Anodic stripping voltammetry compared with graphite furnace atomic absorption spectrophotometry for blood lead analysis.
According to a recent CDC report, blood lead concentrations in 1 000 000 US children are at values associated with irreversible damage to health (1 ). The effects of chronic lead poisoning on the developing nervous systems have been well documented (2 ), with children in inner city neighborhoods, where older housing stocks have deteriorating lead paint, most vulnerable (3 ). Accurate screening ...
متن کاملRapid micromethod for blood lead analysis by anodic stripping voltammetry.
We describe a rapid microscale procedure for blood lead determination by anodic stripping voltammetry. Results correlate well with those obtained by atomic absorption spectroscopy. The procedure involves use of a metal-exchange reagent, which rapidly releases bound lead from its macromolecular binding sites, thus eliminating a long and cumbersome perchloric acid digestion procedure. Reproducibi...
متن کاملSimultaneous determination of lead, cadmium, copper and zinc in Infant formula by anodic stripping voltammetry
Determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. Long-term exposure to low levels of toxic metals could be important, especially in relation to children. Differential Pulse Anodic Stripping Voltammetry (DPASV) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...
متن کاملAnodic stripping voltammetry procedure modified for improved accuracy of blood lead analysis.
In evaluating the accuracy and reliability of blood lead (PbB) measurements with the Environmental Science Associates Model 3010A Trace Metal Analyzer, intralaboratory comparison demonstrated that use of the operating conditions recommended by the manufacturer resulted in consistently underestimated PbB concentrations less than 400 micrograms/L and overestimated PbB values greater than 400 micr...
متن کاملHeavy Metal Analysis by Anodic Stripping Voltammetry
Let’s say that you wanted to determine the heavy metal identities and concentrations in sediment and suspended solid samples obtained from present day Lake Nakuru. What technique would you use for this determination? You could use Atomic Absorption Spectroscopy (AAS) as was done in the article (Nelson 1998), but another technique, which is particularly good at detecting metals at the ppb level ...
