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.
Every summer, algal blooms turn rivers and lakes green. Although they are widely known as a major form of water pollution that makes water murky, a KAIST research team has now shown for the first time that algal bloom conditions ...

That kitchen sponge sitting by your sink is not as innocent as it looks. It could be harboring Salmonella enteritidis, E. coli or Staphylococcus aureus—and there's no way to tell just by looking at it or smelling it.

Microplastic contamination has been a much-discussed topic over the last several years, but contamination from even smaller plastic particles represents another pressing issue. Nanoplastics—defined as being under a micrometer ...
When colleagues and I found microplastics in hedgehog droppings, we wanted to know where they were coming from. One answer was surprisingly close to home: pet food.

Micro- and nanoplastics are now popping up everywhere: in seawater, snow, food and even in our bodies. The very smallest particles, in particular, are difficult to measure, meaning we still know too little about their spread ...
