A simple and quick method for the determination of organophosphorus pesticides (OPs) in drinking water has been developed. After sample extraction with methylene chloride, analysis was directly carried out without further treatment using GC with a specific detector FPD on a DB-1701P column. A linear relationship between concentration and peak area was obtained within the range of 0.005 to 0.500...

The following article [1], doi: 10.3390/foods2010064, website: http://www.mdpi.com/2304-8158/2/1/64, has been retracted by the authors because of some major errors in broad field of pesticide residues identification and concentrations. During random cross check retention time of pesticides by HPLC did not match with the standards of detected pesticides. As a result concentration of all detected...

Glyphosate (N-phosphonomethyl glycine) is one of the most widely used pesticide around the world. It is very well known that glyphosate compound rapidly degrades into aminomethylphosphonic acid (AMPA) metabolite (Fig. 1). Glyphosate is a herbicide with a broad spectrum of activity, very effective even on plant roots with little harmful effects on mammals. Its high efficacy, low toxicity and aff...

Stanford Dependencies (SD) provide a functional characterization of the grammatical relations in syntactic parse-trees. The SD representation is useful for parser evaluation, for downstream applications, and, ultimately, for natural language understanding, however, the design of SD focuses on structurally-marked relations and under-represents morphosyntactic realization patterns observed in Mor...

A reversed-phase ion-pair HPLC method with ultraviolet detection has been developed for determination of metoclopramide (MCP) in bovine and swine muscle, liver, kidney, fat and intestine. MCP was extracted from samples with acetonitrile, and the extracts were cleaned up on an Oasis HLB cartridge (60 mg) after liquid-liquid extraction. The limit of detection of MCP was 0.002 microg/g and the lim...

Hazardous substances including persistent, bio-accumulative and toxic substances (PBTs), are chemicals which do not degrade easily in the environment. They typically accumulate in fatty tissues and are slowly metabolized often resulting in increased concentration through the food chain. Pesticides have also been used for breeding animals mainly to protect them from infestation of pests. The mai...

A competitive indirect enzyme-linked immunosorbent assay (ciELISA) using monoclonal antibodies (Mabs) having broad specificity for fluoroquinolone (FQ) antibiotics is described. Four FQs, ciprofloxacin (CIP), enrofloxacin (ENR), norfloxacin (NOR), and ofloxacin (OFL), were conjugated to bovine serum albumin for immunogens and to ovalbumin for coating antigens. A Mab C4A9H1 raised against the CI...

A rapid method has been developed for monitoring five multiclass pesticides commonly used in citrus fruits. The determination is performed by ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS), after extraction with a mixture of ethyl acetate and sodium sulfate. The method has been validated for orange matrix. Mean recoveries obtained were between 74-110% w...

Abstract The establishment of preharvest residue limits (PHRLs) is important to minimize damage producer and consumers caused by agricultural products which pesticide exceeds maximum (MRLs). Dissipation patterns acrinathrin metaflumizone in Aster scaber greenhouse were studied during 10 days order determine a pre-harvest interval after application. Acrinathrin applied two different greenhouse, ...

The present study aims at determining the level of contamination jawfish (Chrysichthys nigrodigitatus) by organophosphate residues in hydroelectric dams Faé, Kossou and Taabo. Ninety (90) fish were collected from these three during eight sampling campaigns. Composite samples formed, each for two fish. A total forty-five (45) composite formed. detection pesticide was determined gas chromatograph...
