Two decades of study reveals a complex combination of factors causing large cyanobacterial blooms and their toxicity. Government incentives to reduce nutrient pollution from farms have not been enough to solve the problem so far.

Researchers are studying how much of cyanobacterial toxins become airborne. They say breathing in the toxins is much worse than ingesting them.

Harmful algal blooms are forming in some parts of Lake Erie earlier than they typically do.

Annual blooms of toxic cyanobacteria on western Lake Erie shouldn't be quite as bad this year.Scientists from the National Oceanic and Atmospheric…
