摘　　要：目的了解莘县接尘企业工作场所接触粉尘浓度现状,评估接尘企业职业病危害因素的危害程度,为制定接尘企业职业防护规范及管理制度提供依据。方法于2022年2月,收集莘县疾病预防控制中心2017至2020年对89家接尘企业各接尘岗位的粉尘浓度监测数据,分析不同年度、粉尘种类和企业规模接尘企业的粉尘浓度检测合格率。结果2017至2020年共监测接尘企业89家,采集粉尘样品2132份,合格样品1818份,总合格率为85.3%。2017至2020年各年度粉尘检测合格率呈逐年增高趋势,分别为78.7%(447/568)、84.1%(471/560)、88.6%(418/472)和90.6%(482/532),差异有统计学意义(χ^(2)=36.27,P=0.003);矽尘(66.1%,41/62)、谷物粉尘(86.7%,1549/1786)、棉尘(84.1%,106/126)和木粉尘(77.2%,122/158)4种粉尘检测样品合格率差异有统计学意义(χ^(2)=29.66,P=0.002);大、中型企业粉尘样品检测合格率(95.1%,1194/1256)明显高于小型企业(71.2%,624/876),差异有统计学意义(χ^(2)=1584.40,P=0.001)。结论莘县接尘企业粉尘浓度检测结果合格率呈逐年上升趋势,小型企业粉尘浓度检测合格率较低,矽尘职业危害依然严峻。Objective In order to understand the dust concentration in the workplace of dust exposure enterprises in Shenxian.To evaluate the degree of occupational hazard factors of dust exposure enterprises.And provide basis for the formulation of occupational protection standards and management system of dust exposure enterprises.Methods In February 2022,the dust concentration monitoring data of 89 dust exposure enterprises from 2017 to 2020 by the Shenxian Center for Disease Control and Prevention were collected,and the qualified rates of dust concentration detection of dust exposure enterprises in different years,dust types and enterprise sizes were analyzed.Results A total of 89 dust enterprises were monitored from 2017 to 2020,2132 dust samples were collected,and 1818 qualified samples were taken,with a total qualified rate of 85.3%.From 2017 to 2020,the dust detection qualified rates showed a year-by-year increase trend,78.7%(447/568),84.1%(471/560),88.6%(418/472)and 90.6%(482/532),respectively,with statistically significant differences(χ^(2)=36.27,P=0.003).The differences in the qualified rates of dust detection samples of silicon dust(66.1%,41/62),grain dust(86.7%,1549/1786),cotton dust(84.1%,106/126)and wood dust(77.2%,122/158)were statistically significant(χ^(2)=29.66,P=0.002).The qualified rate of dust samples in large and medium-sized enterprises(95.1%,1194/1256)was higher than that of small-sized enterprises(71.2%,624/876),and the difference was statistically significant(χ^(2)=1584.40,P=0.001).Conclusion The qualified rate of dust concentration monitoring results of dust exposure enterprises in Shenxian showed an increase trend year by year,while the pualified rate of dust concentration monitoring in small-sized enterprises was low,and the occupational hazard of silica dust was still severe.
