| Abstract: | "An observation was conducted at the wastewater treatment plant in a refinery in Guangdong province, using the PFPH-GC/MS method to analyze the composition and the concentration of volatile carbonyl compounds. The emission characteristics and the atmospheric chemical reactivity of these compounds were also studied. The results showed that 20 kinds of carbonyl compounds were detected with a concentration range of 0 to 68.80 microg x m(-3). The mean value of total concentration in all processing unit was (253.02 +/- 124.5) microg x m(-3). Background corrected concentrations showed that for each of the 6 treatment units of the plant, over 90% of the volatile carbonyl emissions were contributed by 14 of the 20 volatile carbonyl compounds, among which aldehyde was the most abundant with an average concentration of (44.74 +/- 20.89) microg x m(-3), followed by 2-butanone and acetaldehyde with average concentrations of (30.47 +/- 12.94) microg x m(-3) and (23.51 +/- 14.57) microg x m(-3), respectively. Several molecular markers were identified based on the analysis of the chemical activities and atmospheric lifetimes of the 20 carbonyl compounds. Finally, a source profile was established for the plant" |
