In the present study a mass balance calculation was used to quantify trace elements (Al, Ba, Cd, Cr, Cu, Fe, Mn, Pb, Ti, V and Zn) fluxes exported from the Serinhaém River estuary to the Atlantic Ocean. The studied elements exportation in the particulate fraction showed higher fluxes in the first sampling campaign and a high export rate to the Atlantic Ocean during this period. The physical-chemical parameters showed the highest values in sampling campaign 1. These variations are probably the cause of the different trace elements behavior in fluvial and estuarine areas, where removal and addition processes between particulate and dissolved phases took place, affecting distribution coefficient and fluxes to the Atlantic Ocean. EPA ecosystems present values in accordance with Brazilian legislation for pristine areas, however, monitoring programs must be carried out in the region, to avoid future environmental problems.
在本研究中，采用质量平衡计算来量化从塞里尼亚姆河河口输出到大西洋的微量元素（铝、钡、镉、铬、铜、铁、锰、铅、钛、钒和锌）通量。在第一次采样活动中，所研究元素在颗粒态部分的输出通量较高，且在此期间向大西洋的输出速率也很高。物理化学参数在采样活动1中显示出最高值。这些变化可能是河流和河口区域微量元素行为不同的原因，在这些区域颗粒相和溶解相之间发生了去除和添加过程，影响了分配系数和向大西洋的通量。美国环境保护局（EPA）生态系统呈现出符合巴西原始地区立法的数值，然而，必须在该地区开展监测计划，以避免未来出现环境问题。
