|Microplastics found in human heart for first time
Many of us are aware of the harm plastic does to the environment. Fewer people know about the threat from the microplastics. Scientists found them in our bodies more than a decade ago. Researchers have now found them in the human heart. Scientists in China collected tissue samples from patients undergoing heart surgery. They discovered tiny pieces of plastic from many sources. They included a plastic commonly used in an alternative to glass, a polythene used in clothing and food containers, and a substance used in construction.
