Air Quality Impacts from Oil and Gas Development (January 27)

Oil and gas development and hydraulic fracturing have received enormous attention over the past few years, and most of that attention has focused on the potential impacts of such development on water quality. However, the potential impacts on air quality from oil and gas development have received far less public and media attention and discussion. This two-hour program will assess the current scientific knowledge, regulatory requirements and policies regarding the impacts on air quality from oil and gas development and will address current initiatives at the state and national levels to further regulate and control those impacts.

A Global Assessment Of The Water Footprint Of Farm Animal Products, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

The increase in the consumption of animal products is likely to put further pressure on the world’s freshwater resources. This paper provides a comprehensive account of the water footprint of animal products, considering different production systems and feed composition per animal type and country. Nearly one-third of the total water footprint of agriculture in the world is related to the production of animal products. The water footprint of any animal product is larger than the water footprint of crop products with equivalent nutritional value. The average water footprint per calorie for beef is 20 times larger than for cereals and …

Effects Of Chemical And Mechanical Weathering Processes On The Degradation Of Plastic Debris On Marine Beaches, David A. Cooper

Electronic Thesis and Dissertation Repository

Plastics are an integral part of everyday life, and the use of plastic products for consumer goods, food packaging, recreational and commercial fishing and medical and sanitary applications continues to increase. The durability, low cost, light weight and hydrophobic nature of plastic make it a desirable material for numerous applications; however, these same characteristics make plastic debris in natural environments a pervasive problem. Increases in plastic use and low economic incentive for recovery, result in accumulation of debris in marine environments. Degradation of plastics through chemical weathering occurs in the open ocean or along shorelines where polymers are exposed to …

Calcium Montmorillonite Clay Reduces Urinary Biomarkers Of Fumonisin B₁ Exposure In Rats And Humans, Abraham Robinson, Natalie M. Johnson, A. Strey, John F. Taylor, Alicia Marroquin-Cardona, N. J. Mitchell, Evans Afriyie-Gyawu, Nii-Ayi Ankrah, Jonathan H. Williams, Jia-Sheng Wang, Pauline E. Jolly, R. J. Nachman, Timothy D. Phillips

Environmental Health Sciences Faculty Publications

Fumonisin B1 (FB1) is often a co-contaminant with aflatoxin (AF) in grains and may enhance AF’s carcinogenicity by acting as a cancer promoter. Calcium montmorillonite (i.e. NovaSil, NS) is a possible dietary intervention to help decrease chronic aflatoxin exposure where populations are at risk. Previous studies show that an oral dose of NS clay was able to reduce AF exposure in a Ghanaian population. In vitro analyses from our laboratory indicated that FB1 (like aflatoxin) could also be sorbed onto the surfaces of NS. Hence, our objectives were to evaluate the efficacy of NS clay to reduce urinary FB1 in …

Brief 3: Clustering Assessment: Enhancing Synergies Among Multilateral Environmental Agreements, Judith Wehrli

Governance and Sustainability Issue Brief Series

Against the background of a widely fragmented and diluted international environmental governance architecture, different reform options are currently being discussed. This issue brief considers whether streamlining international environmental regimes by grouping or ‘clustering’ international agreements could improve effectiveness and efficiency. It outlines the general idea of the clustering approach, draws lessons from the chemicals and waste cluster and examines the implications and potentials of clustering multilateral environmental agreements.

Beta Interferon-Mediated Activation Of Signal Transducer And Activator Of Transcription Protein 1 Interferes With Rickettsia Conorii Replication In Human Endothelial Cells, Punsiri M. Colonne, Marina Eremeeva, Sanjeev K. Sahni

Marina E. Eremeeva

Infection of the endothelial cell lining of blood vessels with Rickettsia conorii, the causative agent of Mediterranean spotted fever, results in endothelial activation. We investigated the effects of R. conorii infection on the status of the Janus kinase (JAK)-signal transducer and activator of transcription protein (STAT) signaling pathway in human microvascular endothelial cells (HMECs), the most relevant host cell type, in light of rickettsial tropism for microvascular endothelium in vivo. R. conoriiinfection induced phosphorylation of STAT1 on tyrosine 701 and serine 727 at 24, 48, and 72 h postinfection in HMECs. Employing transcription profile analysis and neutralizing …

