Diné citizen science: Phytoremediation of uranium and arsenic in the Navajo Nation.

Mid-20th century mining in Naabeehó Bináhásdzo (Navajo Nation) polluted soil and groundwater with uranium and arsenic. The Diné and other indigenous residents of this region use groundwater for drinking, livestock, and irrigation, creating a serious environmental health risk. Currently, many individuals and communities on the Navajo Nation must purchase and transport treated water from hours away.

Does diisocyanate exposure result in neurotoxicity?

Context: Diisocyanates have been associated with respiratory and dermal sensitization. Limited number of case reports, and a few case studies, media, and other references suggest potential neurotoxic effects from exposures to toluene diisocyanate (TDI), 1,6 hexamethylene diisocyanate (HDI), and methylene diisocyanate (MDI). However, a systematic review of the literature evaluating the causal association on humans does not exist to support this alleged association.

A comparison of traditional handwashing training with active handwashing training in the food handler industry.

The Centers for Disease Control and Prevention (CDC) have stated that poor personal hygiene is the third most commonly reported food preparation practice contributing to foodborne disease and h further claimed that contaminated hands may be the most important means by which enteric viruses are transmitted. The study reported here compared the effectiveness of traditional (lecture/video) training with that of traditional training that provided an added active (hands-on) component for the retention of handwashing procedures two weeks after the initial training. Sixty-six food handlers attending training courses were included in the study.
