| Study Purpose | Cyanobacteria (blue-green algae or “toxic” algae) are common in many inland waters worldwide. This diverse group of algae has different life histories and habitat niches, however the most widely recognized are the planktonic (open water) species capable of producing toxins (collectively cyanotoxins) that are harmful to humans and wildlife. Studies by Ecology and others have also shown that cyanotoxins can accumulate in the deeper sediments of lakes. Little is known about the accumulation of cyanotoxins in the nearshore sediments of lakes. The goals of this study are to: (1) determine the prevalence and persistence of cyanotoxins (microcystin variants) in littoral (shoreline) sediments and porewaters of lakes in the Puget Sound region, and (2) determine the historic prevalence of cyanobacteria in Anderson Lake, Jefferson County using a sediment core representing the last ~150 years. |
