目的了解无锡滨湖区近年来企业作业环境中混苯的检出情况,为辖区内苯系物所致急慢性职业中毒的防控工作提供依据。方法分析滨湖区疾病预防控制中心2008~2013年进行的企业作业环境苯系物检测数据。结果 2008~2013年滨湖区企业混苯超标率为12.02%(56/446);混苯检出率为32.62%(152/446);印刷、机械、其他3类行业混苯超标率分别为20.90%(28/134)、8.88%(15/169)、7.98%(13/163),3类行业间混苯超标率差异有统计学意义(X~2=932.00,P=0.000)。结论滨湖区企业作业场所混苯检出、超标情况仍较为常见,混苯职业性急、慢性中毒仍是我区今后的职业中毒的防控重点之一。
Objective To understand the detection of mixed benzene in the operating environment of enterprises in Wuxi Binhu District in recent years and provide the basis for prevention and control of acute and chronic occupational poisoning caused by benzene compounds in the area. Methods Binocular Disease Prevention and Control Center from 2008 to 2013 carried out in the operating environment of benzene plant detection data. Results In 2008-2013, the overbudding rate of mixed benzene in Binhu District was 12.02% (56/446); the detection rate of mixed benzene was 32.62% (152/446); the over standard rates of mixed benzene in printing, machinery and other three industries were 20.90% (28/134), 8.88% (15/169) and 7.98% (13/163), respectively. There were significant differences in the overbalance rates of mixed benzene among the three industries (X 2 = 932.00, P = 0.000). Conclusions The mixed benzene found in the workplaces of enterprises in Binhu District still exceeded the standard, and the occupational acute and chronic poisoning of mixed benzene is still one of the key prevention and control points of occupational poisoning in our district in the future.
