Consider the following statements regarding PM2.5 and its links to non-communicable disease burden:

Statements

1. PM2.5 is associated with triggering inflammation and oxidative stress in the human body, which impairs insulin sensitivity and thereby raises the risk of type 2 diabetes.
2. The Global Burden of Disease project attributes a greater share of diabetes-related healthy years lost worldwide to household solid-fuel smoke than to outdoor ambient PM2.5 exposure.
3. Coarser particulate matter (PM10) has been studied in relation to type 2 diabetes risk, in addition to fine particulate matter (PM2.5).
