A growing body of scientific evidence shows that microplastics are accumulating in critical human organs, including the brain, leading researchers to call for more urgent actions to rein in plastic pollution. From a report: Studies have detected tiny shards and specks of plastics in human lungs, placentas, reproductive organs, livers, kidneys, knee and elbow joints, blood vessels and bone marrow. Given the research findings, “it is now imperative to declare a global emergency” to deal with plastic pollution, said Sedat Gundogdu, who studies microplastics at Cukurova University in Turkey. Humans are exposed to microplastics — defined as fragments smaller than 5mm in diameter — and the chemicals used to make plastics from widespread plastic pollution in air, water and even food.
The health hazards of microplastics within the human body are not yet well-known. Recent studies are just beginning to suggest they could increase the risk of various conditions such as oxidative stress, which can lead to cell damage and inflammation, as well as cardiovascular disease. Animal studies have also linked microplastics to fertility issues, various cancers, a disrupted endocrine and immune system, and impaired learning and memory.
