[Lecture] Current Status and Challenges of Research on New Organic Pollutants in Polar Marine Environments

Speaker: Xie Zhiyong (Researcher at the Helmholtz Centre for Coastal Research, Germany)

Date: May 24, 2024 (Friday)

Time: 8:30-10:30 a. m.

Venue: Room 305, Eastern Library

Report Introduction: The presence of a large number of new organic pollutants in the polar and marine environments has become an important topic in current environmental science. Organic pollutants, especially persistent organic pollutants (POPs), due to their chemical stability and persistence, can be transported over long distances globally. These pollutants enter the marine environment through atmospheric long-range transport, air-sea exchange, surface runoff, and oil spills, and are transported to areas far from the pollution sources. In the deep-sea environment, the distribution of organic pollutants is influenced by biogeochemical and geophysical factors, threatening the biogeochemical functions and nutrient cycling functions of the deep sea. The German polar research vessel Polarstern is an important scientific research platform, playing a key role in oceanic and polar scientific expeditions. This report will also introduce the scientific research activities carried out on the German polar research vessel Polarstern and at the Ny-Ålesund Arctic Station.

Introduction to the speaker: Dr. Xie Zhiyong, a researcher at the Helmholtz Centre for Coastal Research in Germany, has been engaged in scientific research in Germany for 20 years. He has long been dedicated to the study of the environmental and biogeochemical behavior of traditional and new organic pollutants in different environmental media. Dr. Xie has participated in several scientific expeditions to the Antarctic and Arctic and has made remarkable achievements in the research on the persistence and long-distance transport mechanisms of organic pollutants in coastal, marine, and polar environments. Dr. Xie’s research on new global pollutants (perfluorinated compounds, new flame retardants, and pharmaceuticals and personal care products) in the coastal-ocean-polar regions is at the forefront internationally. He applies multi-media models to elucidate the biogeochemical cycles of legacy and emerging organic pollutants in polar regions due to climate change and enhanced human activities. He has published numerous scientific papers and is currently focusing on the research of the multi-media occurrence, distribution laws, and control mechanisms of new organic pollutants in polar marine environments.
