Abstract
The content of Mn in barks of Xiangtan City was determined by Flame Atomic Absorption Spectrometry. The results showed that: (1) Xiangtan City belongs to the heavily polluted area of manganese. The average content of manganese in the bark is about 170 mg/kg and much higher than that of the background value of China (59.94±7.15 mg/kg). (2) The Mn content of the bark showed the status of Mn pollution in Xiangtan. Thus, The barks are proper for a biological monitoring carrier for heavy metal content in this area; (3) Different barks have different and stable accumulation capacity for heavy metals.
