Measurements of hydrocarbons and reduced sulfur compounds emitted from a wastewater treatment pond
- BOVAR Environmental, Toronto, Ontario (Canada)
A flux chamber was deployed on the water surface to monitor the emissions of hydrocarbons and reduced sulfur compounds from a wastewater treatment pond at a refinery site. Air samples were collected in Tedlar bags and analyzed on-site by means of a gas chromatograph/flame ionization detector (GC/FID) for hydrocarbons and a gas chromatograph/flame photometric detector (GC/FPD) for reduced sulfur compounds. The standard deviations of the duplicate samples for hydrocarbons and for reduced sulfur compounds were better than 4% and 11%, respectively. The pond was monitored during the daytime and nighttime, under two different weather conditions where the daytime temperatures were about 22{degrees}C and 14{degrees}C. The results showed that the difference between day and night emissions of hydrocarbons and reduced sulfur compounds were greater during the warm weather compared to those during cool weather. Air samples were also collected with charcoal adsorbent tubes and analyzed by means of a gas chromatograph/mass selective detector (GC/MSD) at the BOVAR Environmental (BE) laboratory to confirm the GC/FID hydrocarbon analyses. There was excellent agreement between hydrocarbons identified by GC/FID and GC/MSD. 10 refs., 3 figs.
