Microplastic contamination in urban agriculture: Pathways, crop uptake, human exposure and policy interventions

Key Points

• Microplastic contamination impacts crop uptake significantly, potentially affecting human health.
• Crop uptake of microplastics was observed in various urban agriculture settings, raising exposure concerns.
• Analysis of urban farms documented multiple contamination pathways, including soil and water sources.
• Effective policy interventions are needed to mitigate microplastic pollution in agricultural practices.
