It has been thought that the trend of the increment of the photochemical oxidant is probably related to the existence of the unknown volatile organic compounds (VOCs). In the present studies, I focused the plants as the emission source of the unknown VCOs, and measured the biogenic VOCs by the total OH reactivity: the new analysis method for the atmospheric trace species.As a results, I cannot confirmed the existence of unknown VOCs for the plants emits mainly isoprene. For the plants emits mainly monoterpenes, unfortunately I cannot try the OH reactivity measurements. But many kinds of monoterpenes are observed by the preliminary GC-FID measurements. This results implies the probability of the existence of the unknown species.

人们认为，光化学氧化剂的增量趋势可能与未知挥发性有机化合物（VOC）的存在有关。在目前的研究中，我将植物作为未知VCO的发射来源集中，并通过总OH反应性测量了生物源性VOC：大气痕量物种的新分析方法。作为A结果，我无法确认这些植物的未知VOC存在主要是EMITS EMITS。对于主要发射的植物，主要​​是单烯烯，不幸的是我无法尝试OH反应性测量。但是，初步的GC-FID测量值可以观察到许多单一类烯。这结果意味着未知物种存在的可能性。
