The quality of water in urban parks is closely related to people's daily lives, but the pollution caused by microplastics park and sediments has not been comprehensively studied. Therefore, eight typical area Changsha, China, were selected, Raman spectroscopy was used explore spatial distributions compositions sediments, analyze their influencing factors, evaluate environmental risks. results showed that abundances surface all ranged from 150 525 n L
