Human exposure to cyanobacteria and BMAA

摘要

Cyanobacteria are found worldwide, primarily in aquatic habitats. They are increasing in abundance as a result of increas-ing nutrient inputs from various human activities. Recent data indicate that most cyanobacteria produce the neurotoxinbeta-N-methylamino-L-alanine (BMAA), and this toxin can biomagnify UP some food chains to rather high concentrationsin animals used as food by humans. BMAA may pose an increasing human health risk.
