Canadian water quality guidelines for deltamethrin
Environmental Toxicology and Water Quality, 1998Canadian Water Quality Guidelines (CWQG) are numerical or narrative limits that protect designated water uses. Development of CWQG is based on review of deltamethrin's properties, uses, fate in the environment, ambient levels, accumulation in biota, and toxicity.

Permethrin and deltamethrin residues on lettuce
Pesticide Science, 1982AbstractPermethrin and deltamethrin, two synthetic pyrethroid insecticides, are registered in several countries for use on lettuce. Both chemicals were applied on autumn and spring grown lettuce in the glasshouse. When applied at the normal prescribed dose rates of 25 and 12.5 g a.i.

Chemical and photochemical isomerization of deltamethrin
Journal of Agricultural and Food Chemistry, 1990Chiral high-performance liquid chromatographic analyses have shown that deltamethrin [(S)-α-cyano-3-phenoxybenzyl(1R,3R)-cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropanecarboxylate] in natural water in the dark is subject to cis/trans isomerization yielding the α-S, 1S cis isomer 2'-deltamethrin, which is inactive against mice and insects.

Metabolism of deltamethrin in rats.
Biomedical and environmental sciences : BES, 2007To study the metabolism of 14C-deltamethrin in rats.Rats were dosed orally and i.p. with a single dose of 14C-deltamethrin (0.64 mg/Kg) body weight. The required dose was applied daily for 3 days. At the end of the experiment, selected organs, such as liver, kidney, fat, intestine, and blood were excised for radioassay of 14C-content.Deltamethrin was ...
