These microplastics are frequently consumed by marine organisms at the base of the food chain, like plankton and fish larvae, which leads to a concentration of ingested plastic up the food chain. Plastics are produced with toxic chemicals, so these toxic substances enter the marine food chain, including the fish that some humans eat. [39]

Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues. Microplastics, defined as plastic fragments smaller than 5 mm, and even smaller particles such as ...
That is a key point that both Gaver and McKinney stress: recycling should not be the number-one option when it comes to attacking the problem of microplastics. “Once you get to recycling, every ...
Microplastics have been found in the ocean and the air, in our food and water. Dr. Marya Zlatnik, a San Francisco-based obstetrician who has studied environmental toxins and pregnancy, has seen ...
Microplastics have been found in dolphin breath, suggesting the animals could be exposed to the potentially harmful particles through inhalation.
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
Microplastics can interact with antioxidant enzymes like catalase, potentially altering their activity and thus disrupting the cellular redox balance. [81] In 2020 some suggested, ingestion of microplastics via food might be relatively minor; with humans predicted to be exposed to more microplastics in household dust than by consuming mussels ...
