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.

The idea of redeveloping brownfields is not a new one, but linking this to occupational health disparities and community access to jobs is. The NIEHS Minority Worker Training Program (MWTP) holistically addresses one of the most significant problems with urban unemployment--workers lacking crucial technical job skills and experience, who are most vulnerable to occupational exposures and often lack access to healthcare. Find out how this program is making a difference in health disparities and environmental justice—AND the economy.

Article Abstract

The study described in this article evaluated surface survivability of culturable Pseudomonas aeruginosa by time and type (glass, stainless steel, and laminate) using two sampling techniques: contact plates and surface swabs. Recovery of P. aeruginosa decreased logarithmically over time and varied by surface type. P. aeruginosa survival averaged 3.75, 5.75, and 6.75 hours on laminate, glass, and stainless steel, respectively. Culturable P. aeruginosa loss on stainless steel and glass were not different (p > .05); however, laminate had significantly greater loss at each time point than either glass or stainless (p < .05). A comparison of surface swab and contact plate collection efficiencies found no significant difference for laminate surfaces. Swabs, however, had a higher collection efficiency than contact plates (p < .05).

For the first time, the authors report P. aeruginosa mean survival time of 3.75–6.75 hours on clinically relevant surfaces, with P. aeruginosa on stainless steel surviving the longest. Their data also indicate that culturable surface sampling appears to most accurately represent actual P. aeruginosa surface loading when swab sampling is used.

Article Abstract

Extensive literature has already documented the deleterious effects of heavy metal toxins on the human brain and nervous system. These toxins, however, represent only a fraction of the environmental hazards that may pose harm to cognitive ability in humans. Lead and mercury exposure, air pollution, and organic compounds all have the potential to damage brain functioning yet remain understudied. In order to provide comprehensive and effective public health and health care initiatives for prevention and treatment, we must first fully understand the potential risks, mechanisms of action, and outcomes surrounding exposure to these elements in the context of neurocognitive ability. This article provides a review of the negative effects on cognitive ability of these lesser-studied environmental toxins, with an emphasis on delineating effects observed in child versus adult populations. Possible differential effects across sociodemographic populations (e.g., urban versus rural residents; ethnic minorities) are discussed as important contributors to risk assessment and the development of prevention measures. The public health and clinical implications are significant and offer ample opportunities for clinicians and researchers to help combat this growing problem.

Book: Essentials of Environmental Health (Second Edition)Essentials of Environmental Health (Second Edition) provides a clear and comprehensive study of the major topics in environmental health.

Environmental threats are occurring on a worldwide scale. Dramatic pictures showing the devastating effects of natural disasters lead the nightly news. Stories of oil spills, contaminated groundwater, deforestation, and depleted fisheries appear in the pages of newspapers daily.

National and international policymakers are concerned about the potential impact on the health of the world’s population and, as a result, much progress has been made in informing the public and introducing regulations with the hopes of containing these hazards.

January 2010: a 7.0 earthquake hit Haiti, destroying its capital of Port-au-Prince, killing over 200,000 people. The recovery is ongoing. Tent camps were dismantled as citizens went back to some kind of home. But nearly 150,000 people still live in the shanty structures erected post disaster. Basic sanitation is a daily struggle. This talk will address the tragic reintroduction of cholera, share the ad hoc approaches to sanitation in Haiti, and the role EH professionals MUST play in disaster situations.
