Beyond Rapid Degradation: The Underestimated Ecological Risk of Sodium dehydroacetate on Soil Microbiome and Gene Horizontal Transfer

This study systematically examines the adsorption and degradation dynamics of Na-DHA in soil and evaluates the ecotoxicological effects of its transformation products. We further assess its impact on microbial activity, community structure, antibiotic resistance genes (ARGs), and the abundance of functional genes.
