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.

Article Abstract

Handheld temperature and relative humidity (T/RH) meters are commonly used in residential indoor air surveys. Although popular, T/RH meters are prone to sensor drift and consequent loss of accuracy, and thus instrument manufacturers often recommend annual calibration and adjustment. Field-use conditions, however, have been shown to accelerate electronic sensor drift in outdoor applications, resulting in out-of-tolerance measurements in less than one year. In the study described in this article, sensor drift was evaluated under residential field use for 30 handheld T/RH meters to predict needed calibration intervals based on hierarchical linear modeling. Instruments were used in 43 home visits over a 93-day period and were calibrated (without adjustment) 49 times over the study period with a laboratory standard. Analysis of covariance showed significant drift among temperature sensors for all three instrument types (p < .0001) and among humidity sensors in two instruments. The authors’ study suggests calibration frequency should be based on instrument performance under specific sampling conditions rather than on predetermined time intervals.

This session will include a brief overview of IPM and provide tools and resources needed to develop and implement an IPM program. After the session, environmental health professionals will be able to explain the key elements of an IPM program, including the roles and responsibilities of key players. You will be able to identify the health, environmental, and economic risks posed by pests and the pesticides, and the benefits of IPM in particularly sensitive environments like schools, daycares, and hospitals.

Abstract

Industrial emissions, deteriorating or improperly removed lead paint, and the use of lead additives in fuel have left a substantial burden of heavy metals, such as lead, in urban soils. Much of this lead remains near the surface where it has the potential to impact human health. Exposure to lead, especially in children, can have lasting impacts on neurological development and academic achievement. Urban gardening, in particular, is an activity that could result in increased exposure to soil lead for many unsuspecting gardeners. During the summer of 2012, more than 1,061 surface soil samples were collected from an approximately 1.25 acre urban community garden in Terre Haute, Indiana. Samples were collected to evaluate the spatial distribution of lead across the community garden on the plot level. The results highlight the variability that can be seen within small areas of a former residential property, for example lead concentrations that are low (<200 parts per million [ppm]) within the same 10 x 10 foot garden plot as concentrations that are considered high (>600 ppm). Based on the results of this work, several areas of concern were identified and the community garden was reconfigured to reduce potential lead exposure to gardeners and the local community.

Hispanic farmworkers represent a vulnerable population that spends a large amount of their work shift exposed to UVR from the sun. This cross-sectional study included a sun safety behavior survey followed by a full body exam for skin cancers among Latino farmworkers (N=158). Farmworkers continue to experience high exposure to UVR while lacking sufficient information about risks of skin cancer. Additional studies for educating and reducing UVR exposure to this workgroup is warranted.

Chuck Lichon, R.S., M.P.H., Deputy Health Officer at District Health Department #2 in Michigan, developed a Children’s Environmental Health Power Point Program with the financial assistance of the Dow Chemical Company, Midland, MI.  The Power Points are approximately 25-35 minutes in length, allowing for a presentation to be made during one classroom setting, or to be used for a community presentation, allowing time for Q & A.  Some of the topics include: Sunwise, Body Art, Household Hazardous Waste, Meth, Recreational Water, and more.  They are free to download and use for presentations in your school, health department community presentations, or for media use.  Changes in the presentations should not be made without consent from the author, and/or the NEHA Board of Directors.  

The Sun Wise PowerPoint is available via the link listed below:

In 2015, the Maricopa County Environmental Services Department (MCESD) attended to over one million additional visitors to ensure their food safety and security at the Super Bowl. If that weren’t enough, there was also the Pro Bowl, Waste Management Open, and all associated events involving 3 major cities within a 2 week span! Find out what it takes to plan for this kind of large scale event, which agencies to partner with, and how to incorporate technology and social media to facilitate implementation.

The Model Aquatic Health Code is published, but many in industry and public health think that the code did not set the correct limits for cyanuric acid. Some believe it is too restrictive and others believe it is not restrictive enough. This presentation is intended to provide you with the information you need to join the debate in the Conference of the Model Aquatic Health Code to help provide reasonable limits for cyanuric acid that are protective of public health.
