Sediments from Admiralty Bay, Antarctica were collected during the austral summers of 2002/2003 and 2003/2004 in order to assess the distribution and concentration of sewage indicators originating from Comandante Ferraz Brazilian Antarctic Station. Fecal sterols (coprostanol+epicoprostanol) and linear alkylbenzenes (LABs) ranged from <0.01 to 0.95 microg g(-1) and <1.0 to 23 ng g(-1) dry weight, respectively. In general, the higher concentrations were found only locally in the vicinity of Ferraz station at Martel Inlet. Baseline values for fecal sterols and coprostanone were calculated as 0.19 and 0.40 microg g(-1), respectively. According to fecal sterols concentrations, sewage contribution to Martel Inlet has increased more than twice since 1997, as result of the increase in the number of researchers at the station especially during the last decade. A low correlation was found between total LABs and fecal steroids, which could be attributed to the contribution of the natural sources of steroids.
2002/2003 年和 2003/2004 年南极夏季期间，在阿德默勒尔蒂湾采集了沉积物，以评估源自巴西费拉兹南极站的污水指示物的分布和浓度。粪甾醇（粪甾醇+粪胆甾醇）和直链烷基苯（LABs）的范围分别为<0.01 至 0.95 微克/克（干重）和<1.0 至 23 纳克/克（干重）。通常，仅在费拉兹站附近的马特尔湾附近局部地区发现浓度较高。粪甾醇和粪胆甾酮的基线值分别计算为 0.19 和 0.40 微克/克。根据粪甾醇浓度，自 1997 年以来，由于站内研究人员数量的增加，特别是在过去十年中，马特尔湾的污水贡献增加了两倍以上。总 LABs 和粪甾醇之间的相关性较低，这可能归因于甾体的天然来源的贡献。
