目的了解陶瓷粉尘接触工人心电图改变情况。结论对某生产卫浴洁具厂接触陶瓷粉尘车间的581位工人和非接触陶瓷粉尘车间的395位工人进行职业危害因素环境监测和预防性职业健康监护心电图检查并,并将结果进行对照分析。结果接尘组工作环境中空气粉尘浓度均超过国家标准限度;接尘组异常心电图改变显著(χ2=43.54,P<0.01),且随着接尘工龄的增加呈上升趋势,现患率由10.76%上升为35.21%;心电图改变主要以窦性心动过缓(χ2=22.53,P<0.01)为主,异常心电图改变主要集中在30～和40～年龄组(χ2=4.27,P<0.05),在性别上没有差异。结论工人长期接触陶瓷粉尘,可引起异常心电图改变,主要表现为窦性心动过缓,应引起卫生监管部门和企业的重视与干预,依法保障工人的身体健康。
Objective To understand the changes of electrocardiogram in workers exposed to ceramic dust. Conclusion A total of 581 workers in a sanitary ware factory that contacted the ceramic dust workshop and 395 workers in the non-contact ceramic dust workshop were monitored for environmental occupational hazards and preventive occupational health monitoring ECGs, and the results were compared and analyzed. Results The concentration of airborne dust in working environment of dust collecting group exceeded the limits of national standards. The abnormal electrocardiogram of dust collecting group changed significantly (χ2 = 43.54, P <0.01), and increased with the increase of service life, the prevalence increased from 10.76% (Χ2 = 22.53, P <0.01). The changes of abnormal electrocardiogram mainly concentrated in 30 ~ 40 years group (χ2 = 4.27, P <0.05) There is no gender difference. Conclusion Workers exposed to ceramic dust for a long time may cause abnormal electrocardiogram changes. The main manifestation is sinus bradycardia. Health authorities and enterprises should pay attention to and intervene in order to protect their health.
