Freshwater Science: A Toxin Forecast for Lake Erie’s Harmful Algal BloomsOHSU-CAST-1705Scientists are currently able to accurately forecast the size and approximate location of Lake Erie’s summer harmful algal blooms, but they still have questions about what controls when blooms become toxic, and how to predict which algal toxins the bloom is likely to produce. Dr. Justin Chaffin at Ohio State’s Stone Lab is studying the environmental factors that cause Lake Erie algal blooms to become toxic or remain non-toxic, to provide more guidance to water utilities on when they should plan to treat drinking water for algal toxins. DURATION: 37 mins |
Freshwater Science: Lake Erie Algae in the Depth of WinterOHSU-CAST-1704Although harmful algal blooms happen in the summer, the algae themselves are year-round residents of the water bodies they inhabit – but very little is known about other times in the annual cycle of blooms. For Lake Erie, ice cover and extreme weather conditions in winter and spring prevent regular monitoring and safe sampling. By partnering with the U.S. and Canadian Coast Guards, Dr. Mike McKay at the University of Windsor can take advantage of those ships’ ice-breaking capabilities to sample offshore waters in winter and early spring, before state and federal agencies start their monitoring efforts. DURATION: 42 mins |
Freshwater Science: Using Bacteria to Remove Microcystin from Drinking WaterOHSU-CAST-1703Many Ohio communities draw their drinking water from Lake Erie, so making sure that any harmful algal bloom toxins are removed before the water reaches consumers is essential to maintaining public health. While water treatment plants currently use activated carbon, ozonation, and other methods to treat for algal toxins, Dr. Jason Huntley at The University of Toledo, with previous funding from the Harmful Algal Bloom Research Initiative and current funding from NOAA-PCMHAB is developing new cost-effective, efficient, and safe methods to remove algal toxins from drinking water, using bacteria that naturally break down microcystin toxin into non-toxic component parts. The team was issued a patent on this technology in May 2021. DURATION: 41 mins |

Freshwater Science: Can Walleye See the Bait on the Hook?OHSU-CAST-1701Walleye fishing in Ohio significantly contributes to the state’s $1.9 billion sportfishing industry, but the fish are experiencing significant changes to their environment due to harmful algal blooms. For these visual hunters, those changes affect finding food and mates, and anglers who fish for walleye may have to change their approach to selecting lures. Dr. Suzanne Gray at The Ohio State University is linking walleye vision, murky waters from harmful algal blooms and lure colors to determine the impacts algal blooms can have on visual hunters like walleye and on the success of Lake Erie’s sportfishing industry. |

Freshwater Science: Health Impacts of Algal Toxins in the Context of Chronic IllnessesOHSU-CAST-1685Algal toxins affect the liver, gastrointestinal system and kidneys, and may have a more severe effect in the context of pre-existing conditions. Dr. David Kennedy and Dr. Steven Haller at The University of Toledo, with funding from Ohio Sea Grant and the Harmful Algal Bloom Research Initiative, are examining these effects to help provide new guidelines for safe exposure levels to algal toxins for people with chronic illnesses. They also aim to develop new tests that can measure toxin exposure at very low levels, which can suppress common liver injury markers in some patients, and to create therapies to treat the organ damage caused by algal toxins.

Freshwater Science: Stopping Algal Bloom Toxins at the Kitchen TapOHSU-CAST-1682Harmful algal bloom toxins are a common concern for people living along the Lake Erie shoreline, where drinking water is often drawn from the lake. In addition to removing these toxins during water treatment, Ohioans may have another tool at their disposal: Dr. Glenn Lipscomb’s research, funded by the Harmful Algal Bloom Research Initiative, has shown that reverse osmosis membranes, an essential component of home water purification systems, can remove algal toxins from drinking water. The mechanism by which toxins are removed will be discussed along with tests for commercially available units. DURATION: 37 mins |
Freshwater Science: Removing Algal Toxins from Drinking Water with Activated CarbonOHSU-CAST-1680During harmful algal bloom season, algal toxins can be common in drinking water drawn from Lake Erie. Water treatment plants are well set up to manage this issue for their customers, and often use powdered activated carbon to remove toxins, but they lack data on proper dosage depending on toxin types, toxin concentration and water properties. Dr. John Lenhart, with funding from Ohio Sea Grant and the Harmful Algal Bloom Research Initiative, is developing these guidelines and sharing them with water treatment plant operators along the Lake Erie shoreline to help reduce the cost of safe drinking water.
