A guided-inquiry lab, suitable for first-year general chemistry or high school advanced placement chemistry, is presented that uses only inexpensive, store-bought materials. The reaction of sodium bicarbonate (baking soda) with aqueous acetic acid (vinegar), under the constraint of the challenge to completely fill a sealable plastic bag with the…

The inexpensive and disposable electrode based on a double-polymer-modified pencil lead is proposed for upper-division undergraduate instrumental laboratories to enable the highly sensitive detection of perchlorate. Students fabricate and utilize their own electrodes in the 3-4 h laboratory session to learn important concepts and methods of…

Chemical flame-retardants are used in a variety of products to prevent the spread and occurrence of fire. While fire safety is critical, this family of chemicals, known as Polybrominated diphenyl ethers (PBDEs) are highly toxic. They are found in carpeting, foam cushions, polyester clothing and bedding, wallpaper, toys, household dust, a variety…

In the past century, the threats to children's health have shifted radically. Life-threatening infectious diseases--smallpox, polio, and cholera--have been largely conquered. But children are growing up in a world in which environmental toxins are ubiquitous. Measurable levels of hundreds of man-made chemicals are routinely found in the bodies of…

Healthy school environments are essential to ensure the best setting for learning. When school environments are unhealthy, students and staff may be exposed to harmful pollutants and chemicals that can cause their health, attendance, and scholastic performance to suffer. Among the factors that can affect the environmental quality of school indoor…

Informal science educators play a key role in promoting science literacy, safety, and health by teaching pesticide toxicology to the large, at-risk Latino farmworker population in the United States (US). To understand the experiences of informal science educators and the nature of farmworker education, we must have knowledge of farmworker…

The article describes the founding principles, work program, and accomplishments of a Reference Group with both expert and layperson stakeholders for the corrosion of copper canisters in a proposed deep repository in Sweden for spent nuclear fuel. The article sets the Reference Group as a participatory effort within a broader context of…

Understanding human environmental health is difficult for high school students, as is the process of scientific investigation. This module provides a framework to address both concerns through an inquiry-based approach using a hypothesis-driven set of experiments that draws upon a real-life concern, environmental exposures to lead (Pb2+). Students…

This article is an excerpt from "Raising Elijah: Protecting Our Children in an Age of Environmental Crisis" (2011), by Sandra Steingraber. As a scientist, mother, and concerned citizen, Steingraber explores herein the damaging effects of the myriad and ubiquitous environmental pollutants--in homes, schools, and communities--on the lives…

As one reads about the history of humans, he/she sees very early on that humans are naturally "tool users." More specifically, humans used tools as a means of subsistence and survival. Even today humans use tools to extend their capabilities beyond imagination. These tools are even used as weapons. However primitive, these early weapons would soon…

Having severe Asthma and trying to maintain a social life isn't easy, but when one adds the disability of Multiple Chemical Sensitivity (MCS) to the combination, the challenges become even tougher. As a dancer with both Asthma and MCS, the author was forced to give up the sport for 15 years before finding a group of line dancers that were…

Environmentally preferable products, sustainability, "green," reducing environmental footprint--have all become part of the everyday lexicon as schools, businesses, households, and the public sector have increasingly focused on strategies and tactics designed to reduce their impact on the environment and human health. State governments…

When one considers the necessary elements of a green cleaning program, it is tough to know where to begin. After all, green cleaning has evolved considerably from the days when a program simply involved using a couple of "green" chemicals. Over the last several years, successful green cleaning programs have grown in sophistication and are now…

Bill Thompson, Director of Facilities for Lockport Township High School in Illinois, first considered starting a green cleaning program after his janitors became dizzy when using a traditional chemical floor stripper. Thompson started introducing green products gradually at Lockport Township High, and now almost all of the cleaning agents used at…

The role of compliance assistance in the U.S. Environmental Protection Agency's overall enforcement strategy has been quite variable over the past decade and a half, increasing in prominence under the Bush administration and now slated for significantly reduced funding under the Obama administration. While theoretical models and anecdotal evidence…
