This method can be used for the determination of acetaldehyde and valeraldehyde for OSHA STEL and PEL exposures. Upper limits of the method for the Supelco sampler are 105, 183, 50, and 50 µg per sample for acetaldehyde,
24 Ιουν 2020 · This study was designed to investigate the levels of acetaldehyde residues in polyethylene terephthalate bottled water and its significance in terms of consumer health. We analyzed 104 samples...
Permissible exposure limits (PELs) are how OSHA defines the maximum concentration of chemicals to which a worker may be exposed. PELs are defined in two ways: STEL (15-minute time-weighted average not to be exceeded) or an eight-hour TWA, which is an average value of exposure over an eight-hour work shift.
Acetaldehyde is a dangerous fire hazard (NFPA rating = 4) owing to its volatility and low autoignition temperature. Its vapor is explosive in the concentration range 4 to 66% in air and may be ignited by hot surfaces such as hot plates or lightbulbs, or by static electricity discharges.
In this research, the high precision purity determination method for development of a certified reference material (CRM) of acetaldehyde was examined. By controlling the volatility and reactivity of acetaldehyde, we established the purity determination method of acetaldehyde with a relative standard uncertainty of less than 0.3%.
Acetic aldehyde, Ethanal, Ethyl aldehyde. Colorless liquid or gas (above 69°F) with a pungent, fruity odor. Class IA Flammable Liquid: Fl.P. below 73°F and BP below 100°F.
