“…Helicopter technique (single application) has the benefit of treating large areas with greater efficiency in a shorter time at relatively low cost. Many methods were published in the literature for the determination of residues of endosulfan and its metabolites in fruits and vegetables, [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] meat, 23 dairy and milk pro-ducts, [24][25][26][27] soil, 28,29 water [30][31][32][33][34] and plant and animal tissue. [35][36][37][38][39][40] The environmental fate and behaviour of the compound has been extensively studied.…”

A detailed study has been conducted to evaluate the residues of endosulfan and its principal metabolite (alpha-endosulfan, beta-endosulfan and endosulfan sulfate) which may have accumulated in environmental samples due to regular aerial spray application of endosulfan on cashew leaf plantation for a period of 20 years. Three months after the last spray of endosulfan 350 g litre-1 EC at 300 ml acre-1 (equivalent to 105 g AI acre-1 = 42.5 g ha-1), a total of 93 samples of cow milk, fish, water, soil and dried cashew leaf were collected from a village in Kasargode District, Kerala, India, where endosulfan contamination was likely to have occurred. All the samples were analyzed for total residues of endosulfan (comprising alpha- and beta-endosulfan), endosulfan sulfate and also the potential hydrolysis product endosulfan diol, using gas chromatography with electron capture detection. The minimum detection limits of total endosulfan was 0.001 microgram g-1. Analysis of soil samples showed the deposition of total endosulfan residues in the range < 0.001-0.010 microgram g-1, and dried leaf samples showed residues of endosulfan in the range < 0.001-3.43 micrograms g-1 dry weight. In cow milk, fish and water, endosulfan residues could not be detected above the minimum detection limit. Endosulfan diol was not observed in any sample. The data obtained was confirmed by GC-MS-EI using selective ion monitoring (SIM) mode.

“…Finally, it was tested in real samples for the potential application of the detector in real-life pesticide detection. As azinphos-methyl is widely applied in apple and tomato production, ,− we have prepared the apple and tomato juice extract and examined the sensitivity of azinphos-methyl detection in these juice solutions. The detailed procedure for the apple and tomato juice extract preparation is provided in the Supporting Information.…”

Detection of Pesticides in Aqueous Medium and in Fruit Extracts Using a Three-Dimensional Metal–Organic Framework: Experimental and Computational Study

A new, three-dimensional cadmium based metal-organic framework [Cd(PDA)(tz)Cl(HO)]·3HO {PDA = 1,4-phenylenediacetate and tz = 1,2,4-triazolate}, 1, has been successfully synthesized using slow diffusion method at room temperature. The structure of compound 1 has been determined using single crystal X-ray diffraction. The triazolate ligands connect three different types of octahedral Cd ions to form a two-dimensional structure. The chloride ion and PDA ligands connect the two-dimensional layers to form a three-dimensional structure. The phase purity of 1 was confirmed by powder X-ray diffraction, thermogravimetric analysis, and IR spectroscopy. Aqueous dispersion of compound 1 gives intense luminescence emission at 290 nm upon excitation at 225 nm. This emission was used for the luminescence based detection of pesticides, especially azinphos-methyl, chlorpyrifos, and parathion in aqueous medium. The selectivity of pesticide detection remains unaltered even in the presence of surfactant molecules. The mechanisms of luminescence quenching were successfully explained by the combination of absorption of excitation light, resonance energy transfer, and the possibility of electron transfer. Experimental findings are also well supported by the density functional theory calculations. Selectivity of pesticides detection in real samples such as apple and tomato juice has also been observed.

“…The organic chemical compounds of pesticides, most of them are dangerous and toxic. As a result of the decomposition of pesticides into toxic substances so that it is important to study their fate and know their behavior in terms of quantity and degradation on or in different plants (Neidert and Saschenbreker 1996). Pesticides used on agricultural for plants protection if its residue exceeds than the maximum permissible limits at harvest may cause poisoning of the people who consume these food products.…”

A Commercial acaricide etoxazole suspension concentrate (SC) formulation 10% under trade name dagrozoom was purchased from the Egyptian local market to study the etoxazole behavior in the field on green bean pods to estimate the pre-harvest period (PHI) and study the stability of etoxazole active ingredient under accelerator thermal storage conditions according to the food and agriculture organization (FAO) under different temperatures 35±2 о C for 90 days, 45±2 o C for 21days, 54±2 o C for 14 days and 72±2 o C for 5 days. Results indicated that suggested PHI for etoxazole according to the maximum residue limits (MRL) for green bean pods was 15 days from treatment and indicated also that etoxazole active ingredient was more stable and was conformity with FAO specifications when stored at 35±2 o C for 90 days, 45±2 o C for 21days and 54±2 o C for 14 days, on the other side the rate of thermal decomposition of etoxazole active ingredient was increased when stored at 72±2 o C for 5 days and became nonconformity with FAO after 3 days of storage.
