Evaluation Of Toxicity, Bioavailability And Speciation Of Lead, Zinc And Cadmium In Mine/Mill Wastewaters, Mujde Erten-Unal, Bobby G. Wixson, Nord Gale, Jerry L. Pitt

Civil & Environmental Engineering Faculty Publications

The toxicity of common compounds of lead, cadmium and zinc was evaluated in waters similar to that found in the world's largest lead producing area in Missouri. Static, acute toxicity tests were performed using fathead minnows (Pimephales promelas) and water fleas (Daphnia magna) respectively. Test organisms were subjected to varying amounts of sulfide, carbonate, chloride and sulfate salts of lead, zinc and cadmium mixed in hard, alkaline waters typical to this region. Median lethal concentrations were calculated using nominal versus measured metal concentrations. Measured metal concentrations included four different metal fractionation (extraction/filtration) techniques at different pH …

1080 Operational Procedures Manual - Second Edition, Agriculture Western Australia

Biosecurity published reports

Sodium fluoroacetate (1080) is an extremely toxic substance which can be a danger to humans if handled incorrectly. At the same time 1080 is the most effective and efficient poison for the control of Western Australia's main vertebrate pest species including rabbits, wild dogs and foxes. One of the main reasons for its usefulness in Western Australia is that many native animals have a high tolerance to it and so may not be affected by baiting.

Industry Resource Protection Program (IRPP) This program, part of Agriculture Western Australia, supports feral animal control carried out by its staff and community groups. …

Ecological Water Treatment System For Removal Of Phosphorus And Nitrogen From Polluted Water, Ray W. Drenner, Donald J. Day, Stacy J. Basham, J. Durward Smith, Susan I. Jensen

School of Natural Resources: Faculty Publications

We propose that phosphorus and nitrogen can be removed from polluted water using an ecological water treatment system consisting of periphyton and fish. In the proposed system, polluted water flows through a series of vessels, and the nutrients are taken up by periphyton growing on porous screens. Algal-grazing fish feed on the periphyton and either assimilate or egest the nutrients in mucus-bound feces that settle from the water into a sediment trap. Both the fish and their feces can be harvested as nutrient sinks. In this study we examined the effects of an algal-grazing cichlid (Tilapia mossambica) and …

An Examination Of Environmental Sensitivity Among Supporters Of An Outdoor Recreation Area, Rodney James Blackman

Dissertations and Theses @ UNI

The environment as an issue has been prominently before the public for over three decades. Yet the question of how much people know about the natural environment and how committed they are to the environment has seldom been considered in research literature. Research of this nature is needed because without it individuals interested in the preservation and conservation of the environment cannot be sure how their efforts to increase people's environmental sensitivity should be applied. The purpose of this study was to examine the level and extent of environmental sensitivity among supporters of an outdoor recreation area/facility in northeast Iowa. …

Development And Standardization Of A Short-Term Assay For Evaluating Polluted Estuarine And Coastal Environments: The Medaka Embryo-Larval Assay, Michael Frederick Helmstetter

OES Theses and Dissertations

The eggs of the Japanese medaka (Oryzias latipes) were employed in a number of studies to develop a routine, standardized assay which can assess the acute and sublethal impacts of individual toxicants and complex mixtures. The eggs of this Cyprinodont minnow were topically treated with each toxicant or mixture dissolved in membrane permeable dimethylsulfoxide (DMSO) solvent. Nine chemicals were initially evaluated with two, pentachlorophenol (PCP) and tributyltin chloride (TBTCl), subsequently selected for extensive evaluations of salinity tolerance and the accuracy of the topical exposure method for representing a typical immersion exposure. The amount of material actually penetrating the eggs was …

Gas Chromatographic Method For Determination Of 28 Volatile Organic Compounds Emitted From A Sewerage Plant, Yeming Sun

Theses

In this study, 28 volatile organic compounds (VOCs) emitted from the Linden Roselle Sewerage Authority Plant (LRSA) were monitered. The determination by gas chromatography (GC) is presented. This work emphasizes the collection of whole air samples, using a canister-based sampling system with cryogenic concentration. An appropriate temperature program was selected to obtain the best sample separation. The procedure for the identification of 28 standard gas mixture was achieved by comparing the chromatograms of sample with those of the specific groups of target compounds, as well as by comparing the sample with the results from GC Mass spectrometeric analysis. Because of …

