ALUMINUM COMPOUNDS: HUMAN TOXICITY

Prolonged exposure to aluminum can cause systemic toxicity, mainly affecting the gastrointestinal tract and causing neurological and skeletal effects. The production of aluminum-associated bone disease can be accelerated with the simultaneous ingestion of aluminum... Neurological effects, including impairment of cognitive function and motor dysfunction, have also been associated with occupational exposure to aluminum in the workplace air... Aluminum is a potent neurotoxic agent in humans. The association between aluminum and characteristics of Alzheimer's disease have prompted numerous studies of all sources of intake of aluminum...
