目的分析高密市制鞋行业苯及苯系物对作业工人的职业病危害情况,探讨其预防与控制对策。方法按国家职业卫生规范与标准,调查分析制鞋业苯及苯系物职业病危害现状,并对作业工人进行健康检查,对车间空气中苯、甲苯和二甲苯浓度进行监测。结果作业工人对职业卫生知识和职业卫生服务享受情况较低;对不同工龄组工人的舒张压、收缩压、白细胞、红细胞、血红蛋白、血小板以及丙氨酸转氨酶ALT活力均值进行比较,仅有血小板计数和ALT活力2项差异有统计学意义;对不同工种组工人的舒张压、收缩压、白细胞、红细胞、血红蛋白、血小板以及ALT活力均值进行比较,差异无统计学意义。结论苯及苯系物作业环境对工人的血小板计数和ALT活力有影响,并有随工龄增加而增高的趋势,但均未超出正常值范围。
Objective To analyze occupational hazards of workers and workers in benzene and benzene series in Gaomi footwear industry and to discuss their prevention and control measures. Methods According to the national occupational health standards and standards, the status quo of occupational hazards of benzene and benzene series products in footwear industry was investigated and analyzed. The workers in the workshop were inspected for their health and the concentrations of benzene, toluene and xylene in the workshop were monitored. Results The occupational health knowledge and occupational health services enjoyed by working workers were low. The diastolic blood pressure, systolic blood pressure, white blood cells, red blood cells, hemoglobin, platelets and alanine aminotransferase (ALT) activity of workers in different age groups were compared with only the platelet count There was no significant difference in ALT vitality and ALT vitality between two groups. The diastolic blood pressure, systolic blood pressure, white blood cell, erythrocyte, hemoglobin, platelet and average ALT activity of workers in different working groups were not significantly different. Conclusion The operating environment of benzene and benzene compounds has an impact on platelet count and ALT activity of workers, and tends to increase with the increase of working age, but they do not exceed the normal range.
