加油站作业场所常见污染因素污染水平研究

Common Pollutant Pollution Level Research in Gas Stations Workplaces

摘要: 文章中所采用的方法系GBZ/T系列的标准方法，选取周边地区16个规模较大的加油站及32个加油站工作人员进行试验，在加油站正常工作情况下，多点布设，采集作业场所空气中苯、甲苯、二甲苯、正己烷及溶剂汽油样品进行分析；分定点采样和个体采样两种方式进行评价。检测结果表明，16个加油站作业场所空气中及32个个体的苯、甲苯、二甲苯、正己烷及溶剂汽油的污染水平远低于标准《GBZ 2.1-2007工作场所有害因素职业接触限值第1部分：化学有害因素》的职业卫生接触限值。

Abstract: The methods used in this article are GBZ/T series of standard methods. 16 big scale gas stations and 32 workers around were selected as the test objects. When gas stations were in normal working condition, multiple points were set up, sampling air samples, then testing benzene, toluene, xylene, n-hexane and solvent gasoline content in the air samples. Sampling mode includes fixed-point sampling and the individual sampling. Results show benzene, toluene, xylene, n-hexane and solvent gasoline pollution level of the 16 gas stations and 32 workers were far lower than the standard limit of GBZ2.1-2007 “Workplace Harmful Factors of Occupational Exposure Limit Part 1: Chemical Hazardous Factors”.
