Outline of Final Research Achievements

Using proton-transfer reaction mass spectrometry (PTR-MS), m/z 20 and 38 were found to originate from deuterium oxide. Sensitivity analysis showed that m/z 20 could provide lower detection limit. As humidity affect ion count rate of m/z 20, an equation was determined to correct the ion count for humidity. Water including deuterium oxide and organic compounds was supplied to soil in a potted tree and, using the equation, volatiles from the leaves were able to be monitored and the transportation speed of the compounds from root to leaf were determined. Using 13C toluene, we found that a larger amount of toluene was remained in the root and least partitioned to leaf. Larger abundance of 13C was observed in the dark respiration of the leaves, suggesting that some portion of the toluene was finally decomposed into CO2.
