  • 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 ...

  • In addition to formaldehyde, decoration, what harmful gases?

    As the saying goes, clothes can make people more beautiful, in fact, the house is the same, when you buy a house, and give it a beautiful coat, can improve the quality of life, living in the house for a long time, re decoration, the old house and get a new life. However, the decoration pollution problem has become a lot of people's heart disease. Today we are going to talk about the ...

  • 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 ...

  • 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 ...

  • 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, ...

  • 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 ...

  • Prop 65 Puts Acetaldehyde under the Spotlight

    Garden Grove, CA, May 5th, 2011 In 1986, California voters approved an initiative to address increasing concerns about exposure to toxic chemicals. That initiative, the Safe Drinking Water and Toxic Enforcement Act of 1986, is better known by its original name of Proposition 65.  Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the ...

  • Evaluation of mixing zones in a Latvian–Lithuanian transboundary river basin

    The neighbouring countries of Latvia and Lithuania should use common water assessment methodologies and measures for water management in the transboundary rivers according to EU Water Framework Directive, establishing a framework for community action in the field of water policy. However, there are no national and local legislative acts describing how to harmonise water policy and activities ...
