Edition 1/2023, current as of 31 March 2023
Introduction
The acute reference doses for agricultural and veterinary chemicals (ARfD list) provides a tabulation of acute reference doses (ARfDs; in units of mg/kg bodyweight) for each agricultural or veterinary (agvet) chemical listed.
The ‘Date’ column indicates when particular ARfDs were established.
The 'Study' column provides information about the pivotal study, including type, the NOAEL (no-observed-adverse-effect level) and the critical toxicological endpoint. For some agvet chemicals, longer-term rather than acute dosing studies have been used to establish the ARfD. In these cases, the NOAEL was selected on the basis of toxicological effects observed after the first dose.
The ‘Comments’ column may:
- provide additional information about its applicability to the general population
- advise that an ARfD is not necessary
- indicate that the ARfD has been adopted from that established by the FAO/WHO Joint Meeting on Pesticide Residues (JMPR).

Abamectin (sum of abamectin + 8,9–Z Isomer) |
0.002 |
0.25 |
6 August 2018 |
Based on the overall NOAEL of 0.25 mg/kg bw per day for clinical signs in dogs (mydriasis) observed in the first week of treatment at 0.5 mg/kg bw per day. |
A total uncertainty factor of 100 has been applied. The ARfD also applies to the 8,9–Z isomer of avermectin B1a and 24-hydroxymethyl abamectin. The 24-hydroxymethyl metabolite of abamectin is regarded as having no greater toxicity than the parent molecule. |
|
Acephate |
0.1 |
≥ 1.2 |
2005 |
Single dose study in humans. No inhibition of erythrocyte acetylcholinesterase activity was reported in either sex at any dose. No clinically significant changes were seen in vital signs or on electrocardiography, haematology, clinical chemistry, urine analysis or physical examination. The NOAEL was 1.2 mg/kg bw per day, the highest dose tested. |
The critical toxicological effect of acephate is the inhibition of acetylcholinesterase activity in the nervous system, an effect that is dependent on Cmax rather than on the area under the curve (AUC). Data on inhibition in vitro indicate that human brain acetylcholinesterase is slightly less sensitive to inhibition by acephate than is rat brain acetylcholinesterase. Well conducted toxicokinetics studies, available for both rats and humans, show that there is no significant difference between the two species; in particular, Cmax values have the same relationship to administered dose in the two species, and acephate is rapidly absorbed and eliminated in both species. Data for rats in vivo indicate that inhibition of brain acetylcholinesterase activity occurs at lower doses than those required for a similar level of inhibition of erythrocyte acetylcholinesterase activity. Data for dogs and monkeys in vivo indicate that brain and erythrocyte acetylcholinesterase activities are nearly equally inhibited at any given dose, and do not show the difference seen in rats, which might thus be rat-specific. Well-conducted single and repeated-dose studies in humans clearly demonstrated a dose where no inhibition of blood cholinesterase activities occurred. Data from animals in vivo do not show sex differences in inhibition of acetylcholinesterase activity or clinical signs. Since there is no interspecies extrapolation, an overall safety factor of 10 was used. |

30 August 2018 |
An ARfD of 0.3mg/kg bw was established based on a NOAEL of 30mg/kg bw per day in a developmental toxicity study in rats and a 100-fold safety factor. The NOAEL was identified on the basis of slight increases in rudimentary ribs and unossified sternebrae at 90mg/kg bw per day. This provides an adequate margin over the maternal toxicity and cleft palate seen at 300mg/kg bw per day. The NOAEL is also adequately protective against any acute local effects on the gastrointestinal tract based on the available data in dogs. Ataxia has also been noted in pregnant rats dosed at 360 mg/kg body weight/day. |

ARfD for prothioconazole only applies to women of child-bearing age. An ARfD for the general population is considered to be unnecessary.
