ASTM E1850 PDF

1.1 This guide along with Guide E1192 and guidance from the U.S. Environmental Protection Agency (1,2)2 covers the use of resident species in toxicity testing, particularly if site-specific information is desired. For example, in those systems where particular species are considered to be economically or aesthetically important, it might be more appropriate to utilize resident species for testing (3). For this reason, the USEPA allows development of site-specific chemical standards, using resident species, in order to reflect local conditions (1). This guide is designed to guide the selection of resident species for use as test organisms in aquatic and sediment toxicity tests. It presupposes that the user is familiar with the taxonomy of aquatic and benthic species and has some field experience.
