Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken to help quantify the potential effects of sediment contamination with ordnance compounds to the benthic biota. This objective was achieved by conducting toxicity tests with sediments spiked with ordnance compounds, using whole sediment tests with a benthic amphipod and porewater tests with different life stages of three marine organisms. The selection of ordnance compounds and porewater test species for this study was based on the results of previous studies, where a database for toxicity of eight different ordnance compounds to six marine species was generated. The ordnance compounds selected for the present study were 2,6-dinitrotoluene (2,6-DNT), tetryl and picric acid. Two kinds of sediments were spiked with each ordnance compound. Spiked sediments were allowed to equilibrate for approximately 1 week prior to porewater extraction and to toxicity testing of the solid-phase. Solid-phase tests were conducted using the 10-day acute test with the benthic amphipod, Ampelisca abdita. Porewater toxicity tests were conducted using the 48-hour embryological development test with the sea urchin, Arbacia punctulata, the 96-hour zoospore germination and germling growth test with the macro-alga, Ulva fasciata, and the 7-day survival and reproduction test with the burrowing polychaete, Dinophilus gyroclliatus. These species and endpoints were identified previously as being among the most sensitive for these ordnance compounds.

Book Synopsis Sediment Pore-Water Toxicity Test Results and Preliminary Toxicity Identification of Post-Landfall Pore-Water Samples Collected Following the Deepwater Horizon Oil Release, Gulf of Mexico, 2010 by : U.S. Department of the Interior
Download or read book Sediment Pore-Water Toxicity Test Results and Preliminary Toxicity Identification of Post-Landfall Pore-Water Samples Collected Following the Deepwater Horizon Oil Release, Gulf of Mexico, 2010 written by U.S. Department of the Interior and published by Createspace Independent Publishing Platform. This book was released on 2014-02-19 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pore water from coastal beach and marsh sediments from the northern Gulf of Mexico, pre- and post-landfall of the Deepwater Horizon oil release, were collected and evaluated for toxicity with the sea urchin fertilization and embryological development assays. There were 17 pre-landfall samples and 49 post-landfall samples tested using both assays. Toxicity was determined in four pre-landfall sites and in seven post-landfall sites in one or both assays as compared to a known reference sediment pore-water sample collected in Aransas Bay, Texas. Further analysis and testing of five of the post-landfall toxic samples utilizing Toxicity Identification Evaluation techniques indicated that ammonia, and to a lesser extent metals, contributed to most, if not all, of the observed toxicity in four of the five samples. Results of one sample (MS–39) indicated evidence that ammonia, metals, and non-ionic organics were contributing to the observed toxicity.

Book Synopsis Toxicity of U.S. Waterway Sediments with Particular Reference to the New York Harbor Area by : RA. Jones

This book was released on 1988 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted in the mid- to late-1970s on the toxicity of elutriate test mixtures of water and sediment from U.S. harbors and waterways to grass shrimp or daphnia. While for many waterway sediments, 20 to 30% mortality was found after 96-h exposure, those of the New York harbor area showed somewhat greater toxicity. The specific cause of the mortalities was not investigated at that time. It is known that the sediments contained a wide variety of chemical contaminants which, if available to the organisms, could be toxic to them. More than 30 chemical parameters, including heavy metals and chlorinated hydrocarbon pesticides, were measured in the sediments; of the parameters measured, only ammonia was released in sufficient amounts to potentially cause acute lethality in the test waters associated with the sediments. Recent review of the data showed that there is a relationship between the concentration of ammonia in the sediment/water mixtures (elutriates) and the mortality of grass shrimp in the tests. Furthermore, the concentrations that appeared to cause about 50% mortality of the grass shrimp in the 96-h exposure were about the level of 96-h LC50 to grass shrimp for ammonia.

Download or read book Reducing the Effects of Total Ammonia in 10-Day Sediment Toxicity Tests with the Amphipod, Rhepoxynius Abronius written by CJ. Ferguson and published by . This book was released on 1996 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment toxicity tests are used to measure the effects of contaminants in sediment and are important management tools for agencies that regulate dredging and dredged material disposal, wastewater discharges, and other activities that might affect the aquatic environment. The interpretation of the results of routine toxicity tests can, however, be confounded by naturally occurring factors, such as ammonia, sulfides, sediment grain size, and salinity. Ammonia has been suspected for many years to be a sediment toxicant. It is only recently that the sensitivity of routine test organisms to ammonia has been quantified, and even more recently that dose-responses have been related to ammonia concentrations that occur in standard sediment toxicity tests. The first objective of this study was to compare the effects of ammonia in sediment toxicity tests under two pore water ammonia reduction procedures. The first procedure reduced total pore water ammonia from test sediments by replacing overlying water two times in a 24-h period. The second procedure used natural bacterial processes to reduce pore water ammonia. The second objective was to evaluate the current no-effect concentrations (originally based on 96-h water-only toxicity tests) using the overlying- water-exchange procedure. The final objective was to determine whether ammonia concentrations would increase to toxic levels in sediments that had naturally reached no-effect concentrations, but that were then physically disturbed. The marine amphipod, Rhepoxynius abronius, was exposed to sediments with low (?30 mg/L), moderate (? 100 mg/L), and high (?200 mg/L) initial concentrations of pore water total ammonia in five separate 10-day toxicity tests. One test followed standard protocols (ASTM E 1367-90). Two tests were initiated after pore water ammonia concentrations were reduced by overlying water exchange to

Book Synopsis Toxicity of Chlorine-Produced Oxidants to Estuarine Copepods by : MS. Beaven
Download or read book Toxicity of Chlorine-Produced Oxidants to Estuarine Copepods written by MS. Beaven and published by . This book was released on 1980 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The toxicity of chlorine to one estuarine copepod, Acartia tonsa, appeared to be a simple dose response, that is, doubling the times of exposure had the same effect on mortalities as doubling the concentration of the toxicant. Chlorine toxicity to at least one of the other species tested, Eurytemora affinis, did not follow a simple dose response; changing the times of exposure affected mortalities differently, depending on the dose concentration and the temperature. The relative toxicity of chlorine to the four species tested varied with time and temperature.
