Pb, Cd, Se, As in blood and urine of children from high and low polluted districts of Saint-Petersburg. The elements concentrations and health of children
At present time rapt attention is attended on child health. One of the main factors of child health is environmental
condition and possibility of toxic elements consuniption by children from air, water, and food. The ain of our investigation is
to detennine Pb, Cd, Se, As in blood and urine of children from high and low level polluted districts of St.-Petersburg. And
then to estimate urine and blood toxic elements concentration correlation. ln order to examine large child groups it is necessary
to use effective, express analycal methods. Wc chose Zeeman Modulation Polarization Atomic Absorption Spectrometry with
High-Frequency Modulation as such a method. New technique Zeeman Modulation Polarization Atomic Absorption
Spectrometry with High-Frequency Modulation allow io determine many etements directly (without additional compounds and
reagents or with there minimum use) in blood, plasma and urine. Highcst spectrometry selectivity allows working with high
background level. The matrix effects are reduced in great deal the aid of L'vov platform, sample pyrolysis and palladium
modifier using. We present the results of our investigation – the concentration of toxic éléments in blood and urine of children
from high–Polluted district is above permitted level