The sample composition was : 62% foundry baghouse dust (or 60% if 2% clay as added to the sample), 4.5% cement, 14% coal fly ash, 19.5% water. Pentachlorophenol was chosen as represen¬tative of the organic contamination. All tests were performed after curing the samples at 22°C, 98% Rh for 28 days. The …

Benzo(A)Pyrene Ingested From Composite Meals : Analysis And Method Development Related To Total Human Exposure, Che-Han Hsu

Theses

Polycyclic aromatic hydrocarbons including benzo[a]pyrene (BaP) have been known for many years to be environmental carcinogen. Moreover, B(a)P has often been used as an indi¬cator for the carcinogenic potency of environmental matter. One of its exposure pathways, ingestion, may possibly be more important than other routes, conventionally studied such as inhalation. The purposes of this thesis are 1) to analyze the B(a)P concentrations in weekly composite and some daily meals obtained in the Total Human Exposure to Environmental Substances (THEES) study, 2) to develop techniques which can measure the levels of B(a)P in foods accurately and effici¬ently, 3) to compare …

Quantitative Determination Of Formaldehyde In Ambient Air, Wen-Shao Chou

Theses

Formaldehyde has been shown in the laboratory to play a critical role in the chemistry of polluted air. The method which we discuss in this paper was evaluated under practical field conditions in the Northern New Jersey Staten Island Urban Air Toxics Project. Formaldehyde in ambient air is concentrated and derived by passing a known quantity of air through a silica column impregnated with 2,4-dinitrophenylhydrazine (DNPH). The silica is eluted with acetonitrile and the concentration of formaldehyde is determined by High Performance Liquid Chromatograph (HPLC) with UV detection. A description of procedural details for coating silica cartridges with 2,4-DNPH acidified …

Degradation Of Refractory Organic Pollutants In Tar, Water And Soil Matrices By Ozone Or Hydrogen Peroxide With Ultraviolet Light, Liang-Jiun Uang

Theses

The objective of this research is to develop a method to degrade refractory Tar materials, higher molecular weight 3-5 ring Poly Aromatic Hydrocarbons (PAH's) or degrading these highly refractory PAH structures so that they are amenable to further treatment by biological or chemical methods. The process utilized to achieve this is to treat contaminated soils or tar materials with hydrogen peroxide or ozone plus ultraviolet light. Analysis of 27 specific PAH's was done by gas chromatograph (Flame Ionization Detection) for the reactants and products. The contaminated soil showed significantly lower levels of these PAH's after treatment.

Microbial Competition In The Biodegradation Of Phenol, Mary Ellen Frank

Theses

Three phenol degraders were isolated from the mixed liquor of the Livingston, NJ municipal treatment plant. Shaker flask experiments using one of the degraders (a Pseudomonas sp.) resulted in the determination of its kinetic rate constants. The second phenol degrader (a Xanthamonas) lost its phenol degrading ability while being stored, and its kinetic rate constants could not be determined. The third phenol degrader (a Pseudomonas cepacia) formed flocs which interfered with the spectrophotometric determination of biomass and therefore its kinetic rate constants also could not be determined.

Mixed culture experiments were carried out using a the Pseudomonas sp. and a …

Study Of An Analytical Method For Benzo(A)Pyrene Metabolites In Human Urine, Zheng Ouyang

Theses

A method developed by Becher and Bjorseth for analysis of PAH metabolites in urine was employed to investigate human exposure to benzo(a)pyrene (BaP) - an ubiquitous environmental carcinogen. Preliminary results are presented showing the relationship between exposure to BaP and urinary elimination. Although the correlation between the two variables is not statistically significant, there appears to be a positive association with selected exposure varibles such as smoking. The identification of an association may establish urinary BaP as a marker of exposure.

However, detailed study of the analytical procedure indicated that recoveries with this method were as low as 3-8% for …

Thermal Desorption Of Hazardous And Toxic Organic Compounds, Manuel S. Nolau

Theses

The purpose of this thesis is to study the thermal desorption behavior of toxic organic compounds, specifically o-xylene, p-xylene, ethyl benzene, p-chlorotoluene, and anthracene, from soil with respect to temperature and time, and to develop a mathematical model that will describe this desorption behavior. The model will allow prediction of the concentration of an organic contaminant in commercial soil desorption system over time given a known set of parameters of the specific chemical as well as flow rate and temperature. For this purpose, two sets of experiments were done: These are identified as 1. Thermal desorption and 2. plug flow …
