Chromatographic determination of herbicide residues in various matrices

Abstract

The newest results in the use of various extraction techniques and chromatographic methods such as gas-liquid and high-performance liquid chromatography used for the assessment of herbicide residues in various matrices have been compiled and critically evaluated. Practical employments in water and soil research, environmental protection, clinical and food chemistry are presented.

Binding of low molecular mass compounds to proteins studied by liquid chromatographic techniques

“…It was established that phenoxyacetic acid derivatives do not bind to egg albumin and the lipophilicity influences their affinity to bind to serum albumins. It was concluded from the results that the interaction of these herbicides with serum albumins involves hydrophobic binding forces occurring between the amino acid side chains of proteins and the apolar substructures of these herbicides (Cserháti et al, 2001b).…”

Critical Revision and Development Perspectives of Herbicide Residues Analysis in Agro Ecosystems

“…Because of the possible strong binding of herbicides to the polar or apolar components of soil and sediment, the use of an appropriate extraction and pre concentration method is the pre requisite of a reliable chromatographic analysis (Cserháti, 2004). The analysis of pesticides in solid environmental matrices, such as soil, sewage, sludge and sediments, has been addressed in much fewer occasions than in water, probably because of the comparatively greater complexity of the matrices and the absence of environmental quality standards (EQS).…”

Simultaneous Determination of Six Insecticides in Okra (Abelmoschus esculentus L. Moench) by UHPLC-MS/MS

“…These pesticides were used to prevent the destruction of edible crops by controlling agricultural pests or unwanted plants and thereby increases and improved food production [1].…”
