摘要: Laser ablation (LA) inductively coupled plasma mass spectrometry (LA–ICP–MS) has been applied to determine the nature of lead (Pb) distribution in plant tissues. Plants were cultivated hydroponically Hoagland medium supplemented with 0.5 mM Pb(NO3)2. After 96 h, parts root cut off from Pisum sativum and analysed. The difference amount Pb transported through vascular tissues was expressed as level signal intensity. Mapping vivo reveals metal pathway which may be particularly helpful understanding mechanisms heavy accumulation transport plant.
