Decadal changes in microplastic accumulation in freshwater sediments: Evaluating influencing factors
Researchers analyzed decadal trends in microplastic accumulation using freshwater sediment cores, examining how land use, hydrological factors, and global plastic production influenced deposition over time.

Centennial Records of Microplastics in Lake Cores in Huguangyan Maar Lake, China
Researchers analyzed lake sediment cores from Huguangyan Maar Lake in China to reconstruct a century-long record of microplastic pollution. They found that microplastic accumulation in the sediment closely tracked the history of global plastic production, with a sharp increase beginning in the mid-twentieth century. The study demonstrates that even isolated lakes without direct inlets can accumulate significant microplastic contamination, likely through atmospheric deposition.
Microplastic inventory in sediment profile: A case study of Golden Horn Estuary, Sea of Marmara
Researchers analyzed a 105 cm sediment core from the Golden Horn Estuary using radiodating, finding that over 90% of accumulated microplastics were buried below 15 cm, that MP pollution predated 1950, and peaked in the 1980s coinciding with peak global plastic production.

Analysis of well-preserved Baltic Sea sediment cores revealed a 50-year chronological record of microplastic accumulation, showing contamination onset in the mid-20th century with accelerating deposition in recent decades.
Can a Sediment Core Reveal the Plastic Age? Microplastic Preservation in a Coastal Sedimentary Record
Researchers used a sediment core from the NW Mediterranean Sea combined with state-of-the-art microplastic identification methods to reconstruct the historical record of microplastic pollution down to 11 micrometers in size. The core revealed a clear acceleration in microplastic burial rates since the 1960s and provided evidence that some polymer types are preserved well in sediment.
A temporal record of microplastic accumulation in sediment cores of the Great Lakes, North America, reflects macroeconomic and regional influences
Researchers analyzed sediment cores from Lake Huron and Lake Ontario spanning several decades to track historical trends in microplastic accumulation in the Great Lakes. They found that microplastic levels increased steadily from the 1960s through the late 1980s, mirroring global plastic production rates, with subsequent fluctuations reflecting economic shifts and regional factors. The study demonstrates that lake sediment records can serve as proxies for tracking both global and local changes in plastic pollution over time.
Human activities affect the multidecadal microplastic deposition records in a subtropical urban lake, China
Researchers analyzed sediment cores from a subtropical urban lake in China to reconstruct 64 years of microplastic deposition history. They found that microplastic concentrations in the sediment increased significantly over the decades, correlating closely with urbanization, population growth, and economic development. The study provides evidence that human activities are the primary driver of long-term microplastic accumulation in freshwater lake environments.
The Paleoecology of Microplastic Contamination
This paper reviews how paleoecological methods — using naturally accumulating environmental archives like sediment cores — can be applied to reconstruct the historical timeline of microplastic contamination. Long-term records are needed to establish baselines and understand how rapidly microplastic pollution has escalated over the past century.

Historical reconstruction of microplastic accumulation in shallow lake sediments and its anthropogenic drivers: A case study in Lake Liangzi
Scientists studied lake sediments in China and found that tiny plastic particles (microplastics) have been building up dramatically since the 1980s, with the biggest increases linked to plastic production, population growth, and urban development. This matters because microplastics in freshwater lakes can enter our drinking water and food chain, and this study shows the problem is getting much worse as human activities increase. The research provides clear evidence that our daily activities are the main cause of plastic pollution accumulating in the water sources we depend on.
