New research measures how much plastic is lethal for marine life
Marine animals inevitably eat what we toss in the ocean, including pervasive plastics—but how much is too much?
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 year humanity produces nearly 300 million tons of plastic. Only a fraction ever gets recycled. Most ends up in rivers, oceans and soil, slowly breaking down into tiny, invisible microplastics that get into what we eat ...

Researchers at the University of Toronto have found that Toronto's Don River carries over 500 billion microplastic particles into Lake Ontario each year—equal to about 36,000 kilograms, or the weight of 18 cars.

At first glance, the tiny plastic pellets appear relatively harmless. No bigger than a lentil, these "nurdles" are destined to be melted down to make everything from car bumpers to salad bowls.
