Keith A. Loftin Andrew C. Ziegler Michael T. Meyer Jennifer L. Graham 2008 Cyanobacteria and associated toxins and taste-and-odor compounds are of increasing environmental concern. However, consistent guidelines for the development of studies assessing cyanobacterial toxins and taste-and-odor compounds presently are not available. This report provides guidance for the development of scientific studies of cyanobacteria and associated by-products in lakes and reservoirs. Topics include: background information on cyanobacteria, toxins, and taste-and-odor compounds; spatial and temporal considerations that are unique to the cyanobacteria in lakes and reservoirs; common study types, objectives, and approaches for studies of cyanobacteria and associated toxins and taste-and-odor compounds; general guidelines for collecting samples; and information on sample handling, preparation, processing, and shipping. application/pdf 10.3133/sir20085038 en U.S. Geological Survey Guidelines for design and sampling for cyanobacterial toxin and taste-and-odor studies in lakes and reservoirs reports
