Abstract Two pieces of experimental plots planted with Chinese littleleaf box (Buxus microphylla) and Fatsiajaponica respectively plus another barren one as control plot were used for testing a burying disposal of aban-doned batteries to handle the heavy metal contamination through the absorption by plants. After the interiorpaste of abandoned batteries had been buried into the soil of those three experimental plots respectively, theeffects of absorbing heavy metals by plants were analysed by regularly detecting the residual contents of zincand etc. that were usually abundant in batteries as tracers in the soil. The findings showed that Chinese littleleafbox could well absorb the elements of buried heavy metals whilst Fatsia japonica could not do obviously.
