Abstract
| - This study, which aimed to investigate the capacity of tea plant uptake and translocation of polycyclicaromatic hydrocarbons (PAHs), was divided into two sections. One was to study tea plant root uptakeof PAHs from water and translocation to leaves. The other was to research tea plant leaf uptake ofPAHs from air. It was observed that tea plant roots and leaves could strongly accumulate PAHs fromaround the environment. The capacity of tea plant uptake and translocation of PAHs were found tobe closely relative to the physical−chemical properties of PAHs. With the increase of lgKow (octanol−water partition coefficient) of the PAHs, both root concentration factors and leaf concentration factorsincreased exponentially, while translocation factors from roots to leaves decreased exponentially. Keywords: PAHs; tea; plant uptake; plant translocation
