Climate variability and change are issues of growing public health importance. Numerous studies have documented risks of extreme heat on human health in different locations around the world. Strategies to prevent heat-related morbidity and reduce disparities are possible but require improved knowledge of health outcomes during hot days at a small-scale level as important within-city variability in local weather conditions, socio-demographic composition, and access to air conditioning (AC) may exist. We analyzed hospitalization data for three unique climate regions of San Diego County alongside temperature data spanning 14 years to quantify the health impact of ambient air temperature at varying …

Assessing Public Health Burden Associated With Exposure To Ambient Black Carbon In The United States, Ying Li, Daven K. Henze, Darby Jack, Barron H. Henderson, Patrick L. Kinney

Ying Li

Black carbon (BC) is a significant component of fine particulate matter (PM2.5) air pollution, which has been linked to a series of adverse health effects, in particular premature mortality. Recent scientific research indicates that BC also plays an important role in climate change. Therefore, controlling black carbon emissions provides an opportunity for a double dividend. This study quantifies the national burden of mortality and morbidity attributable to exposure to ambient BC in the United States (US). We use GEOS–Chem, a global 3-D model of atmospheric composition to estimate the 2010 annual average BC levels at 0.5 x 0.667° resolution, and …

The Deepwater Horizon (DWH) oil spill in the Gulf of Mexico was the largest maritime oil spill in history
resulting in the accumulation of genotoxic substances in the air, soil, and water. This has potential far-
reaching health impacts on cleanup field workers and on the populations living in the contaminated
coastal areas. We have employed portable airborne particulate matter samplers (SKC Biosampler Im-
pinger) and a genetically engineered bacterial reporter system (umu-ChromoTest from EBPI) to de-
termine levels of genotoxicity of air samples collected from highly contaminated areas of coastal
Louisiana including Grand Isle, Port Fourchon, and Elmer's Island …


‘Wannabe Toxic-Free?’ From Precautionary Consumption To Corporeal Citizenship, Dayna Scott, Jennie Haw, Robyn Lee Nov 2016

‘Wannabe Toxic-Free?’ From Precautionary Consumption To Corporeal Citizenship, Dayna Scott, Jennie Haw, Robyn Lee

Dayna N. Scott

Ecological citizens are increasingly encouraged to adopt ‘precautionary consumption’ – a set of practices aimed at shielding them from the potential health harms of exposures to everyday toxics. The utility and the effects of precautionary consumption in relation to common chemical exposures are investigated. Precautionary consumption is not only of questionable utility, but is fundamentally misguided as an approach for inspiring antitoxics organizing. The failure of this approach is in part due to its assumption of a naturally bounded, autonomous individual who is able to maintain an impermeable boundary between herself and the environment. Drawing on the work of material …

Implementing A Community-Based Social Marketing Project To Improve Agricultural Worker Health, Joan D. Flocks, Leslie Clarke, Stan Albrecht, Carol Bryant, Paul Monaghan, Holly Baker

Joan D. Flocks

The Together for Agricultural Safety project is a community-based social marketing project working to reduce the adverse health effects of pesticide exposure among fernery and nursery workers in Florida. In 3 years, the collaboration between university and community researchers has embodied many of the principles of community-based research while completing multiple stages of formative data collection required for a social marketing project. This hybrid approach to developing a health intervention for a minority community has been successful in its early stages because the community partners are organized, empowered, and motivated to execute research activities with the assistance of academic partners. …


Pesticide Policy And Farmworker Health, Joan D. Flocks Apr 2016

Pesticide Policy And Farmworker Health, Joan D. Flocks

Joan D. Flocks

Although data on the carcinogenicity of agricultural pesticides are still being generated and are thus incomplete, research such as the Agricultural Health Study indicates that populations with increased, regular exposure to pesticides have high rates of a variety of cancers (National Institutes of Health & Environmental Protection Agency 2008). Policies that regulate toxins such as pesticides are envisioned by the public to be empirical and objective, but toxins are socially produced and their regulation is just as often based on political and economic factors as it is on science (Luke 2000). This does not bode well for farm- workers who …

Background: β-thujaplicin (β-Th), also known as hinokitiol, naturally occurs in cedar mulch, is found in personal care products and has in vitro antitumor activities. It is antibacterial and antifungal, but has not been tested on soil. Scedosporium apiospermum (Sce) is an emerging “extremophile” fungal pathogen found in built outdoor environments. Purpose: Pilot β-Th as “natural” soil antimicrobial or for isolation of extremophiles, and to explore β-Th resistance as selective advantage to Sce in mulched landscape. Methods: A variety of outdoor and indoor environments were used for 2 sets of 24 paired soil samples. Soil/H20 slurry (0.1 ml) was spread on …


