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

Windborne fungal spores are able to move across international borders, which is a health issue because many fungi are pathogenic and can infect humans. Moreover, pathogens can shift their geographic range under climate change, infecting previously unexposed populations. We used a macrosystems approach to identify future research priorities related to windborne dispersal of fungal pathogens. We focused on the fungus Coccidioides, the causal agent for valley fever in humans. The geographic range of Coccidioides spp. includes the U.S.–Mexico border region, where cases of valley fever have increased. As Coccidioides does not adhere to international boundaries, we advocate for a binational approach to understand valley fever from a public health and ecological perspective. Knowledge gained from research on Coccidioides can be leveraged to other windborne fungal pathogens, especially those that have an environmental stage in their life cycle. Finally, we argue that air dispersal of Coccidioides should be a research priority in light of future climate challenges that will require informed science policy decisions.

Abstract

We investigated a gastrointestinal illness cluster among persons who attended a baseball tournament (>200 teams) during July 2015. We interviewed representatives of 19 teams; illness was reported among only the 9 (47%) teams that stayed at Hotel A (p < .01). We identified 55 primary cases. A case-control study demonstrated that pool exposure at Hotel A was significantly associated with illness (odds ratio: 7.3; 95% confidence interval: 3.6, 15.2). Eight out of nine (89%) stool specimens tested were positive for Cryptosporidium, with C. hominis IfA12G1 subtype identified in two specimens. The environmental health assessment detected a low free available chlorine level, and pool water tested positive for E. coli and total coliforms. A possible diarrheal contamination event, substantial hotel pool use, and use of cyanuric acid might have contributed to this outbreak and magnitude. Aquatic facilities practicing proper operation and maintenance (e.g., following the Centers for Disease Control and Prevention’s Model Aquatic Health Code) can protect the public’s health.

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 Crystal Meth PowerPoint is available via the link listed below:

Abstract

Unintentional nonfire-related (UNFR) carbon monoxide (CO) poisoning is among the leading causes of unintentional poisoning deaths in the U.S. Our objective was to determine risk factors for UNFR CO poisoning deaths during the cold season in New York City (NYC). We examined data from death certificates and NYC Office of Medical Examiner records to describe decedent demographics, exposure circumstances, and CO sources during the cold months (October–April) between 2005–2013. Over the study period there were 32 UNFR CO deaths, with an average annual death rate of 0.4 per million people. Average annual cold-season death rates were higher among older adults (1.2 per million people ≥65 years) and men (0.8 per million men). The most common source of exposure was automobile engines (n = 15, 47%). The UNFR CO poisoning death rate in NYC is lower than the national average. Older adults and men are at greatest risk of death. Automobile exhaust is a significant and preventable source of exposure and should be emphasized in public health messaging and prevention efforts.

Abstract

The large global production of plastics and their presence everywhere in society and the environment have created a need for assessing chemical hazards and risks associated with plastic products. Plastics from polystyrene can release potentially toxic products (including styrene), particularly when heated. In this study we used a Fluo-Imager Analyser with software for spectral fluorescence signature (SFS) analysis. The objective of this study was to evaluate and compare the amount of styrene released into food and beverages by using SFS on a Fluo-Imager Analyser. Our results showed that concentrations of released styrene were in the range of 1.45–9.95 µg/L for hot water and 0.10–2.78 µg/L for room temperature water. The results indicate that this fluorescence diagnostic method is an effective tool for analysis of styrene released into food and beverages from polystyrene containers and cups, and could be useful in further investigations of styrene toxicity.

Every day, thousands of shipments of toxic and radiological chemicals, traverse our highways and railways, as potential “agents of opportunity” for terrorists' use.  This informational session will describe:

 

  1. the public health threats due to Radiological and Chemical "Agents of Opportunity"
  2. the deficiencies in education and training of public health responders to these types of events, and
  3. the development and  relevance of a preparedness course called, "Radiological and Chemical Agents of Opportunity for Terrorism: The Emergency Medicine Response to Toxic Industrial Chemicals and Materials (TICs/TIMs) and Toxic Radiological Materials (TRMs)."
