“…Polarographic methods, using dropping mercury electrodes (DMEs), offer useful alternatives since they allow faster, cheaper and safer analysis (Somer and Dogan 2008;Inam and Cicek 2009;Sarigul and Inam 2009). Validation can be made by working with different electrolytes and at different pH values.…”

Melamine made headlines in September 2008 because it was found to be the contaminant responsible for the deaths of several infants and making many more sick. Determination of trace melamine is very important. Therefore, in this work a novel, sensitive and reliable method was developed using differential pulse polarography. The most suitable buffer system was found to be Britton-Robinson (B-R) buffer, pH 11.2. The melamine peak in this medium appeared at about −50 mV, it responded well to standard additions and high reproducibility was obtained. The calibration graph was linear in the concentration range of melamine from 1.0 to 66.4 μM with a correlation coefficient of 0.999. The limit of detection (LOD) and limit of quantification (LOQ) were obtained as 0.3 and 1.0 μM, respectively. The current was characterized as being adsorption-controlled process. The proposed method was successfully applied to the determination of melamine in spiked milk and milk powder. The linear dynamic ranges observed for melamine concentration in milk and milk powder samples were between 1-58 and 10-57 μM, respectively. The sufficiently good recoveries and low standard deviations for the data reflect the high accuracy and precision of proposed differential pulse polarographic method.

“…Yet, to ensure the increase in productivity of crops, farmers often use fertilizers, pesticides, and herbicides in excessive amounts. Indiscriminate usage of such agrochemicals should be avoided owing to their carcinogenic and mutagenic properties, and hazardous effects in human health and environment. , In addition to this, conventional agrochemicals have several disadvantages; application of these fertilizers in the soil causes an initial spike in concentration levels, but with time, it rapidly declines to below effective level, due to degradation, leaching, or volatilization of that compound. This phenomenon leads to repeated application of the conventional fertilizers, which eventually results in a decline in soil quality and eutrophication of nearby water bodies.…”

Excessive application of fertilizers negatively affects soil health, causes low nutrient utilization efficiency in plants, and leads to environmental pollution. The application of controlled-release fertilizer is gaining momentum to overcome this crisis. Engineered nanocomposites (ENCs) have shown tremendous promise for need-based delivery of agrochemicals (macro- and micronutrients, pesticides, and other agrochemicals). This review provides comprehensive coverage of synthesis of nanocomposites, their physical–chemical characterization, and techniques to achieve sustained release and targeted delivery to the crops, emphasizing their beneficial role in plant production and protection. Related aspects like feasibility of the application, commercialization of the nanoformulations, and biosafety concerns are also highlighted. This will be helpful to develop a critical understanding of the current state of the art in the controlled release of agrochemicals through nanocomposites. The pressing issues like scale up production, cost analyses, field-based trials, and environmental safety concerns should be given greater attention in future studies.

“…3 Sulfonylurea, diphenylether, and sulfonanilide herbicides were chromatographically separated using reversed-phase liquid chromatography-tandem mass spectrometry and selectively analyzed by MS/MS. 6 Some electrochemical methods such as differential pulse polarography (DPP), [7][8][9] square wave voltammetry (SWV) [10][11][12] or techniques involving biosensors 13,14 are also recommend for pesticide determination. However, a literature survey showed that no approach has been found for the square wave voltammetric behavior of aclonifen (Scheme 1) or its determination in soil, water samples and herbicide formulation.…”
