Single Usage of a Kitchen Degreaser Can Alter Indoor Aerosol Composition for Days

Abstract

To the best of our knowledge, this study represents the first observation of multiday persistence of an indoor aerosol transformation linked to a kitchen degreaser containing monoethanol amine (MEA). MEA remaining on the cleaned surfaces and on a wiping paper towel in a trash can was able to transform ammonium sulfate and ammonium nitrate into (MEA)SO and (MEA)NO. This influence persisted for at least 60 h despite a high average ventilation rate. The influence was observed using both offline (filters, impactors, and ion chromatography analysis) and online (compact time-of-flight aerosol mass spectrometer) techniques. Substitution of ammonia in ammonium salts was observed not only in aerosol but also in particles deposited on a filter before the release of MEA. The similar influence of other amines is expected based on literature data. This influence represents a new pathway for MEA exposure of people in an indoor environment. The stabilizing effect on indoor nitrate also causes higher indoor exposure to fine nitrates.

Association of use of cleaning products with respiratory health in a Canadian birth cohort

“…For example, a single use of a kitchen degreaser can affect indoor aerosolized concentrations of irritant chemicals for several days. 40 Data for use of cleaning products from maternal prenatal questionnaires correlated well with the more robust measures from early childhood used in our study, suggesting that these measures are reflective of prenatal exposure. This is consistent with results from the ALSPAC cohort.…”

“…Mixing cleaning products is a common cause of inhalation accidents that increases the risk of asthma and reactive airway dysfunction syndrome. 15,26 With more than 100 different volatile organic compounds identified in a study of cleaning products, 39 the extent of secondary exposures created when common cleaning products are mixed 40 is not fully understood and remains a challenge for researchers to measure accurately. The use of data from the questionnaires has the potential for recall bias as well as social desirability bias.…”

Developing Land-Use Regression Models to Estimate PM2.5-Bound Compound Concentrations

“…Population variables were included in the EC, NH + 4 , and Cu models. This predictor variable represented various human and commercial activities, such as heating, cooking, and cleaning activities [51,59]. For instance, the aminium salts contained in the commercial degreaser solution are released into the air when people use a degreaser to clean kitchens [59].…”

Cooking and electronic cigarettes leading to large differences between indoor and outdoor particle composition and concentration measured by aerosol mass spectrometry

“…[8][9][10][11][12][13][14] Recent studies show that some indoor sources emit ultrane (<100 nm) and ne particles (<2.5 um) of a complex chemical nature. These sources include cooking, [15][16][17][18][19][20] burning candles, [21][22][23] burning incense, 24,25 using cleaning products, [26][27][28][29][30] and electronic cigarette vaping. 31,32 The particle number and mass concentration indoors due to such activities can be orders of magnitude higher than outdoors.…”
