Acrolein is used primarily as an intermediate in the manufacture of acrylic acid and is also used directly as an aquatic herbicide and algaecide in irrigation canals. It is found in gaseous form in the products of combustion of tobacco, cooking oils, fossil fuels and gasoline. It is produced during fires and is a toxicant to firefighters. Urban acrolein levels as high as 20 Ãg/m3 (-9 ppb) have been reported. Acrolein levels in inside air, especially if tobacco smoking is permitted, can be even higher.
Human odor threshold for acrolein is 370 Ãg/m3. NIOSH recommended exposure limit (810 hour timeweighted average exposure) for acrolein is 250 Ãg/m3 (i.e., 108 ppb). Pranalyticaâs Chemiluxâ¢Acrolein sensor can provide more than adequate level of margin for assuring human safety in work as well as urban environments.