The Shellfish Corner -- Water Quality And Culture Of Shellfish In Prohibited Waters, Michael A. Rice Jan 2016

The Shellfish Corner -- Water Quality And Culture Of Shellfish In Prohibited Waters, Michael A. Rice

Michael A Rice

In the United States, water quality standards for shellfishing and shellfish aquaculture waters have been governed since 1925 by the National Shellfish Sanitation Program (NSSP) first administered by the United States Public Health Service. With the greater popularity of aquacultured shellfish in the United States and the growth of market demand, seed availability is cited as one of the most pressing issues for the industry. The early recognition by ISSC of shellfish seed under certain conditions as being exempt from NSSP water quality classification requirements has already removed one of the largest regulatory barriers to expansion of seed production in …


Our Chemical Selves : Gender, Toxics, And Environmental Health, Dayna Scott Oct 2015

Our Chemical Selves : Gender, Toxics, And Environmental Health, Dayna Scott

Dayna N. Scott

Everyday exposures to chemicals found in homes, schools, and workplaces are having devastating consequences on human health. These toxic exposures derive from common personal care products and cosmetics, household cleaners, pharmaceuticals, furniture, the food we eat, the water we drink, and even the air we breathe. Our Chemical Selves examines the impact of toxics on the long-term health of Canadians. Written by leading researchers in science, law, and public policy, the chapters in this collection reveal that while exposures to chemicals are pervasive and widespread, people from low-income, racialized, and Indigenous communities face a far greater risk of exposure. At …

In the handbook for demolition work only comprised small portion of demolition waste management. It is important to study and determine the ways to provide a practical guide for the professional in the building industry about handling the demolition waste. In general, demolition defined as tearing down or wrecking of structural work or architectural work of the building and other infrastructures work such as road, bridge and etc. It’s a common misconception that demolition is nothing more than taking down a structure and carrying the debris …


Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell Dec 2014

Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell

Howard Casey Cromwell

Polychlorinated biphenyl (PCB) is a persistent organic pollutant known to induce diverse molecular and behavioral alterations. Effects of PCB exposure could be transmitted to future generations via changes in behavior and gene expression. Previous work has shown that PCB-exposure can alter social behavior. The present study extends this work by examining a possible molecular mechanism for these changes. Pregnant rats (Sprague-Dawley) were exposed through diet to a combination of non-coplanar (PCB 47 - 2,20,4,40-tetrachlorobiphenyl) and coplanar (PCB 77 - 3,30,4,40- tetrachlorobiphenyl) congeners. Maternal care behaviors were examined by evaluating the rate and quality of nest building on the last 4 …

Under the US Environmental Protection Agency (EPA) High Production Volume (HPV) Challenge Programme, chemical companies have volunteered to conduct screening-level toxicity tests on approximately 2800 widely-used industrial chemicals. Participating companies are committed to providing available toxicity information to the EPA and presenting testing proposals for review by the EPA and posting on the EPA Web site as public information. People for the Ethical Treatment of Animals (PETA) and a coalition of animal protection organisations have reviewed all the test plans submitted by the participating chemical companies for compliance with the original HPV framework, as well as with animal welfare guidelines …


Engaging Communities To Identify And Address Environmental Health Literacy Gaps, Anna G. Hoover Nov 2014

Engaging Communities To Identify And Address Environmental Health Literacy Gaps, Anna G. Hoover

Anna G. Hoover

Frequently, decisions about the informational components and delivery mechanisms required to promote effective environmental health literacy are made by such technical experts as toxicologists, chemists, and communication scientists. However, because sensemaking processes are both retrospective and collective, context must be a central component for understanding the particular information needs of communities and stakeholder groups. Individual assessments of and tolerance for environmental health risks are rooted in past and present experiences that are understood, refined, and reinforced through dialogue with others who have shared similar experiences. Thus, the promotion of environmental health literacy requires formative engagement with communities and stakeholders to …


Lead Exposure From Aluminum Cookware In Cameroon, Jeffrey D. Weidenhamer, Peter A. Lobunski, Gilbert Kuepouo, Rebecca W. Corbin, Perry Gottesfeld Oct 2014

Lead Exposure From Aluminum Cookware In Cameroon, Jeffrey D. Weidenhamer, Peter A. Lobunski, Gilbert Kuepouo, Rebecca W. Corbin, Perry Gottesfeld

