Abstract

The information collected on the presence and distribution of petroleum hydrocarbons and PAH's along the mexican coastline of the Gulf of Mexico is presented.

The highest total concentrations of hydrocarbons correspond to Mancha and Salada lagoons in Veracruz, State (5.01ugg-1 for sediments and 4.82ugl-1 for suuperficial water).

On the other hnd the sediments of the continental shelves of Tamaulipas and Veracruz also showed high levels (4.45 and 3.3ugg-1).

Of paramount importance is the presence of PAH's in coastal lagoons because of their ecologicl importance, specially those compounds conformed by 3, 4 and 5 benzene rings because their crcinogenic properties as Benzo(a) pyrene and Crysene.

The composition of the PAH's identified is related with their main sources as pyrolisis, burn of vegettion, oil spill, diagenesis of organic matter, seeps and atmospheric transport.

Thus, the presence of PAH's in coastal ecosystems of the Gulf of Mexico as lagoons, estuaries, riveers and continental shelf is of paramount importance because their carcinogenic propoerties as well as their risks for human health.
