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 Apr 2017

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 Apr 2016

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 …

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 …

Mary M. Lee

BACKGROUND: In animal studies, organochlorine pesticide (OCP) exposure alters pubertal development; however, epidemiological data are limited and inconsistent. OBJECTIVE: To evaluate the associations of serum OCP concentrations [hexachlorobenzene (HCB), beta-hexachlorocyclohexane (beta-HCH), and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE)] with male pubertal onset. METHODS: In Chapaevsk, Russia, a town environmentally contaminated with OCPs, 350 8-9 year old boys with measured OCPs were enrolled during 2003-2005 and were followed annually for eight years. We evaluated three measures of pubertal onset: testicular volume (TV) > 3 mL in either testis, or stage 2 or greater for genitalia (G2+), or pubic hair (P2+). We used multivariable interval-censored models to …


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 …

Connecting Through Consilience: Ecology, Society, Culture And Technology, Ruth Mirams, Alexander Hayes Jul 2014

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 …

Experimental Validation Of The Multiple-Zone System Ventilation Efficiency Equation Of Ansi/Ashrae Standard 62.1 (1276-Rp), David P. Yuill, Grenville K. Yuill, Andrew H. Coward May 2012

Experimental Validation Of The Multiple-Zone System Ventilation Efficiency Equation Of Ansi/Ashrae Standard 62.1 (1276-Rp), David P. Yuill, Grenville K. Yuill, Andrew H. Coward

David Yuill

This article describes an experiment that was carried out on an existing building to test the validity of the system ventilation efficiency equation for multiple-zone recirculating systems of ANSI/ASHRAE Standard 62.1. The system ventilation efficiency equation (SVEE) can be applied to buildings that use a recirculating air distribution system. It accounts for the fact that the return air carries some “unused” outdoor air, so that the amount of new outdoor air introduced at the air handler can be reduced. The SVEE is based on a mass balance but infiltration and interzonal mixing are not included in the formulation. Since infiltration …


Proteomic Analysis Of 17Β-Estradiol Degradation By Stenotrophomonas Maltophilia, Zhongtian Li May 2012

Proteomic Analysis Of 17Β-Estradiol Degradation By Stenotrophomonas Maltophilia, Zhongtian Li

Z Li

Microbial degradation plays a critical role in determining the environmental fate of steroid hormones, such as 17β-estradiol (E2). The molecular mechanisms governing the microbial transformation of E2 and its primary degradation intermediate, estrone (E1), are largely unknown. The objective of this study was to identify metabolism pathways that might be involved in microbial estrogen degradation. To achieve the objective, Stenotrophomonas maltophilia strain ZL1 was used as a model estrogen degrading bacterium and its protein expression level during E2/E1 degradation was studied using quantitative proteomics. During an E2 degradation experiment, strain ZL1 first converted E2 to E1 stoichiometrically. At 16 h …


Removing 17Β-Estradiol From Drinking Water In A Biologically Active Carbon (Bac) Reactor Modified From A Granular Activated Carbon (Gac) Reactor, Zhongtian Li Mar 2012

Removing 17Β-Estradiol From Drinking Water In A Biologically Active Carbon (Bac) Reactor Modified From A Granular Activated Carbon (Gac) Reactor, Zhongtian Li

Z Li

Estrogenic compounds in drinking water sources pose potential threats to human health. Treatment technologies are needed to effectively remove these compounds for the production of safe drinking water. In this study, GAC adsorption was first tested for its ability to remove a model estrogenic compound, 17β-estradiol (E2). Although GAC showed a relatively high adsorption capacity for E2 in isotherm experiments, it appeared to have a long mass transfer zone in a GAC column reactor, causing an early leakage of E2 in the effluent. With an influent E2 concentration of 20 μg/L, the GAC reactor was able to bring down effluent …
