The long-term objective of this project was the design and implementation of a particular epidemiological approach to investigation of ambient pollutant effects: the correlation of pollutant exposure with patterns of hospital emergency room utilization. The report covers the initial phase of development and pilot studies. Separate discussions are provided on the two major components of the methodology: investigation of health effects and estimation of ambient ozone concentrations. The approach to study adverse health effects was premised on the assumption that an increase in community morbidity due to environmental air pollution wouldbe reflected in emergency room patient populations. It was concluded, however, that this was not a useful method for investigation of exposure-response associations. The mapping of ambient ozone concentrations in time and space over the Riverside metropolitan area was investigated using data from two monitoring stations located within the subject area. A procedure was developed for a month-by-month comparative study of the data. (Portions of this document are not fully legible)
