Systematic Revelation of the Metabolic Fate of Typical Quaternary Ammonium Compounds in Wheat Seedlings
-OH-DBAC, with root concentrations 1.8-4.3 times and shoot concentrations 3.0- 3.9 times higher, demonstrating regioselective internal hydroxylation distinct from microbial pathways (α/ω-hydroxylation). Similar patterns were observed for DTAC (21 metabolites) and DDAC (45 metabolites), further underscoring the role of alkyl chain number. These findings provide the first systematic insight into QAC fate in crops, essential for risk assessment of cationic pollutants.
