The Sergipe River estuary has been subjected to a range of anthropogenic activities including food, plastic, textile, ceramic and metallurgical production plants along with domestic sewage inputs, all of which are of environmental concern. In this study, the levels of fecal coliforms (FC) in surface water samples and sterols in superficial sediment samples collected from the Sergipe River estuary were determined. Based on the FC concentrations, 58% of the water samples were considered Water Potentially Unusable (WPU) according to the United States Environmental Protection Agency (USEPA). Concentrations of coprostanol ranged from 13 to 1072 ng g, indicating a significant input of sewage at some points in the estuary. Principal Component Analysis (PCA) showed that there is no clear correlation between the coprostanol and coliform data, which may be due to the high resistance to degradation of coprostanol in sediments and to recent inputs of sewage at the water sample collection points.
塞尔希培河口受到了多种人为活动的影响，包括食品、塑料、纺织、陶瓷和冶金生产厂以及生活污水的排放，所有这些都对环境构成了威胁。在这项研究中，测定了塞尔希培河口地表水样本中的粪大肠菌群 (FC) 和表层沉积物样本中的甾醇水平。根据 FC 浓度，根据美国环境保护署 (USEPA) 的标准，58%的水样被认为是潜在不可用水 (WPU)。粪甾烷的浓度范围为 13 至 1072ng/g，表明在河口的某些点有大量污水的输入。主成分分析 (PCA) 表明，粪甾烷和大肠菌群数据之间没有明显的相关性，这可能是由于粪甾烷在沉积物中的抗降解性较高，以及在水样采集点最近有污水的输入。
