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)

Examined is the development of resistance and secondary pest outbreaks and disease vectors. Two examples are considered in depth. A list of 42 references is included. (CW)

Background information is provided on the registered trademark "TLV" (Threshold Limit Value), the term used to express tolerable concentrations. The TLV of a compound is an estimate extrapolated from some defined damage to humans or animals at higher concentrations or by drawing analogies between similar concentrations. (JN)

An inspection of 138 New Jersey school buildings revealed that a significant percentage of school officials do not have a good understanding of their asbestos management plan and, therefore, are failing to meet all of the Asbestos Hazard Emergency Response Act's requirements. (MLF)

Discusses the role of dissection in science courses, examining essential lessons students can learn (such as developing an abiding respect for all forms of life, including the animal being dissected). Also presents a list of tips related to classroom dissection and comments on formaldehyde and formalin substitutes. (JN)

Alerts readers to a number of health hazards associated with products and processes commonly used in art classes. Describes current concerns, outlines steps to be taken to protect teachers and students, lists toxic substances that can be found in art materials, and suggests alternative materials that can be used. (PGD)

Presents a pamphlet and four brochures about pesticide hazards, pesticide use and alternatives, special impacts on children, lawn and garden pest management, and pesticides in food. Discusses the whys and ways of using these materials to inform people about pesticide issues. (MDH)

Discusses the relative instability of organic oxidants, citing early attempts at overcoming the solubility limitations in organic reaction systems. Describes the more recent introduction of new types of organic oxidant salts that have demonstrated more promising levels of stability, though unexpected explosions have still occurred. (TW)

Presents a sample contract for disposing of hazardous wastes in an environmentally sound, timely manner in accordance with all federal, state, and local requirements. Addresses situations where hazardous waste must be disposed of outside the laboratory and where alternate disposal methods are not feasible. (JN)

Presents a scenario related to the disposal of potentially dangerous ether. Several suggestions for dealing with peroxide-forming compounds are included. (JN)

Procedures for recovering silver and cobalt from laboratory wastes (including those resulting from student experiments) are presented. The procedures are generally applicable since only common, inexpensive laboratory reagents are needed. (JN)

Hazardous waste management is a continual process. Administrators should maintain good relations with state agencies and the Environmental Protection Agency and use them as resources. Contacts with businesses and professional groups as well as forming coalitions with neighboring districts are ways to share information and expenses. (MLF)

Provides a framework that incorporates the diverse elements of risk management in science education into a systematic process and is adaptable to changing circumstances. Appendix contains risk management checklist for management, laboratory and storage, extreme biological and chemical hazards, protective equipment, waste disposal, electrical…

Presents a model, ChemSafe, that was developed to address and solve the allied problems of chemical purchase, storage, use, and disposal in schools. (ZWH)

A public entity facing an environmental cleanup can take certain measures to dramatically increase its chance of coverage. Argues that many comprehensive general-liability insurance policies have coverage if the pollution is "sudden and accidental." (MLF)
