Researchers from IMDEA Water presented their work at the 33^rd European meeting of the Society for Environmental Toxicology and Chemistry (SETAC), held in Dublin (Ireland) from April 30^th to May 4^th. The outcomes presented include topics such as the fate and risks of microplastics, nanoplastics and other multiple stress factors in the environment.

The researchers –which belong to the Ecotoxicology and Microbial Contamination, Soil and Water Quality in the Environment and Membrane Technology groups– have presented various studies carried out through the Papillons, µNanoCare, ECORISK2050, CICLIC, nanoClean y Nat4Health projects.

Paula Redondo-Hasselerharm, postdoctoral researcher in the Ecotoxicology group, spoke about the environmental risk of microplastics in agricultural soils. Andreu Rico, principal investigator of the same group, chaired a session on the responses of ecosystems to multiple stress factors in a changing climate. In addition, he gave a talk on the influence of climate change on the distribution of macroinvertebrates in European surface waters and their sensitivity to chemical contamination. They have also presented several posters on the research conducted in the Papillons, CICLIC and ECORISK2050 projects.

Cynthia Rieckhof Rivas, pre-doctoral researcher in the Soil and Water Quality in the Environment group, explained the results of her research on the fate of nanoplastics in soils. Lesly Ayala Cabana, from the same group, spoke about the interaction of pharmaceutical products and trace metals in the water-soil-plant continuum. Pre-doctoral researcher Anamary Pompa Pernía, from the Membrane Technology group, explained her work on the elimination of polystyrene nanoplastics in urban wastewater using aerobic membrane bioreactors.
