目的了解增城市制鞋企业职业卫生的基本情况,为做好今后的职业卫生防护工作提供参考。方法于2010年对增城市9个大中型制鞋企业,按照国家标准方法开展工作场所空气有毒物质监测,共设置79个监测点,每点均监测正己烷、苯、甲苯、二甲苯、丙酮、丁酮6个指标。结果 79个监测点,总超标率为20.25%,其中外资企业超标率为19.67%,民营企业为22.22%(P>0.05);所有监测点正己烷、丙酮、丁酮均符合国家标准要求,CTWA苯、甲苯、二甲苯的超标率分别为13.92%、10.13%、2.53%,差异有统计学意义(P<0.05);CSTEL苯、甲苯、甲苯的超标率分别为12.66%、7.59%、1.27%差异亦有统计学意义(P<0.05)。结论该年度增城市制鞋企业职业卫生状况不容乐观,主要的职业危害因素是苯、甲苯、二甲苯,职业卫生防护工作仍严峻。
Objective To understand the basic situation of occupational health in shoe-making enterprises in Zengcheng and to provide references for the future occupational health protection. Methods In 2010, 9 large and medium-sized shoe-making enterprises in Zengcheng City were monitored for airborne toxic substances in the workplace according to the national standard. A total of 79 monitoring points were set up. Each point monitored n-hexane, benzene, toluene, xylene, acetone, Butanone 6 indicators. Results The total over-standard rate was 20.25% in 79 monitoring sites, among which the over-standard rate of foreign-funded enterprises was 19.67% and that of private-owned enterprises was 22.22% (P> 0.05). All the monitoring sites of n-hexane, acetone and methyl ethyl ketone met the national standards, The over-standard rates of benzene, toluene and xylene were 13.92%, 10.13% and 2.53% respectively, with significant differences (P <0.05). The over-rates of benzene, toluene and toluene in CSTEL were 12.66%, 7.59% and 1.27% The difference was also statistically significant (P <0.05). Conclusion This year, the occupational health status of the shoe-making enterprises in Zengcheng City is not optimistic.
