This research group belongs to the IIMyC-CONICET institute and the Marine Science Department, UNMdP. It was created in 2018 to give new insights into the dynamics of pollutants in a globally changing environment. We aim to study the interaction among natural stressors and those of anthropogenic origin, mainly on aquatic ecosystems. Additionally, we propose the development and use of cost-effective tools to assess adverse effects in biota and for remediation process including those interactions. In this sense, we focus on the knowledge of the fate and dynamics of historical and emerging pollutants in areas under natural stressor´s influence (i.e., salinity, temperature, UVR) at different spatio-temporal scales. Currently, our team is conformed by a multidisciplinary group from the ecotoxicology, physiology, and environmental chemistry areas, leading to a holistic view necessary for environmental sciences training. Additionally to the IIMyC, our research group have members from other research institutions (Dr. Cesar Pegoraro, CONICET, Departamento de Química y Bioquímica, FCEyN-UNMdP; Dra. Francesca Mitton, CONICET-INIDEP). Additionally, we also work in collaboration with colleagues from national universities, research institutes, and industries. In terms of international partnership, we note participation in international networks and collaborative works with researchers from Brazil, Canada, Chile, Spain, Portugal, and the Czech Republic, among others.

Our team focuses on assessing classic/emerging pollutants levels from transitional environments and the joint effects of natural stressors on pollutants availability/effects to key species. We developed the following topics:

1. Occurrence and availability of pollutants ( influence of physico-chemical variables on the adsorption/desorption, degradation/transformation processes, and bioaccumulation)
2. Biota responses to environmental changes (salinity, temperature, and nutrient availability/changes) and its interaction (tolerance, sensibility) with anthropogenic stressors (pollutants).
3. The influence of environmental variables and pollutants mixtures on watershed pollution management and remediation processes.

We are currently running several projects dealing with pollutants dynamics in sediments from the southwestern Atlantic coast of the Buenos Aires province (Pampa and Patagonia biome). Additionally, we are running the first laboratory and field studies about the interaction between natural and anthropogenic stressors on key representative species from Argentinean coastal/aquatic environments,
