Biomonitoring Equivalents for deltamethrin

Regulatory 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 ...

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: Uses and Environmental Safety

1992
Deltamethrin 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, 1993
Following 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.
