Abstract

Iron contamination of drinking water in municipal water supply systems is recognized as a risk factor for impairment of public health. Tap water in the city of Vladivostok has increased iron content (more 0.8 mg /l). The aim of this study was the medical assessment of the actual average daily dose (AADD) of iron consumed by Vladivostok residents with all sources its per oral administration. Present study was performed in February 2017. A random sample of 183 adolescents from 14 to 17 years old from Vladivostok municipal schools was investigated. Daily consumption of tap water, 85 trade names of bottled water, 21 groups of food products and dishes were studied by questionnaire method. The iron content in foods and drinking waters was taken according to the national reference tables and laboratory data. It was established that the iron AADD values among adolescent population were equal about 17 mg/day, what is harmless to the health. At the same time the frequency of iron intake deficiency was 18.37 (boys) and 64.58 (girls) cases per 100 people. It has been found that, against the background of an excessive of the iron content in tap water (up to 2.7 MAC) according to organoleptic limiting sign of harmfulness, the occurrence of deficit of its consumption in boys and girls is due to low consumption levels of foods with the highly bioavailable iron: eggs, animal meat and poultry meat.

Highlights

  • Iron is an essential chemical element for humans [1, 2]

  • The average daily dose (AADD) values of iron intake by the adolescent population are given in table 1

  • Identified values of AADD of oral iron intake cannot be considered harmful to the health of adolescents, since they make up only 127.6% and 84% of the recommended value of consumption in Russia [15] and do not exceed the value of "tolerable upper intake level" for oral consuming in adolescence - 45 mg/day adopted by the World Health Organization [3]

Summary

Introduction

Iron is an essential chemical element for humans [1, 2]. excessive iron intake can have an adverse effect on the body and cause the occurrence of diseases. [3]. The contamination of drinking water with iron is the main cause of numerous complaints and lawsuits of the region population to the owners of drinking water supply systems. Against this background, it is necessary to recognize as paradoxical the fact of the presence of chronic iron deficiency in the body of children, revealed during the in-depth medical examination of organized children's groups in Primorsky Territory [7].
