  • 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 ...

  • Case study: Formaldehyde production

    Overiew A major chemical manufacturer required a pollution control system with minimal operational cost to destroy the Hazardous Air Pollutant (HAP) by-products of a formaldehyde production process. A key issue was system reliability; the plant operates 24 hours a day and only shuts down once per year for plant-wide preventive maintenance. ...

  • 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 ...

  • Formaldehyde in rainwater at Trombay, Mumbai: a coastal site in India

    Formaldehyde was measured in rainwater samples collected at a residential area of Trombay, Mumbai (a coastal site in India). A mean concentration of 2.1 µmo1/1 and a range of 0.4-11.0 µmol/l were observed. The mean formaldehyde concentration in rainwater has increased from 1.2 µmol/l in 1979 by a factor of about two at this site.Keywords: coastal site, formaldehyde, India, ...

  • 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 ...

  • 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 ...
