Satellite Event - Cyanobacteria and Cyanotoxins in Aquatic Environments
Organized in collaboration with the American Chemical Society and CYANOCOST Action ES 1105.
Co-conveners: Dr. Dionysios Dionysiou, University of Cincinnati, USA; Dr. Triantafyllos Kaloudis, Athens Water Supply and Sewerage Company - EYDAP SA, Greece; Dr. Antonio Quesada, Universidad Autónoma de Madrid, Spain.
Cyanobacteria are well known aquatic organisms that may produce secondary metabolites called generically cyanotoxins. These compounds are of very different chemical nature and present diverse severe effects on humans and other organisms exposed to them. Nowadays, national legislations, regulations and guidelines consider cyanobacteria and cyanotoxins as serious health risks associated to both drinking and recreational waters.
With this workshop we aim to open the field of cyanobacteria and cyanotoxins to the scientific community implicated on Chemistry and the Environment. Many relevant challenges on cyanotoxins research are appearing last years implicating multi- and transdisciplinary research and industry. In this symposium we will discuss the latest information available on 4 different topics: i) Ecology; ii) Health; iii) Detection and iv) Treatment.
