The technological applications of nanoemulsions have increasingly been used in various applications due to their characteristic properties, small droplet size (in the range 20-200 nm) with high interfacial area, transparent or translucent appearance, high solubilization capacity, low viscosity, and high kinetic stability sedimentation, flocculation, and in some cases, the coalescence [1-3]. The influence of environmental pollution in plants can be seen from stomata in the leaves. The method of stomata observation was a replica method. This study was aimed to determine the characteristic of the mahogany leaf stomata in a polluted environment. One thousand fresh seeds (with wings) weigh from 607.06 g to 919.15 g. Significant differences existed between locality.
