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，光化学氧化剂的增加趋势可能与未知挥发性有机物（VOCs）的存在有关。在本研究中，我将植物作为未知VOCs的排放源，并采用新的大气痕量组分分析方法--总OH反应性法对生物源VOCs进行了测定，结果表明，由于植物主要排放异戊二烯，因此我无法证实未知VOCs的存在。因为植物主要排放单萜，不幸的是我不能尝试OH反应性测量。但初步的GC-FID测定结果显示，其中含有多种单萜。这个结果暗示了未知物种存在的可能性。
