目的了解大连市近几年企业车间苯系物的污染现状,防止发生急慢性职业中毒和控制职业病危害。方法对2010~2013年间委托检测的164家企业的苯系物检测结果进行分析。结果 2010~2013年苯、甲苯、二甲苯、乙苯、苯乙烯的合格率均在98%以上,苯、甲苯、二甲苯的总检出率依次为7.02%、42.69%、32.04%;甲苯和二甲苯的总检出率高于苯的总检出率(P<0.01);2010~2013年甲苯每年的检出率高于苯的检出率(P<0.01);二甲苯每年的检出率也高于苯的检出率(P<0.01)。结论大连市近几年大多数企业都存在苯系物危害,甲苯和二甲苯作为有机溶剂使用较多,工人接触的多是低浓度苯系物,应重视低浓度苯系物对作业工人健康的影响,对企业加强监管,控制急慢性苯系物化学中毒的发生。
Objective To understand the status quo of benzene plant in Dalian workshop in recent years and prevent the occurrence of acute and chronic occupational poisoning and occupational hazards. Methods The analytical results of benzene products of 164 enterprises entrusted to test from 2010 to 2013 were analyzed. Results The pass rates of benzene, toluene, xylene, ethylbenzene and styrene from 2010 to 2013 were all above 98%. The total detection rates of benzene, toluene and xylene were 7.02%, 42.69% and 32.04%, respectively. Toluene and The total detection rate of xylene was higher than that of benzene (P <0.01). The annual detection rate of toluene in 2010-2013 was higher than that of benzene (P <0.01) The rate was also higher than that of benzene (P <0.01). Conclusion Most enterprises in Dalian City in recent years, the presence of benzene series hazards, toluene and xylene as an organic solvent used more workers are mostly exposed to low concentrations of benzene, should pay attention to low concentrations of benzene on the health of workers Influence, strengthen supervision of enterprises, control the occurrence of acute and chronic benzene series chemical poisoning.
