08 and the average PM total mass concentration per county was 8.1 μg/m -below the United States' National Ambient Air Quality Standard of 12 μg/m . We found a consistent positive association between ALS aggravation and OM (1.17, 95% confidence intervals [CI], 1.11, 1.24 per standard deviation [SD] increase) and a negative association with soil (RR = 0.91, 95% CI, 0.86, 0.97). Our findings suggest that PM composition may influence its effect on ALS. We found that annual increases in county-level particulate OM may be associated with
