| Abstract: | Summary The residual levels of piperonyl butoxide (PB) in agricultural products were investigated for 531 samples of 10 species. For the determination of PB a high speed liquid Chromatograph equipped with a fluorometric detector was used. The detection limit of PB was 0.1 ppm. PB was detected from 3 barleys and 3 wheats harvested in U.S.A. ans Australia. It was not detected from the others. The residual range was from 0.2 to 1.4 ppm. |
