This study was conducted to evaluate the differences between the heavy metal contaminated and non-contaminated Artemisia princeps var. orientalis and Equisetum arvense in litter decomposition processes. The plant samples were collected from abandoned mine tailings and control sites in Cheongyang, South Korea. The abandoned mine tailings have high heavy metal concentration and low soil organic matter contents. The heavy metal contents of mine tailings were about 13 and 28 times higher in As and Cd, compared to those in control soils. Also, the contents of the Cr, Ni and Zn in mine tailings were about 3 to 6 times higher than those in control soil. Samples of two plant species from mine tailings have high heavy metal concentrations compared to those from control sites. The leaf of A. princeps var. orientalis and shoot of E. arvense collected from mine tailings have approximately 23 and 58 times more in As, and 25 and 11 times more in Cd. The mass loss rates of plant litter from mine tailings were slower than those from control sites. During the experimental period, the decomposition of A. princeps var. orientalis leaf from mine tailings and control site showed 50.4% and 65.7% mass loss on the control soil area, respectively. The decomposition of A princeps var. orientalis leaf from mine tailings and control site showed 31.6% and 57.5% mass loss on the mine tailings area, respectively. The decomposition of A. princeps var. orientalis stem from mine tailings and control site showed similar patterns with their leaf decomposition. The decomposition of E. arvense shoot from mine tailings and control site showed 77.8% and 89.3% mass loss on the control soil area, respectively. The decomposition of E. arvense shoot from mine tailings and control site showed 67.6% and 82.1% mass loss on the mine tailings area, respectively. Therefor, the higher contents of heavy metals showed slow decomposition. The results suggested that heavy metal contamination affected the plant litter decomposition processes. |
