| determination of pesticide residues in fish tissues by modified quechers method and dual-d-spe clean-up coupled to gas chromatography-mass spectrometry. | the aim of this research was to modify the quick, easy, cheap, effective, rugged and safe (quechers) method for the determination of organochlorine and organophosphate pesticides in fatty animal matrices such as fish muscle tissues of carp and sturgeon collected from carp valley, lesser poland. pesticides extraction effectiveness was evaluated at 0.030 mg kg(-1) spiking level and efficiency of the dispersive-solid-phase extraction (d-spe) clean-up step was evaluated by comparison testing two dif ... | 2015 | 25074831 |
