Microplastics, or tiny pieces of plastic, have been linked to many human health problems. Laboratory experiments now suggest a possible explanation for how they may harm the body. These particles can react with water inside us, producing molecules that react readily with other substances.
These highly reactive molecules can lead to oxidative stress, a process that can cause damage in the body. They can also lead to inflammation, a response that can involve swelling and irritation. The experiments suggest that a reaction between plastic and water may help explain the harmful effects associated with these tiny particles.
