To investigate whether leaves of plane trees (Platanus orientalis) are damaged by traffic pollution, trees from a megacity (Mashhad, Iran) and a rural area were investigated. Soil and air from the urban centre showed enrichment of several toxic elements, but only lead was enriched in leaves. Leaf size and stomata density were lower at the urban site. At the urban site leaf surfaces were heavily loaded by dust particles but the stomata were not occluded; the cuticle was thinner; other anatomical properties were unaffected suggesting that plane trees can cope with traffic exhaust in megacities.
为了研究悬铃木（Platanus orientalis）的叶子是否受到交通污染的损害，对来自大城市（伊朗马什哈德）和农村地区的悬铃木进行了研究。城市中心的土壤和空气中含有多种有毒元素，但只有铅在叶子中富集。城市地区的叶子面积和气孔密度较低。在城市地区，叶子表面被灰尘颗粒严重覆盖，但气孔没有被堵塞；角质层较薄；其他解剖学特性不受影响，这表明悬铃木可以应对大城市的交通废气。
