| Abstract: | Black carbon(BC) aerosols concentrations observed in Benxi from March 2008 to February 2009 were analyzed.Results showed that the mean concentration of atmospheric BC aerosols in Benxi was 6.877 μg/m3 and daily mean concentration varied from 0.592 μg/m3 to 20.577 μg/m3,with hourly concentration maximum of 64.518 μg/m3.Because of the influences of winter heating and high frequency of temperature inversion in the surface layer,the concentration of BC varied with season obviously,the concentration value was low in summer,and the highest BC concentration appeared in January.Daily variation of BC concentration was characterized by a pronounced double peak patterns,with the higher concentration during 6:00~9:00 AM and 17:00~19:00 PM,and the lower one during 2:00~4:00 AM and 12:00~5:00 PM.Compared to the domestic cities such as Beijing,Wenjiang in Sichuan,and Xi’an,Benxi has roughly the same concentration,but the BC concentration in Benxi is obviously higher than foreign cities. |
