城市树木，特别是它们的叶子，具有捕获大气颗粒物(PM)和改善空气质量的潜力。然而，不同方法检测到的颗粒物在叶表面的沉积量差异很大，对颗粒物保留量与叶表面各种微观结构之间的关系的定量了解仍然有限。本研究采用叶洗法(LW法)、气溶胶再生法(AR法)和扫描电子显微镜与能量色散X射线能谱(SEM-EDX)法三种方法测定了3种针叶树种叶表面的PM保留量，并对不同采样点的叶片特征和PM元素组成进行了分析。结果表明，油松和冷杉是捕捉PM的有效树种，但不同的测量方法会影响叶表面PM累积的检测结果。不同地点间叶表面积累的微量元素浓度差异较大。元素在叶表面的积累量最大的是沈抚公路站点，暴露在PM污染水平较高的地方，而东岭公园站点的积累量最小。气孔密度和接触角与树种叶表面PM保留量高度相关(皮尔逊系数：r= 0.87，p<； 0.01，r= − 0.70，p<； 0.05)，而粗糙度和沟槽宽度相关性不显著(皮尔逊系数：r= 0.16，r= − 0.03)。这项研究表明，迫切需要一种测量PM的方法学标准化，这可能有助于选择具有高空气净化能力的绿化树种。
Urban trees, especially their leaves, have the potential to capture atmospheric particulate matter (PM) and improve air quality. However, the amount of PM deposited on leaf surfaces detected by different methods varies greatly, and quantitative understanding of the relationship between PM retention capacity and various microstructures of leaf surfaces is still limited. In this study, three measurement methods, including the leaf washing (LW) method, aerosol regeneration (AR) method, and scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM–EDX) method, were used to determine the PM retention capacity of leaf surfaces of three coniferous species.Additionally, we analyzed the leaf traits and elemental composition of PM on leaves collected from different sites. The results showed thatPinus tabulaeformisandAbies holophyllawere more efficient species in capturing PM thanJuniperus chinensis, but different measurement methods could affect the detected results of PM accumulation on leaf surfaces. The concentrations of trace elements accumulated on leaf surfaces differed considerably between different sites. The greatest accumulation of elements that occurred on the leaf surface was at the Shenfu Highway site exposed to high PM pollution levels and the smallest accumulation at the Dongling park site. The stomatal density and contact angle were highly correlated with the PM retention capacity of leaf surfaces of the tested species (Pearson coefficient:r= 0.87,p< 0.01 andr= − 0.70,p< 0.05), while the roughness and groove width were not significantly correlated (Pearson coefficient:r= 0.16 andr= − 0.03). This study suggests that a methodological standardization for measuring PM is urgently required and this could contribute to selecting greening tree species with high air purification capacity.Graphical abstract
