Itajai-Acu河口区是巴西南部最重要的河口系统之一，因为Itajai港是巴西国际贸易的主要通道，也是巴西最大的国家鱼杆登陆点。此外，工业以及城市和旅游活动是这一地区的潜在污染源。本研究采集了沿着河口水系12个站位的沉积物样品，采用超高效液相色谱-串联质谱（UHPLC-MS/MS）进行分析。八甾醇被确定和量化，表明自然和人为来源。粪甾烷醇浓度范围为
The Itajai-Acu estuarine region is one of the most important estuarine systems of south Brazil, due to the location of the Itajai Harbor, which is the major route of international trading of the state and the largest national fishing pole landing. In addition, industries as well as urban and tourism activities are potential sources of pollution in this area. In the present study, sediment samples from 12 stations along the estuarine system were collected and extracted followed by ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) analysis. Eight sterols were identified and quantified, indicating natural and anthropogenic sources. Coprostanol concentrations ranged from
