研究了海桐（Pittosporum sinensis）和夹竹桃（Oleander）植物以及雅典两个主要公园土壤中的铅和镉浓度。两个公园的植被组成和密度显着不同。两种金属的浓度在外围区域明显较高，而在公园内部则逐渐降低。从外围到中心区域 60 m 的距离，这些值几乎达到了背景水平。植物和土壤污染程度与植被密度和结构、交通量、两种植物叶面性质和风速密切相关。 (C) 1997 Elsevier Science B.V.
The concentrations of Pb and Cd were studied in the plant species Pittosporum sinensis (Mock-orange) and Nerium oleander (Oleander) and in the soil of two major parks of Athens. The composition and the density of vegetation differs remarkably in the two parks. The concentrations of both metals were considerably higher at the peripheral zones and decreased towards the interior of the parks. At a distance of 60 m from the periphery to central zones the values almost reached background levels. The degree of plant and soil contamination was well correlated to the density and the structure of vegetation, the traffic volumes, the nature of the leaf surface of the two plants and the wind velocity.
