Modeling of regional climate change effects on ground-level ozone and childhood asthma.

ABSTRACT:

Background

The adverse respiratory effects of ground-level ozone are well established. Ozone is the air pollutant most consistently projected to increase under future climate change.

Purpose

To project future pediatric asthma emergency department visits associated with ground-level ozone changes, comparing 1990s to 2020s.

Methods

This study assessed future numbers of asthma emergency department visits for children aged 0-17 years using (1) baseline New York City metropolitan area emergency department rates; (2) a dose-response relationship between ozone levels and pediatric asthma emergency department visits; and (3) projected daily 8-hour maximum ozone concentrations for the 2020s as simulated by a global-to-regional climate change and atmospheric chemistry model.
