Objective: The main objective of this study is to assess the potential of Ficus benjamina stomata to be used as indicators of local air pollution.
Methodology: Stomatal prints were taken from the species of study in the vicinity of roads, in residential and industrial areas and parks. Density, pore surface and stomatal resistance were determined from these prints. Stomatal density was higher in the potentially most polluted classes (roads, industrial areas) compared to less polluted classes (residential areas and parks). These last classes show much larger pores in less polluted classes than most polluted classes.
Conclusion and application of results: Stomatal leaf characteristics of Ficus benjamina can be great bioindicators of air quality. Specifically, stomatal density and pore surface could be potentially parameters for assessing air quality.

Keywords: Urban air pollution; stomatal characteristics; urban habitat;Côte d'Ivoire.
