Any other information on results incl. tables
Ethanol/methanol was detected in 17 of 25 samples. The average concentration over 24 hours was 0.52 ppb (range 0 - 1.2 ppb). Using a conversion of 1.9 ug/m3 - 1 ppb would imply a concentration of 1.0 ug/m3.
Applicant's summary and conclusion
- Executive summary:
Measurements of ambient ethanol and methanol concentrations in the atmosphere at a remote location in Alaska in the late 1960's found average levels of around 1.0ug/m3. The authors of the study felt that the source of the methanol/ethanol was more likely to be of biological origin rather than man made.
