2018年江苏省9 707名铅接触劳动者血铅水平分析

Blood lead levels of 9 707 occupationally lead-exposed workers in Jiangsu Province in 2018

    摘要
  • 摘要:
    目的 分析2018年江苏省铅接触劳动者血铅水平，为科学防护铅作业人群的职业健康提供合理建议。
    方法 采用横断面研究方法，收集2018年江苏省13个地级市9 707名职业性铅接触劳动者在岗期间血铅检查结果，并按照企业所在地区、经济类型和规模，以及工人工龄、性别等维度统计分析血铅异常值的分布规律。
    结果 血铅超标（血铅≥ 400 μg/L）者1 133人，超标率11.67%；其中疑似职业性慢性铅中毒（血铅≥ 600 μg/L）者120人，检出率1.24%。不同地区之间的血铅超标及疑似职业性慢性铅中毒检出率比较，差异有统计学意义（P < 0.05）。血铅水平、血铅超标及疑似职业性慢性铅中毒检出率均与年龄呈正相关关系（r=0.42、0.38、0.34，P < 0.05）；疑似职业性慢性铅中毒检出率与工龄无相关关系。不同经济类型、不同企业规模之间的血铅超标及疑似职业性慢性铅中毒的检出率不同（P < 0.01），其中私有经济、微型企业员工血铅超标检出率（14.70%、24.44%）及疑似职业性慢性铅中毒检出率（1.56%、5.56%）较高。男性血铅水平（185.2±155.8）μg/L，高于女性的血铅水平（123.2±128.6）μg/L（P < 0.01）；男性血铅超标和疑似职业性慢性铅中毒检出率均高于女性（P < 0.01）。
    结论 2018年江苏省铅接触劳动者血铅超标率较高，应加强对微型、私有经济企业以及高龄男性工人的重点关注。

     

    Abstract:
    Objective To analyze the blood lead levels of workers occupationally exposed to lead in Jiangsu Province in 2018, and to provide reasonable suggestions for scientific protection of lead-exposed workers' health.
    Methods The results of blood lead examination of 9 707 occupationally lead-exposed workers in 13 prefecture-level cities of Jiangsu Province in 2018 were collected. The distribution of abnormal blood lead values was analyzed according to the location (region), economic type and scale of enterprises, the workers' age, gender and exposure time.
    Results There were 1 133 workers whose blood lead were higher than national standard (blood lead >400 μg/L), accounting for 11.67%;120 workers were diagnosed as suspected cases with occupational chronic lead poisoning (blood lead ≥ 600 μg/L), accounting for 1.24%. There were significant differences among different regions of enterprises(P < 0.05). The level of blood lead, the exceeding rate of blood lead and the detection rate of suspected cases with occupational chronic lead poisoning were positively correlated with the workers' age(r=0.42, 0.38, 0.34, respectively). There was no positive correlation between the detection rate of chronic lead poisoning and the exposure time. The exceeding rates of blood lead and suspected cases with occupational chronic lead poisoning were different among different economic types and enterprise scales (P < 0.01). The exceeding rates of blood lead (14.70%, 24.44%) and suspected cases with occupational chronic lead poisoning (1.56%, 5.56%) were noted in private economy and micro enterprises. The blood lead level of male workers was (185.2±155.8) μg/L, which was higher than that of female workers (123.2±128.6) μg/L (P < 0.01). The exceeding rate of male blood lead and suspected cases with occupational chronic lead poisoning were significantly higher than that of female (P < 0.01).
    Conclusions The exceeding rate of blood lead of occupationally lead-exposure workers in Jiangsu Province was high, and the micro, private economic enterprises, and elderly male workers should be paid more attention.
