Are Microplastics in Our Brains and Bodies?

Microplastics are everywhere—including in our brains and bodies. Researchers have found them in all human tissue systems, and even in meconium, a newborn’s first bowel movement. But what does this mean for human health? The answer isn’t clear yet. Because microplastics are so widespread, it's hard for scientists to tell whether they’re causing health problems—or simply present by coincidence. However, one recent study suggests a possible link between microplastics and cardiovascular disease.
