Furthermore, geophagous soil fauna, such as earthworms, mites, and collembolans could contribute to the amount of secondary microplastic present in soil by converting consumed plastic debris into microplastic via digestive processes. Further research, however, is needed.
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 ] [ 33 ] Fecal sample analyses estimate a daily intake of approximately 203–332 MNPs, translating to an annual ingestion rate of around 39,000–52,000 particles.
A more recent concern in microplastic pollution is the use of plastic films in agriculture. 7.4 million tons of plastic film are used each year to increase food production. [22] Scientists have found that microbial biofilms can form within 7–14 days on plastic film surfaces, and have the ability to alter the chemical properties of the soil ...
New study: As global plastic production grows, so too does the concentration of microplastics in our bodies. As global plastic production grows, so does the concentration of microplastics in our ...
How does plastic get into the brain? The researchers do not know how microplastics get into the brain. In general, it's believed microplastic particles enter the body when people eat, drink, or ...
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 ...
Polystyrene is not biodegradeable but is susceptible to photo-oxidation, and degrades slowly in the ocean as microplastic marine debris. Animals do not recognize polystyrene foam as an artificial material, may mistake it for food, and show toxic effects after substantial exposure.
The prevalence of tiny plastic particles, ranging in size from a billionth of a metre to a millionth of a meter, has increased exponentially over the last 50 years, yet their toxic effects on ...
