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 ...
A new study in the journal Frontiers in Toxicology found that microplastics in the fish we consume are ... those microplastics make their way into the environment and are taken up by things we eat ...

Degraded plastic waste can directly affect humans through direct consumption (i.e. in tap water), indirect consumption (by eating plants and animals), and disruption of various hormonal mechanisms. [12] As of 2019, 368 million tonnes of plastic is produced each year; 51% in Asia, where China is the world's largest producer. [13]
Plastivores are "organisms that use plastic as their primary carbon and energy source". [3] This does not necessarily mean being able to fulfill all biological needs from plastic alone.
Some of these toxic chemicals are discharged into lakes, rivers, the ocean, and groundwater. Animals, plants, and water surfaces can also be exposed from airborne chemical emissions caused from cities, factories, and fires (Fantke, 2020). Chemical sludge often gets into agricultural and industrial soils as well. [citation needed]
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 which then enter the marine food chain, including the fish that some humans eat. [37]
In general, people can safely eat one serving of Ohio-caught fish every week (or four servings per month). They suggest the best fish to choose from grocery stores and restaurants are tuna, salmon ...
