  • NILU measures formaldehyde in Northern Italy

    NILU participates in the second FORMAT campaign, which will take place in Northern Italy during the period 8 September to 5 October 2003. Several scientists from NILU will be staying in the area around Milan to measure formaldehyde (HCHO) and test instruments to improve measurement techniques. NILU is using a DOAS ...

  • 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 ...


  • Formaldehyde problems for FEMA and many others

    There has been concern about the release of formaldehyde gas from construction material used in the trailer homes used by FEMA for temporary housing.  Why the concern over formaldehyde?  Formaldehyde is a gas at normal temperatures.  It is the simplest member of a class of organic chemicals called “aldehydes.”  Most common aldehydes, including formaldehyde, have a ...

  • Alternative Analysis of Formaldehyde-DNPH and Other Carbonyl-DNPH Derivatives by Capillary GC

    Alternative Analysis of Formaldehyde-DNPH and Other Carbonyl-DNPH Derivatives by Capillary GC -  GC analysis of 15 carbonyl-DNPH compounds has some advantages over the HPLC analyses described in US EPA and other environmental methods.  Determination of formaldehyde and 14 other carbonyls in air according to US Environmental Protection Agency Method TO11  and American Society for ...

  • Dangers of Formaldehyde used as adhesive in manufacture of wood-based panel products.

    Formaldehyde is a chemical widely used to manufacture building materials and various household products.  Wood based panels can emit small amounts of formaldehyde to the air and each panel type has a product standard governing the testing and certification of that product for formaldehyde emissions. Anyone involved in the manufacture of these products could be exposed to formaldehyde in ...

  • Determination of formaldehyde content in toys using UV/Vis Spectrometry

    As product safety regulations for industry are becoming stricter, more testing at lower levels is required for toxic elements or hazardous organic chemicals such as formaldehyde in children’s toys/clothing. Formaldehyde resins are used in fabrics to bind pigments to the cloth, as a fire retardant and to provide stiffness. In cotton and cottonblend fabrics they are used to enhance wrinkle ...

  • Nuclear Industry Testing of PetroZorb Application

    The article describes application of PetroZorb microporous sorbent for application to the removal and disposal of radioactive liquids in the nuclear industry.  The material removes the presence of liquid, enabling the waste to be transported as a solid, and reduces the radioactive vapors to an acceptable level. Previous to this ...

  • Gas turbine compliance emissions test case study

    CKwas retained by Lake Road Generating Company, LP (Lake Road) to conduct a compliance emissions test program on three combustion turbine and heat recovery steam generators (CT/HRSG). The purpose of this program is to demonstrate that emissions from the CT/HRSGs are within the emission limits specified in the operating permit issued by the Connecticut Department of Environmental Protection ...

  • 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 ...

  • Suitable solid state chemical sensor for HCHO determination

    A solid state NiO-polyaniline mixture electrode is proposed and characterised to determine formaldehyde. The influence of ionic strength is particularly significant. The response is slow, so a waiting time, optimised at 90 min is needed, thus preventing a continuous or in-flow condition determination. Some common environmental possible interfering analytes have been tested, the most interfering ...

  • Superplastic deformation of solid wood by slipping cells at sub–micrometer intercellular layers

    In order to facilitate the generation of a flow phenomenon due to the slipping of wood cells under a specific temperature condition, a phenol formaldehyde resin of low molecular weight was introduced into wood cells. The effects of the existence of phenol formaldehyde molecules in wood cells on the flow behaviour of solid wood were investigated experimentally by means of a free compression test. ...

  • Development of biomarkers in an integrated approach to environmental studies

    This study was conducted in a contained environment in order to develop biomarkers and to evaluate the environmental damage after a release of two different toxic substances which are widely used in industrial production. In a simulation study performed in Tor Mancina area (near Rome, Italy), two dangerous substances (formaldehyde and bromine) were tested. Chemical and physical characterisation, ...

  • Effect of three fungicides on in vitro growth of Fusarium solani and Fusarium semitectum, parasitic on Odontesthes bonariensis eggs

    An in vitro evaluation of the effect of three fungicides on the growth rate (GR) of Fusarium solani and Fusarium semitectum was performed. The tested fungicides, commonly used in fish farming, were sodium chloride (NaCl), methanol-stabilised formaldehyde (F) and malachite green (MG). Both Fusarium species were isolated from eggs of the Argentinean pejerrey Odontesthes bonariensis (Valenciennes, ...

  • Study of constructed wetlands effluent disinfected with ozone

    The purpose of this research was to study the disinfection of sanitary effluent from constructed wetlands, evaluating the oxidation of organic matter, the formation of formaldehyde, as well as the efficiency of total coliforms and Escherichia coli inactivation. A constant flow of ozone was applied to the batch system in 5 and 10 mg.O3 L−1 doses with contact times ...
