To assess risks and costs of hospital admission associated with short term exposure to fine particulate matter with diameter less than 2.5 µm (PM2.5) for 214 mutually exclusive disease groups. ⋯ New causes and previously identified causes of hospital admission associated with short term exposure to PM2.5 were found.
