Abstract

The study of cyanobacteria and associated toxins and taste-and-odor compounds is an active area of research. Cyanobacteria and the compounds they produce are receiving increased attention as an economic, environmental, and human health issue. Consistent guidelines and sampling protocols are needed for the development of scientific studies of cyanobacterial toxins and taste-and-odor compounds in order to produce nationally comparable data sets that will allow for scientifically based evaluation and interpretation among a spectrum of studies in various areas. NFM 7.5 provides background information on cyanobacteria and study designs and objectives related to the occurrence of cyanobacterial populations in lakes and reservoirs, and describes standard USGS procedures for collecting, processing, and handling samples to be analyzed for cyanobacterial community composition (enumeration and identification) and total, particulate, and dissolved cyanobacterial toxins and taste-and-odor compounds.
