Key Points

To investigate how polyethylene microplastics influence heavy metal enrichment and ecological risks in recessed green spaces.
Analyzed stormwater runoff for microplastic and heavy metal concentrations.
Assessed the enrichment of Cu2+, Cd2+, and Pb2+ by polyethylene microplastics in a representative low-impact development facility.
Conducted ecological risk assessments based on pollution load index and potential ecological risk index.
PE microplastics enriched heavy metals in the order Pb2+ > Cu2+ > Cd2+.
Significant correlations were observed between heavy metal concentrations and temperature, pH, while larger PE particles showed less efficiency in adsorption.
Pollution load index increased under combined microplastic and heavy metal exposure, indicating a rise in ecological risks.
