In the battle against harmful algal blooms (HABs), time is important . The need for laboratory equipment and testing is a serious challenge for water managers. This issue caught the eye of Qingshan Wei , an assistant professor of chemical and biomolecular engineering at North Carolina State University .
“Our research group is interested in developing low-cost sensors,” Wei told EM . “Recently we have been developing sensors for environmental monitoring, and cyanotoxins came to our attention .”
Cyanobacteria, which generate HABs, are becoming a challenge across the US . They are a very serious problem in North Carolina, in part due to the weather.Read More
New research from scientists at the Environmental Working Group (EWG) shows that an approach that assesses cumulative risk from water contaminants could save lives. EWG senior scientist Tasha Stoiber spoke with EM about how the team developed the innovative new approach .
“Our organization has worked extensively on tap water over the years, and an updated version of our tap water database was just released in 2017,” explains Dr. Stoiber. “We've been thinking about new ways to analyze that data.”
Right now, the risk from contaminants in water quality is assessed one at a time—but that really doesn't comport with reality.Read More
Washington Department of Fish and Wildlife (WDFW ) scientists are using a customized underwater robotic vehicle (remotely operated vehicle or ROV) called the Saab Seaeye Falcon on a critical conservation study of threatened and imperiled rockfish. Dr. Dayv Lowry , a Senior Marine Fish Research Scientist, spoke to EM about using the ROV to facilitate rockfish conservation and recovery in the Puget Sound.
“In the Pacific Northwest, the Washington and Oregon coast, several species of Rockfish have been fished for decades, with up- and downswings in abundance,” explains Dr. Lowry. “When fishing pressure decreases, and the stocks start to recover, we have gone back to fishing—the pendulum has swung over the years.Read More
