ambient air pollution and respiratory Emergency Department visits
Epidemiology, 2005Co-Authors: Jennifer L Peel, James A Mulholland, Kristi Busico Metzger, Paige E Tolbert, Mitchel Klein, Dana W Flanders, Knox H Todd, Barry P Ryan, Howard FrumkinAbstract:Background:A number of Emergency Department studies have corroborated findings from mortality and hospital admission studies regarding an association of ambient air pollution and respiratory outcomes. More refined assessment has been limited by study size and available air quality data.Methods:Measu

ambient air pollution and cardiovascular Emergency Department visits
Epidemiology, 2004Co-Authors: Kristi Busico Metzger, James A Mulholland, Paige E Tolbert, Mitchel Klein, Jennifer L Peel, Dana W Flanders, Knox H Todd, Barry P Ryan, Howard FrumkinAbstract:Background Despite evidence supporting an association between ambient air pollutants and cardiovascular disease (CVD), the roles of the physicochemical components of particulate matter (PM) and copollutants are not fully understood. This time-series study examined the relation between ambient air pollution and cardiovascular conditions using ambient air quality data and Emergency Department visit data in Atlanta, Georgia, from January 1, 1993, to August 31, 2000. Methods Outcome data on 4,407,535 Emergency Department visits were compiled from 31 hospitals in Atlanta. The air quality data included measurements of criteria pollutants for the entire study period, as well as detailed measurements of mass concentrations for the fine and coarse fractions of PM and several physical and chemical characteristics of PM for the final 25 months of the study. Emergency Department visits for CVD and for cardiovascular subgroups were assessed in relation to daily measures of air pollutants using Poisson generalized linear models controlling for long-term temporal trends and meteorologic conditions with cubic splines. Results Using an a priori 3-day moving average in single-pollutant models, CVD visits were associated with NO2, CO, PM2.5, organic carbon, elemental carbon, and oxygenated hydrocarbons. Secondary analyses suggested that these associations tended to be strongest with same-day pollution levels. Conclusions These findings provide evidence for an association between CVD visits and several correlated pollutants, including gases, PM2.5, and PM2.5 components.

short term associations between ambient air pollutants and pediatric asthma Emergency Department visits
American Journal of Respiratory and Critical Care Medicine, 2010Co-Authors: Matthew J Strickland, James A Mulholland, Mitchel Klein, Dana W Flanders, Lyndsey A Darrow, Jeremy A Sarnat, Lance A Waller, Stefanie Ebelt Sarnat, Paige E TolbertAbstract:Rationale: Certain outdoor air pollutants cause asthma exacerbations in children. To advance understanding of these relationships, further characterization of the dose–response and pollutant lag effects are needed, as are investigations of pollutant species beyond the commonly measured criteria pollutants. Objectives: Investigate short-term associations between ambient air pollutant concentrations and Emergency Department visits for pediatric asthma. Methods: Daily counts of Emergency Department visits for asthma or wheeze among children aged 5 to 17 years were collected from 41 Metropolitan Atlanta hospitals during 1993–2004 (n = 91,386 visits). Ambient concentrations of gaseous pollutants and speciated particulate matter were available from stationary monitors during this time period. Rate ratios for the warm season (May to October) and cold season (November to April) were estimated using Poisson generalized linear models in the framework of a case-crossover analysis. Measurements and Main Results: Both ozone and primary pollutants from traffic sources were associated with Emergency Department visits for asthma or wheeze; evidence for independent effects of ozone and primary pollutants from traffic sources were observed in multipollutant models. These associations tended to be of the highest magnitude for concentrations on the day of the Emergency Department visit and were present at relatively low ambient concentrations. Conclusions: Even at relatively low ambient concentrations, ozone and primary pollutants from traffic sources independently contributed to the burden of Emergency Department visits for pediatric asthma.
