Debido a que el aluminio es tan común y se encuentra ampliamente distribuido en el ambiente, es imposible evitar la exposición a esta sustancia.
Evite el consumo de cantidades altas de productos que contienen aluminio tales como antiácidos o aspirina con cubierta entérica. Siempre use estos productos de acuerdo a las instrucciones.
Asegúrese de que todos lo medicamentos tengan tapas a prueba de niños de manera que los niños no puedan ingerirlos accidentalmente.

El aluminio se encuentra en virtualmente todos los alimentos, el agua, el aire y el suelo.
Un adulto promedio en EE. UU. ingiere aproximadamente 7 a 9 miligramos (mg) de aluminio al día en los alimentos.
Respirando niveles altos de aluminio en polvo en el aire del trabajo.
Viviendo en áreas donde el aire contiene polvo, donde el aluminio se mina o procesa a aluminio metálico, cerca de algunos sitios de desechos peligrosos o donde hay niveles naturalmente altos de aluminio.
Ingiriendo sustancias que contienen niveles altos de aluminio (por ejemplo antiácidos), especialmente cuando se ingieren bebidas cítricas al mismo tiempo.
Los niños y los adultos pueden exponerse a pequeñas cantidades de aluminio en vacunas.
Muy poco aluminio entra al cuerpo al usar utensilios de cocina de aluminio.

El aluminio es el metal más abundante en la corteza terrestre. Siempre se encuentra combinado con otros elementos tales como oxígeno, sílice y flúor. El aluminio metálico se obtiene de minerales que contienen aluminio. Se pueden encontrar pequeñas cantidades de aluminio disueltas en el agua.
El aluminio metálico es liviano y de color blanco-plateado. El aluminio se usa en envases de bebidas, ollas y sartenes, aviones, techos y cubiertas exteriores de viviendas y en láminas de aluminio. A menudo se mezcla con pequeñas cantidades de otros metales para formar aleaciones, las cuales son más duras y resistentes.
Los compuestos de aluminio tienen muchos usos diferentes, por ejemplo, el alumbre se usa en el tratamiento de aguas y la alúmina en abrasivos y revestimientos de hornos. También se encuentran en productos de consumo tales como antiácidos, astringentes, aspirina con cubierta entérica, aditivos para alimentos, cosméticos y desodorantes.

| What is Aluminium sulphate used for? |

Aluminum sulfate has many different uses in day-to-day life, as well as being used in several essential industries. In fact, you probably come into contact with it on a daily basis without even knowing it!
Household Uses
Some of the most common uses of aluminum sulfate are found within the home. The compound is often found in baking soda, although there’s some controversy over whether it’s appropriate to add aluminum to the diet. Some antiperspirants contain aluminum sulfate because of its antibacterial properties, although as of 2005 the FDA does not recognize it as a wetness reducer. Finally, the compound is the astringent ingredient in styptic pencils, which are designed to stop small cuts from bleeding.
Gardening
Other interesting uses of aluminum sulfate around the house are in gardening. Because aluminum sulfate is extremely acidic, it’s sometimes added to very alkaline soils to balance the pH for plants. When the aluminum sulfate comes into contact with water, it forms aluminum hydroxide and a much diluted sulfuric acid solution, which alters the soil acidity. Gardeners who plant hydrangeas apply this property to change the flower color (blue or pink) of the hydrangeas since this plant is very sensitive to soil pH.
Aluminum SulfateWater Treatment
One of the most important uses of aluminum sulfate is in water treatment and purification. When added to water, it causes microscopic impurities to clump together into larger and larger particles. These clumps of impurities will then settle to the bottom of the container or at least get large enough to filter them out of the water. This makes the water safer to drink. On the same principle, aluminum sulfate is also sometimes used in swimming pools to decrease the cloudiness of the water.
Dyeing Fabrics
Another one of the many uses of aluminum sulfate is in dyeing and printing on cloth. When dissolved in a large amount of water that has a neutral or slightly alkaline pH, the compound produces a gooey substance, aluminum hydroxide. The gooey substance helps dyes stick to the cloth fibers by making the dye water insoluble. The role of aluminum sulfate, then, is as a dye “fixer,” which means that it combines with the molecular structure of the dye and the fabric so the dye doesn’t run out when the fabric gets wet.
Paper Making
In the past, aluminum sulfate was used in making paper, although synthetic agents have mostly replaced it. The aluminum sulfate helped to size of the paper. In this process, aluminum sulfate was combined with rosin soap to change the absorbency of the paper. This changes the ink-absorbing properties of the paper. Using aluminum sulfate means that the paper was made under acidic conditions. Use of synthetic sizing agents means that acid-free paper can be produced. Acid-free paper does not break down as fast as paper sized with acid.
Though you may not have known it, aluminum sulfate is used to make many products you use daily. Even the water you drink is filtered using aluminum sulfate!

