Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Workers - Hazard via inhalation route

Systemic effects

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

Inhalation should not be a preferred route for absorption. Original value is NOAEL 35.2 mg/kg bw, subacute toxicity in rat by oral administration. 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 10m3/person considered as the average volume that is breathed in a 8h exposure. Conclusion [(35.2 mg/Kg / 4)*70 Kg bw]/10 m3/person= 61.6 mg/m3 bw

Additional information - workers

Aluminium hypophosphite is not classified regarding human toxicity.

The assessment is done based on repeated dose toxicity studies (NOAEL 28 days rat = 35.2 mg/kg/bw).

 

The values of DNEL calculated for workers are:

 

INHALATION ROUTE:

SYSTEMIC EFFECTS:

a) LONG TERM: DNEL= 0.821 mg/m^3 (NAEC= 61.6 mg/m^3 and Overall AF= 75)

b) SHORT TERM: No hazard identified

LOCAL EFFECTS: No hazard identified for LONG AND SHORT TERM

 

DERMAL ROUTE:

SYSTEMIC EFFECTS:

a) LONG TERM: DNEL = 1.173 mg/kg/bw day (Modified starting point= 352 mg/kg/bw day and Overall AF= 300)

b) SHORT TERM: No hazard identified

LOCAL EFFECTS: No hazard identified FOR LONG AND SHORT TERM

 

HAZARD FOR EYE: LOCAL EFFECTS: no hazard identified

General Population - Hazard via inhalation route

Explanation for the modification of the dose descriptor starting point:

Inhalation should not be a preferred route for absorption. Original value is NOAEL 35.2 mg/kg bw, subacute toxicity in rat by oral administration. 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 20 m3/person considered as the average volume that is breathed by general population. Conclusion [(35.2 mg/kg / 4)*70 kg bw]/20 = 30.8 mg/m3 bw
