Seasonal Variations of Monoterpene Concentrations in a Pine Forest in Florida, USA

Seasonal Variations of Monoterpene Concentrations in a Pine Forest in Florida, USA

In order to study the distribution characteristics of natural volatile organic compounds (NVOCs), we investigated the seasonal variations of $\alpha$-and $\beta$-pinene levels in a pine forest in Florida for a you. The mean concentrations of $\alpha$- and $\beta$-pinene measured during the whole study period were computed to be 125: 86 (N = 65) and 86$\pm$52 pptv (N = 56), respectively. According to our data grouping scheme, the seasonal means for both pinones were observed to peak during fall with their max and min values in summer and winter, respectively. The overall results of our study suggest that terpenes are subject to highly strong temporal variability because of changes in their major source characteristics across seasons.
