Semicarbazide compounds have been used as pesticides or fungicides in agriculture and for chemical synthesis in industrial processes. With this method, one or the total amount of Semicarbazide in real samples can be detected within 6...

Two simple, sensitive, rapid, accurate and precise spectrophotometric methods were developed for the analysis of parts per million levels of widely used carbamate pesticide Carbendazim. The first proposed method A is based on the Oxidation followed by complex formation product with 2,2-Bipyridyl – Fe(III) to form orange colored chromophore exhibiting absorption maximum at 512 nm with apparent m...

Abstract Acetylcholinesterase (AChE) activity levels can be used as an indicator for AChE inhibition due to pesticide poisoning in bird species. We assessed the comparative brain cholinesterase level of five species inhabiting exposed croplands and Protected Area i.e. Deva Vatala National Park (DVNP), Bhimber by using a spectrophotometric method. ranged from 56.3 85.9 µmol/min/g tissue birds re...

In this paper, we present a smartphone-readable barcode assay for the qualitative detection of methyl parathion residues, a toxic organophosphorus pesticide that is popularly used in agriculture worldwide. The detection principle is based on the irreversible inhibition of the enzymatic activity of acetylcholinesterase (AchE) by methyl parathion; AchE catalytically hydrolyzes acetylthiocholine i...

The distribution of thiols in mixed SAMs can be determined in a straightforward manner from spectrophotometric titrations using a fluorescent probe. A plot of saturation concentration as a function of mole fraction provides information on the number of headgroups involved in binding.

This study delves into the accumulation of residues in liver tissue rats exposed to galoxyfop-R-methyl pesticide. The investigation also evaluates presence malondialdehyde (MDA), a lipid peroxidation (LPO) product, mitochondrial membrane, along with activity antioxidant enzymes catalase, superoxide dismutase (SOD), glutathione reductase (GR), and peroxidase (GP). further explores impact sophora...
