Biomonitoring Equivalents for deltamethrin

open access: yesRegulatory Toxicology and Pharmacology, 2011
Measured 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 ...

Toxicity of deltamethrin to Eriocheir sinensis and the isolation of a deltamethrin-degrading bacterium, Paracoccus sp. P-2

Chemosphere, 2020
Deltamethrin is used widely in Eriocheir sinensis aquaculture to remove wild fish and parasites. The residual deltamethrin greatly affects the growth and quality of E. sinensis. In this study, the LC50 of deltamethrin against E. sinensis at 24, 48 and 96 h was determined to be 6.5, 5.0 and 2.8 μg/L, respectively.

Effects of deltamethrin on lipid peroxidation in mice.

open access: yesVeterinary and human toxicology, 2002
Effects of deltamethrin on lipid peroxidation were investigated for subacute, subchronic and chronic periods. Deltamethrin was given to Swiss Albino mice at 1.5, 2.5, or 7.5 mg/kg. Lipid peroxidation was evaluated by determining malondialdehyde (MDA) levels in plasma, and determining glutathione peroxidase (GSH-Px), superoxide dismutase (Cu-Zn SOD) and

Polarographic determination of deltamethrin

Talanta, 1999
The 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, 2010
To 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: The Cream of the Crop

Journal of Agricultural and Food Chemistry, 2010
Replacement 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 ...
