Hospitalizations linked to PM2.5

Hospitalizations for several common diseases have been linked for the first time with short-term exposure to fine particulate air pollution (PM2.5), according to a comprehensive new study led by Harvard T.H. Chan School of Public Health.

Fine particulate air pollution is composed of tiny solids and liquids floating in the air that come from sources such as motor vehicles, coal-fired power plants, and wildfires. Previous studies have shown that, when inhaled, the particles can enter deep into the lungs and cause serious health problems.

In addition to showing that short-term exposure to PM2.5 was associated with several newly identified causes of hospital admissions among older adults, the study confirmed previously identified associations between short-term exposure and hospitalization risk for a number of other ailments, including several cardiovascular and respiratory diseases, Parkinson’s disease, and diabetes.

In an economic analysis, researchers found that each 1 μg/m3 increase in short-term exposure to PM2.5 was associated with an annual increase of 5,692 hospitalizations, 32,314 days in the hospital, and 634 deaths, corresponding to $100 million annual inpatient and post-acute care costs, and $6.5 billion-used to determine the economic value of lives lost.
