General
DNEL derivation for the test item is performed under consideration of the recommendations of ECHA, Guidance on information requirements and chemical safety assessment, Chapter R.8: Characterization of dose-response for human health (Version: 2.1, November 2012).
Inhalation
Long term, systemic DNEL – exposure via inhalation (workers)
Using a conservative approach, a worker DNEL (long-term inhalation exposure) is calculated. This worker long-term DNEL is considered to ensure an appropriate level of protection with regard to acute inhalation exposure (no high peaks of exposure expected).
No repeated dose inhalation toxicity study with the target substance is available. Therefore, it will be necessary to obtain a long-term dermal DNEL by route-to-route extrapolation:
In a study according to OECD TG 422 the target substance was administered daily as an aqueous preparation to groups of 10 male and 10 female Wistar rats (F0 animals) by gavage at doses of 100, 300 and 1000 mg/kg bw/day. The NOAEL for reproductive performance and fertility of the F0 parental rats and developmental toxicity in the offspring was 1000 mg/kg bw/day, the highest dose tested. The NOAEL for general, systemic toxicity of the test item was 100 mg/kg bw/day based on the findings in the target organ kidney. This NOAEL systemic is used as PoD for DNEL derivation.
Step 1: PoD: NOAEL = 100 mg/kg bw/day
Step 2: Modification of PoD:
Standard respiratory volume, human (sRVhuman) for 8 hours: 6.7 m3
Standard respiratory volume of the rat (sRVrat) for 8 hours: 0.38 m3/kg bw
Worker respiratory volume (wRV) for 8 hours with light physical activity: 10 m3
Oral absorption of the rat/ inhalation absorption of humans (ABS oral-rat / ABS inh-human): 50%/100 % (default)
Correction for difference between human and experimental exposure conditions: 7 d rat/5 d worker
Corrected NOAEC (inhalation) for workers:
= 100 mg/kg bw/day x 0.5 x 1/0.38 m3/kg bw/day x (6.7 m3/10 m3) x 1.4
= 123.4 mg/m3
Step 3: Overall AF= 50
Intraspecies AF (worker): 5
Interspecies AF, remaining differences: 2.5
Dose response relationship AF: 1
Exposure duration AF: 4
The exposure duration of the OECD TG 422 study performed with the test item was 65 days for females and 34 days for males. In comparison to a subacute 28-day study the OECD TG 422 study provides additional information on fertility and reproduction of the parental generation and furthermore information on developmental toxicity of the offspring. Together with the longer exposure duration (65 days) for females an Assessment factor of 4 is justified.
Whole database AF: 1
The OECD TG 422 toxicity study was conducted according to regulatory standards and was adequately reported. On this basis the quality of the database is not considered to contribute uncertainty and it is therefore not necessary to apply an additional factor.
In conclusion, long term systemic inhalation DNEL, workers = 2.5 mg/m3
Acute, systemic DNEL- exposure via inhalation (workers)
Due to the extremely low vapor pressure (< 1 Pa) of the substance, inhalation exposure is not considered as relevant. Furthermore, no acute oral or dermal toxicity was reported for the substance. Therefore, no DNEL was derived for acute inhalation exposure. The long-term systemic inhalation DNEL will be protective also for acute inhalation exposure.
Long term & acute, local DNEL- exposure via inhalation (workers)
The substance is classified for serious eye irritation and in conclusion local mucosal membrane damage of the respiratory membranes might be possible (in accordance with "Guidance on information requirements and chemical safety assessment, chapter R8"). Furthermore, the substance is classified for skin sensitization and therefore respiration sensitization might be possible. However, due to the extremely low vapor pressure (calculation with EPI Suite 1.57xE-7 Pa) of the substance, inhalation exposure is not considered as relevant and the potential for local respiratory irritation or sensitization is expected to be low. Therefore, no DNEL was derived.
Dermal
Long term, systemic DNEL- exposure via dermal route (workers)
No repeated dose dermal toxicity study with the target substance is available. Therefore, it will be necessary to obtain a long-term dermal DNEL by route-to-route extrapolation.
The NOAEL of 100 mg/kg bw/day derived from an OECD TG 422 study performed with the target was used as the PoD.
Step 1: PoD: NOAEL = 100 mg/kg bw/day
Step 2: Modification into a correct starting point:
Oral absorption of the rat/ dermal absorption of humans (ABS oral-rat / ABS derm-human): 100%/100 % (default)
Correction for difference between human and experimental exposure conditions: 7 d rat/5 d worker
Corrected NOAEL (dermal) for workers:
= 100 mg/kg bw/day x 1.4
= 140 mg/kg bw/day
Step 3: Overall AF= 200
Interspecies AF, allometric scaling (rat to human): 4
Interspecies AF, remaining differences: 2.5
Intraspecies AF (worker): 5
Dose-response relationship AF: 1
Exposure duration AF: 4
The exposure duration of the OECD TG 422 study performed with the test item was 65 days for females and 34 days for males. In comparison to a subacute 28-day study the OECD TG 422 study provides additional information on fertility and reproduction of the parental generation and furthermore information on developmental toxicity of the offspring. Together with the longer exposure duration (65 days) for females an Assessment factor of 4 is justified.
In conclusion, long term systemic dermal DNEL, workers = 0.7 mg/kg bw/day
Acute, systemic DNEL- dermal exposure (workers)
According to ECHA Guidance on information requirements and chemical safety, Chapter R.8, Appendix R. 8-8, „a DNEL for acute toxicity should be derived if an acute toxicity hazard (leading to C&L) has been identified. The substance has low acute dermal toxicity with the LD50 of >2000 mg/kg. Therefore, the DNEL is not required. The long-term dermal DNEL will be protective also for acute dermal exposure.
Long term & acute, local DNEL- dermal exposure (workers)
A qualitative approach has to be implemented to deal with the serious eye damage as well as skin sensitization properties of the substance. As a result, a high hazard is derived.
Hazard to the eye-local effects (worker)
The test item is classified for serious eye damage Cat 1 (H318: "Causes serious eye damage") under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776. Thus, a qualitative risk assessment is done and the substance is assigned to the medium hazard band in accordance with ECHA Guidance on information requirements and chemical safety assessment Part E: Risk Characterisation (2016).
