Standard Guide for Conducting Sediment Toxicity Tests with Polychaetous Annelids
< div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.1< / span> This guide covers procedures for obtaining laboratory data concerning the adverse effects of potentially contaminated sediment, or of a test material added experimentally to contaminated or uncontaminated sediment, on marine or estuarine infaunal polychaetes during 10-day or 20 to 28-day exposures. These procedures are useful for testing the effects of various geochemical characteristics of sediments on marine and estuarine polychaetes and could be used to assess sediment toxicity to other infaunal taxa, although modifications of the procedures appropriate to the test species might be necessary. Procedures for the 10-day static test are described for < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > Neanthes arenaceodentata < / span> and < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > Alitta virens < / span> < span style=" font-style:normal " > < span class=" footnote-link" > 2< / span> < / span> (formerly < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > Nereis virens< / span> and < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > Neanthes virens< / span> ) and for the 20 to 28-day static-renewal sediment toxicity for < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > N. arenaceodentata< / span> .
