Environmental Chemistry and Recovery

Principal Investigator:
Marisa Almeida

The team research interests are focused in the environmental chemistry of coastal and estuarine environments, monitoring different contaminants, namely metals, hydrocarbons and emerging pollutants (e.g., pharmaceuticals, endocrine disrupting compounds and microplastics) in different environmental matrixes (water, sediment and biota) and studying the different biogeochemical processes of contaminants in water and soil compartments. The team also has a strong focus on the research of the potential of natural and constructed wetlands for the remediation of media contaminated with different pollutants and well as in exploring phytoremediation processes for environmental cleaning/recovery through nature-based solutions. By monitoring the reduction of the chemical contaminants levels due to the application of these tools and investigating contaminants processes leading to that removal, the research team generates essential knowledge to promote the use of these biotechnological tools for the removal of persistent and emergent pollutants. By collaborating also with teams of different expertises, such as those in microbial, ecological and toxicological fields, one of the team’s research interests is also to contribute for an holistic and interdisciplinary view of coastal and estuarine environments where physical, chemical and biological processes occur simultaneous and interconnected. The team also participates actively in science dissemination activities, regularly giving talks to the general public and school students in the frame of CIIMAR outreach programs and projects, regarding both ocean and water literacy.
