  • Analysis of Formaldehyde simple and sensitive method for analyzing free formaldehyde

    Formaldehyde is used for disinfections of industrially manufactured products. However, it is detrimental to health and its potential oncogenicity led to the current utilization of a formaldehyde donor for long-term preservation. Such donors are in hydrolytic equilibrium with formaldehyde producing free formaldehyde on exposure to moisture. This method is used to quantify the free formaldehyde ...

  • Pt. 2 - IN the MIX - Construction Safety and Gas Detection

    This is part 2 of our 4 part series on Gas detection in the Construction Industry. With so many OSHA regulations, where do we begin to search for help with gas detection or respiratory protection within confined spaces? To start, OSHA has a web tool called the OSHA Construction “eTool”. ...


  • Fixed multi-parameter gas detection system can ensure industrial facilities are safe from hazardous or toxic gases

    Industrial workplaces are likely to come across one or more hazardous or toxic gases. Combustible gases such as methane are highly dangerous because they can cause large and fatal explosions when ignited. Other problem areas when working in industry are carbon monoxide (which poisons the cardiovascular system), oxygen deficiency, and elevated levels of other gases and pollutants, depending and ...

  • Remote sensing of particular pollution from space: Have we reached the promised land?

    The recent literature on satellite remote sensing of air quality is reviewed. 2009 is the 50th anniversary of the first satellite atmospheric observations. For the first 40 of those years, atmospheric composition measurements, meteorology, and atmospheric structure and dynamics dominated the missions launched. Since 1995, 42 instruments relevant to air quality measurements have been put into ...

  • Disinfection of tertiary wastewater effluent prior to river discharge using peracetic acid; treatment efficiency and results on by-products formed in full scale tests

    This is an investigation of chemical disinfection, with peracetic acid (PAA), in a tertiary sand filter at a full scale activated sludge plant with nitrification/denitrification and P-removal. The reduction efficiency of Escherichia coli and intestinal enterococci in the sand filter is reported. E. coli log reductions of between 0.4 and 2.2 were found with ...

  • Pollution survey of carbonyl compounds in train air

    The train is an important vehicle in China, but its air quality has important impacts on passengers’ health. In this work, pollution from carbonyl compounds was measured in the air of six trains. The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers. The ...

  • Determination of toxic heavy metals in sea water by FAAS after preconcentration with a novel chelating resin

    A solid phase extraction procedure was developed for preconcentration of toxic heavy metals such as cadmium, cobalt, copper, manganese, lead and zinc in sea water samples. A microcolumn packed with 6-[(4-hydroxyphenyl)diazenyl]naphthalene-2,3-diol-formaldehyde (HPDN-F) resin acts as a sorbent to retain the analyte ions by forming metal chelates. The retained trace level metal was subsequently ...

  • Negative differential resistance in carbon–silica nanocomposites

    In this work, carbon–silica nanocomposites have been elaborated by sol–gel technique. SiO2 nanoparticles were mixed with resorcinol–formaldehyde (RF) carbon precursor solution with RF/SiO2 mass ratio being 1. The samples were dried by increasing temperature from ambient to 150°C by step 10°C/day and then pyrolysis at several temperatures ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • `Green Buildings` can create problems with IAQ

    The recent trend towards energy conservation measures have in some cases led to airtight building construction that can often create problems with Indoor Air Quality (IAQ). Some 'green buildings' (also known as ‘green construction’ and ‘sustainable buildings’) have ignored the issue of IAQ in pursuit of energy saving measures. Ventilation systems are set to minimize the ...
