The Force of Law: Increasingly Complexity of Environmental Problems
During the 1970s, environmental issues seemed straight-forward. Today, the increased number of chemicals that have been introduced into the environment are producing greater risks, and the complexity of the effects of those risks are better understo...
Occupational Safety and Health: Worker Safety in the Space and Science Industries
Propelled by the Cold War, research and testing of rocket motors and fuels flourished in the mid 1900s, exposing workers to the acute effects of toxic chemicals and the as yet unknown chronic and long term effects. Around the same time, experiments ...
Chemical Treatment Technologies: Oxidation and Reduction: An Overview
While some metals can be readily precipitated, others cannot be until they are reduced. The clarified water resulting from these processes can then be discharged into a municipal wastewater treatment system.
Chemical Treatment Technologies: Precipitation and Toxicity
The electroplating industry uses many chemicals in the process of plating objects like golf clubs and water faucets with metals such as chromium and copper. Before the chemically-laden water used in the electroplating process can be released into s...
Pollution Prevention: Bridging Troubled Water: Alternative Pulp and Paper Bleaching Technology
Facing a lawsuit charging it with discharging toxic effluent in the water off the coast of northern California, Louisiana Pacific knew it needed to change the way its pulp mills operated. Even though it successfully met the mandates of the lawsuit ...
Chemical Treatment Technologies: Benign by Design, Biomonitoring, and Enforcement
The future of chemical treatment technology is striving to attain the reduction of waste at its source, and seeking to improve the monitoring of that which is discharged.
Thermal Treatment Technologies: Risks and Rewards of Thermal Destruction
Thermal destruction of hazardous wastes has much potential, but it has aroused much public concern, as well. Even the best such techniques are only safe and effective when they are controlled and done properly--something that is not always the case.
Hazardous Materials: Hazardous Materials: Pesticides
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires that pesticides used in the United States be registered with the EPA before they can be distributed, sold, or used. Once registered, there are specific legal requirements to be...
Health Effects of Hazardous Materials: Case of Inappropriate Use of Methyl Parathion, A
The case of an unlicensed Chicago exterminator is investigated. Used appropriately, methyl parathion poses no danger. But Reuben Brown did not use it for its intended agricultural purposes. He used it inside people's homes, where it may not break d...
