以上诸方法均有优缺点,须要充分考虑,选择使用,同时更须注意采取比较简单检出法,如1.项之(1)(4)及化学法等是。人类的嗅觉,相当敏锐,例如挥发性很大的樟脑当它的浓度在1.16一1.29×10~(-9)克/1升时,一般体格正常青年立刻能嗅到,故1项(1)的方法检出,是有效的,如平时对多种毒气有充分经验者,利用此法,不但能定性出来,还可约略估计其含量。然因受外界的影响,臭气种类之不同,顷刻
Each of the above methods has its advantages and disadvantages, and it must be fully considered and selected for use. At the same time, more attention should be paid to adopting relatively simple detection methods such as 1. (1) (4) and chemical methods. The human sense of smell is quite acute. For example, when the concentration of volatile camphor is 1.16 - 1.29 x 10 -9 g/1 liter, young adults with normal physique can immediately smell, so 1 item (1) The detection of the method is effective, such as the usual experience of a variety of toxic gases, using this method, not only qualitative, but also a rough estimate of its content. However, because of the influence of the outside world, the type of odor is different.
