城市污水被认为是南美洲最重要的海洋污染源之一，因为大多数沿海城市没有适当的设施来处理和处置污水。帕拉纳瓜河口系统是南美洲海岸的一个重要河口环境，渔业、城市和旅游活动、工业和巴西主要的谷物运输港口是该地区的潜在污染源。沉积有机质的人为输入，代表污水的贡献，粪便类固醇浓度进行了评估。粪甾烷醇水平相对较低（<0.10μgg−1），但帕拉纳瓜市附近的地点除外，那里的粪甾烷醇浓度达到2.22μgg− 1，显示出严重的污水污染。粪便中的类固醇水平与世界各地沿海沉积物中报告的中低浓度水平相当。这项工作的结果表明，污水污染可以被认为是帕拉纳瓜河口一小部分的问题。
Urban sewage is considered one of the most important sources of marine pollution in South America, because most coastal cities do not have proper facilities to treat and dispose of sewage. The Paranaguá estuarine system is an important estuarine environment of the South American coast where fishing, urban and tourist activities, industries and the main Brazilian grain shipping port are potential sources of pollution in this area. The anthropogenic input of sedimentary organic matter, represented by sewage contribution, was evaluated by fecal steroid concentrations. The coprostanol levels were comparatively low (<0.10μgg−1), except at the sites close to Paranaguá city, where the coprostanol concentration reached 2.22μgg−1showing strong sewage contamination. Fecal steroid levels were comparable to the lower to midrange concentrations reported for coastal sediments worldwide. The results of this work demonstrated that sewage pollution can be considered a problem for a small part of the Paranaguá estuary.
