Title: Source analysis of particulate-phase polycyclic aromatic hydrocarbons in an urban atmosphere of a Northern City in China

Abstract

Particle-associated polycyclic aromatic hydrocarbon (PAH) concentrations were investigated at six sampling sites in the heating (February to March 2001) and nonheating (August to September 2001) periods in an industrial city in Northern China. Thirteen PAHs were measured. The total average concentrations (nanograms per meter cubed) of PAHs ranged between 78.93 and 214.63 during the heating period and from 31.48 to 102.26 in the nonheating period. Benzo(a)pyrene occurred at the highest level at a site near an industrial area but occurred at low concentrations far from the city center and industrial areas. In addition, ambient PAH profiles were studied. The five and six-ring species occurred in high fractions at the sampling site. By diagnostic ratio analysis, the major source at each sampling site in the city was coal combustion in the heating period; in the nonheating period, the major sources were relatively complex. Finally, the similarities among the six regions were assessed by principal component analysis, cluster analysis, and coefficient of divergence. These multivariate statistical analyses produced similar results, which agreed with the results from the diagnostic ratio analysis. 47 refs. 5 figs., 3 tabs.

  • Levels of polycyclic aromatic hydrocarbons (PAH) have been measured in the air particulate matter (APM) of a lightly industrialized urban area in which the main sources of PAH are domestic fires and automobiles. The PAH were analyzed by glass capillary gas chromatography combined with mass spectrometry. Statistical analysis of the results using 26 PAH allows the relative contribution of the two sources to be estimated and shows that during periods of heavy pollution (APM > 100 ..mu..g m/sup -3/) domestic fires are the main contributors. A simpler ratio, ln (1 + (benzofluoranthenes)/(total PAH)) - ln (1 + (benzo(ghi)perylene)/(total PAH)), givesmore » similar discrimination.« less
  • Taichung is the largest city in the central part of Taiwan, and its air pollution problems are similar to those in other large cities around the world. To evaluate the potential of the air pollution and identify major pollutant sources in this city, 181 airborne particulate samples were collected biweekly from seven locations around Taichung over an entire year. The mutagenicity of acetone extracts of the air samples was evaluated using the Salmonella/microsomal test with Salmonella typhimurium TA98 in the presence and absence of S9 mixtures. The air samples from September 1994 showed the highest direct and indirect mutagenicity, respectively.more » To elucidate the correlation between mutagenicity and polycyclic aromatic hydrocarbons (PAHs), high-performance liquid chromatography was used to determine the amount of each of 10 PAHs in the air samples.« less
  • In recent years, Mexico City's atmosphere has suffered significant changes in several of its climatological features due to the fast growth of the city and to the gradual deterioration of its air quality. The most noticeable alterations are: an increase in air temperature, increase in rain precipitation and reduction of solar radiation, produced mainly by the presence of atmospheric aerosols, particles, dusts and toxic gases originated from industrial activity besides the emanation caused by fossil hydrocarbons combustion and the supply of natural sources. Among the organic compounds present in atmospheric particles, the saturated and aromatic hydrocarbons have outstanding importance duemore » to their carcinogenic potential and its formation from different photochemical reactions. Thus, the observed changes in the physical factors that take place in the climatic system have reached magnitudes that work as harmful agents for the inhabitants of Mexico City producing discomfort and chronic diseases of the respiratory system.« less
  • In Quebec, Canada the production of primary aluminum using the Horizontal Stud Soderberg process is a significant source of atmospheric emissions. Since 1984, in the area surrounding a Soderberg plant at Jonquiere, Quebec, regular monitoring of the ambient air has made it possible to follow the evolution of PAH levels in urban areas. B[a]P is used as an indicator of total PAH. The ambient air is sampled twice a week using Hi-Vol samplers to collect particulate PAH on glass-fiber filters. From 1984 to 1990, there has been a 67 percent reduction in PAH emissions at the Jonquiere plant. The twomore » factors contributing to this situation are the shutdown of certain Soderberg production units and an ongoing program of reduction of PAH emissions into the atmosphere. Annual geometric mean ambient levels of 1 to 3 ng/m[sup 3] (B[a]P) for 1990 have been reported at sampling stations affected by prevailing winds within a 6 km radius of the emissions source. This paper shows the representativeness of the PAH sampling network in the area surrounding the industrial site. There is a general trend towards lower levels of B[a]P in air coincident with the emissions reduction program. A verification of the data shows that they are not normally distributed but are highly right-skewed and generally follow lognormal distributions. 9 refs., 5 figs., 5 tabs.« less
  • Molecular distributions of polycyclic aromatic hydrocarbons (PAHs) in street dust samples collected from the Tokyo metropolitan area were determined by capillary gas chromatography following HPLC fractionation. Sixty-four compounds including three- to six-ring PAHs and sulfur heterocyclics were identified by capillary GC/MS. Total PAH concentrations were in the range of a few micrograms per gram of dust. The source materials (automobile exhaust, asphalt, fuel-oil combustion products) were also analyzed. The PAH profile, especially relative abundance of alkyl-PAHs and sulfur-containing heterocyclics, indicated that PAHs in the street dusts on the heavily trafficked streets are strongly affected by automobile exhaust and those inmore » the residential area have a somewhat more significant contribution from combustion products in stationary sources. With both types of dusts, asphalt is through to contribute only a minor part of their PAHs.« less
