Air pollution tolerance indices of selected plants around Ulaanbaatar city, Mongolia
This study examined the air pollution tolerance index (APTI) of six plant species (two trees and four herbs) from Ulaanbaatar city (polluted site) and unpolluted area (control site). APTI values for Orostachys spinosa (L.) C. A. Mey., Larix sibirica Ldb., Picea obovate Ldb., Plantago depressa Willd....

| description | This study examined the air pollution tolerance index (APTI) of six plant species (two trees and four herbs) from Ulaanbaatar city (polluted site) and unpolluted area (control site). APTI values for Orostachys spinosa (L.) C. A. Mey., Larix sibirica Ldb., Picea obovate Ldb., Plantago depressa Willd., Chenopodium album L., and Taraxacum officinale Wigg. from unpolluted region were 9.35, 8.44, 9.29, 8.72, 7.98, and 8.13 and for plants from polluted region were 9.58, 9.5, 9.41, 9.33, 8.66 and 8.35 respectively. These results show that in cases where APTI increases from the control site to the polluted site, the species tolerance to pollution stress improves. However, all six species studied here had APTI values of less than 16 in both locations, which classifies them as pollution sensitive plants, although they differed from each other by the percentage of increase in APTI between sites. The result showed an order of tolerance with P. obovata (1.85%) > O. spinosa (2.58%) ³ T. officinale (2.58%) > P. depressa (7.01%) > C. album (8.59%) > L. sibirica (12.89%). Therefore, such species as L. sibirica, P. depressa, C. album are more sensitive compared with other species, and we can use them as bioindicators of air pollution stress. P. obovata, O. spinosa, T. officinale are relatively more tolerant compared with other species. |
