Researchers at Oregon State University have developed a new way to monitor the danger associated with algae blooms: “sniffing” the water for gases associated with toxins.
The scientists found that certain combinations of volatile organic compounds released by algae can serve as indicator for microcystin, a toxin produced at varying levels during blooms of cyanobacteria, commonly known as blue-green algae.
Different cyanobacterial species produce different toxins, said OSU’s Kimberly Halsey, who led the study. Most of them cause gastrointestinal illness and acute skin rashes, and they can be deadly. In 2017, more than 30 cattle died after drinking contaminated water at Junipers Reservoir near Lakeview, Oregon, and blooms particularly pose a threat to dogs entering affected lakes.
