“…Considering sediments without sewage contamination, the IP contents represent approximately 60% of the TP (Mater et al, 2004). In the sediment core, values greater than 60% are observed as far back as 1840 (Fig.…”

“…A phosphorus analysis was carried out based on methods described by Mater et al (2004). For each sample, two subsamples of 0.5 g dried sediment were used for the phosphorus analyses.…”

“…These values are higher than those found in the sediments of Ratones Mangrove (59 to 61%), with no contribution of anthropogenic sources, but similar to those reported for the highly sewage contaminated sediments of Itacorubi Mangrove (79-87%), both located on Santa Catarina Island. 22 From these results it is clear that the OP:IP ratio is affected by sources of phosphorus. According to Marins et al 23 , IP accounts for the major fraction of total phosphorus in the estuary of the Jaguaribe River, in Ceará State, and comprises 60% of TP in sediments without anthropogenic input.…”

“…9,10 These compounds are abundant in plant epicuticular waxes, with a strong predominance of odd chain-lengths (mainly C 29 and C 31 ) for hydrocarbons and even chain-lengths (mainly C 26 and C 28 ) for alkanols. 11 Marine algae and bacteria are minor sources, with carbon chain-lengths up to C 22 . [11][12][13] Apart from being of biogenic origin, saturated hydrocarbons can also be related to petroleum sources, but they show no clear odd/even predominance and a characteristic unresolved complex mixture.…”

“…Most of the studies conducted in Brazilian aquatic systems have focused on the distribution of sterols in estuaries and/or coastal bays, [6][7][8][9] estuarine lagoons 10 and lagoon systems, 11,12 but rarely on exclusively fluvial systems. 13 In this study, it was investigated the regional distribution of steroids in sediments from the Iguaçu River and its tributary, the Barigui River.…”
