How to locate the zero time in a recorded, noisy waveform? How to quantify the extent of minimum‐phaseness of a waveform? And how to render a waveform or a seismic trace minimum phase? These are some of the questions with which we approached this p

Residues of lindane and its metabolites in eggs, chicks, and body tissues of hen pheasants after ingestion of lindane‐14C via treated wheat seed or gelatin capsules1
Autor: J G Saha, R H Burrage
Publikováno v: Journal of Environmental Science and Health, Part B. 11:67-93
Studies were carried out to investigate possible contamination of pheasants with residues of lindane used as seed dressings for the control of wireworms in cereal crops. One group of laying hen pheasants was fed 20 mg of lindane-14C in gelatin capsul

Comparison of Several Methods for Extracting Chlordane Residues from Soil
Autor: J G Saha
Publikováno v: Journal of AOAC INTERNATIONAL. 54:170-174
Residues of chlordane were extracted from a field-contaminated clay loam soil with various solvents under a variety of conditions. Mixtures of hexane-acetone and hexane-2-propanol recovered only 1.93–2.64 ppm total chlordane residues from the air-d

Insecticide Residues in Pheasants after Being Fed on Wheat Seed Treated with Heptachlor and 14C-Lindane1
Autor: J. G. Saha, R. H. Burrage
Publikováno v: Journal of Economic Entomology. 65:1013-1017
Different amounts of heptachlor-treated wheat seed containing 365 ppm heptachlor and 105 ppm trans -chlordane were fed to pheasants for different lengths of time, and residues in muscle, liver, brain and fatty tissues were determined at various times

Determination of the Herbicide Tordon (4-Amino-3,5,6- trichloropicolinic Acid) in Soil by Electron Capture Gas Chromatography
Autor: J G Saha, L A Gadallah
Publikováno v: Journal of AOAC INTERNATIONAL. 50:637-641
A method is presented for determining the herbicide tordon (4-amino-3,5,6-trichIoropicolinic acid) in soil. It involves extraction of tordon as the free acid with acetone and phosphoric acid, followed by esterification with diazomethane and estimatio

Residues of DDT, DDE, and DDD in Fish in the Saskatchewan River after using DDT as a Blackfly Larvicide for Twenty Years
Autor: J. G. Saha, F. J. H. Fredeen, L. M. Royer
Publikováno v: Journal of the Fisheries Research Board of Canada. 28:105-109
Concentrations of organochlorine pesticide residues in the muscle tissues of fish collected from the Saskatchewan River after a 20-year blackfly larviciding program using DDT ranged from less than 0.01–0.05 ppm of DDT, less than 0.01–0.05 ppm DDD

HEPTACHLOR, HEPTACHLOR EPOXIDE, AND GAMMA-CHLORDANE RESIDUES IN SOIL AND RUTABAGA AFTER SOIL AND SURFACE TREATMENTS WITH HEPTACHLOR
Autor: W. W. A. Stewart, J. G. Saha
Publikováno v: Canadian Journal of Plant Science. 47:79-88
The distribution of insecticide residues in soil and rutabagas, after soil and surface treatments with heptachlor, was studied by gas-liquid chromatography. Granular heptachlor at 6.6 kg/ha was incorporated into the top 1.27 to 1.90 cm of soil and he

Comparison of Several Solvents for Extracting Root-Absorbed Radioactive Dieldrin and Lindane Residues from Wheat Plants1
Autor: J. G. Saha
Publikováno v: Journal of Economic Entomology. 64:50-53
Efficiencies of acetonitrile, acetone, ethanol, and methanol in extracting root-absorbed 14C-dieldrin and 14C-lindane residues from wheat plants were compared. Single extraction with these solvents in a blender recovered 68-82% dieldrin and 75-96% li
