متن کاملRelative Toxicity of PCB Congeners to Sea Urchin Embryos
The toxicity of three PCB congeners having different structural characteristics was studied using water exposures and the embryos of two sea urchin species, Strongylocentrotus purpuratus (purple sea urchin) and Lytechinus pictus (white sea urchin). Biological effects were assessed using two endpoints: percentage of normal embryo development and mitotic rate. Differential toxicity of the congene...
متن کاملToxicity of PCB 1232 on mitochondria of fish Arius caelatus (Valenciennes).
Mitochondrial proteins and phospholipids were estimated and SDH, Na(+)-K(+)-ATPase and Mg(2+)-ATPase activities were analysed in the gill, liver and heart tissues of PCB 1232 (sublethal doses) treated fish A. caelatus. Protein and phospholipids were found to be decreased significantly and SDH, Na(+)-K(+)-ATPase, Mg(2+)-ATPase and other enzyme systems displayed an inverse relationship with PCB d...
متن کاملReproductive toxicity of commercial PCB mixtures: LOAELs and NOAELs from animal studies.
This paper reviews the developmental/reproductive toxicity of commercial polychlorinated biphenyl (PCB) mixtures in animals and reports on the "no-observable-adverse-effect levels" (NOAELs) and "lowest-observable-adverse-effect levels" (LOAELs) from these studies. Identification of the lowest effective doses for reproductive toxicity of PCB mixtures is difficult because a variety of reproductiv...
متن کاملToxicity and fetotoxicity of TCDD, TCDF and PCB isomers in rhesus macaques (Macaca mulatta).
In rhesus macaques (Macaca mulatta), consumption of food containing commercial polychlorinated biphenyl (PCB) mixtures, some pure polychlorobiphenyl congeners, 2,3,7,8- tetrachlorodibenzo-p-dioxin (TCDD), and 2,3,7,8-tetrachlorodibenzofuran (TCDF) caused the same clinical toxic manifestations and histopathologic lesions, although the potencies of the toxicants covered a range of five orders of ...
