Abstract

The effects of sediment storage time were determined for three sediment toxicity tests: the amphipod test using Rhepoxynius abronius, the polychaete test using Neanthes sp., and the Microtox{reg_sign} test using Photobacterium phosphoreum. Sediments were collected from a reference area and a contaminated area in Puget Sound to determine the effects of storage time on each type of sediment. Toxicity comparisons were also made between the two kinds of sediment to simulate the manner in which the data might be analyzed in a regulatory or decision-making context. Sediments were stored at 4 C for as long as 16 weeks. Results of all three toxicity tests varied significantly with storage time for each type of sediment. Amphipod survival generally decreased with storage time, whereas luminescence in the Microtox test and polychaete biomass varied unpredictably. The significance of differences between results for the two sediments varied unpredictably with storage time for the amphipod and Microtox tests. By contrast, differences were consistently significant for all storage times for the polychaete test, primarily because of the large differences in the test response between sediments. These results suggest that effects of storage time are greater for results indicative of low to intermediate levels of toxicity thanmore »« less

Comparison of bioassays for assessing sediment toxicity in Puget Sound. (Appendices included). Report for 1988-1989 (Final)

Technical Report Pastorok, R; Becker, D

This study evaluated the relative performance of several bioassays used to assess toxicity of Puget Sound sediments. Selected bioassays were conducted simultaneously on the same array of sediment samples, and direct comparisons were made among the various tests in relation to specific performance criteria. The bioassays and toxicity endpoints evaluated included the following: Amphipod test (Rhepoxynius abronius), percent mortality and abnormality; Amphipod test (Eohaustorius estuarius), percent mortality and abnormality; Juvenile geoduck (Panope generosa), percent mortality; Juvenile polychaete (Neanthes arenaceodentata), percent mortality and percent reduced biomass; Echinoderm embryo test (Dendraster excentricus), percent developmental abnormality and chromosomal abnormality; Bivalve larvae test (Mytilusmore »« less
Comparison of marine sediment toxicity test protocols for the amphipod Rhepoxynius abronius and the polychaete worm Nereis (Neanthes) arenaceodentata

Journal Article Anderson, B; Hunt, J; Phillips, B - Environmental Toxicology and Chemistry

The 10-d amphipod survival toxicity test protocol using Rhepoxynius abronius was compared to the 20-d polychaete worm growth and survival protocol using Nereis (Neanthes) arenaceodentata. Of the 341 sediment samples collected in California and tested over a 2-year period. 78% significantly inhibited R. abronius survival, whereas 2 and 26% significantly inhibited N. arenaceodentata survival and biomass, respectively. Statistical power associated with each protocol endpoint was determined by calculating the minimum significant difference (MSD) for each test protocol for this data set. The 90th percentile MSDs for R. abronius survival and N. arenaceodentata survival and biomass were 16, 36, and 56%,more »« less

Reference-area performance standards for Puget Sound

Technical Report

Chemical and biological conditions in the sediments at sites in three areas of Puget Sound were analyzed as part of the study. Analysis of sediments from Samish Bay, Holmes Harbor, and Carr Inlet included chemical concentrations, total organic carbon, acid-volatile sulfides, total solids, grain size distribution, and sediment toxicity as measured by amphipod mortality, bivalve larvae mortality and abnormality, echinoderm embryo mortality and abnormality, juvenile polychaete mortality and biomass, and saline Microtox bacterial luminescence bioassays. The performance standards developed for Puget Sound sediment reference sites will provide a consistent basis for comparison and use of sediment data collected by variousmore »« less
Toxicity of Halifax Harbour sediments: An evaluation of the Microtox solid phase bioassay

Conference Cook, N; Wells, P

Subtidal sediments were collected from 8 stations in Halifax Harbour, N.S., in July and August, 1992, to initiate a study of sediment toxicity and hazards near the proposed location of a sewage treatment plant and outfall. A set of 110 samples was evaluated. Interstitial water from aerobic surface (0--2cm) and anaerobic subsurface (2-4cm) sediments was analyzed by the Microtox{reg_sign} toxicity test protocol; the sediment particles were analyzed using the Microtox Solid Phase Test (SPT). Toxicity was expressed as 5, 15, and 30min-EC50`s for the interstitial samples, and 5min-EC50`s for the sediments, the endpoint being the inhibition of photoluminescence of Photobacteriummore »« less
Harmonization of standard toxicity test methods used in North America

Conference Ingersoll, C; Dwyer, F; Ankley, G

Over the past two years, Environment Canada (EC) and the US Environmental Protection Agency (EPA) have developed standard methods for conducting toxicity and bioaccumulation tests with freshwater, estuarine, and marine sediments. Existing ASTM methods were used as a basis to harmonize these methods for conducting testing with either field-collected or laboratory-spiked sediments. For freshwater toxicity tests, methods are described by EC and EPA for the amphipod Hyalella azteca and the midges Chironomus tentans and C. riparius. Endpoints include 10- to 14-d survival of growth. Methods are also described by EPA for conducting 28-d bioaccumulation tests with the oligochaete Lumbriculus variegatus.more »« less
