Bottom Line: By determining the soluble ion concentrations of the airborne particulates in two regions, it is suggested that the soluble ion concentrations of PM10 in the atmosphere in the Botanical Garden and beside the Fifth Ring Road have significant differences, while those of PM2.5 in the atmosphere had no significant differences.In different polluted regions there are significant adaptive changes to the leaf structures, and when compared with slightly polluted region, in the seriously polluted region the epidermis cells of the plant leaves shrinked, the surface textures of the leaves became rougher, and the stomas' frequency and the pubescence length increased.Even though the plant leaves exposed to the seriously polluted region changed significantly, these plants can still grow normally and healthily.

ABSTRACT
Urban landscape plants are an important component of the urban ecosystem, playing a significant role in the adsorption of airborne particulates and air purification. In this study, six common landscape plants in Beijing were chosen as research subjects, and the adsorption capacities for each different plant leaf and the effects of the leaf structures for the adsorption capacities for particulates were determined. Preliminary results show that needle-leaved tree species adsorbed more airborne particulates than broad-leaved tree species for the same leaf area. Pinus tabuliformis exhibits the highest adsorption capacity, at 3.89 ± 0.026 μg·cm(-2), almost two times as much as that of Populus tomentosa (2.00 ± 0.118 μg·cm(-2)). The adsorption capacities for PM10 of the same tree species leaves, in different polluted regions had significant differences, and the adsorption capacities for PM10 of the tree species leaf beside the Fifth Ring Road were higher than those of the tree species leaves in the Botanical Garden, although the adsorption capacities for PM2.5 of the same tree species in different polluted regions had no significant differences. By determining the soluble ion concentrations of the airborne particulates in two regions, it is suggested that the soluble ion concentrations of PM10 in the atmosphere in the Botanical Garden and beside the Fifth Ring Road have significant differences, while those of PM2.5 in the atmosphere had no significant differences. In different polluted regions there are significant adaptive changes to the leaf structures, and when compared with slightly polluted region, in the seriously polluted region the epidermis cells of the plant leaves shrinked, the surface textures of the leaves became rougher, and the stomas' frequency and the pubescence length increased. Even though the plant leaves exposed to the seriously polluted region changed significantly, these plants can still grow normally and healthily.

Mentions: Figure 2 depicts the difference between the adsorptive capacities for particulates per unit of leaf area of different tree species. As shown in the ANOVA results in Figure 2, there is significant difference of the adsorptive capacities for particulates per unit of leaf area of different tree species, and the adsorptive capacities for airborne particulates of different leaves follow the order Pinus tabuliformis > Pinus bungeana > Salix matsudana > Acer truncatum > Ginkgo biloba > Populus tomentosa, among which the adsorptive capacity for particulates per unit of leaf area of the Pinus tabuliformis (3.89 ± 0.026 μg·cm−2) is the highest, that of Pinus bungeana (2.82 ± 0.392 μg·cm−2) is the second highest, and that of Populus tomentosa is the lowest, at 2.00 ± 0.118 μg·cm−2. The adsorptive capacity for particulates per unit of leaf area of Pinus tabuliformis is 1.94 times of that of Populus tomentosa. As can be seen from the comparison of the adsorptive capacities for airborne particulates of needle-leaved and broad-leaved tree species, the adsorptive capacity for particulates per unit of leaf area of needle-leaved tree species is higher than that of broad-leaved tree species, which is similar to the research results of the adsorptive capacities for airborne particulates on the leaves of different tree species from Norway and Finland reported by Sæbø, et al. [27], whose main result was the conifers may be the best choice for pollution-control planting.
