| 英文摘要 | A quantitative comparative analysis of PM accumulation on boles, branches and leaves is necessary to better understand the reduction of airborne PM by trees. This study compared the total water-insoluble particle accumulation mass per unit area, the distribution of water-insoluble particle size fractions, and the accumulation masses and compositions of water-soluble ions among different vegetative organs. The average accumulation capacity of water-insoluble particles was as follows: leaf epicuticular wax (11.1 +/- 4.4 mu g/cm(2)), leaf surfaces (22.0 +/- 3.2 mu g/cm(2)), terminal branch surfaces (101.6 +/- 47.0 mu g/cm(2)), perennial branch surfaces (92.7 +/- 20.0 mu g/cm(2)), and bark surfaces (1719.9 +/- 684.7 mu g/cm(2)). Bole bark surfaces tended to accumulate the largest proportion of large particles, averaging 88 +/- 4%. Branch surfaces and leaf epicuticular wax accumulated the largest proportions of fine particles, averaging 15 +/- 5%. The total masses of water-soluble ions were 18 +/- 10%, 33 13% and 32 +/- 6% of the total water-insoluble particles on boles, terminal branches and leaves, respectively. Leaf surfaces accumulated 2.2-6.0 times more SO2- 4 and NO- 3 than did branch and bark surfaces. (C) 2019 Elsevier Ltd. All rights reserved. |
