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

Popis výsledku v původním jazyce

To the best of our knowledge, this study represents the first observation of multi-day persistence of an indoor aerosol transformation linked to a kitchen degreaser containing mono-ethanol 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)(2)SO4 and (MEA)NO3. This influence persisted for at least 60 hours 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.
