Background and objective: Particulate matter (PM) is the most dangerous form of air pollution, and causes many diseases. Plants act as bio-filters to help reduce PM in the atmosphere. PM also influences the growth of plants, so selecting suitableplant species for specific environmental conditions is very important. The air pollution tolerance index (APTI) was used todetermine the tolerance level of each plant species to air pollution. The purpose of this study was to determine thetolerance to air pollution of various plant species in order to identify plant species that can be grown in pollutedenvironments; this was achieved by evaluating the APTI of plants. This study analyzed the biochemical parameters of 12plant species at two sites with different air pollution levels (urban forest and roadside) to assess and compare the APTI ofplant species. Methods: The healthy leaves of 12 plant species (6 broad leaves and 6 needle leaves) that are commonly used in landscapesin Korea were chosen for this study. The same plant species were collected from two sites with different pollution levelsand were analyzed immediately; one site was an urban forest (Chungcheongbuk-do Forest Environment Research Institute)with an area of 25 ha and featuring high vegetation coverage, while the other was at a high-traffic roadside next to acrossroads near the Cheongju Express Bus Terminal. We used the leaf samples to analyze four biochemical parameters ofeach plant: leaf extract pH (pH), relative leaf water content (RWC), total chlorophyll (TChl), and ascorbic acid. Finally, basedon these values, APTI values were calculated. Results: The APTI values were different between all 12 plant species at both sites with different levels of pollution. APTIhad a significant correlation with the biochemical parameters of plants. Plants in the urban forest and at the roadsideshowed APTI values ranging from 6.89-9.37 and 7.57-9.94, respectively. The APTI of the roadside plant species tendedto be higher than that of the plants from the urban forest. Among 12 plant species, Acer palmatum, Acer buergerianum,and Pinus densiflora had high APTI values. These plant species can serve as biofilters in environments with high airpollution. Conclusion: The APTI of the 12 plant species in this study can aid in the selection of suitable plant species fromenvironments with different levels of air pollution. The high APTI of some roadside plant species may show their toleranceunder environmental pollution-related stress, or demonstrate their adaptability to the polluted environment. In the future,we need to examine more plant species under various environmental conditions to understand their tolerance levels to airpollution and to correlate plants with air pollution. Further, more studies on other air pollutants that can influence plantgrowth, such as SO2 and NOx, should be conducted.

Background and objective: Particulate matter (PM) has a fatal effect on health. There have been many studies on the use of plants such as trees and shrubs as eco-friendly and sustainable biofilter for the removal of PM. In forming more green space, ground cover plants play an important role in multi-layered planting. This study was conducted to investigate the ability of plants to reduce PM, targeting Korean native ground cover plants with high availability in urban green spaces. Methods: For 4 species of Asteraceae, 4 species of Liliaceae, and 3 species of Rosaceae, one species of plants at a time were placed in an acrylic chamber (800 × 800 × 1000 mm, L × W × H) modeling an indoor space. After the injection of PM, the amount of PM remaining in the chamber over time was investigated. Results: For all three types of PM (PM10, PM2.5, PM1), significant difference occurred in the amount of PM remaining between plant species after 1 hour in the Liliaceae chamber, 3 hours in the Asteraceae chamber, and 5 hours in the Rosaceae chamber. With Liliaceae, the leaf area and the amount of PM remaining in the chamber showed a negative (-) correlation. With the Asteraceae and Rosaceae, there was a weak negative correlation between the leaf area and the amount of PM remaining in the chamber. Conclusion: When using ground cover plants as a biofilter to remove PM, it is considered effective to select a species with a large total leaf area, especially for Liliaceae.

Background and objective: Particulate matter (PM) has a serious impact on health. Recently, studies are conducted to reduce PM in an environmentally friendly way using plants. This study investigated the physiological responses of plants and their ability to remove PM by continuously spraying different PM sources (loam, fly ash, carbon black) to four native plant species, such as Iris sanguinea, Pteris multifida, Vitis coignetiae, and Viburnum odoratissimum var. awabuki. Methods: The four plant species were randomly placed in four chambers, and 0.1 g of different PM was injected into each chamber twice a week. We measured chlorophyll, carotenoid, chlorophyll fluorescence (Fv/Fm), total leaf area, amount of leaf wax, PM10 (sPM10) and PM2.5 (sPM2.5) on the leaf surface, and PM10 (wPM10) and PM2.5 (wPM2.5) on the wax layer. Results: For I. sanguinea and V. coignetiae, the sources of PM did not affect the growth response. P. multifida showed high chlorophyll a, b, total chlorophyll, and carotenoid content in carbon black as well as high Fv/Fm and total leaf area, thereby proving that carbon black helped plant growth. By PM sources, sPM10 showed a significant difference in three plant species, sPM2.5 in two plant species, and wPM10 in one plant species, indicating that sPM10 was most affected by PM sources. Conclusion: Carbon black increased the leaf area by affecting the growth of P. multifida. This plant can be effectively used for PM reduction by increasing the adsorption area. I. sanguinea and V. coignetiae can be used as economical landscaping plants since they can grow regardless of PM sources.
