Biomed Chromatogr. 1997 Jan-Feb;11(1):22-4. An HPLC procedure has been developed to follow the decay of malathion and methylparathion under control conditions using an mu-Bondapak C18 column with a mixture of acetonitrile and water to mobile phase and an ultraviolet detector for detection. |

J AOAC Int. 2006 Jul-Aug;89(4):903-12. Deionized water fortified with selected pesticides was extracted by using 2 types of SPE filtration disks (Empore C18 and Speedisk C18XF), and after extraction, the disks were incubated at 3 temperatures (25, 40, and 55 degrees C) and for 2 time intervals (4 and 14 days). In addition, some of the laboratories included 2 of the following pesticides: metolachlor, metribuzin, simazine, chlorothalonil, and malathion. |

Fresenius J Anal Chem. 2000 Nov;368(6):616-23. Two methods for the analysis of ten organophosphorus insecticides in natural waters using solid phase extraction disks containing C18 and SDB and solid phase microextraction fibers containing polyacrylate (PA) are developed. Bromophos ethyl, bromophos methyl, dichlofenthion, ethion, fenamiphos, fenitrothion, fenthion, malathion, parathion ethyl and parathion methyl were determined by GC/MS and GC/FTD. |

The pesticides studied, which have appeared frequently in actual cases, were endosulfan, lindane, parathion, ethyl-azinphos, diazinon, malathion, alachlor, tetradifon, fenthion and dicofol (o-p' and p-p' isomers). The extraction is performed by solid-phase extraction, with C18 cartridges and 2 internal standards, perthane and triphenylphosphate. |

Chem Pharm Bull. 1997 Apr;45(4):737-40. We have developed a simple and rapid method for measuring 11 organophosphorous pesticides (dichlorvos, methidathion, salithion, malathion, fenitrothion, fenthion, parathion, diazinon, ethylthiometon, O-ethyl O- phenylphosphonothioate (EPN) and chlorpyrifos) and one metabolite (3-methyl- of fenitrothion in serum and urine of acute poisoning patients by HPLC with a diode-array detector. An aliquot of the biological sample after deproteinization by acetonitrile was injected into C18 column using acetonitrile-water as a mobile phase. |

A rapid and effective method is developed for the determination of organophosphorus pesticides (dichlorovos, methyl parathion, malathion, and parathion) in underground water by solid-phase extraction (SPE)-gas chromatography-mass spectrometry. The use of Cleanert-PEP polymer SPE column improved higher extraction efficiencies than the C18 SPE column commonly used. |

J Chromatogr A. 2002 May 31;957(2):201-9. The first procedure involves solid-phase extraction using Sep-Pak Vac C18 disposable cartridges with for elution. The other procedure is based on liquid-liquid extraction with hexane-dichloromethane (1:1, v/v), followed by gas chromatographic analysis with effluent splitting to electron-capture detection for determination of endosulfan, captan, tetradifon and trichlorfon and thermionic specific detection for determination of malathion, parathion-methyl and monocrotophos. |

| 8694256 | Lacorte S, Barcelo D: Determination of parts per trillion levels of organophosphorus pesticides in groundwater by automated on-line liquid-solid extraction followed by liquid chromatography/atmospheric pressure chemical ionization mass spectrometry using positive and negative ion modes of operation. Anal Chem. 1996 Aug 1;68(15):2464-70. Liquid chromatography/atmospheric pressure chemical ionization mass spectrometry with positive and negative ion modes of operations was used for the trace determination of several organophosphorus pesticides, (E)- and (Z)-mevinphos, dichlorvos, azinphos-methyl, azinphosethyl, parathion-methyl, parathion-ethyl, malathion, fenitrothion, fenthion, chlorfenvinphos, and diazinon, in groundwater. This method required only 100 mL of water, and it was combined with a prior automated online liquid-solid extraction step using an OSP-2 autosampler containing C18 cartridges. |
