The Negative Impact of the Boron Industry on Waters of the Rudnaya River (Primorsky Krai, Dalnegorsky District)

With a view to considering the boron industry on the waters of the Rudnaya river, the hydrochemical data of samples of river and drainage waters of tailing dumps selected seasonally were analyzed; their temperature, pH value and mineralization were determined. The use of the method of physico-chemical modeling in the Selector program made it possible to make mixing models of the studied waters on the geochemical barrier “natural surface—technogenic waters”, to determine the forms of migration of the main elements of ores and the main flotation reagent (H₂SO₄): Ca, B and S. The article presents the results of a seasonal assessment of the negative impact of the boron industry on the chemical composition of the waters of the Rudnaya River and shows the excess of MPC_fish and MPC_gen for Ca, P, Mn, Zn, B and S.
