Abstract

Ultrafine particles (UFPs) are ubiquitous in urban air and have been recognized as a risk to human health. The aim of this study was to measure the relationships among ultrafine particles and other ambient air pollutants and meteorological factors in the Tampa Bay Area. This study measured continuous UFPs, black carbon, oxides of nitrogen (NOx), nitrogen dioxide (NO2), nitric oxide (NO), carbon monoxide (CO), ozone (O3), sulfur dioxide (SO2), particulate matter having an aerodynamic diameter of 10 microns or less (PM10), relative humidity, wind speed, and ambient temperature during January to March 2014. Moreover, the study compared the relationship between UFPs and various co-pollutants daily, including during morning rush hour periods. This study found a moderate correlation among UFPs and black carbon, NOx, NO2, and NO during hourly continuous measurements and rush hour periods, and a low level of correlation among UFPs and CO, O3, SO2,PM10, relative humidity, wind speed, and ambient temperature. This study indicates that co-pollutants should not be used as a surrogate to assess the human health risk from ultrafine particles exposure.

Article Abstract

Asthma is a substantial public health burden among children. Disease and risk-factor discrepancies have been identified between racial, ethnic, and socioeconomic groups. At a rural health clinic (Salud) with primarily underserved and Latino patients in Colorado, the authors evaluated 250 medical records and administered 57 parental surveys to describe this population with respect to asthma diagnosis, asthma-like symptoms, and environmental/occupational risk factors among children. Wheeze and asthma were indicated in 9.7% and 8.9% of medical records, respectively. Twenty parents (35.7%) reported in a questionnaire that their child had experienced wheezing or whistling in the chest. Parents reported that children play in farming fields (21.8%) and feed livestock/animals (10.9%). Additionally, 13.2% and 9.4% of children have a household member who works around livestock or around grain, feed, or dust, respectively. Information from the Salud population can be used to develop larger-scale research and public health initiatives to eliminate health and risk factor disparities among underserved children.

Abstract

Some African-American communities in the U.S. South are excluded from nearby municipal water and sewer services and therefore rely on private wells and septic systems. These “underbounded” communities are disproportionately exposed to water contaminants and face elevated risks for poor health outcomes. Outreach efforts encouraging proper well testing and maintenance are needed to protect health in these communities. To identify knowledge gaps and misconceptions that such outreach programs should target, we conducted semistructured interviews with 18 residents of such communities in Wake County, North Carolina. Only one interviewee conducted annual well testing as recommended by the county health department. Interview results suggest that testing is inhibited by lack of awareness of well maintenance guidelines, overreliance on sensory information, poor understanding of exposure pathways, and cost. Links between private septic systems, well water contamination, and health are poorly understood, hindering proper septic maintenance. These findings highlight the need for risk communication materials targeting at-risk communities.

Abstract

Most populations now derive benefits as well as risks from a global economy. Local environnmetal health can be impacted positively through importation or adoption of foreign technological advances, administrative approaches, and cultural attributes, to name only a few. Similarly, risks are now commonly shared on an international scale, as illustrated by cross-border food source contamination, emerging or recognized disease spread, unchecked international pollution, and a host of other incidents in recent years. Beyond the case study, historical record of the textbook approach, affordable study abroad programs now exist to more concretely educate students about such impacts. Once considered simply a perquisite for more financially able students, or a requirement for language arts students, both short- and long-term study abroad programs increasingly add a necessary global perspective to the college environmental health graduate. This special report details the ways in which a number of accredited programs are using and integrating study abroad experiences into their curriculums to better prepare their graduates to meet the international environmental health and safety challenges of the 21st century.

Abstract

Rats are a common problem in cities worldwide. Impoverished urban neighborhoods are disproportionately affected because factors associated with poverty promote rat infestations and rat–human contact. In public health, most studies have focused on disease transmission, but little is known about the nonphysical consequences of this environmental exposure. Mental health often is neglected but is receiving increasing attention in public health research and practice. The objective of this study was to use a systematic review and narrative synthesis of the published literature to explore the effect of rat exposure on mental health among residents in impoverished urban neighborhoods. Although the literature addressing this topic was sparse, the results of this review suggest that rat exposure consistently has a negative impact on mental health. These effects can be elicited directly (e.g., fear of rat bites) or indirectly (e.g., feeling of disempowerment from inability to tackle rat problems). By developing a better understanding of potential rat-related health risks, both mental and physical, public health officials can better evaluate, refine, and develop their policies regarding rats.

Because military sites may be a potential source of heavy metal species runoff and more stringent water quality standards set in the Energy Independence and Security Act of 2007, a study is underway on the Fort Bragg campus to 1) determine the origin, fate, and relative abundances of heavy metal species in stormwater and 2) understand bioretention's role in sequestering many pollutants, including heavy metals, and the effect of an experimental media on this sequestration process. During this session, we will discuss the study and explore the importance of tailoring Best Management Practices (BMP) design to meet water quality goals and the implications this has on ecological systems.
