There is need for a short term acute toxicity test for marine zooplankton due to current capability gaps. While holozooplankton methods are readily available for freshwater, there is a substantial capability gap for marine environments; as one example, the Army Corps / US EPA dredging evaluation program may use this method to satisfy the Marine Protection Research and Sanctuaries Act requirement to test marine zooplankton in dredging evaluations. The common tests conducted are for sedentary or benthic bivalves or echinoderms that are not zooplankton (E1563-98e1, E724-98); they have a short-lived planktonic stage. The need here is for an acute marine toxicity test for a species that is planktonic for its entire life cycle and lives in the coastal waters of the United States (i.e., Pseudodiaptomus). Initial methodologies are briefed in a government technical report (Kennedy et al 2016; http://www.dtic.mil/docs/citations/AD1018837).
The title and scope are in draft form and are under development within this ASTM Committee.
