Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
[67] [68] [69] The primary source of human exposure is via food, as epoxy and PVC are used to line the inside of food cans to prevent corrosion of the metal by acidic foodstuffs. Polycarbonate drink containers are also a source of exposure, although most disposable drinks bottles are actually made of PET, which contains no BPA.
In 2003, U.S. consumption was 856,000 tons, 72% of which used to make polycarbonate plastic and 21% going into epoxy resins. [8] In the U.S., less than 5% of the BPA produced is used in food contact applications, [9] but remains in the canned food industry and printing applications such as sales receipts.
The brain is the most well-protected organ in the human body, but it has a surprisingly high amount of microplastic pollution, ... which is used in plastic bags, plastic food wrapping, ...
Contamination is further compounded by plastic packaging and storage materials, which can leach MNPs over time, leading to additional ingestion from common foods and drinks. [10] [27] Fecal sample analyses estimate a daily intake of approximately 203–332 MNP particles, translating to an annual ingestion rate of around 39,000–52,000 particles.
Polyethylene — a plastic polymer used to make things such as plastic bags, milk jugs, shampoo bottles, etc. — was the most common microplastic found in the brain.
The brain may contain higher -- and more significant -- amounts of microplastics than other organs in the body, according to a new study. Researchers from the University of New Mexico Health ...
A plastic bottle of antifreeze Large plastic bottles of water. A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo or milk. They range in sizes, from very small bottles to large carboys.