Jeffrey D. Weidenhamer

Blood lead levels have decreased following the removal of lead from gasoline in most of the world. However, numerous recent studies provide evidence that elevated blood lead levels persist in many low and middle-income countries around the world at much higher prevalence than in the more developed countries. One potential source of lead exposure that has not been widely investigated is the leaching of lead from artisanal aluminum cookware, which is commonly used in the developing world. Twenty-nine samples of aluminum cookware and utensils manufactured by local artisans in Cameroon were collected and analyzed for their potential to release lead …

Connecting Through Consilience: Ecology, Society, Culture And Technology, Ruth Mirams, Alexander Hayes

Alexander Hayes Mr.

Amongst linguistic, cultural and geographic diversity, humanity is characterised by inquisitiveness, communication and a deep desire to connect with each other. Despite our advanced intelligence and technological capacity, we are creatures of nature - a species which occupies a habitat, depends on consumable resources and fragile in many ways. As a species, we currently face challenges including overpopulation, diminishing resources and habitat degradation. In essence, we are exhausting the resources we depend on. [1] Resource depletion, disruption, famine, growth and sustainability are all observable in other species and natural systems. Human societies and systems can be described through the same …

20 Things You Can Do To Conserve Energy In 2015, Lissa Coffey Feb 2014

20 Things You Can Do To Conserve Energy In 2015, Lissa Coffey

LissaCoffey

Energy is lost when air conditioners and hot-air furnaces have to work harder to draw air through dirty filters. Cleaning/replacing a dirty air conditioner filter can save 5 percent of the energy used. That could save 175 pounds of CO2.air filters can save your company up to 30% of your total HVAC energy spend and last twice as long as traditional air filters. Also your company will benefit from significantly reduced installation labor costs and waste disposal costs. In the average commercial building, 50% of the energy bill is for the HVAC system and 30% of that is directly related …


Imagining Possibilities For Healthy Appalachian Communities In An Emerging Postindustrial Landscape, Brian Hoey Jan 2014

Imagining Possibilities For Healthy Appalachian Communities In An Emerging Postindustrial Landscape, Brian Hoey

Brian A. Hoey, Ph.D.

This paper explores how community might be re-imagined to promote incipient social and economic agendas born increasingly of broad-minded citizen initiatives within the Appalachian region aimed at what is generally understood as “development,” but of a form distinct from the prevailing models of a more industrial age. I would like to ask whether a city like Huntington, West Virginia can emerge as a progressive example of what we might term postindustrial, urban regeneration and perhaps what we might call community healing—specifically through grassroots movement now finding local governmental support in collective attempts to transform this place from one defined primarily …


Transmission Of Ranavirus Between Ectothermic Vertebrate Hosts, R Brenes, Matt J. Gray, T B. Waltzek, Rebecca P. Wilkes, Debra L. Miller Jan 2014

Transmission Of Ranavirus Between Ectothermic Vertebrate Hosts, R Brenes, Matt J. Gray, T B. Waltzek, Rebecca P. Wilkes, Debra L. Miller

Debra L Miller

Transmission is an essential process that contributes to the survival of pathogens. Ranaviruses are known to infect different classes of lower vertebrates including amphibians, fishes and reptiles. Differences in the likelihood of infection among ectothermic vertebrate hosts could explain the successful yearlong persistence of ranaviruses in aquatic environments. The goal of this study was to determine if transmission of a Frog Virus 3 (FV3)-like ranavirus was possible among three species from different ectothermic vertebrate classes: Cope's gray treefrog (Hyla chrysoscelis) larvae, mosquito fish (Gambusia affinis), and red-eared slider (Trachemys scripta elegans). We housed individuals previously exposed to the FV3-like ranavirus …

Could You Repeat That Please? Forty-Five Years Of Testing Pesticides On People, Barbara R. Leiterman Esq. Jan 2013

Could You Repeat That Please? Forty-Five Years Of Testing Pesticides On People, Barbara R. Leiterman Esq.

Barbara R. Leiterman Esq.

Little has been published in the literature about pesticide experiments conducted on human subjects. Yet there were at least twenty-two tests between 1967 and 2011 in which people were intentionally exposed to specific doses of pesticides. Almost all of these experiments violated scientific ethics and human rights. This article aims to describe those tests and their shortcomings, and explore the laws and regulations that incentivize such human experimentation. Ironically, as the public desire for pesticide safety increases, so does the industry’s motivation to test pesticides on people. Bringing these pesticide experiments to light, expanding the public discourse on the subject …
