Risk communication on the health effects of radon encounters many challenges and requires a variety of risk communication strategies and approaches. The concern over radon exposure and its health effects may vary according to people’s level of knowledge and receptivity. Homeowners in radon-prone areas are usually more informed and have greater concern over those not living in radon-prone areas. The latter group is often found to be resistant to testing. In British Columbia as well as many other parts of the country, some homes have been lying outside of the radon-prone areas have radon levels above the Canadian guideline, which is the reason Health Canada recommends that all homes should be tested.

Over the last five years, the Environment Health Program (EHP) of Health Canada in the British Columbia region has been using a variety of different approaches in their radon risk communications through social media, workshops, webinars, public forums, poster contests, radon distribution maps, public inquiries, tradeshows and conference events, and partnership with different jurisdictions and nongovernmental organizations. The valuable lessons learned from these approaches are discussed in this special report.

Article Abstract

In the study discussed in this article, 27 private drinking water wells located in a rural Colorado mountain community were sampled for radon contamination and compared against (a) the U.S. Environmental Protection Agency’s (U.S. EPA’s) proposed maximum contaminant level (MCL), (b) the U.S. EPA proposed alternate maximum contaminate level (AMCL), and (c) the average radon level measured in the local municipal drinking water system. The data from the authors’ study found that 100% of the wells within the study population had radon levels in excess of the U.S. EPA MCL, 37% were in excess of the U.S. EPA AMCL, and 100% of wells had radon levels greater than that found in the local municipal drinking water system. Radon contamination in one well was found to be 715 times greater than the U.S. EPA MCL, 54 times greater than the U.S. EPA AMLC, and 36,983 times greater than that found in the local municipal drinking water system. According to the research data and the reviewed literature, the results indicate that this population has a unique and elevated contamination profile and suggest that radon-contaminated drinking water from private wells can present a significant public health concern.

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 Recreational Water PowerPoint is available via the link listed below:

Repeated warnings by the scientific community on the dire consequences of climate change through global warming to the ecology and sustenance of our planet have not been give appropriate attention by the U.S. public. Research has shown that climate change is responsible for catastrophic weather occurrences--such as floods, tornadoes, hurricanes, and heat waves--resulting in environmental and public health issues. The purpose of this report is to examine factors influencing public views on climate change. Theoretical and political perspectives are examined to unpack opinions held by the public in the U.S. on climate change. The Health Belief Model is used as an example to showcase the efficacy of an individual behavior change program in providing the synergy to understand climate change at the microlevel. The concept of reframing is discussed as a strategy to alter how the public views climate change.

A re-emergence of bedbugs and resultant impacts on community resources led to the convening of a “Bedbug Summit." Attendees represented professionals from a broad spectrum of affected sectors including housing providers, homeless-shelters, education, pest control services, public health, waste stream management, and social services. During the summit, this group worked together and identified collaborative approaches to address bedbugs in the region. The resulting Bed Bug Workgroup has made significant achievements including successful advocacy for additional funding, launching an information telephone hotline, developing a multi-lingual educational clearinghouse website, and identification of a collaborative surveillance system that protects pest control operators and the communities they serve. Attend this session to learn about how engaging nontraditional partners results in more robust environmental health outcomes and apply a community organizing model to emergent public health issues.

Article Abstract

Infants and young children under five years of age are uniquely vulnerable to certain environmental contaminants. Some of these contaminants have been found in early learning environments (ELEs), or child care and family child care settings where children spend an average of 40 hours a week. These contaminants as well as infants’ and children’s unique physiology, exposures, and behaviors in child care settings are the focus of this article. Current child care and family child care licensing requirements specific to environmental health–related issues are also reviewed. Data were reviewed and analyzed from the following surveys: the 2008 Child Care Licensing Survey, the First National Environmental Health Survey of Child Care Centers, and the Children’s Total Exposure to Persistent Pesticides and Other Persistent Organic Pollutants. The authors’ analysis suggests that current state licensing programs impose only the most basic environmental health protection requirements. No mandatory federal regulations standardize child care and family child care regulatory efforts nationally. Resources are available, however, from federal agencies and other children’s environmental health organizations that may provide guidance for how to establish better environmental health protection measures in ELEs.

Biological hazards such as exposure to ticks and mosquitoes can affect health. Permethrin-treated clothing is available to the public. We don’t currently understand, however, the effects of environmental factors such as fabric type, washing, sunlight, and temperature on permethrin content in treated clothing with respect to mosquito knockdown and mortality. We evaluated the extent to which fabric type (100% cotton denim jeans, 100% polyester work shirt, 35% cotton/65% polyester work shirt), light exposure (0 or 100%), temperature (18 °C, 32 °C), and number of washes (0, 3, 12, 36) affected mosquito knockdown 2 hours post-exposure, mosquito mortality 24 hours post-exposure, and permethrin content. All fabrics used in this study were treated with permethrin at a concentration of 125 µg/cm2. Denim fabric having no washes and no light exposure showed the highest amount of permethrin. Washing and light exposure significantly reduced the ability of permethrin-treated fabrics to induce mosquito knockdown and/or mortality under the simulated conditions used for this test. Temperatures tested did not affect permethrin content or mosquito knockdown and mortality. Long-lasting impregnation of uniforms protects against mosquito bites under simulated laboratory conditions. Employers and employees should consider the use of permethrin-impregnated clothing and uniforms in addition to daily repellent sprays.
