Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Oral
DNEL related information

- ECHA REACH Guidance
- Dose descriptor starting point:
- NOAEL
- Value:
- 10 mg/kg bw/day
- Modified dose descriptor starting point:
- NOAEC
- Value:
- 12.3 mg/m³
- Explanation for the modification of the dose descriptor starting point:
A NOAEL of 10 mg/kg bw /day was derived based on a subchronic oral repeated dose toxicity study in rats available for the source substance Fe(Na)EDDHA (Novartis Crop Protection AG, 1998). This value was converted into the corrected inhalatory NOAEC taking into account the standard respiratory factor of 1/0.38 m³/kg/day, the absorption rates (based on the ECHA Guidance R.8 the inhalative absorption is considered to be higher by a factor of 2 than the oral absorption as worst-case assumption) and the standard respiratory volume in humans/ worker respiratory volume (6.7 m³ (8 h) / 10 m³ (8 h)) and the correction factor between human and experimental exposure conditions of workers (5 working days vs. 7 days continuous exposure) of 1.4.
NOAEC corrected = 10 mg/kg bw/day * 1/0.38 m³/kg/day * 0.5 * (6.7 m³/10 m³) * 1.4 = 12.3 mg/m³
- Justification:

- Explanation for the modification of the dose descriptor starting point:
A NOAEL of 10 mg/kg bw /day was derived based on a subchronic oral repeated dose toxicity study in rats available for the source substance Fe(Na)EDDHA (Novartis Crop Protection AG, 1998). This value was converted into the corrected dermal NOAEL taking into account the absorption rates (based on the physicochemical properties and toxicological profile, an oral absorption rate of 100 %, and a dermal absorption rate of 10 % are assumed as worst-case assumptions) and the correction factor between human and experimental exposure conditions of workers (5 working days vs. 7 days continuous exposure) of 1.4.
NOAEL corrected = 10 mg/kg bw/day * 100/10 * 1.4 = 140 mg/kg bw/day

- Value:

- Value:
- 4.35 mg/m³
- Explanation for the modification of the dose descriptor starting point:
A NOAEL of 10 mg/kg bw /day was derived based on a subchronic oral repeated dose toxicity study in rats available for the source substance Fe(Na)EDDHA (Novartis Crop Protection AG, 1998). This value was converted into the corrected inhalatory NOAEC taking into account the standard respiratory factor of 1/1.15 m³/kg/day and the absorption rates (based on the ECHA Guidance R.8 the inhalative absorption is considered to be higher by a factor of 2 than the oral absorption as worst-case assumption).
NOAEC corrected = 10 mg/kg bw/day * 1/1.15 m³/kg/day * 0.5 = 4.3 mg/m³

A NOAEL of 10 mg/kg bw /day was derived based on a subchronic oral repeated dose toxicity study in rats available for the source substance Fe(Na)EDDHA (Novartis Crop Protection AG, 1998). This value does not have to be corrected as the oral absorption rate of rats and humans are considered to be identical (100 % as worst-case assumption).
