Neurotoxin With Possible Ties To Parkinson's Found In Air Samples

Satellite imagery taken June 6, 2022, showed A 100-square-mile bloom of blue-green algae along Lake Okeechobee's northwestern shoreline
Blue-green algae on the Caloosahatchee River on July 2018. Blue green algae is known as cynobacteria and produces a liver toxin.

Researchers from Florida Gulf Coast University have been trying to find how toxic algal blooms would interact with the human respiratory system.

In late November, the group reported the toxic compound microcystin was reaching particle sizes that could reach into human lungs.

Testing kits purchased with the help of the National Oceanic and Atmospheric Administration, revealed that a neurological toxin called BMAA, which is short for beta-Methylamino-L-alanine, was also present in air samples.

FGCU marine science professor Dr. Mike Parsons is a part of the research team and says there is data that shows, but also refutes, a link between BMAA and diseases like Parkinson’s and ALS.   

“So it still is a questionable link between BMAA and these degenerative neurological diseases so it does require more work,” Parsons said. 

Parsons also said BMAA was present in samples of nasal, blood and urine taken by the Florida Atlantic University’s Harbor Branch Oceanographic Institute earlier in the fall.

“People are being exposed to it," Parsons said. "Is it a real threat or not? And that’s what we are not sure about.”

Parsons said much more research needs to be done before determining whether or not the neurotoxin can be labeled as a threat to humans. He hopes to collaborate with other institutions and health organizations in the future.
