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 nanoplastics (NP), particles smaller than 1000 nm in diameter (0.001 mm or 1 μm ...
This process of breaking down large plastic material into much smaller pieces is known as fragmentation. [32] It is considered that microplastics might further degrade to be smaller in size, although the smallest microplastic reportedly detected in the oceans in 2017 was 1.6 micrometres (6.3×10 −5 in) in diameter.

If the plastic is etched — a well-used plastic cutting board or a cracked lid, for example — definitely toss it because etching increases the odds of chemicals leaching into your food, too, he ...
BPA can be released into the environment by both pre-consumer and post-consumer leaching. Common routes of introduction from the pre-consumer perspective into the environment are directly from chemical plastics, coat and staining manufacturers, foundries who use BPA in casting sand, or transport of BPA and BPA-containing products .
Bisphenol A can leach into food from the linings of canned foods, polycarbonate tableware, food storage containers and water bottles, according to the National Institute of Environmental Health ...
“One is the plastic bottle itself,” Rumpler says. “There is some evidence to suggest that microplastics are in plastic bottled water — that’s a problem.” Plastic water bottles can also ...
The largest exposure humans have had to BPA is from food packaging, particularly the epoxy lining of metal food, beverage cans and plastic bottles. As a result of the presence of BPA in plastics and other commonplace materials, most people are frequently exposed to trace levels of BPA.
The study found such chemicals as benzene, a known carcinogen connected to breast cancers in animals and people; 4,4’-Methylenebis-(2-Chloroaniline), a probable carcinogen linked to bladder ...
