Resumen
The main objectives for the research Project in Doñana are mentioned below:
- to obtain clean sediment samples for their posteriori characterization in Utrech University (OC, clay content, granulometry, etc). Sediment core samples will be used to perform experimental lab work and get insights into the key sediment characteristics and other conditions that affect the bioavailability of surfactants to marine benthic organisms. Fieldwork will cover a carefully selection of the sediments in order to include sediments with a wide range of properties.
- To compare surfactant concentrations from sites in the estuarine zone of the Guadalquivir River receiving properly treated effluents from urban areas with the corresponding values from the laboratory studies that have been performed previously. Any differences between the ranges of bioavailability of the surfactants in sediment collected in the field or spiked in the laboratory should be identified for the different surfactant types. If significant differences are obtained, the parameter (s) to be modified in the laboratory should be assessed to better mimic field conditions.
