  • The possible toxic effects of lead

    Lead is a chemical element in the periodic table that has the symbol Pb (Latin: plumbum) and atomic number 82. A soft, heavy, toxic and malleable lead is bluish white when freshly cut but tarnishes to dull gray when exposed to air, very dense metal which is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is odourless. It is highly resistant to corrosion ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...

  • Stocking Your Green Building Toolkit

    1. Introduction Designing, constructing and operating environmentally friendly buildings can be a lot more complex than it seems, especially when it comes to materials selection. We would all like simple measures or rules of thumb that would make the selection process easy, but they are hard to come by, if they exist at all. The reality is that we are constantly forced into a balancing act, ...

  • Toxicity reduction in industrial and municipal effluents – the state of the art

    Developments in treatment technology have traditionally focused on removal of specific contaminants: BOD, solids, ammonia, TOC and lately, specific organics such as phenol. A limit on effluent toxicity, however, does not fit so neatly into a procedural package, since it truly integrates the presence and impacts of contaminants in a sample. Toxicity reduction evaluation procedures, therefore, are ...

  • How can lead be so crucial, but also so toxic?

    Why is everyone talking about lead? Not long ago, like so many historic buildings in the UK, a local parish church near to where I live had the lead stolen from its roof.  Sadly, this is not so unusual and all the more distressing in this case, both because it holds special memories as the church where my wife and I were married, and also because the lead was stolen during heavy ...

  • The environmental pyramid: a new way to deal with solid toxic waste

    Our society produces large volumes of solid waste, including toxic chemical waste. For toxic solids, the current disposal practice is to dump them into isolated, lined pits, and cover them with a water-impermeable layer with a soil layer on top. Such waste deposits require 'eternal' control and monitoring, because they eventually do leak, contaminating the surrounding soil and groundwater. Here, ...

  • Bird proofing hangars, parks and government buildings

    Bird Proofing government buildings, parks, military bases, and aircraft hangars has been a problem for quite some time. At the dawn of aviation, the Wright brothers recorded a bird strike that interfered with their early flights. More recently, Hanscom Field in Bedford Massachusetts had roughly 5,000 starlings roosting in their hangar. Clinton Air Force Base in Oklahoma had six hangars with ...

  • Compost integral in new website in building soil

    A website called “BuildingSoil” has been launched by the Washington Organic Recycling Council to help builders preserve healthy soil on building sites. It's the latest Soils for Salmon project which aims to change standard site development practices. These new “soil best management practices” will soon be required by local governments around western Washington, as they update local codes to ...

  • Facility siting changes for process plant buildings in the works

    Facility siting identifies hazards that may affect process plant buildings, assesses the potential consequences and leads to the development of a means to manage the risks of these hazards. In short, it is a procedure to make sure process building siting (location, construction and function) is appropriate based on the known hazards (toxic, fire andexplosion) at the facility.Past incidents at ...

  • Toxicity Identification Evaluation (TIE) as a Tool for Water Quality Management

    Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. Over 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system. While ...

  • PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia

    In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn ...

  • FTIR meets Fire Testing needs for toxic gas analysis - Case study

    One of the most dangerous aspects of a fire is the toxic gases that can arise from the process of combustion. To save lives and develop safer materials for airplanes, trains, and buildings, it is vital to identify and measure the gases that are released when products and materials are burning. The BASF Fire Technology Laboratory in Ludwigshafen, Germany, conducts fire testing on materials to ...

  • EPA mercury rules: Keeping the lights on while removing toxics from our air

    Next week the U.S. Environmental Protection Agency is expected to finalize new rules to reduce mercury and other toxic air emissions that will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will new EPA ...

  • The Toxic Effects of Hydrogen Sulfide (H2S) Gas from Sewers on Health & Infrastructure - Case study

    How is Hydrogen Sulfide Created? Hydrogen sulfide emitted from sewers and septic tanks can cause serious health issues. Hydrogen sulfide gas is created and released into the air when waste water remains stagnant for a long period of time, and becomes depleted of dissolved oxygen. Although sewer workers are most likely to be affected by hydrogen sulfide overexposure, people living or ...

  • FRACKING: Freeing Energy Resources versus Polluting the Earth and Public Health with Radiation and Toxic Chemicals?

    Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil. The wastewater, brine, and sludge are then returned to the surface and in need of disposal. Unfortunately there is not yet a clear and safe method of disposal or storage. Among these chemicals ...

  • To build a sustainable world, academics need to tear down the Ivory Tower

    Avoiding societal collapse means building bridges between science and the rest of the world. Until recently, Earth was so big compared with humanity’s impacts that its resources seemed limitless. But that is no longer the case. Thanks to rapid growth in both human population and per capita consumption, we are now on the edge of irrevocable damage to our planetary life ...
