Pascual, Juan Antonio Blasco, Cristina Picó, Yolanda Poster presentado en el 2nd SCARCE Annual Conference celebrado en Madrid el 28 y 29 de noviembre de 2011 The UNEP-World Conservation Monitoring Centre has estimated that wetlands cover approximately 570 M hectares - roughly 6% of the Earth's land surface. They are among the richest ecosystems in the world. In the Mediterranean, they support high concentrations of birds, mammals, reptiles, amphibians, fish and invertebrate species, many of which are endemic to the region. Furthermore, they are fundamental in the maintenance of the water cycle, purifying and recycling it, at the same time that capture and retain it from the rain. They also act controlling floods and flows, recharging aquifers, etc. In the Valencian Community, the Pego-Oliva Marsh is one of the most important Mediterranean coastal wetland. But despite of its richness, it has to cope with an intense human pressure [1]. Pharmaceuticals come from human excretions, waste eluents of manufacturing processes and animal farms mainly. They can reach environment because the large quantities of production and consumption. This fact, together with some of them have a not high degradation into wastewater treatment processes makes than some of them were disseminating in water environments. A previously method developed in our laboratory [2] was put into practice to monitor the occurrence of a representative set of pharmaceuticals in the Pego-O liva marsh. In 11th June 2009 a total of 31 samples of soil (at two different depths) and sediment were collected, corresponding to different sampling points previously designed. Briefly, samples were concentrated by PLE using water at 90°C as solvent. Then, aqueous extract was pass through an Oasis HLB cartridge and extracted with methanol as solvent. Quantification was carried out by LC-MSIMS with an ESI interface working in both positive and negative mode. Except for ibuprofen, two transitions were utilized for each compound to obtain an unequivocal confirmation. Acetaminophen (paracetamol) and carbamazepine were the pharmaceuticals more frequently found in sediment samples, in concentrations between detection limit and 15 ng/g for acetaminophen and from 0.51 to 1.7 ng/g for carbamazepine. In soils, acetaminophen and ofloxacin were commonly detected in concentrations until maximum of 3.5 ng/g and 3.7 ng/g respectively. Ibuprofen, diclofenac, clofibric acid and oxytetracycline were not detected in any sample. This results demonstrates the incidence of these pollutants in the protected area of Pego-Oliva marsh.
