| 英文摘要 | Short-chain chlorinated paraffins (SCCPs) have attracted considerable attention for their characteristic of persistent organic pollutants. However, very limited information is available for their toxicokinetic characteristics, limiting the evaluation of their health risks. In this study, we performed a toxicokinetics study to explore the absorption and excretion processes of SCCPs (a mixture of C-10-, C-11-, C-12- and C-13- CPs) after a single oral administration to the Sprague Dawley rats. The toxicokinetic results showed that peak blood concentration of total SCCPs was attained at 2.8 day with C-max value of 2.3 mg L-1. The half-lives of total SCCPs in blood for the absorption t(1/2) (ka), distribution t(1/2) (alpha) and elimination phases t(1/2) (beta) were calculated to be 1.0,1.7 and 6.6 days, respectively. During the 28 days post-dosing, about 27.9% and 3.5% of orally administrated SCCPs were excreted through feces and urine without metabolism, respectively. Congener group abundance profiles indicate a relative increase of Cl-5-SCCPs in blood and urine in the elimination stage, and a higher accumulation of Cl8-10-SCCPs in feces. The distribution discrepancies of SCCPs congener groups in blood and excreta were more dependent on chlorine contents than on carbon chain lengths. (C) 2015 Elsevier Ltd. All rights reserved. |
