Air pollution tolerance index (APTI) is used by landscapers to select plant species tolerant to air pollution. To develop the usefulness of plants as bioindicators requires an appropriate selection of plant species, which is of utmost importance in specific situations. In order to evaluate the tolerance level of plants to air pollutants, four parameters, namely ascorbic acid, chlorophyll, relative water content, and leaf-extract pH, were determined and computed together in a formulation signifying the air pollution tolerance index (APTI) of plants. The study examined the APTI of seven selected species which were fumigated with 60 ppb ozone gas (O3) for 10 days. The results showed that the APTI of Palaquium formosanum exhibited the most significant decrease after fumigation with O3. Based on the nature of their tolerance, the experimental plants could be arranged in tolerance order as Plaquium formosanum > Aglaia formosana > Cerbera manghas > Nageia nagi > Millettia pinnata > Terminalia catappa > Tournefortia argentea.
