    <p>В статье рассматриваются проблемы качества воды трансграничных поверхностных вод на примере реки Тобол. Оценку качества водных ресурсов по гидрохимическим показателям проводили в соответствии с общепринятыми нормативами ПДК вредных веществ для воды рыбохозяйственных водоемов. Исследованием установлено превышение нормативов азота аммонийного 1,3 - 3,03 ПДК; нитритов 2,8 - 26,4 ПДК; железа общего 6,2 - 17,3 ПДК; меди 4,31 - 9,55 ПДК; цинка 1,7 - 10,8 ПДК; фенолов 7 - 10 ПДК; нефтепродуктов 2,6 - 26,8 ПДК; содержание органических веществ (по БПК5) составляло 1,22 - 4,29 мг/л при ПДК 2 мг/л. Согласно комплексной экологической классификации качества поверхностных вод суши по О.П. Оксиюк и В.Н. Жукинскому степень загрязнения водных ресурсов соответствует классу от «загрязненной» до «чрезвычайно грязной».</p>
