Effects Of Aluminium On The Enviroment???

Answer 1

No sure how much info that you need.

Please read the following summary:

"11.1.1 Healthy general population

Hazards posed by aluminium to intrauterine and neurological
development and brain function have been identified through animal
studies. However, aluminium has not been shown to pose a health risk
to healthy, non-occupationally exposed humans.

There is no evidence to support a primary causative role of
aluminium in Alzheimer's disease (AD). Aluminium does not induce AD
pathology in vivo in any species, including humans.

The hypothesis that exposure of the elderly population in some
regions to high levels of aluminium in drinking-water may exacerbate
or accelerate AD is not supported by available data.

It has also been hypothesized that particular exposures, either
occupational or via drinking-water, may be associated with non-
specific impaired cognitive function. The data in support of this
hypothesis are currently inadequate.

There is insufficient health-related evidence to justify
revisions to existing WHO Guidelines for aluminium exposure in
healthy, non-occupationally exposed humans. As an example, there is an
inadequate scientific basis for setting a health-based standard for
aluminium in drinking-water.

11.1.2 Subpopulations at special risk

In people of all ages with impaired renal function, aluminium
accumulation has been shown to cause the clinical syndrome of
encephalopathy, vitamin-D-resistant osteomalacia and microcytic
anaemia. The sources of aluminium are haemodialysis fluid and
aluminium-containing pharmaceutical agents (e.g., phosphate binders).
Intestinal absorption can be exacerbated by the use of citrate-
containing products. Patients with renal failure are thus at risk of
neurotoxicity from aluminium.

Iatrogenic aluminium exposure poses a hazard to patients with
chronic renal failure and to premature infants. Every effort should be
made to limit such exposure in these groups.

11.1.3 Occupationally exposed populations

Workers having long-term, high-level exposure to fine aluminium
particulates may be at increased risk of adverse health effects.
However, there are insufficient data from which to develop, with any
degree of certainty, occupational exposure limits with regards to the
adverse effects of aluminium.

Exposure to stamped pyrotechnic aluminium powder, usually
coated with mineral oil lubricants, has caused pulmonary fibrosis
(aluminosis), whereas exposure to other forms of aluminium has not
been proved to cause pulmonary fibrosis. Most reported cases involved
exposure to other potentially fibrogenic agents.

Irritant-induced asthma has been shown to be associated with
inhalation of aluminium sulfate, aluminium fluoride and potassium
aluminium tetrafluoride, and found to occur within the complex
environment of primary aluminium production, especially in potrooms.

11.1.4 Environmental risk

Aluminium-bearing solid phases in the environment are relatively
insoluble, particularly at circumneutral pH values, resulting in low
concentrations of dissolved aluminium in most natural waters.

In acidic or poorly buffered environments subjected to strong
acidifying inputs, concentrations of aluminium can increase to levels
resulting in adverse effects on both aquatic organisms and terrestrial
plants. However, there exist large species, strain and life-history
stage differences in sensitivity to this metal.

The detrimental biological effects from elevated concentrations
of inorganic monomeric aluminium can be mitigated in the presence of
organic acids, fluorides, silicate and high levels of calcium and
magnesium.

A substantial reduction in species richness is associated with
the mobilization of the more toxic forms of aluminium in acid-stressed
waters. This loss of species diversity is reflected at all trophic
levels.

Answer 2

Aluminum itself isn't that bad for the environment. not corrosive and recyclable. Almost ideal.

Getting the ore and processing it to that product however is very stressful for the environment.
