IOPAN

Your research area:
My scientific interest is focused on the biogeochemical cycle of contaminants in the marine environment. During my PhD, I concentrated on the concentration of pharmaceutical residues in Baltic Sea sediments and their impact on microorganisms. In recent years, I have worked on projects related to the environmental impact of conventional and chemical ammunition dumped after WWII. I was responsible for trace element analysis, including mercury and methylmercury, in various matrices.

Why is your research important?
Understanding the biogeochemical cycle of contaminants helps assess the condition of marine ecosystems. Investigating organic contaminants (e.g., PCBs, PAHs, pharmaceuticals) and inorganic contaminants (e.g., heavy metals) is important because they are potentially dangerous for both marine life and human health.

What are your personal motivations?
I am driven by the knowledge that my research can contribute to a better understanding of the processes occurring in the marine environment, as well as safeguarding ecosystem and human health by investigating harmful pollutants.

What are you going to do during the cruise onboard?
I will be responsible for taking and preparing samples for chemical analyses (eg. mercury, pharmaceutical residues, isotopes, nutrients, alkalinity)
