  • A Citizen`s Guide to Chemical Dehalogenation

    What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they ...

  • Are mining waste disasters inevitable?

    On 5 November 2015 the dam of an iron ore tailings management facility in Bento Rodrigues, Brazil, suffered a catastrophic failure and flooded the area. The immediate consequences were dire: the accident killed at least 11 people, injured over a dozen more and left more than 500 people homeless. However, this is just the start: the environmental impact of the Bento Rodrigues dam disaster, with ...

  • Hazard material information management and regulatory compliance

    Prior to the 1970s, legislative acts addressing hazardous chemicals were few in number and specific to a handful of topics. The Refuse Act of 1899 was often ignored and rarely enforced, and the Atomic Energy Act of 1954 was exclusive to radioactive material. When it came to workplace and community safety involving the handling, storage, disposal, and transportation of hazardous materials, ...

  • What is Chemical Oxygen Demand (COD)?

    Chemical Oxygen Demand (COD) analysis is a measurement of the oxygen-depletion capacity of a water sample contaminated with organic waste matter. Specifically, it measures the equivalent amount of oxygen required to chemically oxidize organic compounds in water. Why Measure COD? COD is used as a general indicator of water quality and is an integral part of all water quality ...

  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • Toxins Found in E-Waste

    One of the worst effects of a skyrocketing, global e-waste crisis is the risk of toxic contamination for the environment and communities. In fact, delving into the many chemical and heavy metal materials that make up most electronic devices, it seems that toxins and electronics go hand in hand. Though many manufacturers of electronic devices are finding innovative ways to work around toxins found ...

  • Principles of Waste Avoidance and Utilization

    The minimization of wastes requiring disposal is increasingly important as available disposal options become more and more constrained, and particularly as more substances enter everyday use which are not readily decomposed in the natural environment and which can present long term hazards. This note sets out some basic principles for waste minimization in industrial processes, where ...

  • The search for water contamination can create hazards of its own

    It''s a paradox. Most of the very technologies being used today to test water for contaminants actually return more pollution to the environment than the tested water itself. Nevertheless, as we all know, water testing is crucial to our health. Modern industry has unleashed tens of thousands of chemicals into the environment. Many of these chemicals are essential, but it''s the control of them ...
