Fuller LM, Brennan AK, Fogarty LR, Loftin KA, Johnson HE, VanderMeulen DD, Lafrancois BM. 2017. Detection of Microcystin and Other Cyanotoxins in Lakes at Isle Royale National Park, Pictured Rocks National Lakeshore, and Sleeping Bear Dunes Lakeshore, Northern Michigan, 2012–13. U.S. Geological Survey (USGS) Scientific Investigations Report. Scientific Investigations Report 2017–5122. USGS. Reston, VA
The purpose of this report is to describe the detection of microcystin and other algal toxins in several inland lakes in ISRO, PIRO, and SLBE. The objectives of this report are to (1)highlight previous studies that have evaluated cyanotoxinswithin the study area, (2) describe detections of cyanotoxins inlake samples by use of enzyme-linked immunosorbent assays(ELISA) (Abraxis, LLC) and liquid chromatography/tandemmass spectrometry (LC/MS/MS) methods, (3) compare ELISA microcystin results to the WHO recreational guideline for acute health effects (less than 10 μg/L; World Health Organization, 2003a) and to the EPA drinking-water recommendations (U.S. Environmental Protection Agency, 2015b) to provide a context for potential human-health risk, (4) evaluate results to determine if microcystin concentrations differed by lake and if concentrations differed seasonally, and (5) relate cyanotoxin results to nutrient ratios within each lake.
