Anthropogenic sediments refer to sedimentary materials that are altered, created, or influenced by human activities. These sediments can result from urbanization, industrial processes, agriculture, and other human interventions, impacting natural sedimentation processes and ecosystems.

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.

Key finding: This study analyzed well-dated sediment cores from three lakes in northeastern Europe using 210Pb and other proxies, finding microplastic particles throughout sediment layers including those predating 1950, indicating... Read more
Key finding: By employing multiple dating proxies (210Pb, spheroidal carbonaceous particles) and sediment core profiling from lakes with differing anthropogenic pressures, this research confirmed the widespread presence of microplastics... Read more

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.

Key finding: Chemical and palaeobotanical analyses of sediments from four lakes of varying origin revealed discernible anthropogenic signatures primarily in upper sediment layers, with impacts traceable to urban and industrial... Read more
Key finding: The study documented the spatial variability of sedimentary organic matter (SOM) across the Vembanad Lake, India, showing a shift from marine-derived to terrestrial and aged soil-derived organic components influenced by... Read more
Key finding: A comprehensive two-year survey across three sections and two zones of Owalla Reservoir identified that sediments are predominantly clayey-sand with a particle size order of sand > clay > silt, and chemically acidic, low in... Read more
Key finding: This study corroborated prior findings evidencing that sediment physico-chemical properties within Owalla Reservoir exhibit spatial-temporal variability linked to human impacts. Nutrients were predominantly of anthropogenic... Read more
Key finding: Analyzing heavy metals, PAHs, and PCBs in coastal sediments relative to regional standards and sediment quality guidelines identified selective contamination exceeding threshold levels in harbor sediments, primarily Cu, Ni,... Read more

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.

Key finding: Interviews with coastal sediment managers and regulators in Southern California identified key regulatory complexities, technical uncertainties, stakeholder perceptions, and institutional fragmentation as major barriers... Read more
Key finding: This review delineates that while unpolluted sediments hold promise for agricultural reuse due to their organic matter and nutrient content, significant legislative gaps, the presence of residual pollutants (metals, organic... Read more

Quantitative analysis, in its most general form, differs from qualitative an- alysis in the following way: while qualitative analysis is based on absolute properties (e.g. presence/absence) quantitative analysis concerns itself with... more
Archaeologists have employed sediment chemistry in site prospection for nearly a century. For example, phosphorus is a good indicator of human occupation, because it is a generic indicator of human activity. Recently, multi-element... more
