Other claims from this paper (13)
- Observation Rhododendron × pulchrum had the greatest PM retention (0.1082 mg/cm2) among the four shrub species.
- Observation Rhododendron × pulchrum had the highest accumulation of Cr, Mn and Ni in surface deposits and leaf tissues.
- Observation Rhododendron × pulchrum had the highest accumulation of As, Cd and Pb in surface deposits and leaf tissues.
- Observation Coarse particles (PM>10) dominated the PM distribution on the leaves of the four shrub species, at 71.60%.
- Observation PM2.5–10 made up 21.60% of the PM distribution, following the coarse fraction.
- Observation PM0.2–2.5 made up 6.81% of the PM distribution, the smallest fraction.
- Observation Buxus megistophylla showed superior capacity for fine particle (PM0.2–2.5) capture.
- Observation Photinia × fraseri showed elevated Hg levels (0.040 mg/kg).
- Observation Pittosporum tobira accumulated the highest Zn concentrations (36.041 mg/kg).
- Association Cu and Pb in P. tobira leaves were significantly correlated with the corresponding elements in leaf-associated PM (p < 0.05).
- Association Pb in B. megistophylla leaves was significantly correlated with the corresponding elements in leaf-associated PM (p < 0.05).
- Mechanism PM of different size fractions shows distinct selective adsorption patterns for atmospheric PTEs.
- Recommendation R. pulchrum is a promising understory shrub for greening in PTE-contaminated environments.
