LESSON THREE

As can be seen in Table 4, over the five-year timeframe, the fraction of PM10 that consists of PM2.5 is consistently 21 percent. Multiplying the fugitive PM2.5 percent fraction of PM10 by the existing construction PM10 LST, 10.4 μg/m3, produces a result of approximately 2.2 μg/m3. ................
