A detailed graphical abstract illustrating the microplastic lifecycle. At the top, "Anthropogenic Sources" like plastic waste, textiles, tires, and agriculture release primary and secondary microplastics. A central circular diagram shows their transport through Marine, Freshwater, Terrestrial, and Atmospheric compartments, highlighting chemical adsorption and microbial colonization. The bottom section depicts a food-chain transfer web leading to a human silhouette, illustrating exposure via ingestion and inhalation, resulting in systemic distribution and inflammatory responses.
