Hair elements’ analysis is the perfect tool for clinical screening and diagnostics, used for detection of critically important microelements and macro-elements contained in a human body as well as for definition of ratio of vitally important elements and detection of toxic ones. At that, if the results of blood and urine analysis show a current or recent body’s state, having general nature, the results of hair analysis reflect more long-term period of life.
A number of chemical elements, being detected in hair and having vital importance, can’t be define a using blood and urine analysis or more complex equipment need to be used for their detection. Hair samples have advantages in comparison with other bio substrates, namely: their sample collection is simple, painless, and suitable for further investigation.
Investigation results of its microelement composition are evaluated by comparing with physiological acceptable and critical levels. The methodology developed for the qualitative detection of 30 macro and microelements in human hair is based on the laser atomic emission spectroscopy utilized in elemental analyzer LEA-S500 (manufactured by SOL Instruments Ltd., city of Minsk, Belarus). The methodology allows to reveal ongoing time-dependent dynamics of accumulation of essential and toxic elements on a hair lock for a short time line.
The possibility to perform investigations in dynamics allows to reveal hidden deficit of elements, to avoid clinical phase of this deficit and raise the level of human body functional reserve. Suggested methodology can be successfully implemented for hygienic evaluation of chemical elements balance in bio system based on studying regional micro element passport of population.
