A Confirmatory Method for the Determination of Synthetic Pyrethroids in Wastewater

Synthetic pyrethroids are synthesized derivatives of naturally occurring pyrethrins, which are taken from pyrethrum, the resin extract of dried chrysanthemum flowers. They were introduced to provide a less hazardous and less persistent alternative to organochlorine and organophosphate insecticides. They are among the safest insecticides available on the basis of their low acute toxicity to mammals. Pyrethroid formulations are used in agriculture, animal husbandry, horticulture and in the home. They are extensively used for mothproofing woollen materials in the textile industry and as the active ingredient in commercial sheep dips.
