Title
Standard Guide for Conducting Static and Flow-Through Acute Toxicity Tests with Mysids From the West Coast of the United States
ASTM International
Publication Date:
Feb 15, 1992
Scope:
This guide describes procedures for obtaining data concerning the
adverse effects of a test
material (not food) added to marine and estuarine waters on certain
species of marine and estuarine
mysids during 96 h of continuous exposure. Juvenile mysids used in
these tests are taken from
cultures shortly after release from the brood and exposed to varying
concentrations of a toxicant
in static or flow-through conditions. These procedures will be useful
for conducting toxicity tests
with other species of mysids, although modifications might be
necessary.
Modifications of these procedures might be justified by special needs
or circumstances. Although
using appropriate procedures is more important than following
prescribed procedures, results of
tests conducted using unusual procedures are not likely to be
comparable to results of many other
tests. Comparisons of results obtained using modified and unmodified
versions of these procedures
might provide useful information concerning new concepts and
procedures for conducting acute tests
with other species of mysids.
The procedures given in this guide are applicable to most chemicals,
either individually or in
formulations, commercial products, and known or unknown mixtures. With
appropriate modifications
these procedures can be used to conduct acute tests on factors such as
temperature, salinity, and
dissolved oxygen. These procedures can also be used to assess the
toxicity of potentially toxic
discharges such as municipal wastes, oil drilling fluids, produced
water from oil well production,
and other types of industrial wastes.
Results of acute toxicity tests with toxicants experimentally added to
salt and estuarine waters
should usually be reported in terms of a LC50 (median lethal
concentration).
This guide is arranged as follows:
The values stated in SI units are to be regarded as the standard.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use. Specific
precautionary statements are given in Section 7.
