Issues and topics related to educational challenges in toxicology at all levels are discussed. They include public awareness and understanding, general approach to toxicology, quality structure-activity relationships, epidemiological studies, quantification of risk, and the types of toxicants studied. (JN)

National Academy of Sciences report, "Pesticides in the Diets of Infants and Children," recommends that legal limits of pesticide residues in food should be health-based standards with adequate safety margins for all consumers, including infants and children. Tolerances currently reflect "good agricultural practice." Children…

Topics addressed in this discussion of toxicology and chemical safety include routes of exposure, dose/response relationships, action of toxic substances, and effects of exposure to chemicals. Specific examples are used to illustrate the principles discussed. Suggests prudence in handling any chemicals, whether or not toxicity is known. (JN)

Emphasizing that for any known teratogen no safe dosage level exists, this case-illustrated review identifies the bases for current concern about the pollution of the environment, reflects on the promise and complexities of the emerging disciplines of behavioral toxicology and behavioral teratology, and describes existing evidence of teratogenic…

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)

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)

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)

Notes that neurobehavioral problems from exposure to lead and other toxins can be observed at doses far below those that cause more obvious signs of exposure. Calls for refining tests of cognitive and developmental skills in exposed children, identifying additional contaminants and mechanisms for behavioral effects, and improving dose- repose…

Discusses the growing awareness of potential toxicological effects of synthetic organic chemicals contaminating groundwater. Problems concerning pesticides, chlorination, epidemiologic studies, cancer, nephrotoxicity, and considerations of risk are addressed. Additional research in this area is advocated. (DH)

Discusses the nature of toxic substances, examining pesticides and herbicides, heavy metals, industrial chemicals, and household substances. Includes a list of major toxic substances (indicating what they are, where they are found, and health concerns) and a student activity on how pesticides enter the food chain. (JN)

Discusses environmental hazards, the problems of misinformation and contradictory information, and the problems for children in sorting out fact from hearsay. Includes tips for protecting children from environmental hazards and describes a program at the University of Washington that develops curriculum materials and other teacher resources. (PVD)

This curriculum consists of a one-week course of study designed to introduce K-3 students to (or increase their awareness of) toxic substances commonly found in the home. It includes an introduction/conceptual framework and four learning activities for four concept areas (and an optional word puzzle). Each activity includes a statement of purpose,…
