The Environmental Inquiry program supports inquiry based, student-centered science teaching on selected topics in the environmental sciences. Many teachers are unfamiliar with both the underlying science of toxicology, and the process and importance of peer review in scientific method. The protocol and peer review process was tested with college…

Describes research activities and recent findings on disease-causing viruses, fungi, and bacteria. Includes a list of contemporary viruses and what they cause and lists of extra-classroom microbiology activities and student projects. (BC)

Public health is threatened by toxic wastes when recreational facilities are built over dump sites or abandoned industrial plants. This article discusses the problem of disposing hazardous wastes and how it affects unknowing children and adults. (DF)

Article tells the story of how a New York City customs man was bit by a King Cobra from Thailand and the medical treatment he received. Describes three types of snake venoms: hemotoxins, cytotoxins, and neurotoxins. Explains how horses are used to produce antitoxins and side effects of the antitoxins on humans. (PR)

Suggests that a literature survey can alert students to real-life ethical problems surrounding many organic compounds. Topic areas students could explore include: hazards in the workplace, toxic chemicals, and nerve gas structures. Background information and an extensive bibliography are given. (DH)

Draws conclusions on the scientific uncertainty surrounding most chemical use regulatory decisions, examining the evolution of law and science, benefit analysis, and improving information. Suggests: (1) rapid development of knowledge of chemical risks and (2) a regulatory system which is flexible to new scientific knowledge. (DH)

The sword-tailed horseshoe crab (Limulus polyphemus) has developed its own defense against bacteria surrounding it. This defense system, under the name "Limulus test," now provides medicine and hygiene with a valuable means of detecting bacterial endotoxins at extremely low levels. (Author/JN)

A Brooklyn College (New York) science course for nonmajors includes a unit on drugs and poisons using material from television news, investigative reporting, and fictional series. The films make some of the more abstract course material palatable and interesting, and enhances awareness of the hazards and benefits of chemicals. (MSE)

The cumulative result of almost 100 years of mining, milling, and smelting has left areas of Jasper County, Missouri, contaminated with high levels of the trace metals Pb, Cd, and Zn. The site was listed on the National Priorities List in 1990 and is now known as the Jasper County or Oronogo-Duenweg Mining Belt Superfund Site. The U.S.…

This guide comprises four reports on the Laboratory Animal Data Bank (LADB), the National Institute of Health Environmental Protection Agency (NIH/EPA) Chemical Information System (CIS), nonbibliographic databases for the social sciences, and the Toxicology Data Bank (TDB) and Registry of Toxic Effects of Chemical Substances (RTECS). The first…

Discusses use of 1,1,1-trichloroethane as a substitute for carbon tetrachloride. Provides information on additives to commercially supplied sources in relation to possible reaction interferences. Warns of toxicity and possible carcinogenic action. (JM)

Toxicology/chemical hazards, safety policy, legal responsibilities, adequacy of ventilation, chemical storage, evaluating experimental hazards, waste disposal, and laws governing chemical safety were among topics discussed in 10 papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). Several topics…

Physicians and other health professionals attended either a two-day voluntary (n=27) or one-day mandatory (n=23) conference on toxicology. Groups did not differ in pretest/posttest scores; two-day participants were significantly more satisfied. Both groups demonstrated significant knowledge gains. (SK)

Describes a microbial bioassay, using molds as test organisms, that demonstrates toxicities of environmental pollutants. Includes laboratory methods and applications for the experiment. (MDH)

Introduces the Environmental Inquiry (EI) program which focuses on five topics: watershed dynamics, environmental toxicology, ecology of invasive species, biodegradations, and urban ecosystem modeling. (YDS)
