Mono-ethanol amine (MEA) used in the degreaser and being present in a room on cleaned surfaces and paper towel used for their cleaning transformed ammonium sulfate and ammonium nitrate into (MEA)2SO4 and (MEA)NO3. This effect was visible for several days despite a high average ventilation rate. Replacement of ammonia in ammonium salts was seen both in aerosol and in particles collected on a filter before the usage of MEA degreaser. The described influence shows a new pathway for MEA exposure of people in an indoor environment that can be important especially for professionals working with similar
degreasers. The stabilizing effect on indoor nitrate also causes higher indoor exposure to fine nitrates.
