Anwendungen & Verwendung

Verwenden

Sodium Aluminum Sulfate is a leavening agent that releases the majority of the gas during baking, and is not used alone but in com- bination with a faster-acting leavening agent such as monocalcium phosphate. this results in a double-acting baking powder. it is almost nonreactive until heat is applied. it is used in baked goods.

OSHA StandardsVacated 1989 OSHA PEL TWA 2 mg/cu m is still enforced in some states. /Aluminum (soluble salts & alkyls, as Al)/

Freisetung ohne BrandExcerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:
EntsorgungsverfahrenAluminum compounds are treated under anhydrous conditions to prevent violent reactions, recover solvent, and form Al compounds suitable for landfill by reaction with anhydrous hydrolysis agent, eg calcium hydroxide. /Aluminum compounds/SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations.
Preventive MeasuresSRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.Work clothing that becomes wet or significantly contaminated should be removed and replaced. /Aluminum (soluble salts and alkyls, as Al)/Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises. /Aluminum (soluble salts and alkyls, as Al)/The worker should immediately wash the skin when it becomes contaminated. /Aluminum (soluble salts and alkyls, as Al)/SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Gesundheitliche AuswirkungenAluminum targets the nervous system and causes decreased nervous system performance and is associated with altered function of the blood-brain barrier. The accumulation of aluminum in the body may cause bone or brain diseases. High levels of aluminum have been linked to Alzheimer's disease. A small percentage of people are allergic to aluminium and experience contact dermatitis, digestive disorders, vomiting or other symptoms upon contact or ingestion of products containing aluminium. (L739, L740)
ExpositionspfadeOral (L739)inhalation (L739)
ToxizitätsübersichtThe main target organs of aluminum are the central nervous system and bone. Aluminum binds with dietary phosphorus and impairs gastrointestinal absorption of phosphorus. The decreased phosphate body burden results in osteomalacia (softening of the bones due to defective bone mineralization) and rickets. Aluminum's neurotoxicity is believed to involve several mechanisms. Changes in cytoskeletal protein functions as a results of altered phosphorylation, proteolysis, transport, and synthesis are believed to be one cause. Aluminum may induce neurobehavioral effects by affecting permeability of the blood-brain barrier, cholinergic activity, signal transduction pathways, lipid peroxidation, and impair neuronal glutamate nitric oxide-cyclic GMP pathway, as well as interfere with metabolism of essential trace elements because of similar coordination chemistries and consequent competitive interactions. It has been suggested that aluminum's interaction with estrogen receptors increases the expression of estrogen-related genes and thereby contributes to the progression of breast cancer (A235), but studies have not been able to establish a clear link between aluminum and increased risk of breast cancer (A15468). Certain aluminum salts induce immune responses by activating inflammasomes. (L739, A235, A236)
Signs and SymptomsInhalating aluminum dust causes coughing and abnormal chest X-rays. A small percentage of people are allergic to aluminium and experience contact dermatitis, digestive disorders, vomiting or other symptoms upon contact or ingestion of products containing aluminium. (L739, L740)
Natural Pollution SourcesOccurs naturally as the mineral mendozite
Carcinogen ClassificationNot listed by IARC. IARC classified aluminum production as carcinogenic to humans (Group 1), but did not implicate aluminum itself as a human carcinogen. (L135) A link between use of aluminum-containing antiperspirants and increased risk of breast cancer has been proposed (A235), but studies have not been able to establish a clear link (A15468).
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Acute Exposure/ ...For anhydrous sodium aluminum lethal oral dose for rabbit is about 2 g/kg.
Evidence for CarcinogenicityA4: Not classifiable as a human carcinogen. /Aluminum metal and insouble compound/
Probable Routes of Human ExposureWORKMEN ... CONTAMINATED WITH ALUM /THROUGH EYES/ ... . /ALUM/Production of aluminum sulfate and aluminum fluoride is associated with exposure to several irritant substances. Such production has been connected with reversible bronchial obstruction or asthma. In an aluminum plant in Sweden, 6 cases of asthma occurred in 1975, and 7 in 1976. The number of exposed workers was 35-40. The levels of aluminum fluoride (personal sampling) were measured during these two years, and the mean concentrations were 3-6 mg/cu m. In 1977, improvements were made at this plant thereby reducing the mean levels of aluminum fluoride to 0.4-1.0 mg/cu m. During the years 1978-1980, only two cases of asthma occurred. /Aluminum sulfate/
