Dissolved trace element concentrations (Ba, Fe, Mn, Si, Sr, and Zn) were investigated in the Haicheng River near to the Liaodong Bay in Northeast China during 2010. Dissolved Ba, Fe, Mn, and Sr showed significant spatial variation, whereas dissolved Fe, Mn, and Zn displayed seasonal variations. Conditions such as water temperature, pH, and dissolved oxygen were found to have an important impact on redox reactions involving dissolved Ba, Fe, and Zn. Dissolved Fe and Mn concentrations were regulated by adsorption or desorption of Fe/Mn oxyhydroxides and the effects of organic carbon complexation on dissolved Ba and Sr were found to be significant. The sources of dissolved trace elements were found to be mainly from domestic sewage, industrial waste, agricultural surface runoff, and natural origin, with estimated seasonal and annual river fluxes established as important inputs of dissolved trace elements from the Haicheng River into the Liaodong Bay or Bohai Sea.
2010 年，对中国东北辽东湾附近海城河流域的痕量元素（钡、铁、锰、硅、锶和锌）溶解浓度进行了调查。溶解的钡、铁、锰和锶呈现出显著的空间变化，而溶解的铁、锰和锌则表现出季节性变化。水温、pH 值和溶解氧等条件被发现对涉及溶解钡、铁和锌的氧化还原反应有重要影响。溶解的铁和锰浓度受到 Fe/Mn 水合氧化物的吸附或解吸的调节，而有机碳对溶解的钡和锶的络合作用被发现具有重要意义。溶解痕量元素的来源主要来自生活污水、工业废水、农业地表径流和自然源，所估算的季节性和年际河流通量是海城河流向辽东湾或渤海输入溶解痕量元素的重要途径。
