Dust has a size of 0.001 - 10000 µm. Dust from motor vehicle exhaust emissions generally has a size of 1 - 150 µm, and flying dust due to vehicle traffic has a size of 100 µm. This dust when it falls on the leaves will cover the stomata. The length of stomata is 80 µm and a maximum width of 50 µm, which is smaller than the size of the dust. As a result, the stomata will be covered by dust, and the leaves cannot absorb CO 2 , an important ingredient in photosynthesis. The leaf samples used in this study were Polyalthea Longifolia leaves located near the highway, around the cement factory, and in plantations as a control. Then, the leaves were measured for the content of total chlorophyll using the Wintermans and de Mots equation, and mineral content using X-ray Fluorencence (XRF). The results showed that the leaves around the cement factory had a yellow color, small, lower chlorophyll content, and had low absorptivity on minerals than the leaves from near the highway and control.
