The stomata size and stomatal To 25 in 2010; nevertheless, youngsters density of B. papyrifera are certainly not counted mainly because leaf hair covered the stoma on leaf surface. Koelreuteria bipinnat has the highest groove proportion and stomata size, while the leaf hair and stomatal density of K. bipinnat are low. All of them do not show the highest PM2.5 capture capability. G. robusta is the most efficientbroadleaf species and C. lanceolate may be the most effective conifer with higher groove proportion and low stomata size. Species with high groove proportion and low stomata size is most helpful at capturing PM2.5. Earlier studies also reported that mounts of PM2.five captured on rough tree leaves with low stomatal density were high (Hwang et al. 2011; R en et al. 2013). Nguyen et al. (2015) discovered that trees with leaf hairs have higher PM2.5 capture capability. Species with densely haired leaves have been most productive at capturing PM (Dzieranowski et al., 2011; Weber et al. 2014). Nevertheless, we discovered no considerable correlation.LHb(mm-2) two.33 ?0.58Environ Sci Pollut Res (2016) 23:21176?LHt(mm-2) 2.33 ?0.58SD (mm-2) 37.21 ?three.18 8.84 ?0.SS(m) 75.67 ?7.59 12.33 ?1.14.17 ?2.08 20.33 ?3.06 43.00 ?8.54 63.33 ?11.60 11.19 ?two.81 0 0 0 15.64 ?1.12 132.67 ?15.42 6.67 ?1.51 12.47 ?2.36 13.81 ?three.04 17.01 ?3.41 23.66 ?three.79 13.77 ?1.27 21.05 ?2.14 3.86 ?0.85 0 0 0 0 6.33 ?1.52 0 6.66 ?0.58 0 7.00 ?1.00 0 0 0 0 0 12.67 ?1.53 title= cid/civ672 21.33 ?six.51 44.00 ?6.56 two.00 ?1.00 six.33 ?1.15 0 0 0 0 0 19.00 ?three.05 21.33 ?6.51 60.66 ?7.14 2.00 ?1.00 13.33 ?two.15 0 0 71.41 ?9.28 0 two.58 ?0.62 two.02 ?0.96 47.19 ?9.41 8.67 ?1.82 0 0 0 0 17.24 ?1.07 17.54 ?0.98 20.07 ?1.41 22.54 ?2.57 20.00 ?3.98 30.33 ?3.85 50.24 ?3.47 47.27 ?three.36.49 ?2.89 138.67 ?14.21.45 ?2.87 112.84 ?11.82 17.34 ?1.29 54.33 ?9.54 16.34 ?1.61 98.67 ?9.24 ten.78 ?0.75 192.47 ?17.44 14.21 ?0.85 87.33 ?6.87 13.47 ?1.98 18.52 ?1.07 38.36 ?3.02 18.74 20.11 16.93 15.87 title= journal.pone.0133053 ????32.33 ?5.24 20.00 ?3.98 80.12 ?6.Koelreuteria bipinnat 25.89 ?2.ten Coniferous Cunninghamia lanceolata 15.18 ?1.87 Beijing Broadleaf Pinus massoniana Broussonetia papyrifera Ginkgo biloba Platanus orientalis Magnolia soulangeana Populus tomentosa Fraxinus pennsylvanica Sophora japonica Coniferous Platycladus orientalis Pinus armandii Franch.
