Abstract:
:Residues were analyzed in the fat of yearlings after exposure on pasture to continuous protection from horn flies with spray treatments of DDT. Eleven applications of 2 quarts of a 0.25 per cent suspension per head produced total residues of DDT, TDE and DDE that exceeded the acceptable tolerance of 7 p.p.m. when animals had reached the prime slaughterweight on a high-energy finishing ration. More information is needed on the mobilization of fat and the DDT stored within the depot to relate an acceptable tolerance for slaughter cattle to practical methods in beef production.

杂志文章abstract::Phthalate diesters are used in personal care products, plastics, and pesticides, resulting in widespread human and wildlife exposure. Phthalate diesters leach out of these products and ultimately enter biological systems where they are quickly metabolized to phthalate monoesters and glucuronides. As such, phthalate mo...

abstract::Aroclor 1242 is inhibitory to long-term batch growth of Euglena gracilis at 10 ppm. Exposure to PCB's, subsequent to an initial drop of 50% in the first 30 minutes, does not appear to inhibit photosynthesis on a per cell basis over the time span of four hours. Consequently our experimental findings suggest that inhibi...
