South China Botanical Garden, Chinese Academy of Sciences, ChinaThe accumulation and allocation of pollutants in 8 one-year-old tree speeies seedlings were studied, which were planted in ceramic industry polluted area for one and half years. The results showed that S, Cu and Pb pollutants of soil were serious, while Ni, Zn, Mn and Cr pollutants were slight. Total dry mass per plant had significant differences among 8 tree species with a range from 198 g to 3248 g, and the mean of 1187 g. The contents of S and Pb changed greatly among different tree species and organs. The contents of S, Cu and Pb in 8 tree species ranged of 325-12541, 0.3-19.2, and 0.1-11.0 μg g-1, with the mean of 2459, 6.8, and 3.5 μg g-1, respectively, while their accumulation per plant ranged of 485-7008, 1.2-23.7, and 0.6-6.8 mg, with the average of 2367, 8.0, and 2.9 mg, respectively. The S accumulation per plant was in order as F. altissima>T. championi>F. microcarpa>P. heterophyllum>A. dioica>G. robusta>F. microcarpa var. fuyuensis>G. axillaris; Cu: F. altissima>T. championi>F. microcarpa>G. robusta>P. heterophyllum>F. microcarpa var. fuyuensis>A. dioica>G. axillaris; Pb: F. microcarpa>G. robusta>T. championi>F. microcarpa var. fuyuensis>P. heterophyllum>F. altissima>G. axillaris>A. dioica. It suggested that F. altissima, T. championi and F. microcarpa were suitable for phytoremediation in ceramic industry polluted area.
