"MCPS School Safety and Security at a Glance" provides, in a single document, information about the reporting of incidents related to school safety and security, school climate, local school safety program descriptions, and serious incidents in all Montgomery County (Maryland) public schools. The information is presented for each school.…

Data on the health of wildlife in the Great Lakes ecosystem are reviewed. Researchers infer from data on eight species that the effects in offspring are the result of exposure to chlorinated chemicals by adults and passed to the offspring via maternal transfer. Policy implications are discussed. (CW)

Several policy frameworks for managing hazardous waste import/export are examined with respect to economic issues, environmental sustainability, and administrative feasibility and effectiveness. Several recommendations for improving the present instrument and implementing process are offered. (Author/CW)

This compendium is a tool for bringing waste management education into classrooms. Curriculum materials gathered from across the country were reviewed by California's top environmental educators, both for correlation with the state's educational frameworks and for accuracy and completeness of waste management information. Materials that cover…

Summarizes the history of the study of global warming and includes a discussion of the role of gases, like carbon dioxide, methane, and chlorofluorocarbon (CFC). Discusses modern research on the global warming, including computer modelling and the super-greenhouse effect. (YP)

Discussed are accidents that occur in the laboratories of highly trained chemists. Four examples are provided to illustrate potential hazards that are often overlooked in chemistry laboratories, molten inorganic salt baths, the reaction of acetone and hydrogen peroxide, halogenated acetylene compounds, and the reaction of hydrogen peroxide and…

Discusses the use of the human health risk assessment model as a basis for developing ecological risk assessment (ERA). For ERA, risk to individuals is less important than the survival of the population, with the exception of endangered species. Suggests that ERA take into account the relative reproductive value of the potentially impacted…

How to access and search using the Online Library System (OLS) is described. The OLS is a computerized list of bibliographic citations compiled by the library network of the Environmental Protection Agency (EPA). It consists of several related databases and can be used by anyone to search for books, documents, journals, and other materials. In…

Land; exploitation of land; and changing Indian needs, attitudes, and religious demands define environmental issues facing modern Native Americans. Such issues are related to agriculture and ranching, forests and watersheds, hunting and fishing, water, natural resource mining and pollution, hazardous and radioactive waste storage, urbanization of…

The purpose of this qualitative research was to determine the ways that knowledge is constructed and used by emergent citizen's groups (ECGs are grassroots, action-oriented, problem-solving groups) engaged in environmental conflicts, and by a state government environmental regulatory agency that interfaced with them. Four…

Presented is an experiment in which students recover almost 90 percent of the original lead chloride thus saving on costs of chemicals and disposal. Included are experimental procedures and a discussion of typical results. (CW)

A survey of advertisements for personnel to manage toxic and hazardous substances was used to measure the demand for these persons in the workplace. Reported are the size of the current workforce and the expected growth in the number of new positions over a five-year period. (Author/CW)

A study explored Protection Motivation Theory (PMT) in the context of news reports about a hazard. Content elements of outcome severity, vulnerability, and response efficacy were systematically varied in stories about a fabricated risk: fluorescent lighting lowering student academic performance. Research subjects were 206 students in an…

Artificial intelligence (AI) is the field of scientific inquiry concerned with designing machine systems that can simulate human mental processes. The field draws upon theoretical constructs from a wide variety of disciplines, including mathematics, psychology, linguistics, neurophysiology, computer science, and electronic engineering. Some of the…
