Just two more nuances:
1) The article is measuring loss in "DALYs" = disability-adjusted life years. 10 DALYs lost may not mean dying 10 years earlier, but could also mean suffering from Alzheimer's for 16 years (Alzheimer's has a weight of 0.66 [1]), or any combination thereof (e.g. 10 years of Alzheimer's + dying 3.3 years earlier).
2) The cited number is for the "worst offender" on the NYC metro. The pollution levels on the London underground are less than a 10th of that.
