Organophosphate pesticides: A general review
Pesticides are chemicals to control a variety of pests that can damage crops and livestock and reduce farm productivity. Organophosphate (OP) compounds are a group of pesticides that includes some of the most toxic chemicals used in agriculture. OP toxicity is due to the ability of these compounds to inhibit an enzyme, acetyl cholinesterase at cholinergic junctions of the nervous system. This r...
متن کاملDetermination of concentration of organophosphate pesticides
Pesticides are used extensively in agricultural lands in Northern provinces of Iran which makes river ecosystems more vulnerable to pesticides pollution. This study was conducted in three river estuaries (Babolrud, Tajanrud and Gorganrud), focusing mainly on the concentration levels of organophosphate pesticides (diazinon, malathion, azinphos-methyl) in the muscle tissue of golden mullet fish, ...
متن کاملOrganophosphorus hydrolase-based assay for organophosphate pesticides
We report a rapid and versatile organophosphorus hydrolase (OPH)-based method for measurement of organophosphates. This assay is based on a substrate-dependent change in pH at the local vicinity of the enzyme. The pH change is monitored using fluorescein isothiocyanate (FITC), which is covalently immobilized to the enzyme. This method employs the use of poly(methyl methacrylate) beads to which ...
متن کاملBiosensors for direct determination of organophosphate pesticides.
Direct, selective, rapid and simple determination of organophosphate pesticides has been achieved by integrating organophosphorus hydrolase with electrochemical and opitical transducers. Organophosphorus hydrolase catalyzes the hydrolysis of a wide range of organophosphate compounds, releasing an acid and an alcohol that can be detected directly. This article reviews development, characterizati...
