寒区部队居室苯并（a）芘调查报告

本文调查了寒区部队三市六个营区冬、夏、两季室内外苯并(a)芘的含量。结果表明,冬季室内外苯并(a)芘浓度0.00001～0.1796μg/100m~3,检出率100％;夏季0～0.0085μg/100m~3,检出率27.％8。一日内从早到晚呈上升趋势,但未超过参考标准(0.1μg/100m~3);旧营房居室分别是新营房的3.2、46.0和43.3倍。燃煤取暖的旧营房冬季是夏季的200多倍,提示燃煤取暖是苯并(a)芘含量增高的主要原因。

A Servey on B(a)P content of Barracks in Cold Region

This study reported that B ( a ) P determination was carried out in six barracks indoors and outdoors in Harbin, Changchun, Jinxi cities in winter and summer. The results showed; 1. the B ( a)P concentration was 0.00001-0.1796g/m3, detective rate was 100% in winter but o.0085g/m2 and 27.8% in summer. 2. the B ( a ) P concentration was gradually rising from morning to evening a day. However all of them remain whthin standard value. 3. the B ( a ) P concentration was 3.2, 46.0 and 43.3 times in old barracks as higher as new barracks respectively. 4.
