Nitrogen Triggers Extra-Toxic Algal Blooms In Lake Erie
Over the last 20 years, Lake Erie has been heaving up ever-larger blooms of cyanobacteria that are so toxic they shut down Toledo, Ohio’s drinking water system in 2014. Scientists say that a warming climate and farming practices that deliver more soluble phosphorus are driving the blooms, but they can’t explain precisely why certain types of cyanobacteria dominate, and why the blooms sometimes produce toxins and other times don’t.
