Odor and gaseous emissions from the swine industry are of concern for the wellbeing of humans and livestock. Additives applied to the swine manure surface are popular, marketed products to solve this problem and relatively inexpensive and easy for farmers to use. There is no scientific data evaluating the effectiveness of many of these products. We evaluated 12 manure additive products that are currently being marketed on their effectiveness in mitigating odor and gaseous emissions from swine manure. We used a pilot-scale system simulating the storage of swine manure with a controlled ventilation of headspace and periodic addition of manure ...

Single-Use Plastics And Covid-19: Scientific Evidence And Environmental Regulations, Robert C. Hale, Bk Song
VIMS Articles
Waste plastics are a serious and growing environmental problem. Less than 10% of plastics are recycled, with most discarded in landfills, incinerated, or simply abandoned.1 Single-use plastics constitute about half of plastic waste. While most plastics are used and initially disposed of on land, much eventually enters aquatic ecosystems.2 Wildlife mortalities result from encounters (e.g., ingestion and entanglement) with large debris, including plastic bags. Such bags are excluded from many recycling programs, as they can entangle machinery. Most plastics do not readily biodegrade in the environment. However, they can be embrittled by UV exposure and fragment into ...

Land Application Of Sewage Sludge: Physiological And Biochemical Response Of The Rio Grande Tomato, Nabil Charchar, Ali Elafri, Redwane Rais, Halassi Ismahen
Journal of Bioresource Management
Treated wastewater produces sewage sludge as a by-product that may have beneficial implications on agricultural practices. The effects of sludge amendments on growth, morphological and biochemical characteristics of the agro-industrial Tomato cultivar Rio Grande were observed. A pot culture experiment was carried out during 4 months (16 February 2019 to 18 June 2019), at an experimental green house in the locality of Salah Soufi, Guelma, north-eastern Algeria. There were significant differences between soil and sewage sludge samples. Total nitrogen (20.58 mg/kg) was more available in sewage sludge than in soil (N = 2.09 ± 0.3 mg/kg). In ...

Houston, We Have A Problem: Humanity & Home In 2001: A Space Odyssey, Charlotte Grace Mcgill Wood
2020 JHU Richard Macksey National Undergraduate Humanities Research Symposium
Stanley Kubrick's watershed film 2001: A Space Odyssey (1968) is epic in its undertaking. In just under three hours, Kubrick attempts to capture the totality of human history, beginning before the evolution of humankind as we know it and ending in a kind of post-physical dream space. The question of the environment's role weighs heavily throughout, as humankind becomes increasingly divorced from the Earth and begins a love affair with the wider universe. This affair is, of course, mediated. It is possible only because of suits and ships, tools invented by and for humans that allow them to ...

Understanding The Toxicity Of Single Hydrocarbons, Oil, And Dispersed Oil: A Species Sensitivity Assessment For Five Atlantic Coral Species, Nicholas R. Turner
HCNSO Student Theses and Dissertations
Coral reefs are keystone coastal ecosystems that are at risk of exposure to petroleum hydrocarbons from a range of sources, including oil spill incidents and chronic runoff, and are usually one of the highest valued natural resources for protection in Net Environmental Benefit Analysis (NEBA)/Spill Impact Mitigation Assessment (SIMA) of response methods and environmental damage. Previous research evaluating hydrocarbon impacts to corals has resulted in no clear characterization of sensitivity, as work has generally focused on higher-level effects, compounded by significant variability in experimental methodology. This represents an important knowledge gap in oil spill preparedness and response as it ...

Georgia Journal of Science
Atmospheric carbon dioxide is rising at an accelerated rated due to increased anthropogenic activities. Metals have also been a noted problem; however, little research has addressed combined exposure of both pollutants to sensitive, calcifying organisms in freshwater habitats. This study examined copper accumulation (over 7 d) and activity of the antioxidant enzymes, catalase and glutathione peroxidase (over 2 d), in the freshwater common pond snail, Lymnaea stagnalis, after exposure to ambient and increased (2000 µatm) CO2 and copper (control, 5, and 20 µg/L). Results demonstrated increased copper accumulation in soft tissue of snails exposed to copper; however, exposure ...