Aluminum hydroxide is a medication used in the management and treatment of acid indigestion. It is in the antacid class of drugs.
Aluminum hydroxide is often administered orally for the temporary relief of heartburn or gastroesophageal reflux. It may be used topically, temporarily, to protect and relieve chafed and abraded skin, minor wounds and burns, and skin irritations resulting from friction and rubbing. Patients may also receive it to treat chemo-induced oral mucositis in the form of a mouthwash.Additionally, it is approved for use as an adjuvant in numerous vaccines due to its ability to increase phagocytosis and spur immune responses.[3] It also has approval for use in a wide array of cosmetic products at varying concentrations.[4] Aluminum hydroxide can also serve as a phosphate binder in patients with chronic renal disease. However, its use in this manner is infrequent due to the risk of adverse effects. Commonly, oral aluminum hydroxide is a liquid formulation of both aluminum and magnesium hydroxide

aluminum bronze, any of a group of strong, corrosion-resistant alloys of copper containing from 4 to 15 percent aluminum and small amounts of other metals, used to make many machine parts and tools. Because of their golden colour and high tarnish resistance, the alloys are also used for jewelry and in architecture.

| What should I use instead of aluminum as an oven liner? |

If you can’t use aluminum foil in the bottom of your oven, what should you use instead? If you want to avoid cleaning up caked-on drips and spills, there are a few things you can do:
Put an empty baking dish on the rack below the food you are cooking. It will catch drips and make clean-up easier.
Use a silicone oven liner on your cooking racks. These heat-resistant, non-reflective accessories will help you keep your oven clean without interfering with cook times. Be aware that oven liners are only suitable for electric or convection ovens and should never be placed on the bottom of the oven. You should not use oven liners in gas ovens, microwaves or countertop microwave ovens.
If you’re looking for alternatives to using aluminum foil on baking sheets, consider parchment paper. It is non-reflective and won’t scratch non-stick surfaces.
Before using parchment paper, it is important to review the manufacturer’s recommendation for max parchment bake temperatures. Generally speaking, parchment paper should never touch the sides of your oven or be used for intense radiant cooking functions over 450 degrees (i.e. broiling). Additionally, do not use parchment paper in gas ovens with an exposed flame.
If you’ve used aluminum foil in your oven in the past, you may want to make sure it didn’t affect the heating elements. Take some time to calibrate your oven, and schedule service if you think something is amiss.

If you’re lining baking sheets, wrapping up food or covering it up to retain moisture, then aluminum foil is the way to go. It’s versatile and resistant to heat, making it a great option for cooking and baking. But when it comes to protecting your oven from spills, it’s best to keep your foil in the box. While people may recommend using aluminum foil in the oven along the bottom or the racks, doing so can actually have serious consequences. That’s because while foil is heat resistant, it isn’t completely heat-proof. Using high heat with aluminum foil in the oven bottom could cause the foil to melt, permanently damaging your appliance. Using aluminum foil as an oven liner can also cause the following issues:
![[Image: 3-1.jpg]](http://aluminium-foils-cn.com/images/pic/3-1.jpg)
Using foil on oven racks can disrupt heat distribution in the oven and interfere with optimal cooking results.
Covering up vent openings in the bottom of the oven can lead to insufficient air flow, heat distribution and issues with performance.
Heat reflecting off aluminum foil can overcook foods or damage your oven’s heating elements.
Lining your gas oven with aluminum foil can block heat, air flow, and produce less than optimal cooking results.
