Soil microbial degradation of Aldrin
Life Sciences, 1968Abstract The degradation of aldrin by soil microorganisms has been investigated. Ninety-two pure cultures were screened in vitro for aldrin degrading activity. The majority showed some capacity for converting aldrin to dieldrin. Among the fungi, Trichoderma were the most active, followed by Fusarium and Penicillium ...

The Effects of Aldrin on Birds
The Journal of Wildlife Management, 1952The Bureau of Entomology and Plant Quarantine, United States Department of Agriculture and the Wyoming Department of Agriculture carried out a grasshopper control program on approximately 300,000 acres of Wyoming range land during the summer of 1951. Aldrin (Compound 118) was used as the toxicant.

Chlordane, Aldrin and Dieldrin
1969Chlordane, Aldrin and Dieldrin, three powerful new insecticides, were discovered in the middle forties and in each case Julius Hyman was intimately involved in the discovery. Hyman held degrees from the Universities of Chicago and Leipzig. In 1930 he gave up a post as research chemist in order to develop his own ideas for the manufacture of drying oils

Solar photocatalytic degradation of Aldrin
Catalysis Today, 2002Abstract Photocatalytic degradation of the pesticide Aldrin dissolved in water was carried out, in one case, using concentrated solar radiation and, in another case, using non-concentrated solar radiation. In these experiments, the effects of catalyst concentration, oxidant agent concentration, and solar irradiation were tested.

Pesticide Biochemistry and Physiology, 1990
Abstract The mechanisms responsible for 300-fold higher levels of aldrin resistance in western corn rootworms relative to the closely related and sympatric northern corn rootworm were investigated. In vivo metabolism of [14C]aldrin by the resistant and susceptible rootworms proceeds similarly with a rapid conversion to its epoxide, dieldrin, which ...

Selective binding of aldrin and dieldrin in cartilage
Archives of Toxicology, 1980Whole body autoradiography of 14C-aldrin and 14C-dieldrin in pregnant mice indicated a slow but persistent uptake of both substances in cartilage, e.g. in the vertebral and epiphyseal discs. Also in the fetal skeleton a marked accumulation was observed.

The Conversion of Aldrin to Dieldrin on Plants1
Journal of Economic Entomology, 1958The conversion of aldrin to the more residual and equally toxic material, dieldrin, has been found to occur On alfalfa, soybeans, and corn and may take place on plants in general. A 1-pound per acre treatment of aldrin on alfalfa yielded aldrin residues which had dissipated to 0.1 p.p.m. in 8 days after spraying while the dieldrin produced took 25 days

Toxicology and No-Effect levels of aldrin and dieldrin
Toxicology and Applied Pharmacology, 1967Some of the critical values have been selected from the various criteria just reviewed and are listed below. Acute oral toxicity. Twenty to 70 mg/kg, aldrin or dieldrin, 12 species. The estimated lethal dose for man is approximately 5 g. Mortality on repeated doses. (a) Short-term: quail, dog, turkey, mouse,

Vapor-phase photodecomposition of aldrin and dieldrin
Archives of Environmental Contamination and Toxicology, 1974A special reactor was constructed to study the vapor-phase photodecomposition of pesticides by ultraviolet (UV) light. The reactor was designed in such a way that wall reactions would be minimized and could be distinguished from actual vaporphase transformations.

Aldrin and Dieldrin in Human Blood Components
Archives of Environmental Health: An International Journal, 1971Blood samples from six aldrin formulators were separated into erythrocytes and plasma, α- and β-lipoprotein fractions. Each blood component was analyzed for aldrin and dieldrin residues, with the latter being in greater concentration in all components examined.