Marina E. Eremeeva

Los Angeles and Orange Counties are known endemic areas for murine typhus in California; however, no recent reports of flea-borne rickettsioses are known from adjacent San Bernardino County. Sixty-five opossums (Didelphis virginiana) were trapped in the suburban residential and industrial zones of the southwestern part of San Bernardino County in 2007. Sixty out of 65 opossums were infested with fleas, primarily cat fleas, Ctenocephalides felis (Bouché, 1835). The flea minimum infection rate with Rickettsia felis was 13.3% in pooled samples and the prevalence was 23.7% in single fleas, with two gltA genotypes detected. In spite of historic …

Como meio de efetivação da proteção e desenvolvimento florestal, o Brasil adotou em sua política ambiental a criação do Sistema de Unidades de Conservação nas categorias, de proteção integral e uso sustentável. Uma alternativa viável é a regulação dos estoques de madeira no Estado por meio de Unidade de Conservação de Uso Sustentável. O que se pretende a partir deste ponto é analisar a possibilidade da criação de regulamentação …

Development Of Waste Collection Services On Rural Territory From Neamț County, Florin C. Mihai, Liviu Apostol

Florin C MIHAI

This paper analyzes the expansion of sanitation services in rural areas after the closure and rehabilitation of rural dumpistes having as deadline July 16, 2009. Following this period local authorities are forced to collect and dispose the waste generated in urban landfills from proximity until the transfer stations will be operational. Most of the rural population has no access to waste collection services, waste generated and uncollected are uncontrolled disposed polluting the local environment. Development of sanitation services is a basic condition for an efficient implementation of integrated waste management system at county level.

Food Benefit And Climate Warming Potential Of Nitrogen Fertilizer Uses In China, Hanqin Tian, Chaoqun (Crystal) Lu, Jerry Melillo, Wei Ren, Yao Huang, Xiaofeng Xu, Mingliang Liu, Chi Zhang, Guangsheng Chen, Shufen Pan, Jiyuan Liu, John Reilly

Chaoqun (Crystal) Lu

Chemical nitrogen (N) fertilizer has long been used to help meet the increasing food demands in China, the top N fertilizer consumer in the world. Growing concerns have been raised on the impacts of N fertilizer uses on food security and climate change, which is lack of quantification. Here we use a carbon–nitrogen (C–N) coupled ecosystem model, to quantify the food benefit and climate consequence of agronomic N addition in China over the six decades from 1949 to 2008. Results show that N fertilizer-induced crop yield and soil C sequestration had reached their peaks, while nitrous oxide (N2O) emission continued …

Simulation Of Coastal Inundation Instigated By Storm Surge And River Discharge In The Chesapeake Bay Using Sub-Grid Modeling Coupled With Lidar Data, J. D. Loftis, H. V. Wang

Presentations

Sub-grid modeling is a novel method by which water level elevations on the sub-grid level can be obtained through the combination of water levels and velocities efficiently calculated at the coarse computational grid, the discretized bathymetric depths, and local friction parameters without resorting to solve the full set of equations. Sub-grid technology essentially allows velocity to be determined rationally and efficiently at the sub-grid level. This salient feature enables coastal flooding to be addressed in a single cross-scale model from the ocean to the upstream river channel without overly refining the grid resolution. To this end, high-resolution DEMs will be …

Lacking A Connection To A Community Water System: Water Quality And Human Health Impacts In El Paso Colonias, Yolanda Jane Mcdonald

Open Access Theses & Dissertations

Water-borne disease and its symptoms, such as stomach cramps and diarrhea, are a serious concern in areas that are not connected to a public water system. To investigate the impacts of not being connected to a community water system, I surveyed households in El Paso County colonias that were not connected to a community water system (household n = 75, individual n= 293) and households that were connected to a community water system (household n = 75, individual n= 320). I conducted 150 door-to-door surveys and tested water samples from each household for free residual chlorine level, turbidity level, presence …
