Geochemistry: A lead on Lead

Modeling lead input and output in soils using lead isotopic geochemistry.

The aim of this study is to model downward migration of lead from the plow layer of an experimental site located in Versailles (about 15 km southwest of Paris, France). Since 1928, samples have been collected annually from the topsoil of three control plots maintained in bare fallow. Thirty samples from 10 different years were analyzed for their lead and scandium contents and lead isotopic comp...

ICD lead abandonment is without risk? A case of “lead on lead crime”

Introduction Lead failure rates of implantable cardioverter-defibrillators (ICDs) vary depending on design and composition, and can be as high as 40% a few years post implant. The Sprint Fidelis lead (Medtronic, Minneapolis, MN) was recalled in 2007 because it is prone to fracture, particularly to its pacesense conductor, which predisposes patients to inappropriate shocks; its yearly failure ra...
