11: Toxicological Information

Routes of Entry: Inhalation. Ingestion.

Toxicity to Animals: Acute oral toxicity (LD50): >9000 mg/kg [Rat].

Chronic Effects on Humans:

DEVELOPMENTAL TOXICITY: Classified Reproductive system/toxin/female, Reproductive system/toxin/male [SUSPECTED]. May cause damage to the following organs: the reproductive system, mucous membranes, skin, eyes, Urinary System.

Other Toxic Effects on Humans:

Hazardous in case of skin contact (irritant), of inhalation (lung irritant). Slightly hazardous in case of ingestion.

Special Remarks on Toxicity to Animals: Not available.

Special Remarks on Chronic Effects on Humans:

May affect genetic material (mutagenic). May cause adverse reproductive effects based on animal test data

Special Remarks on other Toxic Effects on Humans:

Acute Potential Health Effects:

Skin: Causes skin irritation, particularly if moisture is present. Symptoms include redness,

itching, and pain

Eyes: Causes eye irritation. Symptoms include redness and pain.

Inhalation: Causes mouth and respiratory tract irritation. Symptoms may include coughing, shortness of breath. It may cause airway constricting in rare instances. Symptoms are usually transient.

Ingestion: May cause irritation to the gastrointestinal tract. Symptoms may include cramping, nausea, vomiting, diarrhea. Ingestion also produces a feeling of dryness and puckering of the mucous membranes of the mouth and throat. It may affect behaviour/central nervous system and cause ataxia and seizures. High blood concentrations

of aluminium may cause aluminium-induced encephalopathy with confusion, lethargy, respiratory depression, cognitive impairment, dysarthria, asterixis, seizure, coma. It may also affect the liver. Individuals with renal failure may more readily accumulate toxic levels of aluminium which can result in encephalopathy and seizures.

Chronic Potential Health Effects: Skin:

Repeated or prolonged skin contact may cause irritation, especially if moisture is present. Ingestion: Repeated or prolonged ingestion may affect metabolism, urinary system, blood (changes in serum composition – e.g. TP, bilirubin, cholesterol), skeletal system, and brain (degenerative changes). High blood concentrations of aluminium may cause aluminium to be deposited in the bones. Accumulation of aluminium in the bone appears to reduce the positive effects of vitamin D and may

prevent calcium deposition into the bones. The prevention of calcium deposition leads to the return of the calcium to the blood.

This may cause bone/skeletal abnormalities, osteomalacia, painful joints. The elevated serum calcium levels in turn inhibit the release of parathyroid hormone by the parathyroid glands.
