APVMA has summarised the toxicological and environmental effects of cloquintocet acid, a novel herbicide active ingredient. An acceptable daily intake (ADI) for the sum of the acid and its esters was established at 0.04 mg/kg bw (as cloquintocet-mexyl) based on thyroid effects in chronically exposed rats. Because of its low acute toxicity, an acute oral reference dose (ARfD) for cloquintocet acid was considered unnecessary.
