title: [Control of heavy metal (Cu, Pb, Zn) levels in human plasma].
abstract: A new method for wet ashing of biological objects (plasma) with a mixture of concentrated perchloric and nitric acids is proposed. Optimal conditions for measuring heavy metals in human plasma with simultaneous inverse voltammeter were determined. The concentrations of copper, lead, and zinc were measured in the plasma of cardiovascular patients by a solvent photometric, inverse voltammeter, and atomic absorption methods (Cu), by oscillographic, atomic absorption, and inverse voltammeter methods (Pb), and by atomic absorption and inverse voltammeter methods (Zn).
