Detection and Semiquantitative Estimation of Chlorinated Organic Pesticide Residues in Foods by Paper Chromatography*

Removal of DDT, malathion, and carbaryl from tomatoes by commercial and home preparative methods

“…Analytical Methods. The procedure used in both laboratories for the extraction and clean-up of DDT was essentially that of Mills (1959). Petroleum ether extracts were stored at reduced temperatures until Florisil column clean-up and analysis by electron-capture gas liquid chromatography.…”

Insecticide Residues, Estimation of Insecticide Residues in Foods through Parallel Screening Methods

“…However, the analytical system is equally applicable to other crops and insecticides, if results are adjusted for masking effect. When control crops are not available or crop standards-as shown in Table IV-have not been developed, general MF values of 5 for chlorinated organics and 3 for organophosphates have been found widely applicable. The product for DDT in peas.…”

Resíduos de Pesticidas Organoclorados em Alimentos Gordos — revisão da metodologia analítica, II. Processos de purificação

“…São sobretudo os resíduos de pesticidas organoclorados oxigenados (dieldrina, endrina e heptacloro epóxido) que apresentam maiores problemas de eluição. Assim, Mills [45] utilizando E.E. .…”
