Abstract
For the first time the physical development of children living in non-ferrous metallurgy enterprises (zinc, lead and titanium-magnesium simultaneously) and in urban areas without similar emission sources were compared, where development indexes and indices were evaluated.Research. To assess the physical development of children living in the sanitary protection zones of the Northern and Northeastern industrial zones.Methods. In the article the physical development of children living on the territory of sanitary protective zones of Northern and North-Eastern industrial centers of Ust-Kamenogorsk city is estimated. When comparing with the clean control areas it was found that the children of primary and secondary school age are characterized by accelerated growth rate, low body weight and weak type of body build.Results. Compared to the control and clean territories, the body mass deficit in the younger age is up to 83.0%, in the high school age - up to 71.2%. "Very weak" type of body build prevails in elementary school students living in the areas of JSC "Uskemen Titanium-Magnesium Plant" (63,0%), JSC "Kazmyrish" and JSC "Ulba Metallurgical Plant" (62,0%).Conclusions. Children living in the studied areas are characterized by an acceleration of the growth rate of body length compared with the control area. The estimation according to centile tables showed that children are characterized by a higher level of body weight in comparison with the control area.Keywords: sanitary protection zone, physical development, schoolchildren, environmental load.
