Research news on microplastic contamination

Microplastic contamination refers to the presence and distribution of synthetic polymer particles typically <5 mm in environmental matrices, including marine, freshwater, terrestrial, atmospheric, and biological systems. As a research topic, it encompasses sources (primary and secondary microplastics), transport pathways (e.g., hydrodynamic and atmospheric dispersion), physicochemical properties (size, shape, polymer type, surface chemistry), and interactions with co-contaminants such as persistent organic pollutants and metals. Studies investigate bioavailability, trophic transfer, organismal and cellular responses, and potential human exposure via inhalation and ingestion, as well as methodological challenges in sampling, analytical detection, quantification, and risk assessment frameworks.

Wild bird eggs reveal pollutants' environmental footprints

Monitoring the eggs of wild birds like the bearded vulture and the imperial eagle over a decade reveals the accumulation and persistence of environmental pollutants in ecosystems. At first glance, a wild bird's egg represents ...

Toward standardized microplastics monitoring in rivers

Microplastics (MPs), defined as plastic fragments smaller than 5 mm, have become so pervasive that they are detectable in nearly every environment studied—from remote ocean trenches to urban air, tap water, and human blood. ...

The impact of nanoplastics on neurons may depend on their size

Smaller plastic particles have more effects on neurons, the key information processing cells of the brain, new research from the University of Eastern Finland shows. In the study, neuronal cells were exposed to polystyrene ...

The impact of microplastics on ocean carbon uptake

Marine microplastics affect algae's ability to grow and photosynthesize. Researchers have now calculated what impact this has on the greenhouse effect and the ocean's ability to absorb carbon dioxide.

DR Congo fishermen resort to trawling plastic waste

The mighty Congo River feeds millions of people along its course through the vast Democratic Republic of Congo but fishermen near the capital now find more plastic than fish in their nets.
