The Parati River contributes to the Babitonga Bay water complex, but the contents of the bay also influence the river during periods of inverted currents. In this study, the water quality along four stretches of the Parati River and Babitonga Bay was evaluated using chemical (physico-chemical and chromatographic analysis), microbiological (fluorescein diacetate hydrolysis) and ecotoxicological (Lumistox) methods to assess the reciprocal influence of the waters of this river-bay system. In addition, the most appropriate type of analysis for the monitoring of the estuarine region of the Parati River was identified. The results of six sampling campaigns showed that the type of contaminants and their levels varied temporally and spatially and thus the water quality also changed. Anthropogenic activity, such as banana cultivation and the release of sewage into the water system, is the primary cause of the contamination that affects the quality of the water in the Parati River estuary, which is a crucial ecological niche for the reproduction of various marine species. The ecotoxicity tests with conducted to evaluate the water quality showed an integrative response, and the ecotoxicity data indicated that the Parati River does not have a significant influence on the water quality of Babitonga Bay.
帕拉蒂河为巴比通加湾水系做出了贡献，但在反向潮流期间，湾内的水也会对河流产生影响。本研究采用化学（理化和色谱分析）、微生物学（荧光素二乙酸酯水解）和生态毒理学（发光细菌）方法对帕拉蒂河和巴比通加湾的四个河段的水质进行了评估，以评估该河湾系统的水之间的相互影响。此外，还确定了监测帕拉蒂河河口区最适合的分析类型。六次采样活动的结果表明，污染物的类型和水平随时间和空间而变化，因此水质也发生了变化。人为活动，如香蕉种植和污水排入水系，是造成污染的主要原因，这影响了帕拉蒂河河口的水质，而该地区是各种海洋物种繁殖的关键生态位。进行发光细菌测试以评估水质，结果显示出综合反应，生态毒性数据表明帕拉蒂河对巴比通加湾的水质没有重大影响。
