Distribution of cumulative PCE exposure before LMP, peak annual PCE exposure before LMP, and average monthly PCE exposure during LMP year among exposed subjects.
| Cumulative | Cumulative exposure (g) before LMP month and year (n = 1,201)a | Peak annual exposure (g) before LMP year (n = 955)a | Average monthly exposure (g) during LMP year (n = 1,106)a |
|---|---|---|---|
| Minimum | 2.8 × 10−4 | 1.212 × 10−3 | 1.176 × 10−4 |
| 10th percentile | 1.1 | 1.3 | 3.98 × 10−2 |
| 5th percentile | 5.6 | 5.6 | 0.2 |
| Median | 29.9 | 19.8 | 0.9 |
| 75th percentile | 120.0 | 63.3 | 3.0 |
| 90th percentile | 334.2 | 161.2 | 7.9 |
| Maximum | 3,904.2 | 1,770.7 | 147.6 |

There were 860 individuals who were exposed both before and during the LMP year. Another 95 individuals were exposed before the LMP year but were unexposed during the LMP year, and another 246 individuals were exposed during the LMP year but were unexposed before the LMP year. Thus, cumulative exposure before the LMP month and year includes 1,201 exposed individuals (860 + 95 + 246), peak annual exposure before the LMP year includes 955 exposed individuals (860 + 95), and average monthly exposure during the LMP year includes 1,106 exposed individuals (860 + 246).
