Abstract Admiralty Bay on the King George Island hosts Brazilian, Polish and Peruvian research stations as well American Ecuadorian field stations. Human activities in this region require use of fossil fuels an energy source, thereby placing at risk hydrocarbon contamination. Hydrocarbon monitoring was conducted water sediment samples from bay over 15 years. Fluorescence spectroscopy used for analysis total polycyclic aromatic hydrocarbons (PAHs) seawater gas chromatography with flame...
A fast, sensitive, and selective ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC–MS/MS) method that is able to quantify geochemical biomarkers in sediment described. pool of 10 sterols, which can be used as autochthonous (cholesterol, cholestanol, brassicasterol, ergosterol), allochthonous (stigmasterol, β-sitosterol, campesterol, stigmastanol) anthropogenic (coprostanol epicoprostanol) organic matter (OM), three triterpenols (lupeol, α-amyrin, β-amyrin) were...
ESTUARY (ITAPICURU -BA RIVER ESTUARY).Estuaries are major areas of organic matter (OM) deposition, playing an important role in the global carbon cycle.The Itapicuru's river estuary (IRE) is North Coast Bahia (Brazil), Environmental Protected Area.Although it presents preserved conditions, some environmental changes caused by human activities can be observed.This study evaluated anthropogenic impacts importance concentrations/sources OM deposited IRE.n-Alkanes and stable isotopes (δ 13 C δ...
