1. Metabolism of some polychlorinated biphenyl and polybrominated diphenyl ether congeners in the rat
Abstract : For the understanding of the metabolic fate of xenobiotics, in vivo studies are needed. In this thesis the metabolism of CB-28 and CB-77 and BDE-209 in the rat are determined. In addition, pharmacokinetic studies of CB-28 and BDE- 209 are included. The compounds were radiolabelled and their excretion and tissue distribution determined. READ MORE

Narrating Nuclear Disaster intervenes in these debates by asking what might be learned about nuclear disasters through an analysis of the formal and affective strategies employed in literary texts narrating their aftermath.
