| Chemical components
responsible for haze |
|
| In Lake Sugema, the average
PM2.5 mass concentration during 6/2002-8/2003 is 10.7 µg/m3, and the average
total light extinction coefficient (Bext) is 94 Mm-1 (Visual Range ~ 42
Km; Deciview ~ 22). Sulfate and nitrate are two of the largest contributors
to haze, with an average contribution of 42% and 27%, respectively. Figure 3
indicates that sulfate in the summer and nitrate in the winter are the major
causes of haze at LASU1. |
