Abstract
The ease of employing proton-induced X-ray emission analysis (PIXEA) to studies relating metal content of soils to metal uptake in plants was aptly demonstrated in an investigation concerning the effect of automotive pollution on the abundance of about 16 elements accumulated in ribwort plantain and its surrounding soil. Elemental concentrations were shown to be dependent on the age of the plant leaves, as well as the distance from the roadside.
摘要
在一项关于汽车污染对车前草及其周围土壤中积累的约16种元素含量影响的调查中，充分证明了利用质子诱导X射线发射分析（PIXEA）研究土壤金属含量与植物对金属吸收之间关系的便利性。结果表明，元素浓度取决于植物叶片的年龄以及与路边的距离。
