Microplastics in 29 Great Lakes tributaries (2014-15)

AI summary Read the abstract

This dataset describes the quantity and morphology of floating microplastics sampled from 29 tributaries of the Great Lakes across six U.S. states during spring 2014 and 2015, capturing both low-flow and runoff-event conditions. The dataset provides a broad spatial picture of microplastic inputs to the Great Lakes from tributary rivers under varying hydrological conditions.

This dataset describes the quantity and morphology of floating microplastics in 29 Great Lakes tributaries in 6 states. Samples were collected in spring 2014 spring 2015. Each tributary was sampled three to four times, capturing low-flow and runoff-event conditions. Sampling and analysis methods are described in the .xml metadata file. These data are interpreted in a journal article (pending).

Factors controlling the abundance, distribution, and composition of macroplastic and microplastic particles in tributary, beach, and benthic sediments of Lake Erie, Ontario

AI summary Read the abstract

This study examined the factors controlling the abundance, distribution, and composition of microplastics in tributary, beach, and benthic sediments of Lake Erie, finding that urban tributaries contained more microplastics than rural ones and that backshore beach zones accumulated more plastic than foreshores. The findings highlight how watershed urbanization and beach dynamics control microplastic distribution in one of North America's largest freshwater lakes.

Size Distributions of Microplastics in the St Louis Estuary and Western Lake Superior

AI summary Read the abstract

Researchers mapped the sizes, shapes, and types of microplastics in western Lake Superior and its harbor, finding roughly similar overall counts but meaningful differences in composition. Harbor samples near urban areas had larger particles and more diverse plastic types, while standard counting methods significantly underestimated the smallest particles (under 45 micrometers), highlighting gaps in how we measure microplastic pollution in freshwater.

Temporal distribution and seasonal fluxes of microplastics in the sediments of UK rural and urban lakes

AI summary Read the abstract

The temporal distribution and seasonal fluxes of microplastics in the sediments of an unnamed urban waterway were quantified, revealing patterns in how microplastic accumulation varies with season, runoff, and flow conditions. The findings highlight how urban water systems act as sinks and transport pathways for microplastic pollution.

Proportion of microplastics by shape (fiber, fragment and sphere) for A.

AI summary Read the abstract

Researchers documented the proportion of microplastics by morphological shape — fiber, fragment, and sphere — across 11 sites in the St. Lawrence River and Estuary using 300 µm and 100 µm mesh nets, comparing distributions from upstream to downstream. The dataset illustrates spatial variation in microplastic shape composition across fluvial and estuarine environments.
