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.
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]
A 2018 study found that tap water has fewer microplastics than bottled water, making it a likely better bet. Filtering your water is another possible way to decrease microplastics in drinking water.
Another study capable of detecting nanoplastics found 240,000 fragments per liter: 10% between 5 mm and 1 μm and 90% under 1 μm in diameter. [ 74 ] [ 75 ] Some of the contamination likely comes from the process of bottling and packaging the water, [ 73 ] and possibly from filters used to purify the water.
People with nanoplastics in their arteries were twice as likely to have a heart attack, stroke or die early from any cause, a new study found. Nanoplastics linked to heart attack, stroke and early ...
As Bryan E. Cummings and Michael S. Waring, the authors of the Drexel study, found, you would need 10–100 plants per square meter to clear the air in the way the NASA study reported.
A study conducted by Scripps Institution of Oceanography showed that the average plastic content in the stomachs of 141 mesopelagic fish over 27 different species was 9.2%. Their estimate for the ingestion rate of plastic debris by these fish in the North Pacific was between 12,000 and 24,000 tonnes per year. [ 195 ]
The study by researchers at Johns Hopkins University raises new health concerns for communities that sit among the chemical plants lining a stretch of the Mississippi River between Baton Rouge and ...
