Additional information
Inhalation exposure
The toxicological literature for subchronic and chronic inhalation exposure studies is limited. Report on several studies of durations of six months (six hours a day, five days a week). The most sensitive and best documented endpoints concerned the respiratory system. The observed effects are those commonly associated with particle inhalation exposure (> 600 μg/m3),(Stone et al.1979) including a thickening of the alveolar walls, and an increase in alveolar macrophages, granulomatous lesions and relative lung weight (ATSDR2006).
No studies were located regarding repeated dose toxicity effects in animals after dermal exposure to various forms of aluminium.
For dermal exposure we taken that:
-the average weight of rats is 250g (200-300g),
-the dose is applied over an area which is approximately 10% of the total body surface=0.025 kg
corrected dermal LOAEL= oral LOAEL
544 mg/kg bw/day 0.025 kg =
LOAELrat 13.6 mg/kg bw/day
Inhalation exposure:
The oral dose for the rat is converted to the corresponding air concentration using a standard breathing volume for the rat (1.15 m3/kg for 24 hours exposure. The resulting air concentration needs to be additionally corrected for 24 hlight activity (20 m3), assuming 100 % absorption for both routes.

Repeated dose toxicity: via oral route - systemic effects (target organ) neurologic: behaviour; neurologic: brain (multiple sections); other: all gross lesions and masses
Repeated dose toxicity: inhalation - systemic effects (target organ) cardiovascular / hematological: lymph nodes; respiratory: lung
Repeated dose toxicity: dermal - systemic effects (target organ) digestive: liver; digestive: stomach; neurologic: behaviour; neurologic: brain (multiple sections); urogenital: kidneys
Justification for classification or non-classification
Based on the hazard assessment of aluminium sulphate in section 2.1 and 2.2.in IUCLID 5.2., available data for the substance and following the “Guidance on Information Requirement and Chemical Safety Assessment R.8. Characterisation of dose [concentration]- response for human health” andaccording to the criteria described in Directive 67/548 and in the CLP Regulation:

Repeated dose toxicity STOT Rep. Exp. 1 STOT Rep. Exp. 2 H372: Causes damage to organs <or state all organs affected, if known> through prolonged or repeated exposure <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. H373: May cause damage to organs <or state all organs affected, if known> through prolonged or repeated exposure <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
It is concluded that the substance aluminium sulphate does not meet the criteria to be classified for human health hazards for Repeated dose toxicity
