  • 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 ...

  • What is the difference between a REL and a PEL?

    There is often confusion between exposure limits put out by different agencies even within the same administration. For example, here the National Institute for Occupational Safety and Health (NIOSH) establishes Recommended Exposure Limits (RELs) whereas the Occupational Safety and Health Administration (OSHA) issues Permissible Exposure Limits (PELs). Realizing the difference between the two is ...

  • Sampling of Carbonyls Using a Dual-Layer LpDNPH Glass Sampling Tube and HPLC Analysis

    The dual-layer LpDNPH sorbent tube is an air sampling device designed for sampling carbonyls (e.g. formaldehyde) in ambient, indoor, and industrial atmospheres. Carbonyls are trapped on our high-purity silica gel adsorbent coated with 2,4-dinitrophenylhydrazine (2,4-DNPH) where they are converted to stable hydrazone derivatives. The derivatives are eluted from the tube in acetonitrile and ...

  • 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 ...

  • High concentrations of Aldehydes can be found in the hospital environment

    Both Formaldehyde and Glutaraldehyde are found in the hospital environment at higher concentrations than those to which the general population is exposed. Their possible adverse health effects are therefore very important to those working in certain parts of hospitals and to patients whose health status may be compromised. Both compounds are irritants and can cause sensitisation. Glutaraldehyde ...

  • 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 ...

  • Preconcentration of Cu (II) from seawater using a novel and stable phenol–formaldehyde resin

    Preconcentration of Cu (II) from seawater using a novel phenol–formaldehyde (P–F) resin was investigated. 1,2-dihydroxybenzene-4-azo-3-hydroxybenzene-formaldehyde resin (DAHBF) was prepared by condensing 1,2-dihydroxybenzene-4-azo-3-hydroxybenzene with formaldehyde (1:2 mole ratio) in the presence of oxalic acid as catalyst. Polychelates were obtained when the DAHBF was treated with the aqueous ...

  • Formaldehyde – a dangerous chemical

    It’s amazing all the places that formaldehyde is found.  It’s best known uses are in insulating material and particleboard.  The most publicized use has been in manufactured homes and mobile homes.  FEMA has been overwhelmed with actions related to exposure to formaldehyde in temporary housing for Hurricane Katrina survivors, and other disasters. There are both short ...

  • 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 ...

  • 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 ...


  • DNA-protein crosslinks induced by formaldehyde and its repair process

    KCL-SDS assay was used to explore DNA-Protein Crosslinks (DPC) effect induced by formaldehyde (FA) and the repair. Gaseous FA could cause DPC at concentrations as 1.0 mg m−3 and 3.0 mg m−3 (p ...

  • 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. ...

  • 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 ...
