This book was released on 1901 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of exposure to the water-soluble fraction (WSF) of Norman Wells crude oil (NWC) on the feeding behaviour of rainbow trout were studied. Trout were exposed to WSF of NWC mixed at 10, 25, 50, 100, 200 and 400 mg/L nominal concentrations. Exposures lasted 14 days with complete, daily renewal of the WSF in a static, non-aerated system. Nominal hydrocarbon (HC) concentrations were compared with measured concentrations by extracting water with hexane and analyzing the samples with mass spectroscopy gas chromatography. At 400 mg/L nominal (8.27 mg/L measured) HC concentrations, all the fish died within 96 hours. Between 50 mg/L and 200 mg/L nominal concentrations (0.55-1.92 mg/L measured concentrations), feeding became noticeably slower within 2 days and stopped completely by 3 days. The fish displayed signs of narcosis and swimming impairment with $>$92% decrease in food consumption. The 'lowest observable effect' concentration (LOEC) was 25 mg/L nominal (0.31 mg/L measured). Feeding slowed after 5 days resulting in a decrease in food consumption $>$54% after 14 days when compared to controls. No effects on feeding behaviour or body water content were evident at the 'no observable effect' concentration (NOEC) of 10 mg/L nominal (0.14 mg/L measured) HC concentrations. The maximum allowable toxicant concentration (MATC) for the alteration of feeding behaviour in young rainbow trout ranged between NOEC and LOEC at 0.14 to 0.31 mg measured HC per litre of water. No significant trend was seen in the wet weight and lengths of the fish during the experiment probably because of the short exposure duration (14 days). There was a small increase in body water content in the exposed fish relative to unexposed controls.

Book Synopsis Identification of Compounds in Heavy Fuel Oil 7102 that are Chronically Toxic to Rainbow Trout (Oncorhynchus Mykiss) Embryos by : Julie Elizabeth Adams
Download or read book Identification of Compounds in Heavy Fuel Oil 7102 that are Chronically Toxic to Rainbow Trout (Oncorhynchus Mykiss) Embryos written by Julie Elizabeth Adams and published by . This book was released on 2013 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spilled heavy fuel oil (HFO) sinks within the water column and accumulates in sediments, affecting aquatic organisms that are not typically exposed to oils that float. Previously, the 3-4 ring alkyl substituted polycyclic aromatic hydrocarbons (PAHs) have been identified as the major toxic components in crude oil. Since HFO is comprised of higher concentrations of 3-4 ringed alkyl PAH and an abundance of 5-6 ringed PAH relative to crude oil, it is predicted to be more toxic to the early life stages of fish. An effects-driven chemical fractionation (EDCF) of HFO 7102 was undertaken to establish the toxicity relative to crude oil, and to identify the compounds that are bioavailable and chronically toxic to the early life stages of fish. In this EDCF, the complex HFO 7102 mixture was separated by low temperature vacuum distillation into three distinct fractions, 2, 3 and 4. Each fraction was assessed using a chronic bioassay to determine whether it contained components that caused toxicity to rainbow trout embryos similar to that of the whole oil. Acute bioassays with juvenile trout demonstrated the presence of compounds that induce cytochrome P450 enzymes, an indicator of exposure to PAH. Fraction 3, the fraction more toxic than the parent mixture, was further separated by cold acetone extraction into fraction 3-1 (PAH-rich extract) and fraction 3-2 (wax residue), and assessed with the same bioassays. Simultaneous chemical analysis with bioassays guided the fractionation, and identified compounds abundant and consistently present in toxic fractions. Due to resistance to dispersion of HFO, a chemical dispersant was used with vigorous mixing to drive the maximum amount of oil into solution to minimize the potential for false negatives and the volume of test material used. The potency of HFO 7102 and its fractions were also measured using water accommodated fractions (WAFs) produced by a continuous flow system of water flowing through oil coated gravel. Both exposure methods traced the toxicity from whole oil into fractions containing higher concentrations of 3-4 ring alkyl PAH, similar to crude oil. This research is the first toxicological assessment of HFO 7102, which is essential for determining the risk of spills of HFO to fish, and whether the risk of oils can be predicted from their alkyl PAH composition.

This book was released on 2005 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 3 million gallons of oil or refined petroleum products are spilled into U.S. waters every year. Oil dispersants (chemical agents such as surfactants, solvents, and other compounds) are used to reduce the effect of oil spills by changing the chemical and physical properties of the oil. By enhancing the amount of oil that physically mixes into the water, dispersants can reduce the potential that a surface slick will contaminate shoreline habitats. Although called for in the Oil Pollution Act of 1990 as a tool for minimizing the impact of oil spills, the use of chemical dispersants has long been controversial. This book reviews the adequacy of existing information and ongoing research regarding the effectiveness of dispersants as an oil spill response technique, as well as the effect of dispersed oil on marine and coastal ecosystems. Oil Spill Dispersants also includes recommended steps for policy makers faced with making hard choices regarding the use of dispersants as part of spill contingency planning efforts or during actual spills.

Book Synopsis Analysis of Oil Sand Process Water Toxicity in Early Life Stage Rainbow Trout (Oncorhynchus Mykiss) Using Biomimetic Extraction-solid Phase Microextraction (BE-SPME) by : Nina Piggott

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil sand process water (OSPW) contains a complex mixture of organic compounds that can be toxic to aquatic life. To develop an animal-free method for measuring the toxicity of the organic fraction of OSPW, rainbow trout (Oncorhynchus mykiss) eyed embryos were exposed to OSPW for 30 days. Biomimetic solid-phase microextraction (BE-SPME) was used to quantify the concentration of bioavailable organic compounds. Endpoints evaluated were mortality, development (weight, length, and yolk sac absorption), and deformities. The LC50 of the bioavailable fraction was 21.95 mM dimethyl-naphthalene (DMN). Toxicity thresholds for length and weight were 3.96 mM and 8.91 mM, respectively. Deformities were indicative of cardiovascular toxicity and included pericardial and yolk sac edema and craniofacial malformations. The EC25 for deformities was 9.53 mM DMN. Study results support the development of water quality guidelines and the use of BE-SPME as a rapid, animal-free method to assess the toxicity of OSPW.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies by our laboratory on sublethal effects of petroleum fractions on behavior of H. americanus and N. obsoletus are summarized in an attempt to clarify contradictory results and to gain an understanding of the underlying principles. There appear a surprising number of similarities in the way specific petroleum fractions affect the behavior of a crustacean arthropod and a gastropod mollusc. Acute toxicity, caused perhaps by the branched-cyclic fraction, was evident in short term exposures to whole No. 2 fuel oil at 50 ppM and kerosene in .mu.l/100 l quantities. Feeding attraction, caused perhaps by the branched-cyclic fraction in lower concentrations, was seen after exposure to 1 ppM No. 2 fuel oil, and to kerosene and its branched-cyclic and polar-aromatic fractions in .mu.l/100 l quantities. Repulsion and feeding inhibition, caused perhaps by the polar-aromatic fraction which contains most of the soluble materials, was observed in response to many concentrations of No. 2 fuel oil and kerosene, and their soluble fractions down to 1 ppB levels. No effect was apparent in exposures to the lower concentrations of solubles of .1 and .01 ppM No. 2 fuel oil and to solubles of La Rosa crude at 10 ppB. The hypothesis is advanced that specific hydrocarbon fractions in specific amounts are responsible for distinct behavioral changes; these fractions are present in varying quantities in different oils; and the changes in behavior are general enough to affect a large number of marine invertebrates in a similar manner.
