A Theoretical Framework for Bio-Magnetic Filtration of Microplastics in Urban Irrigation Systems: I nsights from a Systematic Review

Summary

Tiny plastic bits from city runoff are ending up in irrigation water and farm soil, which means they could work their way into the food we grow and eat. This paper reviews existing research to propose a new idea: using magnetic filters combined with natural materials to catch these microplastics before they contaminate crops. It's a promising concept on paper, but it's a theoretical framework based on other studies rather than a tested, real-world solution—so more research is needed before we see it used in the field.
