文摘
Concentrations of sewage markers were determined in surface sediments of a tropical estuary.
Sterols were determined by ultra-high performance liquid chromatography tandem mass spectrometry.
Despite the biogenic sources of sterols, anthropogenic input was predominant.
High concentrations of coprostanol provided evidences of sewage pollution.
