| Abstract: | tmospheric CH3Br was trapped by Tenax adsorbent and was determined by gas chromatography with photoionization detector. The CH3Br concentrations in indoor and outdoor are 24 X 10-12 (V/V) and 77. 4 X 10-12 (V/V).The standard deviation and detection limit for the method are 0. 0521, 10 pg respectively. The level of CH3Br pollutions is 10--11 (V/V) |
