New Guide for Standard Guide(Method) for Conducting Acute Water Column Toxicity Bioassays using Marine Calanoid Copepods

1. Scope

The promotion of knowledge, stimulation of research, and development of standard guides, specifications, practices, test methods, classifications, and definitions relating to environmental assessment, risk management and corrective action. The scope of the Committee includes, but is not limited to multi-media environmental assessment and risk management issues including environmental assessment, environmental management, corrective action due diligence, and sustainability.
These activities will be coordinated with and if available use the standards of other ASTM technical committees and organizations whose fields of endeavor are closely allied to or compliment environmental assessment and environmental management.

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;

The title and scope are in draft form and are under development within this ASTM Committee.
