Jun 27, 2024 · Microplastics have been detected in fruits and vegetables, plastic water bottles, the air, cosmetics, and household dust. Now, researchers are finding them in almost every part of the human body, including in breast milk, the placenta, testicles, hearts, livers, and kidneys.

We encounter microplastics everywhere: from trash, dust, fabrics, cosmetics, cleaning products, rain, seafood, produce, table salt, and more. Little wonder that microplastics have been detected throughout the human body, including in the blood, saliva, liver, kidneys, and placenta.

Apr 28, 2023 · One of the most damaging and long-lived legacies of the plastic pollution crisis is microplastics, a growing threat to human and planetary health. These tiny plastic particles are present in everyday items, including cigarettes, clothing and cosmetics.

Dec 1, 2020 · What are microplastics, and where do they come from? “As their name suggests, microplastics are tiny plastic particles less than five millimeters in size,” says Dr. Leigh Shemitz (MFS ‘92, PhD. ’04), President of SoundWaters .
