The measurement was carried out according to Methodical Guidelines 4.1. 3230-14 (FR.1.31.2014.17064) developed by the authors. Urine samples were directly analyzed after 1/10 dilution (V / V) with 1% nitric acid solution. The validity of the results was confirmed by analysis of standard urine samples SERONORMTM urine (Norway). The results were presented as basic statistical indices: minimum and maximum values, arithmetic mean (AM), geometric mean (GM), 5th, 50th, 95th percentiles, and were interpreted in accordance with current international requirements.</italic></p><p><italic><bold>Results.</bold> In the unexposed group of children the arithmetic mean (AM) for vanadium is 0.68 μ/l; chromium - 1.91 μg/l; manganese 0.96 - μg/l; nickel - 1.84 μg/l; copper - 13.28 μg/l; zinc - 270.56 μg/l; arsenic - 18.- 99 μg/l; selenium - 22.55 μg/l; strontium - 239.09 μg/l; cadmium - 0.12 μg/l; thallium - 0.16 μg/l; lead - 0.83 μg/l. The arithmetic mean in the group of children of the industrial territory for vanadium is - 0.72 μg/l; chromium - 2.13 μg/l; manganese - 1.11 μg/l; nickel - 2.76 μg/l; copper - 26.67 μg/l; zinc - 482.1 μg/l; arsenic - 10.09 μg/l; selenium - 32.84 μg/l; strontium - 1275.35 μg/l; cadmium - 0.122 μg/l; thallium - 0.16 μg/l; lead - 2.16 μg/l. Evaluation of the results of the study showed AM excess of nickel, copper, zinc, strontium and lead.</italic></p><p><italic><bold>Conclusion.</bold> The paper presents regional features of the urine elemental composition in children who permanently reside in Western Urals’ rural and industrial areas. The study results based on the 95 percentile (P95) can be used as approximate reference data as a basis for assessing the risk associated with exposure to metals. The comparative evaluation of the obtained results with the reference concentrations used in Europe, the USA and Canada for national human biomonitoring programs was carried out.</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic><bold>Введение.</bold> Элементный состав мочи является актуальным и востребованным показателем в медико-биологических, биомониторинговых исследованиях по оценке степени контаминантной нагрузки биосред и рисков здоровью населения.</italic></p><p><italic><bold>Материал и методы.</bold> Cодержание 12 элементов (V, Cr, Mn, Ni, Сu, Zn, As, Se, Sr, Cd, Tl, Pb) в моче неэкспонированных детей сельского поселения и промышленного региона Западного Урала (n = 100 и n = 57 соответственно, средний возраст &lt; 6 лет) определено методом ИСП-МС на квадрупольном масс-спектрометре с индуктивно-связанной плазмой Agilent 7500cx (Agilent Technologies, USA) с октопольной реакционно/столкновительной ячейкой (ORS). Измерение выполнено в соответствии с разработанной авторами методикой МУК 4.1.3230-14 (ФР.1.31.2014.17064). Образцы мочи напрямую проанализированы после разведения 1/10 (V/V) 1% раствором азотной кислоты.Правильность результатов подтверждена анализом стандартных образцов мочи SERONORMTM urine (Норвегия). Результаты представлены в виде базовых статистических показателей: минимальное и максимальное значение, среднее арифметическое (АM), среднее геометрическое (GM), 5-й, 50-й, 95-й перцентили, и интерпретированы с учётом современных международных требований.</italic></p><p><italic><bold>Результаты.</bold> В неэкспонированной группе детей среднее арифметическое (АM) составляет для ванадия 0,68 мкг/л; </italic><italic>хрома – 1,91 мкг/л; марганца – 0,96 мкг/л; никеля – 1,84 мкг/л; меди – 13,28 мкг/л; цинка – 270,56 мкг/л; мышьяка – 18,99 мкг/л; </italic><italic>селена – 22,55 мкг/л; стронция – 239,09 мкг/л; кадмия – 0,12 мкг/л; таллия – 0,16 мкг/л; свинца – 0,83 мкг/л.</italic><italic>В группе детей промышленной территории среднее арифметическое составляет для ванадия 0,72 мкг/л; хрома – 2,13 мкг/л; марганца – 1,11 мкг/л; никеля – 2,76 мкг/л; меди – 26,67 мкг/л; цинка – 482,1 мкг/л; мышьяка – 10,09 мкг/л; селена – 32,84 мкг/л; стронция – 1275,35 мкг/л; кадмия – 0,122 мкг/л; таллия – 0,16 мкг/л; свинца – 2,16 мкг/л.
