目的探讨职业性慢性铅中毒的临床表现及流行病学分析。方法选取我院体检确诊与职业相关的慢性铅中毒的病例152例,测定血铅、尿铅等含量,进行健康状况调查。结果 1-10年工龄的患者,血铅含量为(610.7±29.3)μg/L;11-20年工龄的患者血铅含量为(669.1±34.6)μg/L;20-30年工龄的患者,血铅含量为(750.4±36.7)μg/L,随着工龄的延长,血铅含量逐渐递增,且差异具有统计学意义(P<0.05)。结论从事与接触重金属铅有关的行业的人群,随着工龄的增加,职业性慢性铅中毒的发病率增高,相关行业应提供健康工作环境,积极防治。
Objective To investigate the clinical manifestations and epidemiological analysis of occupational chronic lead poisoning. Methods A total of 152 cases of chronic lead poisoning confirmed by medical examination in our hospital were selected. The content of blood lead and urinary lead were measured and their health status was investigated. Results The blood lead level was (610.7 ± 29.3) μg / L in patients of 1 to 10 years of service, and (669.1 ± 34.6) μg / L in patients of 11 to 20 years of age. The patients with 20-30 years of service life, Blood lead content was (750.4 ± 36.7) μg / L, with the extension of service life, blood lead content gradually increased, and the difference was statistically significant (P <0.05). Conclusion With the increase of seniority, the incidence of occupational chronic lead poisoning is increasing in those engaged in industries related to heavy metal lead exposure. Relevant industries should provide a healthy work environment and actively prevent and treat such diseases.
