This study addressed the identification and monitoring of pollution sources of terrestrial origin in rivers (domestic sewage and industrial effluents) and critical fluvial segments in highly polluted environments under tidal influence (mixing marine and continental sources) from Guanabara Bay Basin, Rio de Janeiro, Brazil. The mass balance of contaminants was determined in conditions of continuous flow (low tide) during dry season (lower dilution capability). The results allowed the evaluation of the potential of contaminant mass generation by the different river segments and the estimation of their natural and anthropogenic components. The water quality of Iguaçú and Sarapuí Rivers were evaluated for metals and biochemical oxygen demand. The method gave an excellent response, including the possibility of sources identification and contaminated river segments ranking. The approach also offers fast execution and data interpretation, being highly efficient.
本研究旨在确定和监测巴西里约热内卢瓜纳巴拉湾流域河流（生活污水和工业废水）和受潮汐影响的高污染环境下关键河流水段（混合海洋和大陆源）的陆地污染源。在持续流动（低潮）条件下进行污染物的质量平衡测定，在旱季（稀释能力较低）。结果允许评估不同河流段产生污染物质量的潜力，并估计其自然和人为组成部分。对伊瓜苏河和萨拉皮尤河的水质进行了金属和生化需氧量评估。该方法反应良好，包括识别污染源和对污染河段进行排序的可能性。该方法还具有执行速度快和数据解释高效的特点。
