| 中文摘要 | Triolein embedded cellulose acetate membrane (TECAM) was used for passive sampling of the fraction of naphthalene, phenanthrene, pyrene and benzo[a]pyrene in 18 field -contaminated soils. The sampling process of PAHs by TECAM fitted well with a first-order kinetics model and PAHs reached 95% of equilibrium in TECAM within 20 h. Concentrations of PAHs in TECAM (C-TECAM) correlated well with the concentrations in soils (r(2) = 0.693-0.962, p < 0.001). Furthermore. concentrations of PAHs determined in the soil solution were very close to the values estimated by C-TECAM and the partition coefficient between TECAM and water (KTECAM-W). After lipid normalization nearly 1:1 relationships were observed between PAH concentrations in TECAMs and earthworms exposed to the soils (r(2) = 0.591-0.824, n = 18, p < 0.01). These results suggest that TECAM can be a useful tool to predict bioavailability of PAHs in field-contaminated soils. (C) 2008 Elsevier Ltd. All rights reserved. |
