Abstract
Air and surface samples taken following indoor applications of natural pyrethrins and pyrethroids have been analyzed by HRGC‐ECD and HRGC‐MS using negative chemical ionization (NCI). It has been found that pyrethroids persist on surfaces as long as sixty hours after application.
Primary pyrethroid degradation products have been characterized by mass spectrometry; their identities and route of formation by ozonolysis have been verified by degradation studies and NMR.
