As part of NEHA's continuos effort to provide convenient access to information and resources, we have gathered together for you the links in this section. Our mission is "to advance the environmental health and protection professional for the purpose of providing a healthful environment for all,” as well as to educate and inform those outside the profession.

Abstract

Recruitment of participants into any community-based project can be a significant challenge, particularly for Lead Hazard Control and Healthy Homes grantees funded by the U.S. Department of Housing and Urban Development. One of these grantees, the 2013–2016 Henderson Lead Hazard Control and Healthy Homes Program, implemented six recruitment strategies: 1) person-to-person referrals, 2) direct mail, 3) door-to-door neighborhood canvassing, 4) child-oriented community event outreach, 5) passive program information, and 6) general event outreach. Program staff reached more than 10,000 individuals via these methods, and 136 participants ultimately were enrolled. The success of each method was determined by its percentage yield of enrolled participants. Community event outreach resulted in the greatest number of contacts, while person-to-person referrals and direct mailings yielded the most enrolled participants with minimal staff time required. Landlords were essential to the enrollment of rental units. These results might help provide insight to some of the most effective strategies for recruitment into Lead Hazard Control and Healthy Homes programs.

Abstract

Landscaping and groundskeeping workers are exposed to excessive amounts of loud noise from powered lawn equipment and tools that can lead to adverse health effects, including noise-induced hearing loss. The main objectives of this project were to evaluate attitudes and behavior of wearing hearing protection devices (HPDs) and to test the effectiveness of knowledge following an educational training among these workers. This was a cross-sectional intervention study. Bivariate analysis was conducted to evaluate worker perceptions about the importance and frequency of wearing HPDs. Pre- and post-tests were distributed to workers to evaluate significant differences in learned knowledge following a multifaceted noise and hearing loss training. Although nearly all workers recognized the importance of wearing either earplugs or earmuffs, actual use for wearing HPDs was approximately only half of the time when working around loud noise. Following the training intervention, there was a significant increase between mean pre- and post-test scores. Targeted trainings can be effective for increasing worker knowledge about the effects of noise, hearing loss, and hearing protection. Sustained efforts, however, must be made by employers to ensure that regular trainings are routinely provided and that the use of HPDs are promoted in the workplace.

Article Abstract

The authors conducted a survey of small streams to evaluate the effects of centralized and onsite wastewater treatment on the occurrence of selected traditional and emerging contaminants in small streams in the upper Neuse River basin, North Carolina. An undeveloped site was included to assess effects of residential land use activities on stream quality. Concentrations of nutrients and ions were higher in samples from streams in residential sites than from the stream in an undeveloped area. Overall, streams draining residential areas showed relatively small differences with respect to type of wastewater treatment. Two sites, however—one in an area of centralized wastewater treatment apparently near a suspected sewer line leak, and the second in an area of onsite wastewater treatment—showed effects of wastewater. Organic wastewater compounds were detected more frequently in samples from these two sites than from the other sites. Optical brighteners levels were correlated (r2 = .88) with the number of organic wastewater and pharmaceutical compounds detected at the residential sites and could potentially serve as a screening method to assess wastewater effects on small streams.

Abstract

Private wells are unregulated and often at risk for arsenic contamination. Research objectives included distribution of groundwater arsenic concentrations, identification of arsenic sources, and establishment of best practices for well construction to minimize risk for wells in Cerro Gordo County, Iowa. We sampled 68 wells over 3 years with 393 water samples and 79 rock samples. Geochemical modeling was used to better understand arsenic mobilization. Arsenic in groundwater ranged from 1.0 to less than 10.0 μg/L for 75 water samples and 31 water samples had arsenic concentrations greater than or equal to 10 μg/L. The arsenic source is naturally occurring sulfide minerals (typically pyrite) in the bedrock aquifers. The shallow (100–150 feet) Lime Creek Aquifer was most at risk for arsenic. Arsenic is likely mobilized from the rock into the water in the shallow aquifer under more oxidizing conditions, subject to water level changes. The study resulted in a policy change for arsenic testing and well completion in Cerro Gordo County to better protect domestic well users.

Abstract

Public health interventions in North Carolina were implemented only for children with blood lead levels (BLLs) ≥10 µg/dL until the end of the year in 2017, although the Centers for Disease Control and Prevention (CDC) established 5 µg/dL as a revised reference value for identifying children with elevated BLLs in 2012. This study quantified and characterized the children with elevated BLLs in Buncombe County, North Carolina. A review of case reports of Buncombe County children was conducted through the North Carolina Lead Surveillance System online database. In all, 23 children had confirmed elevated BLLs (≥10 µg/dL) from 2005–2015, while 146 children had BLLs within 5 to <10 µg/dL from 2012–2015. Most of the identified children (62%) lived in Asheville and were 1–2 years old (65%). A significant number of children will be aided and prevented from further lead exposure since North Carolina has lowered the BLL intervention standard to the CDC reference value in 2012. The need for additional staffing at local health departments has been identified to adapt to such change.

Emergency Public Health provides a unique and practical framework for disaster response planning at local, state, and national levels. This is the first book of its kind to systematically address the issues in a range of environmental public health emergencies brought on by natural calamity, terrorism, industrial accident, or infectious disease. It features historical perspectives on a public health crisis, an analysis of preparedness, and a practical, relevant case study on the emergency response. Study reference for NEHA’s REHS/RS exam.

Pharmaceuticals are emerging contaminants in water and, to date, cannot be removed as part of wastewater treatment options. So what can be done to mitigate their effects upon the environment, yet maintain their efficacy for human and animal use? In this session, we examine this topic from a lifecycle approach using hands-on demonstrations, and discuss several solutions and policies you can take home to mitigate and address these contaminants in your community.

What type of consumer products do you interact with on a daily basis and do they contain nano-particles? What properties might those engineered iron, titanium and carbon nano-particles exhibit that differ from the norm? What type of information do environmental health professionals need to prevent exposures that might cause negative biological effects? This session will give you the facts so you can adapt to the rapidly changing intersection of health and environment.
