Aluminum is an endocrine disruptor. It may affect the function of the reproductive system, along with the lungs, the bones and the immune system.
Discussed below are the impacts on fertility and pregnancy, where aluminum could be present in the home, and how to mitigate exposure:
What is aluminum? Aluminum is a malleable, lightweight, nonferrous metal and it is the most abundant metallic element on the Earth’s crust. It is mined from Bauxite (a mixture of aluminum oxides) as the principal aluminum ore for use in construction. Aluminum powder is white to grey in color and it is soft in its pure form. For construction applications, aluminum gets mixed with silicon and iron. This transforms it into a strong, ductile and malleable material that can be used in a wire or sheet form. It is very corrosion resistant and suitable for interior as well as exterior applications.
How does aluminum impact fertility and pregnancy? Generally, aluminum is an endocrine disruptor. It can affect the function of the reproductive system, as well as the lungs, the bones and the immune system. Aluminum causes oxidative stress in the blood. When it comes to fertility, this can lead to reduced levels of FSH and LH hormone in women and testosterone in men. Significant decline in sperm count and higher sperm DNA fragmentation have been linked to elevated aluminum in the blood. High content of aluminum in the mother’s body could impair the growth and development of the fetus during pregnancy. Aluminum can also be passed through breast milk after birth and stored in the baby’s body.
Where could aluminum be present in the home and how to mitigate exposure? 1. Roofing, flashing, siding Aluminum is most frequently used for exterior applications as a roofing, flashing and siding material. Aluminum leaching in the soil could be absorbed by plants in the vicinity elevating their toxicity. If gardening, in particular growing fruits or vegetables for consumption, it is best to avoid planning them near aluminum sheets. A better material to use for roofing and flashing is copper, which our bodies need for production of red blood cells to keep our cells, immune system and boned healthy. As a siding material, if the local climate allows, unfinished wood species, such as cedar, are far superior to other materials. Wood is a natural material and a healthy option for people.
2. Paint Some paints contain aluminum, which make them more durable in high temperatures and corrosion resistant. Contact with aluminum could lead to skin rashes and allergies. Better choice for paints is to use mineral ones or plant-based paints.
3. Wiring Electrical wiring and conductors, and electronics may contain aluminum. Aluminum is cheaper than copper has been used in wiring for this reason. Copper is superior wiring and preferrable for use in the home. If discarding of old wiring and electronics it is best bring them to the appropriate recycling centers as to not let the aluminum leach in the soil in the landfill.
4. Others Other items in the home containing aluminum are cookware, baking and packaging of foods, such as cans and aluminum foil. Those can leach aluminum in the food turning it toxic for the body, and particularly having adverse effects in small children. These products are best to be avoided altogether. Instead, using stainless steel and cast-iron cookware, and glass containers are significantly healthier choices.
The main takeaway is that aluminum is highly toxic and an endocrine disruptor capable of rendering both women and men infertile. It is best advised we steer clear of aluminum when trying to conceive.
