Analytical Methods for Pesticides and Herbicides

Abstract

A review of literature published in 2010 on analytical methods for pesticides and herbicides is presented here in eight sections, including extraction methods, chromatographic or mass spectrometric techniques, electrochemical techniques, spectrophotometric techniques, chemiluminescence and fluorescence methods, sensors, biochemical assays and immunoassays, and miscellaneous techniques. Because many of the research studies in the cited publications utilized more than one analytical method, the different sections should not be thought of as being mutually exclusive.

Overview on Biosensors for Detection of Organophosphate Pesticides

“…Van Dyk & Pletschke [25] reviewed about the detection of organochlorine, organophosphate and carbamate pesticides in the environment. They focused on enzymatic methods as an alternative method for detection of these pesticides.…”

“…It was explained that these methods can serve as a tool for screening large samples which can be followed up with the more traditional chromatographic methods of analysis [10]. Liang & Hay [25] reported on literature published in 2010 about analytical methods for pesticides and herbicides including extraction methods, chromatographic or mass spectrometric techniques, electrochemical techniques, spectrophotometric techniques, chemiluminescence and fluorescence methods, sensors, biochemical assays and immunoassays, and miscellaneous techniques [25]. Rassaei et al [26] reviewed the state-of-the-art application of nanoparticles (NPs) in electrochemical analysis of environmental pollutants.…”

Study on an electrochromatography method based on organic-inorganic hybrid molecularly imprinted monolith for determination of trace trichlorfon in vegetables

“…During the last decade, many methods, including spectrophotometry, chromatography and chromatography–mass spectrometry, immunoassay, capillary electrochromatography (CEC) and biosensors have been reported for the determination of organophosphorus pesticides. Among them, CEC has attracted much attention since this technique shows great promise for analytical separation.…”

Synthesis and Evaluation of Organic–Inorganic Hybrid Molecularly Imprinted Monolith Column for Selective Recognition of Acephate and Phosphamidon in Vegetables

“…11 CEC, a technique that combines the high efficiency of capillary electrophoresis (CE) and good selectivity of LC, 12 has attracted much more attention as it is fast, efficient, and requires only a small amount of sample. Unfortunately, CEC has poor sensitivity especially with the UV detector, which is insufficient for direct determination of trace pesticide residues.…”

“…19,20 So, coupling MIT with CEC could take advantage of the high specific and good adsorption abilities of MIPs, and it is favorable to improve the separation efficiency and sensitivity of CEC simultaneously. 11,[21][22][23][24][25] Among the different MIP formats for CEC, monolithic columns show a promising prospect in the separation and detection field because they are easy to be prepared, provide for versatile surface modification, and have good permeability and peak capacity. Deng et al prepared a (S)-ibuprofen-imprinted monolithic column and it was capable of separating racemic ibuprofen.…”
