Spatial-temporal distribution of microplastics in dust of Zhengzhou: Insights into occurrence characteristics, physicochemical properties and ecological risks

Key Points

• Microplastics were found in various concentrations throughout Zhengzhou dust, showing notable variation across locations and times.
• Key physicochemical properties were analyzed to determine the nature and impact of these microplastics on the environment and human health.
• Assessment revealed complex patterns in both spatial and temporal distribution, influencing environmental pollution levels.
• Findings highlight potential ecological risks associated with increasing microplastic prevalence; further studies are warranted to assess long-term effects.
