英文摘要 | An agrochemical spreading agent was found near the slightly decomposed corpse of a deceased female. The appearance of the stomach contents suggested that ingestion of a surfactant had occurred before death. The spreading agent was found to contain nonionic nonylphenol ethoxylates (NPEO(n)) and anionic sulfonated naphthalene-formaldehyde condensates (SNFC(n)). A solid phase extraction cartridge containing a mixed reversed phase-weak anion exchange sorbent (Oasis WAX, Waters) was used to successfully extract both NPEO(n) and SNFC(n) from the blood. The cartridge was preconditioned with methanol and acetic acid (AcOH). After the dilute blood sample was applied to the cartridge, it was washed with AcOH, and then NPEO(n) and SNFC(n) were eluted with methanol/dichloromethane (7:3, v/v) and 5% NH(3)/80% methanol, respectively. The concentrations of NPEO(n=2-9) and SNFC(n=0) in the blood sample were 7.7 mu g/mL and 1.8 mg/mL, respectively. It is possible that postmortem changes increased the concentration of SNFC(n = 0) monomer by breaking down the polymer. However, the behavior of these compounds in the human body is unclear and further case studies are needed to investigate this result. (C) 2011 Elsevier Ireland Ltd. All rights reserved. |
