Cancelada, Lucia published the artcileHeated Tobacco Products: Volatile Emissions and Their Predicted Impact on Indoor Air Quality, Quality Control of 123-39-7, the main research area is heated tobacco product volatile emission indoor air pollution; IQOS apparatus heated tobacco product.
This work characterized emissions from IQOS, a heated tobacco product promoted as a less harmful alternative to cigarettes. Consumable tobacco plugs were analyzed by headspace gas chromatog./mass spectrometry to assess the heating temperature effect on the emission profile. Yields of major chem. constituents increased from 4.1 mg/unit at 180° to 6.2 mg at 200°, and 10.5 mg at 220°. The Health Canada Intense smoking regime was used to operate IQOS in an environmental chamber, quantifying 33 volatile organic compounds in mainstream and side-stream emissions. Aldehydes, nitrogenated species, and aromatic species were observed as were other harmful and potentially harmful compounds Compared to combustion cigarettes, IQOS yields were, in most cases, 1-2 orders of magnitude lower; however, yields were closer to and sometimes higher than, electronic cigarettes. Predicted user daily average benzene, formaldehyde, acetaldehyde and acrolein intakes were 39, 32, 2.2, and 71 μg, resp. Indoor air concentrations were estimated for commonly encountered scenarios, with acrolein levels of concern (>0.35 μg/m3) derived from IQOS used in homes and public spaces. Heated tobacco products are a weaker indoor pollution source than conventional cigarettes, but their impacts are not negligible nor fully understood.
Environmental Science & Technology published new progress about Apparatus (IQOS tobacco product heating). 123-39-7 belongs to class amides-buliding-blocks, name is N-Methylformamide, and the molecular formula is C2H5NO, Quality Control of 123-39-7.
