Examinations
- Observations and examinations performed and frequency:
- Weekly control for clinical signs of illness or death, food consumption and body weight
- Sacrifice and pathology:
- Spontaneously died animals were necropsied.After 20 month: All surviving animals were killed by exsanguination under ether anesthesia without prior fasting.Gross findings were observed and the following organs of all mice were weighed:brain, pituitary, heart, lungs, liver, spleen, kidney adrenals and testes.These organs and the eye balls, harderian gland, submandibular gland, thyroid, thymus, trachea, bronchi, pancreas, stomach, small and large intestines, epididymis, prostate, ovaries, uterus, vagina, mammary glands, mesenteric lymph nodes, femoral bone marrow and skin were fixed in 10% neutralized formalin, embedded in paraffin, sectioned and stained with hematoxylin and cosin (HE).
- Statistics:
- Data were analyzed statistically by the students t-test for body weight and organ weights (absolute and relative weight), and X² testfor histopathological examinations.

Applicant's summary and conclusion
- Conclusions:
- The results of the present study indicate that long-term administration of a diet containing 10.0 % aluminium potassium bis sulphate (AlK(SO4)2*12H2O) does not exert tumorgenicity or any other toxic actions in B3C6F1 mice.Slight growth retardation compared with controls at 10% groups after 1 month.Slight increase of body weight at 1 and 2.5% groups after 3 month.Similar growth at 5% groups compared with controls.NOAEL-20 month B3C6F1 male/female mice oral: 10 % aluminium potassium bis sulphate *12H2O (w/w).NOAEL: 853 mg Al/kg bw/d = 8160 mg aluminium potassium bis sulphate/kg bw/d.

Similar growth at 5% groups compared with controls.
NOAEL-20 month B3C6F1 male/female mice oral: 10 % aluminium potassium bis sulphate *12H2O (w/w).
NOAEL: 853 mg Al/kg bw/d = 8160 mg aluminium potassium bis sulphate/kg bw/d.
