Type: article
Abstract: This study focuses on the assessment of 2air pollution tolerance index (APTI) of 21plant species commonly found along roadsides in Ambo town, west showa, Ethiopia. The plants were evaluated in terms of APTI by analyzing four different biochemical parameters: leaf relative water content (RWC), ascorbic acid content (AA), total leaf chlorophyll (TCh) and pH of leaf extract. From Air pollution tolerance index (APTI) resultsit was noted that only two (9.52%) out of total 21 plant species designated as "Tolerant" and 9 species (42.85%) were designated as "Intermediate" and rest of the 10 species (47.61%) were categorized as "Sensitive".Highest air pollution tolerance index was found with Jacaranda mimosifolia (35.28) followed by Schinus molle (35.21) which were designated as "tolerant" species whereas least air pollution tolerance index was associated with Croton macrstachs (12.28) followed by Olea Africana (13.25) which are designated as "sensitive" species.Species with lower APTI value are considered sensitive species, which can be used as a biological indicator for further monitoring of air quality.Species with higher APTI value are tolerant species and thus, can be planted for pollution abatement in order to control and reduce environmental pollution.
