Abstract: In 2016, Brazil emitted 18.25 Tg of methane. Some of these emissions occur through continental aquatic ecosystems, locations of fate and accumulation of organic and inorganic matter. Thus, the aim of this study is to evaluate the origin of organic matter in Rodrigo de Freitas Lagoon, an eutrophic, coastal and chocked lagoon in Rio de Janeiro, Brazil, through the determination of n-alkanes and sterols compounds in the upper two centimeters of sediment and compare these data with methane ebullitive flux. The con… Show more

“…Biological oxidation of ammonia to nitrite and its subsequent oxidation to nitrate via nitrification or reduction of nitrite and ammonia to N 2 via anammox are known chemolithotrophic processes, but they do not seem to be very relevant in tropical coastal lagoons (Enrich-Prast et al, 2016). Evidence of methane in the water column at high concentrations near the bottom was reported in RFL (Viana et al, 2019), a fact that suggests the availability of substrate occurrence of methane oxidation. Methane oxidation represents an important benthic-pelagic carbon and energy link in lakes, with methanotrophic bacteria being the main actors (Bastviken et al, 2003), and has been reported to be important in tropical aquatic food webs (Sanseverino et al, 2012).…”

“…and sewage (coprostanol), which are considered biomarkers for the presence of animal feces and sewage contamination (Viana et al, 2019). Specifically for station 4, the combination of pluvial and fluvial waters with effluents input resulted in high rates of HBP, extremely high concentrations of total and fecal coliforms and Enterococcus (sometimes 50 times higher than other stations, van Weerelt et al, 2012), associated with high ammonia emissions (Barroso-Santos et al 2012), as well as relatively higher nutrients and lower salinity, pH and oxygen (e.g.…”
