    _ _ 6-6- What impact
    There are environmental impacts associated with each stage of aluminum production, from extraction to processing. The major environmental impact of refining and smelting is greenhouse gas emissions. These gases result from both the electrical consumption of smelters and the byproducts of processing. The greenhouse gases resulting from primary production include per fluorocarbons (PFC), polycyclic aromatic hydrocarbon (PAH), fluoride, sulfur dioxide (S02), and carbon dioxide (CO2). Of these gases, PFC's resulting from the smelting process are the most potent. Primary aluminum production is the leading source of per-fluorocarbon emissions in the United States. PAH emissions result from the manufacture of anodes for smelters and during the electrolytic process. Sulfur dioxide and sodium fluoride are emitted from smelters and electrical plants. SO2 is one of the primary precursors of acid rain. CO2 emissions occur during smelting and result from the consumption of carbon anodes and from PFC emissions.
    The atmospheric pollutants from primary aluminum production also produce acid rain when they mix with water vapor. Aluminum poses no danger of environmental toxicity when soil pH remains at or above 5.0, however acid rain lowers the pH of soil and forces aluminum into solution. This causes it to leach into the water supply where it can damage root systems and create acidified lakes. Due to its natural abundance, the amount of aluminum that enters the environment due to regular weather processes far exceeds anthropogenic contributions.
    Large amounts of aluminum can be toxic to humans, but high exposure levels are typically limited to miners, aluminum production workers, and dialysis patients. While there is some evidence linking aluminum to Alzheimer's disease, increased aluminum intake has yet to be a proven cause of the onset of Alzheimer's. Otherwise, aluminum is not significantly bioaccumulated in plants and animals.
