Nowadays, environmental pollution has become a global, stable and constant hazard, in some regions consistent totality of pollutants determine toxic situation. In recent years, much attention in Kazakhstan is paid to Aral region. Despite multiple studies, problem connected with chemical influence on public health in Kazakhstan, Aral region, remains unsolved.

It was determined that a combined deficit of microelements is accompanied by a distribution of copper content between different tissues (increase in red blood cell mass and cerebrum, decrease in myocardium), essential changes of indexes of hypotalamo-hypophysis-thyroid axis, oxygen-dependent metabolism, antiradical defense, exacerbating the effects of negative influence of each of them on organism. It was established that HTGI+Cu causes a suppression of oxygen-dependent processes.

Left ventricular myocardium of victims of accidents without cardiovascular pathology was studied as control. Compared with control dysbalance of various degree was noted in left ventricular myocardium of patients with ischemic heart disease.

The effect of enterosorbents of natural origin, zoosterol and sodium alginate, on the main types of metabolism and the macro- and microelement composition (calcium, magnesium, zinc, copper) of the renal tissues was studied in animals with experimental nephrocalcinosis. Increased complex-forming ability of zoosterol, related to a higher absorption activity of low-molecular-weight fragments of this enterosorbent, favors retention of large molecules in the form of calcium salts in the parenchyma. Sodium alginate favors the elimination of calcium compounds and compensates for calcification of the renal tissue, which allows this this enterosorbent to be used as a crystal-inhibiting complex-forming agent for correcting metabolic dysbalance in cases of nephrocalcinosis.
