Dra. Victoria Bermejo
Senior Scientist in the Ecotoxicology of Atmospheric Pollution group at the Centre for Energy, Environmental and Technological Research (CIEMAT). Her main lines of research are the effects of ozone and climate change on Mediterranean crops and ecosystems. His work focuses on characterising the atmospheric deposition of ozone and nitrogen compounds in natural ecosystems and the effects on the growth, physiology and biochemistry of vegetation. His research has an important pre-legislative component as it focuses on the determination of damage thresholds (critical levels and loads) above which pollutants are likely to produce adverse effects on ecosystems, values that are then transposed into air quality policies.
Much of the experimental activity is carried out in an installation of Open Top Chamber (OTCs) managed by GECA, the experimental system is used to determine and quantify the relationship (function) between plant response and pollutant dose.
