Emissions of formaldehyde and volatile organic compounds (VOCs) from building materials may result in poor indoor air quality. The emission process can be divided into three stages over time: early, transition, and equilibrium stages. In existing studies, mass transfer models without distinguishing the early and transition stages have been widely used for characterizing the formaldehyde/VOC

The objective of this study is to characterize indoor and outdoor levels of volatile organic compounds (VOCs) and formaldehyde (HCHO) and 

Sources of VOC and formaldehyde emissions are numerous and range from sources of combustion (tobacco, candles, incense, fireplaces, etc.) 

The comparison diagram of the response values of different gas at 500 ppm (Figure 3f) shows the response of the three sensors to a variety of VOCs. It can be seen that the WO 3-CA has high sensitivity to 1,2,3-trimethylbenzene, tridecane, undecane, decane, nonane, acetone, formaldehyde and n-heptaldehyde. In addition, the responses for benzene

What's more, the effectiveness of VOC removal varied considerably among such as formaldehyde, that added to the overall pollutant level.

Volatile Organic Compounds (VOCs) are chemicals that evaporate easily at room temperature. The term organic indicates that the compounds contain carbon. Common examples of VOCs that may be present in our daily lives are: benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene

One of the most common VOCs is formaldehyde, an organic compound that occurs naturally in everything around us, including our own bodies. However, when fabricated into the chemical compound used in synthetic materials such as glues, sealants, paint, coatings, and plastics, it can become one of the most toxic VOCs in the home.

Among the various indoor air pollutants, formaldehyde (HCHO) and some other volatile organic compounds (VOCs) such as toluene and xylenes are of
