“…Maximum residue level (MRL) of methamidophos in vegetables is 1.0 µg g -1 for cauliflower and 2.0 µg g -1 for tomato [4]. Methamidophos having high solubility in water (200 g L -1 at 20 o C) may contaminate ground and surface water and pose potential threats to human health via drinking water and foods [2,3]. Due to its potential risk to human it is necessary to establish a selective and sensitive approach for determination of methamidophos in environmental samples.…”

ABSTRACT.A simple and rapid indirect spectrophotometric method for determination of methamidophos in water, soil and vegetable samples has been described. Methamidophos reacts with acid produced from pdimethylaminobenzaldehyde (p-DMAB) as a result of Cannizaro's reaction. The resultant adduct undergoes condensation reaction in acidic medium forming a yellow colored product. Absorbance of the colored product was measured at 405 nm and pH 3 against a reagent blank. The Beer's law range is obeyed in the range 1-30 µg mL -1 with molar absorptivity of 2.8 ×10 3 L mol -1 cm -1. The limit of detection and quantification were found to be 0.20±0.03 and 0.60±0.04 µg mL -1 respectively. The proposed method was effectively applied for determination of methamidophos in various samples with percent recoveries in the range of 96±0.08 to 102±0.06 %.

“…1A, is a highly efficient and broad-spectrum organophosphorus pesticide and is mainly used as an insecticide and acaricide. It has been widely applied around the world to control a number of pest insects such as trips, leaf hoppers, aphids, and spider mites, which are harmful to different plants such as fruits, vegetables, and other crops [1]. It has been reported that MAP with high solubility in water ([2 kg/L) and alcohol is chronically toxic in different test species and is sprayed with an average of preharvest at 0.5-1.5 kg/ha [2].…”

Methamidophos (MAP) is a highly efficient and broad-spectrum organophosphate pesticide. In this study, a rapid method for detecting MAP in vegetables using surface enhanced Raman scattering (SERS) spectroscopy has been established. Density functional theory calculations were performed with Gaussian 03 at RB3LYP level and with the 6-311G (d) basis set. SERS, normal and theoretical Raman spectroscopy were compared to investigate the mechanism of Raman scattering enhancement. The SERS signal of MAP was improved in alkaline conditions with optimum scattering efficiency at pH of 13.46. Furthermore, MAP detection in vegetables by SERS method had a good linear relationship between 0.01 and 1,000 lg/mL. The concentration of MAP in vegetables was detected and chosen for recovery test with three levels: 4, 8, and 15 lg/mL. The results of three level tests were 86.7-96.6 % and their relative standard deviations were between 1.2 and 2.5 %, which shows the good repeatability of this method.
