Quantifying and tracking PBAT microplastic degradation in soil. A newly developed thermal-assisted alkali hydrolysis and LC–MS method enables accurate quantification of PBAT microplastics and their degradation products in soil. The study revealed that PBAT degraded more rapidly in alkaline soils (up to 17.1% after 150 days) than in neutral or acidic soils, while metabolites such as terephthalic acid (TPA) and 1,4-butanediol accumulated during the process. This approach provides an efficient tool for evaluating the environmental fate of biodegradable microplastics..
