  • 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 ...

  • 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 ...

  • Formaldehyde and Aromatic Volatile Hydrocarbons in the Indoor Air of Egyptian Office Buildings

    Indoor and outdoor measurements of formaldehyde and the aromatic hydrocarbons: benzene, toluene, ethylbenzene, m,p-xylene and o-xylene (BTEX) were conducted at six offices in a suburban area in Giza, Egypt, during the winter 2003-04 season. The mean indoor level of formaldehyde was 59.79ppb in offices where there was no smoking and 85.01ppb in offices where people smoked. The highest mean level ...

  • Policy influence of formaldehyde exposure risk in air-conditioned office environment

    Long-term measurement of indoor air quality (IAQ) over a general community could be a good approach to evaluate the influence of policy on pollutant exposure levels. However, this approach requires considerable measurement efforts and in many circumstances an updated data set will not be available. Formaldehyde is an indoor pollutant that presents a health hazard to building occupants in the long ...

  • 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 ...

  • 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. ...

  • German Environmental Survey IV: environmental tobacco smoke exposure of German children

    As the current extent of Environmental Tobacco Smoke (ETS) exposure of children in Germany is unknown, it was investigated in the German Environmental Survey (GerES IV) for Children from 2003 to 2006 using questionnaires and analyses of cotinine in urine and benzene and formaldehyde in indoor air. About half of the 3- to 14-year-old children in Germany live in households with at least one smoker. ...
