Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
3.93 mg/m³
Most sensitive endpoint:
developmental toxicity / teratogenicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
75
Modified dose descriptor starting point:
NOAEC
Value:
292.775 mg/m³
Explanation for the modification of the dose descriptor starting point:

Inhalation is not the preferred route for absorption. Original value is NOAEL 239 mg/kg bw/day from reproductive/developmental toxicity study on rat by oral administration performed on similar substance and recalculated on target substance (for details regarding read-across justification and derivation of NOAEL see attached document in section 13 of this IUCLID dossier ). Allometric scaling from rat to human is 4. The result is multiplied by 70 kg considered as the average weight of a human being (bw) and divided by 10 m^3/person considered as the average volume that is breathed in a 8h exposure. Conclusion [(239 mg/kg bw/d / 4)*70 kg bw]/10 m^3/person= 418.25 mg/m^3. This value should be multiply by 0.5 (considering the oral absorption 50% in oral-to-inhalation extrapolation) and by 1.4 (considering the correction for differences between human and experimental exposure conditions, i.e. 7 days per week (experimental)/ 5 days per week (worker population)). NAEC is 292.775 mg/ m^3.

low hazard (no threshold derived)

Additional information - workers

Tris(ethyl acetoacetato-O1',O3)aluminium is classified H317 (skin sens. cat.1) and H319 (eye irr.cat.2) according to the CLP Regulation (EC n.1272/2008).

The assessment is done based on reproduction/developmental toxicity study on rats by oral route for a similar substance. The NOAEL from this study was modified considering the structure and the molecular weight of Tris(ethyl acetoacetato-O1',O3)aluminium and NOAEL obtained for target substance = 239 mg/kg bw/day (for details regarding read-across justification and derivation of NOAEL see attached document in section 13 of this IUCLID dossier )

 

The values of DNEL calculated for workers are:

 

INHALATION ROUTE:

SYSTEMIC EFFECTS:

a) LONG TERM: DNEL= 3.93 mg/m^3 (NAEC= 292.775 mg/m^3 and Overall AF= 75)

b) SHORT TERM: No hazard identified

LOCAL EFFECTS: Low hazard identified for LONG and SHORT TERM exposure based on its potential to be irritant for mucous membrane of nasopharyngeal region.

 

DERMAL ROUTE:

SYSTEMIC EFFECTS:

a) LONG TERM: DNEL = 1.12 mg/kg bw/day (Starting point: 239 mg/kg bw/day (NOAEL for target substance) *1.4 = 334.6 mg/kg bw/day and Overall AF= 300)

b) SHORT TERM: High hazard identified due to classification H317 (skin sens. cat.1)

LOCAL EFFECTS: No hazard identified for LONG AND SHORT TERM based on the substance is not skin irritant and there is no reason of concern for acute dermal toxicity.

HAZARD FOR EYE:LOCAL EFFECTS: Low hazard identified based on the substance is classified irritant to the eyes (H319).
