Abstract

In this study the concentrations of 15 saturated hydrocarbons (SH) were determined, both from surface sediments and sediment core samples in Sontecomapan Lagoon, Veracruz, which were analyzed by gas chromatography using capillary columns and flame ionization detection (GC-FID). Total concentrations of SH in surface sediments were in an interval of 0.21 to 12.75 µgg-1 and in cores of 1.33 to 32.01 µgg-1; even carbon chains predominant in almost all samples. In surface sediments outstand the n-alkanes C20, C23, C22, C18 and C21, whereas the higher concentrations in the cores were for C30, C32, C21, C28, C20, C25, C23; basically with a preponderance of even carbons, which demonstrates biogenic origin and anthropogenic for SH, this differs with other studies carried out in lagoons of the Gulf of Mexico, in which is exclusively reported the presence of biogenic hydrocarbons
