(Table 2) pH and concentrations of dissolved and particulate chemical elements in the mixing zone of the Yur'eva River water and the Okhotsk Sea water

Data on behavior of iron, manganese, nickel, copper, and zinc in the zone where acidic volcanic waters of the Yur'eva River (Paramushir Island, Kuril Islands) mix with sea water are presented. Distributions of dissolved and particulate forms of these elements indicate that the mixing zone acts as a pH-based geochemical barrier, at which almost all dissolved iron and smaller amounts of other metals are precipitated. When chemogenic particulate matter formed in the mixing zone enters the open ocean, it can sorb trace elements from sea water.

本文呈现了千岛群岛幌筵岛尤尔耶夫河酸性火山河水与海水混合带内，铁、锰、镍、铜及锌的地球化学行为数据。上述元素的溶解态与颗粒态分布特征表明，该混合带可作为基于pH值的地球化学障，几乎所有溶解态铁以及少量其他金属均在此处发生沉淀。当混合带内形成的化学成因颗粒物进入开阔大洋后，可从海水中吸附微量金属元素。
