这项研究旨在展示巴西亚马逊森林地区单萜混合比例和通量的结果。它使用微气象仪器（使用声波风速计）和质子转移反应-飞行时间-质谱仪、PTR-ToF-MS 进行分析化学。使用含有不同质量的挥发性有机化合物的标准气体的重量混合物定期进行光谱仪的校准。结果表明，单萜平均混合比为0.185 ppbv，最大排放通量为1.495 mg m -2 h -1 。结论是，与亚马逊中部的另一个热带森林相比，该地区的单萜排放量显着，这证明需要改进对亚马逊流域不同森林的大气化学的研究。
This research aimed to present results about the mixing ratio and flux of monoterpenes at a forest region of the Brazilian Amazon. It was used micrometeorology instrumentation (using a Sonic Anemometer) and analytical chemistry by a Proton Transfer Reaction - Time of Flight - Mass Spectrometer, PTR-ToF-MS. The calibration of the spectrometer was performed regularly using a gravimetric mix of standard gas containing different masses of volatile organic compounds. The results showed average mixing ration of monoterpenes of 0.185 ppbv and maximum emission flux of 1.495 mg m -2 h -1 . It was concluded that this region presented a significant emission of monoterpenes in relation to another tropical forest in central Amazonia, evidencing the needing to improve studies about atmospheric chemistry in different forests of the Amazon Basin.
