The results of our research show that in terms of anthropogenic chemical burden diminution on the human organism between of 1987 �1993, the indexes of still-births as well as up to one year infant mortality have decreased. On the background of almost half-decreasing volume of pollutions in the town the still-births rate decreased from 19.2%o to 10.09%o. Up to 1 year infantile mortality decreased for 8.85%o. Infantile breathing pathologies rate decreased triple. At the same period the death-rate in the group of respiratory pathologies decreased from 28.2 to 24..05 (per 100 000 of population). The decrease of summary pollutions index �P�(1) from 10.7 to 4.8 is correlated with the stillbirth-rate decrease as (r=0.85); correspondingly the breathing pathologies death-rate decrease can be described as the average correlation (r=0.44).
