【摘要】 目的探索石雕作业对工人神经行为功能的影响。方法现场测定某石雕加工厂职业危害因素,并对石雕作业工人进行症状自评量表(SCL-90)调查和神经行为功能测试。结果石雕作业中产生的粉尘浓度为23.33~125.33mg/m3,呼吸性粉尘的构成比为66.0%~78.9%,噪声强度按Laeq(8)计为90.0~104.0dB(A)。SCL-90量表测试中,观察组在总分、总均分和7个因子上的得分均明显高于对照组;神经行为功能测试中,观察组在T、D、F和C等项目的得分显著增高,而在V项目上的得分显著减低。神经行为功能测试结果显示,与对照组比较,观察组在目标追踪、平均反应时等两个项目上的得分显著低于对照组(P<0.01)。结论石雕作业的粉尘及噪声危害较为严重,可导致工人神经行为功能的异常。更多还原

【Abstract】 Objective To research the occupational hazards on stone carving and effects on the neurobehavioral function of workers.Methods The occupational hazards survey was carried out in a stone carving plant,and the workers were tested by " SCL-90" questionnaire and neurobehavioral function test.Results The concentrations of dusk in the course of stone carving was 23.33 mg/m3~125.33mg/m3,and the ratio of respirable dust was 66.0%~78.9%.The noise intensity in Laeq(8)was 90.0dB~104.0dB(A).The total score,total average score and 7 factor scores in study group were significantly higher than that of the control group in the test of SCL-90 scale(P<0.05,P<0.01).The score of T,D,F and C items significantly increased and V item significantly decreased in study group compared with control group(P<0.01).In the meanwhile,the score of the items of target tracking and average response time significantly decreased compared with control group(P<0.01)in neurobehavioral function test.Conclusion The occupational hazards of dust and noise in stone curving work are serious,which can cause abnormal neurobehavioral function of workers.更多还原
