Liquid and Gas Chromatographic Multi-Residue Pesticide Determination in Animal Tissues

Sci. 1997, 49,56È64 Liquid and Gas Chromatographic Multi-residue Pesticide Determination in Animal Tissues Aurora Navas Dj az,* Angeles Garcj a Pareja & Francisco Garcj aSanchez Departamento de Qu•mica Anal•tica, Facultad de Ciencias, Universidad de Malaga, 29071-Malaga, Spain (Received 13 June 1995; revised version received 17 April 1996; accepted 16 August 1996) Abstract: A liquid chromatography multi-residue method with photometric detection has been developed. The method is applicable to the quantitative deter- mination of organochlorine (tetradifon, dicofol, chlorfenson, chlorobenzilate), organophosphorus (fenitrothion, azinphos-ethyl) and carbamate (pirimicarb) pesticides in animal tissues. The extracted residues are cleaned up by gel- permeation chromatography. A further fractionation on silica Sep-Pack car- tridges is included in the procedure. A gas chromatographic method with electron-capture detection for the analysis of the same pesticides was carried out and the results in the two cases compared. Lower detection and quantitation limits and similar recoveries of pesticides from spiked pig liver and brain samples were obtained by the LC method.

Multi-Residue Analysis of 210 Pesticides in Food Samples by Triple Quadrupole UHPLC-MS/MS
Multi-Residue Analysis of 210 Pesticides in Food Samples by Triple Quadrupole UHPLC-MS/MS David R. Baker1, Chris Titman1, Alan J. Barnes1, Neil J. Loftus1, Alexander Mastoroudes2, Simon Hird3 1Shimadzu Corporation, Manchester, UK 2Kings College London, London, UK 3Food and Environment Research Agency, York, UK Abstract Pesticides and their metabolites are of great concern to society as they are harmful to human health, pollute natural resources and disturb the equilibrium of the ecosystem. Consequently, stricter food safety regulations are being enforced around the world, placing pesticide analysis laboratories under increasing pressure to expand the list of targeted pesticides, detect analytes at lower levels and with greater precision, reduce analysis turnaround times, and all the while maintaining or reducing costs. In this study a method was successfully developed for the quantitation of 210 commonly analysed pesticides in food samples using the Nexera UHPLC and LCMS-8040. Initial validation was performed to demonstrate instrument capabilities. Limits of detection (LOD) for 90 % of compounds were less than 0.001 mg kg-1 (1 ppb) and all compounds were less than 0.01 mg kg-1 (10 ppb) for both the quantifying and qualifying transitions using only a 2 µL injection. Repeatability at the 0.01 mg kg-1 reporting level was typically less than 5 %RSD for compounds and correlation coefficients were typically greater than 0.997 in a variety of studied food extracts. Consequently, the LCMS-8040 is ideally suited for routine monitoring of pesticides below the 0.01 mg kg-1 default level set by EU and Japanese legislation.

Spatial Variation in Non-Target Effects of the Insecticides Chlorpyrifos
Pesticide Science Pestic Sci 55:875±886 (1999) Spatial variation in non-target effects of the insecticides chlorpyrifos, cypermethrin and pirimicarb on Collembola in winter wheat Geoffrey K Frampton* Biodiversity and Ecology Division, School of Biological Sciences, University of Southampton, Bassett Crescent East, Southampton, SO16 7PX, UK Abstract: Contiguous winter wheat ®elds of similar cropping history and soil type were used in a study of the responses of Collembola to summer sprays of cypermethrin and pirimicarb in southern England. Chlorpyrifos was included in the study as a toxic standard. Epigeic arthropods were captured by suction sampling and crop-inhabiting species obtained by dissecting wheat ears. Eight genera of Collembola responded signi®cantly to the insecticide treatments. Collembolan abundance decreased after chlorpyrifos was applied but increased after use of cypermethrin. Negative effects of cypermethrin and pirimicarb on Collembola were not detected in this study. Effects of chlorpyrifos varied spatially as a result of faunal heterogeneity among the ®elds, despite apparent homogeneity of the site. Some species known to be susceptible to chlorpyrifos were absent from one or more of the ®elds. The implications of these ®ndings for the interpretation of non-target pesticide effects and the potential use of Collembola as bioindicators in ®eld studies with pesticides are discussed. # 1999 Society of Chemical Industry Keywords: insecticides; chlorpyrifos; cypermethrin; pirimicarb; Collembola; side-effects; bioindicators -

Determination of Butocarboxim Residue in Agricultural Products by HPLC with Post-Column Derivatization System
Journal of Food and Drug Analysis 1999. 7(4) : 269-277 Determination of Butocarboxim Residue in Agricultural Products by HPLC with Post-Column Derivatization System SU-HSIANG TSENG*, PI-CHIOU CHANG AND SHIN-SHOU CHOU A method using high performance liquid chromatography (HPLC) for the determination of butocarboxim in agricultural products was developed. Butocarboxim was extracted from samples with acetone and the extract solution was concentrated. The residue was dissolved in sodium chloride solution and partitioned with n-hexane. The aqueous phase was collected fol- lowed by extracted with dichloromethane, which was then evaporated to a volume of 2 mL prior to passing through an aminopropyl cartridge for sample clean-up. Determination of butocarboxim residue in crops was carried out by HPLC equipped with a post-column deriva- tization system and a fluorescence detector. HPLC separation was performed on a Lichrospher 60 RP-Select B column eluted with a mobile phase of acetonitrile-water (25:75, v/v). Butocarboxim was hydrolyzed at 90°C under alkaline conditions and subsequently react- ed with o-phthaldialdehyde (OPA) / 2-mercaptoethanol reagent via a post-column reactor to generate a fluorophore, which was then detected with a fluorescence detector at Ex 340 nm and Em 455 nm. Average recoveries from radishes and bamboo sprouts, which were spiked with 0.1~0.3 and 0.2 ppm butocarboxim, respectively, were in the range of 81.9~82.6%. The detection limit was 0.05 ppm. No butocarboxim residue was detected in 10 commercial prod- ucts including radishes, carrots, and bamboo sprouts. Key words: agricultural products, butocarboxim, aminopropyl cartridge, high performance liquid chromatography (HPLC), post-column derivatization system, fluorescence detection. -
