BACKGROUND Pesticides are extensively used worldwide to control plant pathogens and prevent agricultural product damage. However, they can pollute the environment and endanger human health. So far, a variety of sample preparation methods have been developed for pesticide residues analysis.

BACKGROUND In the last years, there is a concern about the presence of pesticides in honey since residues of DDT and carbaryl were found in honey samples. The traditional techniques, such as chromatography, reach the required limits of detection (LOD) but are not suitable for in‐situ implementation in honey packaging industry due to their high cost and the need of highly qualified staff for routine operation.

BACKGROUND Common bean is a staple food in Latin America and Africa, however, studies about contamination of common bean with pesticides are rarely reported. So, the goals of this study were to validate a multiresidue method and apply it in monitoring of pesticides in common beans. Extraction was performed applying QuEChERS approach to ground samples. C18 and PSA were used for clean‐up and a solvent exchange step was performed before injection into the GC–MS/MS.

ABSTRACT BACKGROUND A new type of deep eutectic solvent based on three components using phosphate salts has been synthesized, characterized, and applied in the extraction of eight organothiophosphate pesticides from honey samples. In the present study, the deep eutectic solvent was prepared from phosphocholine choline chloride as a hydrogen bond acceptor and dichloroacetic acid and decanoic acid as hydrogen bond donors.

Background In this study, the development of IR based‐prediction method for easy, fast and non‐destructive detection of pesticide residue levels measured by reference analysis in strawberry (Fragaria x ananassa Duch, Cv. Albion) samples using Near Infrared Spectroscopy (NIRS) and demonstrating its potential alternative or complementary use instead of traditional pesticide determination methods were aimed.

Background Fungicides are often applied to pears before kept in storage facilities. Scientific application of pesticides can reduce unnecessary exposure, which in turn could benefit both humans and the environment. Results We investigated dissipation behavior, residue distribution and conducted risk assessments for prochloraz, pyraclostrobin, and tebuconazole in pears stored under different conditions using ultra‐performance liquid chromatography.

BACKGROUND A new growing interest solvent named deep eutectic solvent has been prepared and used as an extraction solvent in the dispersive liquid–liquid microextraction method. In order to prepare the solvent, dichloroacetic acid, L–menthol, and n–butanol at a molar ratio of 4: 1: 1 are mixed and after heating the deep eutectic solvent is formed.

BACKGROUND The consumption of pesticides‐contaminated sour cherry as fruit or juice has become a major health concern, and thus, intensified the search for alternative processing technologies such as pulsed electric fields (PEF), ozone (O), and ultrasonication (US).

BACKGROUND Several diseases and insects may cause potential damage to the normal growth of cucumber. Azoxystrobin and meptyldinocap are effective against pathogens which have developed reduced sensitivity to other fungicides because of their novel mode of action. Azoxystrobin is persistent in various crops and environment. However, there is a lack of research on dissipation of these two pesticides, especially meptyldinocap.

Background excessive or improper use of organophosphorus pesticides (OPPs) may adversely affect human health through the food chain. In the present study, a simple, rapid, and effective analytical method was successfully established and used for the determination of OPPs quinalphos and its analogs in different food samples.

BACKGROUND Grape is an important fruit consumed either fresh or processed, therefore, fungicide misuse of grape has become an issue of global food safety and human health. Pyraclostrobin, and cyazofamid have been applied to grape frequently.

Abstract

BACKGROUND

Variability of pesticide residues among food items is very important when assessing the risks and food safety for the consumers. Therefore, the present study was undertaken to estimate the unit-to-unit residue variability factors for eggplant.

Abstract

BACKGROUND

Reduction of six pesticide residues (isoprocarb, chlorpyrifos, bifenthrin, beta-cypermethrin, difenoconazole and azoxystrobin) in cowpea by alkaline electrolysed water (AIEW) solutions with different pH was investigated. The commonly used washing treatments in household processing were used for comparison.

Abstract

Background

For developing countries like Thailand, regulation of pesticide usage exists but is not fully enforced. Therefore, pesticide residues in vegetables and fruits have not been well monitored. This study aimed to determine the pesticide residues in mangosteen fruits sold in Thailand. The mangosteen samples (n = 111) were purchased and the content of 28 pesticides were analyzed by GC-MS/MS method.
