通信作业环境挥发性有机物的定性分析与表征

摘要

To understand the sorts and pollution of volatile organic compounds in communication workshop for the basis of prevention and control, GC-MS technique was adopted to analyze the VOCs in the air of 10 typical workshops both in ground and underground stations. The results showed that 332 kinds of pollutants including benzene homologues, hydrocarbons, polycyclic aromatic hydrocarbons, organic acids, alkali, ester, aldehydes, ketones and heterocyclic compounds have been detected. The VOCs in communication workshops have lots of sorts and complex sources; their joint-action is probably a factor to influence health and working effectively.%了解通信机房作业环境挥发性有机物(VOCs)的种类和污染状况，为制定防治措施提供依据。利用气相色谱－质谱计算机联用系统(GC—MS)，对地面和地下共10个典型作业环境的VOCs进行了采集和全谱分析。结果表明，共检出332种污染物质，包括苯系物、脂肪烃、多环芳烃、有机醇、酮、胺、酯、羧酸及杂环化合物等。结论是，通信机房VOCs种类繁多、来源复杂，其联合作用可能是影响工作入员工作效率和身心健康的重要原因之一。
