Microplastic contamination refers to the presence and distribution of synthetic polymer particles typically <5 mm in environmental matrices, including marine, freshwater, terrestrial, atmospheric, and biological systems. As a research topic, it encompasses sources (primary and secondary microplastics), transport pathways (e.g., hydrodynamic and atmospheric dispersion), physicochemical properties (size, shape, polymer type, surface chemistry), and interactions with co-contaminants such as persistent organic pollutants and metals. Studies investigate bioavailability, trophic transfer, organismal and cellular responses, and potential human exposure via inhalation and ingestion, as well as methodological challenges in sampling, analytical detection, quantification, and risk assessment frameworks.
Plastics are everywhere—from packaging and textiles to electronics and medical devices. As plastic waste breaks down, it releases microscopic particles that can penetrate our ecosystems, hinder plant growth, and potentially ...
