General Information:

A synthetic pyrethroid insecticide. It has a low aqueous solubility, is relatively volatile, is non mobile and, based on chemical properties, there is a low risk of it leaching to ground water. Lambda cyhalothrin is highly toxic to mammals and is a known irritant. It is also highly toxic to fish, aquatic invertebrates and honey bees. It is moderately toxic to earthworms. Lambda-cyhalothrin consists of one enantiomeric pair of isomers and is the more biologically active form of cyhalothrin

EPA/USP Method

USP Method 561: Determination of pesticides in articles of botanical origin by gas chromatography. Many botanicals are treated as dietary supplements and are subject to statutory provisions that govern foods, EPA Method EPA Method 1660 is applicable to the determination of pyrethrins and pyrethroids in municipal and industrial wastewater by extraction and high-performance liquid chromatography (HPLC) with an ultra-violet detector (UV). Separation and measurement of the pyrethrins and pyrethroids is performed by reverse-phase Cl8 column HPLC with a multiple-wavelength UV detector.
