  • Real-Time Measurement of Outdoor Tobacco Smoke Particles

    ABSTRACT The current lack of empirical data on outdoor tobacco smoke (OTS) levels impedes OTS exposure and risk assessments.  We sought to measure peak ...

  • Analyzer underpins growth of container inspection company

    After a career as a customs officer in the Netherlands, Wim van Tienen was well aware of the toxic gas hazards presented by some freight containers, so in 2009 he started a company, Van Tienen Milieuadvies B.V., offering gas analysis and safety advice. The company grew quickly and now employs 23 staff. Wim attributes a large part of this success to the advanced FTIR gas detection and analysis ...

  • Tire Shredding: The Best Alternative

    From cars and trucks to planes, tractors, and forklifts, tires are used for a wide variety of vehicles. And those tires don’t last forever. Regardless of how many miles a tire travels, it should not be used longer than ten years past its manufacture date, as the rubber will grow brittle and can crack. This isn’t usually a problem, though, since most tires are replaced within three or ...

  • LED Applications for Oil and Gas Refining and Processing

    Oil and gas processing facilities are unsafe due to the existence of hazardous compounds during operations. When addressing such issues, companies in the sector may deploy explosion proof lighting systems to prevent the ignition of sparks created from the electrical equipment. The adoption of LED technology in oil and gas refineries has helped reinforce key safety measures associated with ...

  • Stop It Pipe Repair System assists in decommissioning project - Case Study

    Since 1986, InduMar Products Inc. has provided a unique solution with its STOP IT Pipe Repair System. In refineries and chemical plants, where many miles of piping carry products that are often highly flammable, toxic or corrosive, the STOP IT provides a method to restore product and profit flow in minutes instead of the many hours required to cut out a pipe section, fabricate and install a new ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • It is time for changes in the analysis of whole effluent toxicity data

    The whole effluent toxicity (WET) program in the United States, Canada, and other countries typically requires multi concentration testing of effluents. While multiconcentration testing of chemicals is desirable for regulatory and scientific reasons, we believe this requirement is not as efficient for evaluating effluent compliance in a WET program. The key regulatory question of concern is ...

  • 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 ...

  • A real-time, rapid emergency control model for sudden water pollution accidents in long-distance water transfer projects

    A real-time, rapid emergency control (EC) model is proposed to cope with sudden water pollution accidents in long-distance water transfer projects. The EC model outputs the method of EC based on pollutant properties. A generalized form of EC model is proposed and tested with a demonstrative project. The rapid prediction formulas of emergency control parameters (ECPs) are proposed under ...

  • Toxicity Testing Moves Ahead

    Lynn L. Bergeson, “toxicity testing moves ahead,” chemical processing, September 2010. The Tox21 Partnership aims for far faster and less expensive screening. Who would have thought that an automated laboratory working around the clock could screen chemical substances for interactions with biological targets at speeds mere mortals could hardly consider — let alone match? Well, ...

  • Mohawk Laboratories has acquired Strathtox providing greatly improved `real-time` studies

    Mohawk Laboratories, the research and development arm of NCH Corporation, has acquired Strathkelvin’s latest respirometer, StrathtoxTM, resulting in greatly improved ‘real-time’ bioremediation potential efficacy studies for its BioAmp system. This allows NCH to provide quick study results to its customers and potential customers in determining whether or not the bacteria ...

  • Continuous Real Time Water Monitoring for Radiation Safety Terrorist Attack, Improper Disposal of Industrial Waste, Accidental Discharge

    Safe drinking water is essential to life on earth. Unfortunately, this vast infrastructure suffers from critical vulnerability. Keeping America safe with continuous real time water monitoring is a vital goal and is currently being addressed for biological and chemical risks. For monitoring of radionuclides in drinking water as recommended in the Safe Drinking Water Act 8, the Clean Water Act 9, ...

  • The importance of experimental time when assessing the effect of temperature on toxicity in poikilotherms

    Temperature is an important factor affecting toxicity, determining chemical toxicokinetics and toxicodynamics in poikilothermic organisms. As also metabolic rates are affected by temperature, interactions between the emergence of toxic effects and time are very likely. The aim of this study was to investigate how temperature affected the toxicity of copper towards the nematode Caenorhabditis ...

  • AquaFinesse USA_Aquatic Toxicity Test Results.

    The recommended dose rate for Cool Puck is one 53gram puck for 20.000 L of water, wich translates to a theoretical maximum dose rate of 2.65 mg/L. All of the above (see page 2 PDF- schedule) toxicity results are greater than the recommended dose rate. C. dubia was the most sensitive organism to the product, with an acute effects level approximately 16-fold above the product's recommended dose ...

  • Toxicity Assessment Using a Dilution Series

    Toxicity, or more appropriately, inhibition, is a measure of the interference of a compound or compounds with biodegradation. Since inhibition usually is expressed as the interference with bioconversion of an oxygen-consuming reaction – or gas producing reaction in the case of anoxic or anaerobic reactions – it is essential that a biodegradable substrate be present when assessing toxicity of ...

  • Toxic formaldehyde very common in homes

    EMSL Analytical provides formaldehyde testing solutions for industry and the public. Formaldehyde can be found in most homes across the country. The chemical is commonly used to manufacture numerous building materials and household items. The most significant source of formaldehyde in most homes is from pressed wood products made with formaldehyde containing adhesives. According to the EPA, “High ...


  • Indigenous people fight toxics in Arctic

    The fourth meeting of the United Nations Environment Programme’s Conference of the Parties of the Stockholm Convention on Persistent Organic Pollutants opened today in Geneva, Switzerland to discuss restricting and phasing out the world’s most dangerous chemicals. Representatives from Indigenous communities of the Arctic greeted the delegates with drumming and traditional songs to remind them of ...

  • First toxicity data of chlorophenols on marine alga Dunaliella tertiolecta: Correlation of marine algal toxicity with hydrophobicity and interspecies toxicity relationships

    The toxicity of phenol and 13 chlorinated phenols to the marine alga Dunaliella tertiolecta is presented for the first time. The newly generated marine algal toxicity data was found to correlate strongly with the widely used hydrophobicity parameter—the logarithm of the n‐octanol–water partition coefficient (log KOW). Interspecies relationships using the new marine algal toxicity data of ...
