Abstract | An analytical method is reported for the quantitiative determination of pydrin (fenvalerate) suitable for the detection of small amounts of this compound in flowing-water bioassays. The method utilizes the retention of pydrin on Sep-Pak C18 cartridges, subsequent elution and re-extraction, clean-up, and gas chromatographic analysis using capillary columns. By considering factors such as, sample size and instrument sensitivity, the limit of detection approached 0.02 micrograms of pydrin in seawater. |