Cigarette butts are the most littered item in the world and contain over 4,000 chemicals, including the organic compound nicotine (Slaughter et al. 2011). Billions of cigarette butts are littered each year which may wash into bodies of water, impacting the local wildlife. To determine how introduced chemicals impact the environment, it is important to study its effects on indicator species. Amphibians, such as Lithobates catebeianus, act as indicator species due to their extreme sensitivity to chemical changes in its environment. The purpose of this research project was to obtain data to help determine the impact nicotine accumulation has ...

Comparing Statistical Analyses To Estimate Thresholds In Ecotoxicology, Marcos Krull
VIMS Articles
Different methods are used in ecotoxicology to estimate thresholds in survival data. This paper uses Monte Carlo simulations to evaluate the accuracy of three methods (maximum likelihood (MLE) and Markov Chain Monte Carlo estimates (Bayesian) of the no-effect concentration (NEC) model and Piecewise regression) in estimating true and apparent thresholds in survival experiments with datasets having different slopes, background mortalities, and experimental designs. Datasets were generated with models that include a threshold parameter (NEC) or not (log-logistic). Accuracy was estimated using root-mean square errors (RMSEs), and RMSE ratios were used to estimate the relative improvement in accuracy by each design ...

Gaseous emissions, a side effect of livestock and poultry production, need to be mitigated to improve sustainability. Emissions of ammonia (NH3), hydrogen sulfide (H2S), greenhouse gases (GHGs), and odorous volatile organic compounds (VOCs) have a detrimental effect on the environment, climate, and quality of life in rural communities. We are building on previous research to bring advanced oxidation technologies from the lab to the farm. To date, we have shown that ultraviolet A (UV-A) has the potential to mitigate selected odorous gases and GHGs in the context of swine production. Much less research on emissions mitigation has been conducted in ...

Poor sanitation exacerbates adverse health outcomes such as infectious disease, diarrhea and childhood stunting. People of India suffer from disproportionately high rates of poor sanitation. Diarrheal diseases are preventable and better sanitation can reduce disease transmission through improved access to latrines, hygiene education and clean water. A significant concentration of behaviors related to poor sanitation occurring in India requires sustainability and an assessment of programs working towards improving water access, sanitation and hygiene (WASH). We assessed the health and environmental impact of Non-Governmental Organizations (NGOs) such as Sarboday Sangha and Water for People which implemented WASH projects in about 141 ...

Good Mums: A Gender Equality Perspective On The Constructions Of The Mother In Handwashing Campaigns, Sue Cavill, Chelsea Huggett
wH2O: The Journal of Gender and Water
The first part of this paper provides a brief overview of the framing of women in hygiene interventions. The following section provides a review of the literature on best practices for handwashing and hygiene, as framed by discourses on the good mother. The goal of this paper is to illustrate how promotional approaches are targeting mothers to change handwashing and hygiene behavior, and to contrast such interventions with the possibility of more gender transformative approaches. We argue that women don’t always implement the handwashing practices they would prefer. This is clearly not due to laziness and thoughtlessness, and it ...

Barriers And Bias: Women In Water Utilities Are Breaking Them All, Swati Hegde
wH2O: The Journal of Gender and Water
Around the world, women are the mainstays of society, from raising children to supporting families to caring for the needy. In developing countries, they are also usually responsible for collecting and providing water for the family. In doing so, their time, health, safety, education and income are compromised. Outdated and undisputed social norms create the biases that force women to bear the responsibility to secure and distribute water, thereby creating barriers to women’s advancement in educational opportunities and significantly reducing income-earning potential. Similarly, in the developed world, outdated social norms create biases and barriers in the water industry that ...

The Connection Between Indoor Air Quality And Mental Health Outcomes, William L. Taylor
Theses and Dissertations
Mental health among United States citizens, military members, and veterans warrant research into factors not fully considered for their effects on mental health. The built environment is increasingly recognized as a potential influence on the mental health of occupants. Specifically, indoor air quality is theorized to contribute to mental illness. Through the development of a literature review, specific air pollutants common in the built environment were identified, and the mechanisms behind their effect on mental health were explored. A model framework is outlined, estimating the number of cases of major depressive disorder attributable to indoor exposure to particulate matter. The ...
