During studies on the accumulation of heavy metals in animal organs and tissues, only small samples (0.5-2 g) rich in lipids and having low concentrations of metals are often available. This may lead to loss of metals in the various steps of the analytical procedure. A modified procedure of mineralization for the determination of Pb, Cd and Zn is described, as well as suitable analytical procedures used by the Authors for the determination by atomic absorption spectrophotometry. Results showed that the loss of metals is minimized with these procedures.

UI	MeSH Term	Description	Entries
D007202	Indicators and Reagents	Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.
