Переведите на английский, люди добрые!!!В работе исследован химический состав воды рек в зимний период 2009 года с целью оценки качества воды.
Выявлены значения концентраций минеральных и органических веществ, преобладающими ионами во всех водах являются НСО3 и Са
За счет антропогенного фактора возрастает содержание нитритных и аммонийных ионов, наблюдалось свежее загрязнение по течению рек.

We studied the chemical composition of water in rivers in the winter of 2009 with a view to assessing the quality of water. Revealed the concentrations of mineral and organic substances, the predominant ions in all waters are HCO3 and Ca Due to the anthropogenic factor increasing the content of nitrite and ammonium ions was observed fresh pollution along the rivers.

нет проблем! ! In work the chemical compound of water of the rivers during the winter period of 2009 for the purpose of an estimation of quality of water is investigated. Values of concentration of the mineral and organic substances are revealed, prevailing ions in all waters are НСО3 and Sa At the expense of the anthropogenous factor the maintenance нитритных and аммонийных ions increases, fresh pollution on a current of the rivers was observed.
