塑胶产业作业场所醛酮类污染物释放水平研究

Research of Aldehydes and Ketones Pollutants Release Level in Plastic Industry in the 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10家生产规模较大的塑胶生产企业进行试验，在企业正常生产情况下，多点布设，采集空气中醛酮类化合物样品进行分析，结果表明，10家企业的空气中乙醛和异佛尔酮的污染水平远低于方法检出限及标准GBZ2.1《工作场所有害因素职业接触限值第1部分：化学有害因素》的限值要求，10家企业中有9家企业的丙酮和丁酮都未检出，其中一家丙酮丁酮有检出，但也远远低于标准GBZ2.1《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. 10 big scale plastic pro-duction enterprises around are selected as the test object. Monitoring sites and sampling under the condition of enterprise's normal production are determinate, then aldehyde ketone compounds are analyzed in the air samples. Results show: acetaldehyde and isophorone pollution level of the 10 enterprises were far lower than the method detection limit and the standard limit of GBZ2.1 “work-place harmful factors of occupational exposure limit Part 1: chemical hazardous factors”. Among them, 9 companies’ acetone and ethyl ketone were not checked out, one company’s acetone buta-none was checked out, but also far below the standard GBZ2.1 limits “workplace harmful factors of occupational exposure limit Part 1: chemical harmful factors” of occupational health exposure.
