An advance publication article from Environmental Health Perspectives investigates the “joint associations between particulate air pollution, ambient temperature, and respiratory morbidity.” To conduct the study, the researchers reviewed survey results from 2006-2010 and estimated daily averages of particulate matter and air temperature.

After analyzing the results, the researchers concluded that an increase in particulate matter “may be associated with an increase in the prevalence of asthma symptoms,” even at low levels.
