Associations between Ambient Fine Particulate Oxidative Potential and Cardiorespiratory Emergency Department Visits.

ABSTRACT:

Background

Oxidative potential (OP) has been proposed as a measure of toxicity of ambient particulate matter (PM).

Objectives

Our goal was to address an important research gap by using daily OP measurements to conduct population-level analysis of the health effects of measured ambient OP.

Methods

A semi-automated dithiothreitol (DTT) analytical system was used to measure daily average OP (OP^DTT) in water-soluble fine PM at a central monitor site in Atlanta, Georgia, over eight sampling periods (a total of 196 d) during June 2012-April 2013. Data on emergency department (ED) visits for selected cardiorespiratory outcomes were obtained for the five-county Atlanta metropolitan area. Poisson log-linear regression models controlling for temporal confounders were
