某钛白粉生产企业在岗职工职业健康检查结果

Occupation health examination results of workers in a titanium dioxide production enterprise

目的分析某企业集团纳米二氧化钛(钛白粉)生产作业工人的健康状况探讨钛白粉及其生产装置存在或产生的职业病危害因素对劳动者健康的影响。方法选择某企业集团从事钛白粉生产作业的工人199名作为暴露组,选取某能源公司116名管理工作人员作为对照组,通过对研究对象基本情况调查、钛白粉生产作业现场职业病危害因素调查、职业健康检查及普通健康检查等收集相关资料应用Excel 2003和SPSS 19.0软件包对数据进行录入和统计学分析。结果暴露组肺功能1秒用力呼气容积、用力肺活量(FEV_1、FVC)和FEV_1/FVC)低于对照组(P<0.05);肝功能中白蛋白、球蛋白、白球比与对照组比较,差异有统计学意义(P<0.05);两组尿常规检验结果显示,对照组尿比重均值略高于暴露组,而暴露组尿pH均值则高于对照组,差异均有统计学意义(P<0.05);血液分析情况比较:暴露组有115人存在1项以上血液指标异常,对照组为52人,分别占57.8%和44.8%,总体异常率及红细胞分布宽度变异系数、红细胞分布宽度、红细胞平均体积、平均血红蛋白浓度、红细胞压积、血小板分布宽度、平均血小板体积均值与对照组比较也有所差异(P<0.05)。结论钛白粉及其生产装置存在或产生的职业病危害因素对劳动者健康的影响是多方面的,钛白粉生产企业应有针对性地加强重点岗位职业病危害因素的治理和作业人员的个体防护。

[Objective]To analyze the health status of workers in nano titania（titanium dioxide） production enterprise,explore the effect of occupational hazard factors produced by titanium dioxide and its production equipments on the health of workers.[Methods]199 workers engaged in titanium dioxide production in an enterprise were recruited in the exposure group,and 116 workers engaged in management in an energy company were enrolled in the control group.The related data were collected by basic situation investigation,investigation of occupational hazard factors in titanium dioxide workplace,occupational health examination and general health check.Excel 2003 and SPSS 19.0 software package was applied in data entry and statistical analysis.[Results]The results of FEV_1,FVC and FEV_1/FVC in the exposure group were significantly lower than those in the control group（P〈 0.05）.There were statistically significant differences in the results of albumin,globulin and albumin-globulin ratio between the exposure group and the control group（P〈 0.05）.The routine urine test results showed that the level of urine specific gravity in the control group was slightly higher than that in the exposure group,while the pH value in the exposure group was higher than that in the control group,and the differences were statistically significant（P〈 0.05）.The blood analysis results showed that there were respectively 115 and 52 people with the abnormal results at least 1 index in the exposure group and the control group,which accounted for 57.8% and 44.8%respectively.There were statistically significant differences in total abnormal rate,red blood cell distribution width variation coefficient,red blood cell distribution width,mean corpuscular volume,mean corpuscular hemoglobin concentration,hematokrit,platelet distribution width and Mean platelet volume mean between the exposure group and the control group（P〈 0.05）.[Conclusion]There are multifaceted influences of occupational hazard factors produced by titanium dioxide and its production equipments on the health of workers.The enterprises should strengthen the control of occupational hazards in the key posts and improve the personal protection of exposed workers.
