NMF reveals characteristic compositions of VOCs in indoor environments and emphasizes that constantly recurring structures are not single sources, but rather fusions of them, so called patterns. Interpreting these sources, we realized that homes were strongly influenced by ventilation, human activities, ...
Regardless of how good they smell, artificial fragrances abound with dangerous chemicals and volatile organic compounds (VOCs). One of them, you guessed it, is formaldehyde. This and other chemicals pose a danger to your immune and respiratory systems. 7. Air fresheners Much like plug-in fragra...
Indoor air pollution is the presence of one or more contaminants indoors that carry a certain degree of human health risk. Indoor air issues may be traced to the beginning of civilization. Prehistoric records note the problem of smoke in caves. However, over the last three decades the public ...
Household pollutants are contaminants that are released during the use of various products in daily life. Studies indicate that indoor air quality is far worse than that outdoors because homes, for energy efficiency, are made somewhat airtight. Moreover, household pollutants are trapped in houses ...
In large part, the significant sources of chiral pharmaceuticals stem from industrial processes, such as the direct discharge of untreated or incompletely treated wastewaters containing chiral pharmaceuticals, incorrect storage and use, animal wastes and biosolids. The main ways for human exposure to ...
I would not assume that "dead mold" is really "dead" - dormant mold, meaning mold growth on a surface that is not producing active growth, can become active seasonally with variations in humidity, temperature, light, and other conditions, and can outgas MVOCs at times - depending on the ...
lamps for air purification have the advantage of producing UVC radiation that does not require direct line-of-sight exposure for germicidal effectiveness. Ozone can reach places that other UVC lamps cannot and are effective at eliminating foul odor in the air and volatile organic compounds (VOCs)....
and many other contaminants and volatile organic compounds (VOCs). UVC lamps generate UV radiation at 254 nanometer (nm) which is required to penetrate the nucleic acid of the harmful cells, altering the DNA to render it harmless and unable to reproduce. UV radiation emitted at 185nm generates...
UVC radiation is proven to quickly and effectively destroy airborne contaminants including bacteria, fungi, mold, viruses, and volatile organic compounds (VOCs). By penetrating the nuclei of the harmful cells, UVC radiation immediately renders them harmless and unable to replicate.UV air purifiersoperat...
Another important area of ultraviolet air purification is in industries that produce toxic chemicals such as printing, plastics and rubber, or wood and surface treatment.Germicidal UV technologyis used to reduce or eliminate volatile organic compounds (VOCs), which are organic chemicals that have a ...
