Biomonitoring Equivalents for deltamethrin
Regulatory Toxicology and Pharmacology, 2011Measured concentrations of chemicals in blood or urine in biomonitoring studies provide an integrated reflection of exposures to chemicals via multiple routes and pathways. The potential significance of the measured concentrations of chemicals in the context of existing toxicology data and risk assessments can be assessed if chemical-specific ...

Polarographic determination of deltamethrin
Talanta, 1999The electrochemical characteristics of deltamethrin have been determined by means of electrochemical techniques such as d.c. polarography, cyclic voltammetry and differential pulse polarography over a wide range of pH from 2.0-12.0. The title compound exhibits a single well defined peak due to the reduction of the CC moiety present in deltamethrin. The

Photodegradation mechanism of deltamethrin and fenvalerate
Journal of Environmental Sciences, 2010To understand the degradation and environmental fate of pyrethroids, the process of their photodegradation under simulated natural conditions was investigated. The results showed that the degradation process follows first-order kinetics. The degradation intermediates were identified with gas chromatography-mass spectrometry.

Deltamethrin: Uses and Environmental Safety
1992Deltamethrin is a photostable pyrethroid providing valuable insecticidal activity against a large number of pests. Since it has potential uses for crop, cattle, and human health protection, extensive research work was done to evaluate its safety. Protection against insect pests in agriculture requires safety not only for applicators, but also for honey

Deltamethrin residues on Saskatoon berries
Journal of Agricultural and Food Chemistry, 1993Following four applications of deltamethrin [(S)-α-cyano-3- phenoxybenzyl (1R,3R)-cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropanecarboxylate], saskatoon berries were manually collected 1, 7, 14, 21, 28, and 39 days after the last application. Berries were stored frozen in foil-lined bags pending analysis.

Locust control with deltamethrin
1997The brown locust, Locusiana pardalina (Walker), is a chronic pest problem and a potential threat to the food security of some nine countries in southern Africa (Lea 1964). Intervention relies mainly on nymphal band control in the Karoo outbreak region of this locust species and involves the detection and direct spraying of bands with ground-based ultra

Deltamethrin Impairs Honeybees (Apis mellifera) Dancing Communication
Archives of Environmental Contamination and Toxicology, 2019As a commonly used pyrethroid insecticide, deltamethrin is very toxic to honeybees, which seriously threatens the managed and feral honeybee population. Because deltamethrin is a nerve agent, it may interfere with the nervous system of honeybees, such as dance behavior and memory-related characteristics.

Excretion of deltamethrin in lactating dairy cows
Food Additives and Contaminants, 1990A study was conducted to determine the metabolic fate of deltamethrin in lactating cows after a 'pour-on' application. Two cows were treated with 0.1 g deltamethrin and two with 1 g of the compound. Urine, faeces, milk and blood were collected over an 8-day period and analyzed for deltamethrin. This preliminary experiment has shown that it is necessary

Deltamethrin: The Cream of the Crop
Journal of Agricultural and Food Chemistry, 2010Replacement of the pyrethronyl alcohol portion of the natural pyrethrins with the 5-benzyl-3-furylmethyl moiety gave bioresmethrin, a synthetic pyrethroid of high potency and safety but with limited photostability. Introduction of novel substituents at the 3-position of the cyclopropane ring then led to the discovery of insecticidally active compounds ...
