Fecal sterols as sewage contamination indicators in Brazilian mangroves.

Recent sewage contamination in Brazilian mangrove forests was evaluated using fecal sterols as biomarkers and socioeconomic indicators. The sterols were quantified by gas chromatography/mass spectrometry (GC/MS). Total fecal sterol concentrations ranged between 2.

Assessment of brazilian mangroves hydrocarbon contamination from a latitudinal perspective.

The present study investigated the contamination of Brazilian mangroves sediments by aliphatic hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (PAHs). Samples were obtained from mangroves located along the brazilian coast, between the northern coast and the austral limit of the occurrence of this ecosystem. Total AH ranged from 1.
