【求助】多环芳烃用气相测可参照EPA中的几号标准方法

楼主，先给一份英文的：
EPA 8100 Polynuclear Aromatic Hydrocarbons

下面两份是中文的：
8100多环芳烃类
8310多环芳烃类

还有别的吗？这两个我都看过，那pahs要求的回收率和含量标准在哪里查到

下面是摘自一篇官方文献，仅供参考：
PAHs are generally not produced commercially in the United States except as research
chemicals. However, PAHs are found in coal, coal tar, and in the creosote oils, oil mists, and
pitches formed from the distillation of coal tars. The National Institute for Occupational
Safety and Health (NIOSH) concluded that occupational exposure to coal products can
increase the risk of lung and skin cancer in workers. NIOSH established a recommended
occupational exposure limit, time-weighted average (REL-TWA) for coal tar products of
0.1 milligram of PAHs per cubic meter of air (0.1 mg/m3) for a 10-hour workday, within a
40-hour workweek. The American Conference of Governmental Industrial Hygienists
(ACGIH) recommends an occupational exposure limit for coal tar products of 0.2 mg/m3 for
an 8-hour workday, within a 40-hour workweek. The Occupational Safety and Health
Administration (OSHA) has established a legally enforceable limit of 0.2 mg/m3 averaged
over an 8-hour exposure period.
Mineral oil mists have been given an IARC classification of 1 (sufficient evidence of
carcinogenicity). The OSHA Permissible Exposure Limit (PEL) for mineral oil mist is
5 mg/m3 averaged over an 8-hour exposure period. NIOSH has concurred with this limit, and
has established a recommended occupational exposure limit (REL-TWA) for mineral oil mists
of 5 mg/m3 for a 10-hour work day, 40-hour work week, with a 10 mg/m3 Short Term
Exposure Limit (STEL).

我给楼主一个网址好象很全的，请参考！http://www.accustandard.com/asi/epa_downloads.php3

如果楼主做过PURG AND TRAP的工作 能否给我交流直到一下 。

谢谢上面的各位了，东西太好了
