摘要：This study aims to assess the air pollution tolerance index of selected trees in major roadsides of Metro Manila. The air pollution tolerance index (APTI) of trees was assessed using the parameters: total chlorophyll, ascorbic acid, pH and relative water content. A total of 47 tree species were assessed in all major roadsides of Metro Manila. A number of trees observed were categorized as intermediate tolerant to air pollution. Significant differences on the APTI of the trees were evident depending on the species examined and had significant correlation to the locations of the major roadsides where they were collected (P < 0.05). Planting of trees, which are either tolerant or intermediate tolerant to air pollution, is necessary as these mitigate the effects of air pollution in the metropolis.
