- In the toxicokinetics studies, thifensulfuron-methyl was extensively and rapidly absorbed.
- Excretion of substance was predominantly through the urine but with appreciable amounts excreted in faeces (European Food Safety Authority, 2015).
- Available data indicates that Thifensulfuron-methyl generally exhibits lower acute toxicity to mammals, birds, and fish compared to the older chemistries, particularly the ester formulations of 2,4-D (BenchChem, 2025).
- In the acute toxicity studies, the substance has low acute toxicity when administered orally, dermally or by inhalation to rats (LD50 > 5000 mg/kg bw, LD50 > 2000 mg . . .
