Abstract
Proton activation analysis (PAA) can be considered as complementary to NAA for the determination of elements of great environmental importance such as Pb, T1, Ti, Ge, V. The method was calibrated for the determination of lead in biological standard reference materials by instrumental analysis (IPAA), obtaining a detection limit of 0.1 ppm, for this type of matrices. Selective radiochemical separations in order to improve the sensitivity of the contemporary determination of Pb, T1, Ge ... are described in some details. A lead determination in pooled serum and red blood cells of 15 unexposed subjects by instrumental and radio-chemical analysis is carried out. © 1982 Akadémiai Kiadó.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
