Abstract

We assessed the urban trees structure in Tabriz city and estimated the isoprene and monoterpenes emission using i-Tree Eco model. The results indicated that the i-Tree Eco model could be used as a successful method in Iran. Estimations of i-Tree Eco model showed that urban trees with 9.4% tree cover emitted 18428.6 and 49757.5 monoterpenes and isoprene during the year 2015. Open spaces and the ten tree species among the existing 48 species accounted for 63.3 and 92.22% of the total emission respectively. In the other hand White poplar and Austrian pin emitted the highest amount of isoprene and monoterpenes. Our results suggest that to plant the trees that emit fewer BVOCs in order to help to reduce the ozone level in cities. The results of this study could be used in proper urban environments and green infrastructure management.
