Biodegradation of hexadecane using sediments from rivers and lagoons of the Southern Gulf of Mexico

Autor: Juan Sánchez-Avila, Leopoldina Aguirre-Macedo, Gerardo Gold-Bouchot, David Valdés-Lozano, N. Ulises García-Cruz

Publikováno v: Marine Pollution Bulletin. 128:202-207

The Southern Gulf of Mexico is an area highly impacted by crude oil extraction, refining activities and the presence of natural petroleum seepage. Oceanic currents in the Gulf of Mexico continually facilitate the transport of hydrocarbons to lagoons

Simultaneous Determination of Polycyclic Aromatic Hydrocarbons, Alkylphenols, Phthalate Esters and Polychlorinated Biphenyls in Environmental Waters Based on Headspace-Solid Phase Microextraction Followed by Gas Chromatography - Tandem Mass Spectrometry

Autor: Thomas Kretzschmar, Juan Sánchez-Avila

Publikováno v: Journal of Environmental Analytical Chemistry.

In the present work, a sensitive, simple, and fast method with little sample handling has been developed for the determination of 34 semi-volatile organic xenobiotics from rain, sea and ground waters. The method is based on Headspace-Solid Phase Micr
