Effects of cypermethrin on Allium cepa

Environmental Toxicology, 2011
AbstractIn this study, toxic effects of the cypermethrin in Allium cepa L. cells were investigated. For this aim, we investigated the changes in pigment contents, antioxidant enzymes, mitotic index and chromosomal abnormalities as indicators of toxicity. The seeds were treated with different doses (1.5, 3.0, 6.0 ppm) of cypermethrin for 72 h.

Epimerization of Cypermethrin Stereoisomers in Alcohols

Journal of Agricultural and Food Chemistry, 2009
Isomerization induced by light, heat, and organic solvents has been shown to occur for some pyrethroid insecticides. Alcohols are popular solvents that are used in sample extraction, storage, and analysis. Thus, alcohol-induced epimerization may contribute to the incorrect interpretation of results from enantioselective chemical analysis and bioassay ...

Effects of cypermethrin, propetamphos, and combination involving cypermethrin and propetamphos on lipid peroxidation in mice

Environmental Toxicology, 2008
AbstractInsecticides are the chemicals widely used in agriculture, environmental health, human‐and animal‐health fields. Exposure to insecticides has been associated with many hazardous effects, including antioxidative metabolism. In the current study, the effect of cypermethrin (CYP), propetamphos (PRO) and their mixtures on oxidative stress in mice ...

Effect of alpha-cypermethrin and theta-cypermethrin on delayed rectifier potassium currents in rat hippocampal neurons

NeuroToxicology, 2009
Cypermethrin is a photostable synthetic pyrethroid and the most widely used Type II pyrethroid pesticide. The effects of two different stereoisomers of cypermethrin insecticides, alpha-cypermethrin and theta-cypermethrin, on the delayed rectifier potassium current (IK) in hippocampal neurons of rat, were studied using whole-cell patch clamp technique ...

Fate of cypermethrin in Malaysian oil palm plantation

Drug Testing and Analysis, 2020
AbstractCypermethrin is a pyrethroid insecticide commonly used to control bagworm infestation in oil palm plantations. It is applied through spraying onto the leaves where the bagworms reside. This article reports the fate of cypermethrin used in a Malaysian oil palm plantation during a typical dry season through the analysis of cypermethrin residue in

Cadmium potentiates toxicity of cypermethrin in zebrafish

Environmental Toxicology and Chemistry, 2015
Abstract Co-occurrence of pesticides such as synthetic pyrethroids and metals in aquatic ecosystems raises concerns over their combined ecological effects. Cypermethrin, 1 of the top 5 synthetic pyrethroids in use, has been extensively detected in surface water.

Nephrotoxicity of cypermethrin in rats. Histopathological aspects.

Histology and histopathology, 2020
Cypermethrin (CYP) is an important type II pyrethroid pesticide widely used to protect crops against pests and insect infestations. However, its toxicity is a risk to both human health and the surrounding environment. The present study was conducted to investigate the nephrotoxic effect and histopathological changes caused by Cypermethrin in the kidney

Stereoselective Degradation Kinetics of Theta-Cypermethrin in Rats

Environmental Science & Technology, 2006
The enantioselective degradation and chiral conversion of theta-cypermethrin (TCYM) in rats have been studied via intravenous (i.v.) injection. The degradation kinetics and the enantiomer fraction (EF) were determined by means of normal-phase high-performance liquid chromatography (HPLC) with diode array detection (DAD) and a cellulosetris-(3,5 ...
