Regression equations to estimate mass concentration (y in μg/m3) from DC1700 number concentration (x = small bin particles/cm3). For particle concentrations (x) less than 106 particles/cm3
| Aerosol | Equation | R2 |
|---|---|---|
| 0.9% Salt Aerosol | y = 2.6 × x − 22 | 0.96 |
| 5% Salt Aerosol | y = 6.2 × x − 153 | 0.99 |
| Arizona Road Dust | y = 8.6 × x + 98 | 0.98 |
| Diesel Fume | y = 54 × x + 511 | 0.91 |
| Welding Fume | y = 12 × x − 12 | 0.96 |
