ABSTRACT

Chronic inhalation of aerosolized β-N-methylamino-L-alanine (BMAA) could serve as potenital route for exposure to this cyanobacterial neurotoxin implicated in the development of neurodegenerative disease. We investigated environmental aerosol BMAA loads and the fate of inhaled isotopically labeled aerosolized BMAA in adult male Sprague Dawley rats, with doses corresponding to chronic aerosolized environmental BMAA exposure of over 65 days and up to 266 years. Environmental BMAA aerosol concentrations ranged from 6-39 pg L¯
