Seminal book in the field of pesticide resistance. The development of resistance to pesticides is generally acknowledged as one of the most serious obstacles to effective pest control today. Since house flies first developed resistance to DDT in 1946, more…
Databases were developed to store and search acquired data from analytical runs. Sophistication and capabilities expanded as the computers developed. In 1982 the first generation of LIMS was introduced in the form of a single centralized minicomputer, which offered the…
Enzyme immunoassays enable field portability and testing at the site of contamination View Source
When Dr. Hammock was elected to the U.S. National Academy of Sciences in 1999, he was cited for his pioneering work in using immunochemistry to analyze and monitor human exposure to environmental chemicals Source: Hammock, B.D. and R.O. Mumma. 1980.…
The technique provides sensitivity and selectivity to assay a wide variety of samples for non-volatile organic compounds including large biomolecules. Tandem quadrupole LC-MS/MS quantifies more pesticides and tests for more drugs-of-abuse than perhaps any other analytical technique. Mass spectrometry was…
The Food and Drug Administration announced today that it would ban the use of saccharin in foods and beverages, because the artificial sweetener had been found to cause malignant bladder tumors in laboratory animals. This ruling led to a significant shift in policy as…
A seminal book in the field of insecticide toxicology. Covers Penetration and Distribution of Insecticides, Microsomal Oxidation and Insecticide Metabolism, Cytochrome P450, Extramicrosomal Metabolism of Insecticides, Enzymatic Conjugation and Insecticide Metabolism View Source
Seminal book in the field of insect toxicology, based on teaching notes from his course on the toxicology of insecticides to provide comprehensive and up-to-date text; covering Principles of Insecticide Toxicology, Classification of Insecticides, Modes of Action of Insecticides and…
GC becomes a standard technique for detection of residues as well as characterization of actives with ever improving detectors of electron capture, flame ionization and nitrogen/phosphorus detection (1970s) to mass spectrometers (1980s). View Source
Solid-phase extraction (SPE) is the most widely used sample preparation technique for assays of aqueous samples and organic extracts in laboratories. SPE provides fast cleanup, reduction in solvent usage and improved selectivity. SPE methods, using bonded silicas or other solid…
