Abstract

A simple and reliable method was improved to detect dichlorodiphenyltricholoroethane (p,p′-DDT) in river and fish pound water samples by using an automated solid phase microextraction (SPME) procedure (with a 0.1 mm polydimethylsiloxane fibre) and chromatographic analysis by gas chromatography-electron-capture detection (GC-ECD). The extraction time and carryover of the extraction were studied. The shorter equilibrium time and lower carryover between samples obtained by using automated SPME demonstrate that it is well to use fiber vibration instead of stir bars during extraction, Reproducibility achieved RSD values of <5% and standard addition was used for p,p′-DDT confirmation. The proposed method was applied to real water samples of aquatic culture areas.
