Scientists estimate there are 8-10 million metric tons of plastics in the oceans, and some of that is consumed by fish and other wildlife. Microplastics have been detected in fruits and vegetables ...
The increasing presence of nanoplastics in the environment has raised concerns about their potential impacts on human health. Research has shown that nanoplastics can penetrate biological barriers, induce toxicity, and accumulate in organs, leading to various health issues. [8]
Nanoplastics are lipophilic and models show that polyethylene nanoplastics can be incorporated into the hydrophobic core of lipid bilayers. [46] Nanoplastics are also shown to cross the epithelial membrane of fish accumulating in various organs including the gallbladder, pancreas, and the brain.
Other studies have found micro- and nanoplastics in fruit and vegetables such as carrot, lettuce, broccoli, potatoes, apples, and pears—likely from the concentrations of plastics found in soil ...
The most popular mesopelagic fish is the lantern fish. It resides in the central ocean gyres , a large system of rotating ocean currents. Since lantern fish serve as a primary food source for the fish that consumers purchase, including tuna and swordfish, the plastics they ingest become part of the food chain.
Past studies show that microplastics and nanoplastics can be harmful to human health. A new study has found that humans tend to have higher concentrations of microplastics in the brain compared to ...
The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
Nanoplastics are the most worrisome plastics for human health, experts say. At 1,000th the average width of a human hair, the minuscule bits can migrate through the tissues of the digestive tract ...
