Key research themes
1. How can microplastics in lake sediments serve as chronostratigraphic markers of the Anthropocene?
This research theme examines the presence, distribution, and characteristics of microplastic particles (MPs) in lake sediment profiles to evaluate their potential as chronological proxies marking the onset and development of the Anthropocene Epoch, particularly focusing on sediments dated around and before the mid-20th century. Understanding MPs in stratigraphy is crucial for refining geological markers of human impacts and defining the Anthropocene boundary in sedimentary records.
2. What are the impacts of anthropogenic activities on sediment composition and quality in freshwater and marine systems?
This theme focuses on characterizing how human-induced changes—such as industrialization, urbanization, land use change, and pollution—alter the physical, chemical, and organic composition of sediments in lakes, reservoirs, estuaries, and coastal areas. Understanding sediment alterations is vital for interpreting environmental history, assessing pollution levels, managing aquatic ecosystems, and guiding remediation and sediment reuse efforts.
3. What are the barriers and opportunities for beneficial reuse and recycling of anthropogenic sediments?
Research in this area investigates the regulatory, technical, environmental, and social challenges constraining the beneficial reuse of sediments dredged from urban, coastal, and aquatic systems. It evaluates sediment properties, contamination risks, management frameworks, and potential sustainable applications such as agriculture, coastal restoration, and infrastructure. Understanding these dimensions informs policy and practical strategies for revalorizing sediments rather than disposal, balancing ecological safety and resource recovery.
