Analysis Of Pesticide Residues By Polarography, Raymond J. Gajan

United States Food and Drug Administration: Publications

Polarography is a rapid, sensitive, and relatively specific technique that can be applied to pesticide residue analysis. The technique should also prove a valuable tool in overall pesticide research, such as monitoring new columns, studying kinetics, identifying and determining metabolites, assaying primary pesticide standards, and conducting stability studies.

Diphenylamine-Zinc Chloride As A Chromogenic Agent For The Detection Of A Mixture Of Ddt, Chlordane, And Toxaphene On Thin Layer Chromatograms, Lewis J. Faucheux Jr.

United States Food and Drug Administration: Publications

Diphenylamine-ZnCI, has been evaluated as a chromogenic agent for detection of toxaphene, DDT, and chlordane on Al₂O₃ a thin layer plates. Characteristic colors were obtained for these pesticides; a lower level of about 5 μg was detectable. Color reactions of 34 pesticides at the 20 μg level are presented.

Pesticide Residues, J. William Cook, Sidney Williams

United States Food and Drug Administration: Publications

METHODOLOGY for residue analysis has advanced rapidly during the current review period, from November 1962 through October 1964. Notable progress has been made in the development and refinement of methods of analysis by which any or all of a large number of pesticide residue chemicals can be detected and measured in one general operation. This is of particular significance because great interest has developed-outside the scientific community as well as within - in the possible presence of pesticide chemicals in all parts of our environment, including man himself. Only by the use of improved methodology will it be possible to …

Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

1. The nominate subspecies of E. granulosus (Batsch, 1786) is redesignated from the type locality, Europe.

2. Five subspecies of E. granulosus are described from South African carnivores: E. g. granulosus, E. g. africanus, E. g. felidis, E. g. lycaontis and E. g. ortleppi.

3. E. g. granulosus has so far only been recovered from the Transvaal; E. g. ortleppi appears to be restricted to the Transvaal; E. g. africanus occurs in the Orange Free State and the Transvaal; E. g. lycaontis and E. g. felidis like their definitive hosts are restricted to the Transvaal.

1965 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Beef carcass evaluation work is designed to obtain production and carcass data on bulls, steers and heifers. One objective is to evaluate sex effects on growth and carcass traits. Another is to determine if sires rank the same in growth and carcass traits on their bull, steer and heifer progeny.

Preliminary results from the 1963 slaughter groups were reported in the 1964 Beef Cattle Progress Report. This report covers averages of 1963 and 1964 results. Results both years were similar.
