Summarizes findings from the Agency for Toxic Substances and Disease Registry concerning the evaluation of data about hazardous substance release into the environment. Identifies the hazardous substances, exposure, health effects, and public health impact from 951 facilities identified on the National Priorities List (NPL) by the Environmental…

Cites incidents of toxic indoor air and hazardous material in and around school buildings. (MLF)

An extension project sold 4,000 radon kits; 46% were returned for testing and 23% of homes were at risk. Interviews with 100 of those at risk found that only 41% believed they had a problem; women and college graduates were more likely than men and high school graduates to believe it. Of those who believed they had a problem, only 63% took any…

Discusses hazardous waste, waste disposal, unsafe exposure, movement of hazardous waste, and the Superfund clean-up process that consists of site discovery, site assessment, clean-up method selection, site clean up, and site maintenance. Argues that proper disposal of hazardous waste is everybody's responsibility. (JRH)

Introduces Chemical Laboratory Information Profiles (CLIPs) which can be used to assist in making precaution decisions for laboratory work. Lists hazardous chemicals that have a popular use among students. (YDS)

A mixture of potassium hydroxide and alpha-naphthaldehyde (1) are heated under solvent-free conditions to produce 1-naphthoic acid (2) and 1-naphthalenemethanol (3). The experiment offers several advantages over many existing exercises including the ease of reaction workup, shorter reaction time, relative environmental friendliness of the…

The consequences of broken mercury-in-glass thermometers in academic laboratories results in various health and environmental hazards, which needs to be replaced, by long-stem digital thermometers and non-mercury glass thermometers. The factors that should be considered during the mercury replacement process are types of applications in the…

Industrial application of gas chromatography-mass spectrometry (GC-MS) analysis is a powerful technique that could be used to elucidate components of a complex mixture while offering the benefits of high-precision quantitative analysis. The natural wintergreen oil is examined for its phenol concentration to determine the level of refining…

The 20th anniversary of the Bhopal calamity fell on December 3, 2004. The world's worst industrial disaster in Bhopal, India, happened because of inadequate maintenance by Union Carbide and poor monitoring by the Indian authorities. Malfunctioning safety measures, inappropriate location of the plant, and lack of information about the identity and…

Previous studies have established that community residents and leaders differ in their support for hazardous waste facility siting in rural areas (Spies et al. 1998). We examine whether these same differences exist in rural communities that face other high-risk development decisions by analyzing resident and leader support for a proposed gold…

There is a growing concern about the connection between many chemical exposures and learning and other developmental disabilities (LDD). National and local groups are developing new programs around the country that are making this connection--and taking action with regard to policy, education and research efforts. They are working towards reducing…

Five days a week, more than 55 million children, teachers and employees spend the majority of their waking hours in the U.S. school buildings. Besides being exposed to science, history and math, children and teachers are exposed to hundreds if not thousands of potentially hazardous chemicals and pollutants. Because children spend so much time in…

This publication presents changes and modifications for 2007-2008 to the "International Rules for Precollege Science Research: Guidelines for Science and Engineering Fairs." It is written to guide fair directors, teachers, scientists, parents, and adult volunteers as they pursue their work of encouraging students to explore and investigate their…

This paper reports on a study of pupils' knowledge and understanding of atmospheric pollution. Specifically, the study is aimed at identifying: 1) the extent to which pupils conceptualise the term "air pollution" in a scientifically appropriate way; 2) pupils' knowledge of air pollution sources and air pollutants; and 3) pupils'…

The Accelerated Reduction/Elimination of Toxins (ARET) Challenge was a voluntary program initiated in 1994 by the Government of Canada. Unlike the U.S. 33/50 Program, ARET involved industry partners in negotiation and cosponsorship of the program, with the intention that early involvement would yield stronger commitment to voluntary reductions. We…
