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 ...
Woodruff, who has studied the effect of some chemicals found in plastics on human health, reproduction, and development for two decades, first started looking into microplastics in 2021.
Finding microplastics in human body parts is not new: Scientists have uncovered the minuscule waste products in human blood, lungs, brains, hearts and testicles. But a new study, published Monday ...
Microplastics are everywhere—from the ocean to our bloodstream—raising urgent questions about their impact on human health. Here are 5 tips to reduce your exposure.
Professor Fay Couceiro leads a team that researches the potential health impacts of microplastics. Not microwaving food in plastic is just one way she reduces her exposure.
Microplastics are likely to degrade into smaller nanoplastics through chemical weathering processes, mechanical breakdown, and even through the digestive processes of animals. Nanoplastics, or NPs, are a subset of microplastics and they are smaller than 1 μm (1 micrometer or 1000 nm). Nanoplastics cannot be seen by the human eye. [4]
The plastisphere is a human-made ecosystem consisting of organisms able to live on plastic waste. Plastic marine debris, most notably microplastics, accumulates in aquatic environments and serves as a habitat for various types of microorganisms, including bacteria and fungi.
The Food and Drug Administration said in a statement: “Current scientific evidence does not demonstrate that levels of microplastics or nanoplastics detected in foods pose a risk to human health.”
