Paper Title:
Leaching Characteristics of Heavy Metals by TCLP Method in the Urban Soils of Quanzhou City
  Abstract

The available concentrations of heavy metals in the urban soils from different functional areas of Quanzhou city were determined using the toxicity characteristic leaching procedure (TCLP), developed by the United States Environmental Protection Agency (USEPA). The available concentrations of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Sn, Sb and Pb were 0.02–0.30, 0.02–0.20, 0.02–0.60, 14-500, 1.30-351, 0.10-2.40, 0.14-8.60, 0.30-50, 1.90-180, 0.06-0.60, 0.02-0.86, 0.02-8.0, 0.02-8.0 and 0.38-102 mg/kg, respectively. The extractable proportions of heavy metals were relatively low compared to their total concentrations, with the order of the extracted ratios of Cu (18.0%) > Mn (15.4%) > Ni (12.2%) > Sb (11.3%) > Zn (11.0%) > Cd (9.2%) > Co (8.9%) > Sn (3.6%) > Pb (3.1%) > As (1.9%) > Cr (0.8%) > Fe (0.2%) > V (0.1%) > Ti (0.0%).
