupational hazards, and enterprises should take effective prevention and treatment measures for occupational diseases, strengthen individual protection and occupational health guardianship, and prevent and control lead poisoning occupational diseases.
