Air pollution tolerance index (APTI) is used by the environmental chemist to evaluate plant species that are tolerant to air pollution. Biochemical characteristics such as plant relative water content, pH, chlorophyll content and ascorbic acid of leaf tissue was determined in four sites. Manihot esculenta, Chromolaena odorata, Musa paradisiaca, Elias guinea, Helianthus, Psidium guajava, Imperata cylindrica, Mangifera, indica, Sida acuta and Centrosena pubescens are plant species used for the study. Three composites leaf samples growing near the sites were collected between three dates from October to December 2017. The obtained APTI values in all plant species exhibited tolerant characteristics with values ranging between 38.21 and 73.59. Results show that the APTI are relatively in the order; control.........................................................
