Reversed - phase partithn thin - layer chromatography of rat liver
A PREVIOUS COMMUNICATION described the separation of rat liver lecithin into four main fractions by TLC on silica gel plates impregnated with silver nitrate (1). GLC analysis revealed that approximately 50% of the fatty acids in each of the four fractions, here designated as A, B, C, and D, was made up of two saturated fatty acids, viz., palmitic and stearic. In fraction A the remaining 50% con...

nical mixtures found in the formulation and the measurements made on the basis of calibration with these mixtures. Chlorobiphenyl (CB) refers to the individual congener named by the Ballschmiter number. TEQs refer to the sum of the concentration of the congener equivalent to 2, 3, 7, 8 TCDD obtained by using the toxic equivalence factor for each PCB. POLYCHLORINATED BIPHENYLS: GAS CHROMATOGRAPHY
متن کاملLevels of organochlorine pesticides and polychlorinated biphenyls
Accumulation of organochlorine compounds is well studied in aquatic food chains whereas little information is available from terrestrial food chains. This study presents data of organochlorine levels in tissue and plasma samples of 15 critically endangered Iberian lynx (Lynx pardinus) and other 55 wild carnivores belonging to five species from three natural areas of Spain (Doñana National Park,...
متن کاملDiabetes in Relation to Serum Levels of Polychlorinated Biphenyls and Chlorinated Pesticides in Adult Native Americans
BACKGROUND Recent research suggests that diabetes, a condition whose incidence is increasing, is associated with exposure to polychlorinated biphenyls (PCBs) and chlorinated pesticides. OBJECTIVES We investigated the potential association between diabetes and serum levels of PCBs, dichlorodiphenyldichloroethylene (DDE), hexachlorobenzene (HCB), and mirex in a cross-sectional study of an adult...
متن کاملPolychlorinated biphenyls and chlorinated pesticides in harbor seals (Phoca vitulina concolor) from the northwestern Atlantic coast.
Concentrations of polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and its metabolites, chlordane-related compounds (CHLs), mirex, hexachlorocyclohexane isomers (HCHs), dieldrin, and hexachlorobenzene (HCB) were determined in blubber of harbor seals (Phoca vitulina concolor) from the northwestern Atlantic coast. PCBs, DDTs, and CHLs were the major persistent organochlorin...
