As emerging pollutants, microplastics are pervasive in marine, terrestrial, and atmospheric environments as well human tissues due to their small size, large specific surface area, strong adsorption capacity. Consequently, developing efficient rapid methods for identifying differentiating is critical. Herein, a novel pyrolysis-assisted cataluminescence (CTL) sensor array was constructed, capable of efficiently distinguishing seven distinct types microplastic samples. By pyrolyzing at high temperatures into molecular compounds introducing them the CTL array, which based on 0–9% Eu3+-doped LaAlO3 sensing materials, system achieved response time no more than 2 s an average recovery approximately 7 s. Through integration thermodynamic (signal-to-noise ratio) kinetic (response time) factors from curves, unique fingerprint patterns were generated, enabling high-throughput differentiation multiple microplastics. Mechanistic studies revealed that doping with Eu3+ ions played dominant role regulating signal. Different samples generated concentrations reaction intermediates during process, leading variations luminescence efficiency thus forming patterns. The proposed front-end pyrolysis combined back-end method provided valuable insights structurally complex low-reactive particularly nonvolatile solid samples, thereby expanding application scope detection.

In the past decade, microplastics (MPs) have drawn significant attention as widespread environmental contaminants, with research increasingly highlighting their harmful effects on respiratory health in aquatic and terrestrial organisms. Findings revealed human lung tissues, raising concerns about potential role damaging tissue integrity contributing to pulmonary fibrosis-a chronic inflammatory condition characterized by scarring of epithelial tissues due accumulated extracellular matrix, triggered factors such alcohol, pathogens, genetic mutations, pollutants. this review, we explore both well-studied lesser-studied mechanisms signaling pathways, aiming shed light how might act mediators that activate distinct, often overlooked cascades. This review searched PubMed Google Scholar using keywords like "plastic," "microplastic," "lung fibrosis," "pulmonary system," "exposure route," "signaling pathways," combined "OR" "AND" singular plural forms. These pathways could not only induce damage but also play a development fibrosis. be targeted reduce microplastic-induced fibrosis, opening new avenues for future treatments.
