Some simple chemistry is used to demonstrate how Fe(II) ions, formed during iron corrosion in acid aqueous solution, can reduce toxic Cr(VI) species, forming soluble Cr(III) and Fe(III) ions. These ions, in turn, can be precipitated by neutralizing the solution. The procedure provides a treatment for industrial wastewaters commonly found in…

College and university science programs generate hazardous waste that must be dealt with and disposed of in accordance with state and federal regulations. During a recent renovation and addition project for the State University of New York at Plattsburgh (SUNY Plattsburg), the author was contracted to analyze existing regulations, research best…

The use of silver in commercial products has proliferated in recent years owing to its antibacterial properties. Food containers impregnated with micro-sized silver promise long food life, but there is some concern because silver can leach out of the plastic and into the stored food. This laboratory experiment gives students the opportunity to…

Abstract Context: Limited research suggests that translational approaches are needed to decrease the distance, physical and cultural, between farmers and health care. Purpose: This study seeks to identify special concerns of farmers in Alabama and explore the need for a medical education program tailored to prepare physicians to address those…

There is a considerable body of literature on research on environmental knowledge, attitude and action. A lot of research has occurred on the primary and secondary school populations and the general population. However, much less emphasis has been placed on studies that concern post-compulsory education students in the range from 16 to 18 years…

Introducing students to the process of scientific inquiry is a major goal of high school and college labs. Environmental toxins are of great concern and public interest. Modifications of a vertebrate developmental toxicity assay using the frog Xenopus laevis can support student-initiated toxicology experiments that are relevant to humans. Teams of…

An electrochemical experiment is presented to illustrate biosorption to second-year and upper-division undergraduate students. The extraction of Cd[superscript 2+], Pb[superscript 2+], and Cu[superscript 2+] by nonliving "Typha latifolia" (cattail) roots can be monitored in real time by potentiometry determinations. The open circuit potential…

This year's Federal Interagency Forum on Child and Family Statistics' (Forum) report provides the Nation with carefully selected key national indicators of children's well-being and monitors changes in these indicators. The purposes of this report are to improve reporting of Federal data on children and families; make the most relevant data on the…

An experiment exploring the photochemical properties of quinones was developed. Their unique photochemistry and highly reactive nature make them an ideal class of compounds for examining structure-activity relationships. For several substituted quinones, photochemical reactivity was related to structure and ultimately to the Gibbs energy for…

The theoretical basis of reactive oxygen species and their impact on health issues are relatively easy to understand by biomedical students. The detection of reactive oxygen species requires expensive equipment, the procedures are time consuming and costly, and the results are hard to interpret. Moreover, cause-and-effect relationships in the…

This project involved developing a method to remediate large quantities of aqueous waste from a general chemistry laboratory experiment. Aqueous Ni(II) waste from a general chemistry laboratory experiment was converted into solid nickel hydroxide hydrate with a substantial decrease in waste volume. The remediation method was developed for a…

E-waste contains hazardous chemicals and materials that threaten the environment and human health, when improperly disposed. This study examined levels of awareness of e-waste disposal among university students in Ghana, and their proenvironmental decision-making using two outcome variables: "knowledge on environmental impact and policy…

Operation Cleansweep is a free pesticide disposal program that has operated in Florida since 1995. The program is open to commercial facilities, including agricultural production establishments, golf course operators, and pest control companies. Since its inception, the program has had more than 1,700 participants and collected more than 1,000,000…

Many education institutions have embraced the growing push for sustainable design and have built environmentally friendly facilities that use resources more efficiently. But the plaudits that administrators receive for LEED certification and other recognition of their efforts may be meaningless if the green commitment ends when a building is…

This activity is designed to provide students with an overview of environmental health and to encourage them to think critically about how they can minimize their potential negative health impacts from environmental exposures. Objectives: Students will (a) define environmental health, (b) analyze media wherein environmental health issues are…
