PreciseInhale Provides High-Precision, Groundbreaking Results in New Study of Inhaled Household Pollutants in the Journal of Environmental Science and Pollution Research
Perfluoro-octanic acid (PFOA) is an industrial surfactant used in industries, chemical processes and households around the world. It is commonly found in carpets, upholstery, clothing, floor wax, sealants, textiles and many more. Concerns and research on the toxicity of PFOA are long established, with the substance considered a possible carcinogen, toxic to the liver, and toxic to the immune system (1).
Now, in a new study conducted at
Unlike conventional “tower test” technologies, ISAB’s intubation method delivers aerosol directly into the lungs of individual test rodents, bypassing the nose, while carefully monitoring aerosol concentration and patterns. individual respiratory. The result is exceptionally accurate data.
In this study, the accuracy of the PreciseInhale results was indeed high – with a standard deviation of 10-15% in all exposed subjects. In new unpublished results, PreciseInhale also found that the blood concentration of PFOA in rats was four times higher when inhaled than when ingested after exposure to the same levels of dust. This is a very socially relevant result demonstrating that inhalation is an effective exposure channel for pollutants like PFOA both at home and at work.
Manoush Masarrat, CEO of ISAB: “These precise, revealing and important results show how much inhalation science can offer research on environmental medicine and air pollution. The unique accuracy and precision offered by PreciseInhale in this case really allowed scientists to reach a higher level of understanding aerosol data.”
