Linear Regression Modeling of Selected Analytes from the Balad Air Sampling Program
Abstract
Joint Base Balad (JBB) / Logistics Support Area Anaconda (LSAAnaconda) utilized burn pits from 2003-2009 to facilitate and manage solid waste disposal. The base transitioned in phases from burn pit to incinerator use from June 2007 to October 2009. The Air Force Institute for Operational Health andthe U.S. Army Center for Health Promotion and Preventive Medicine began anambient air sampling program to determine pollutant emissions generated fromthe JBB burn pit. Ambient air sampling periods were: January April and October November 2007, May June 2009, and March May 2010. Data from the Balad Air Sampling Program are analyzed to explore possible temporal trends in ambient air quality for selected analytes from the VOC, PAH, Dioxin and Furan chemical groups during the transition from burn pit to incinerator operation.The results from linear fixed effect regression model indicate that benzo[a]pyrene observed a positive correlation between analyte log concentration and the sampling periods, suggesting that the overall ambient air quality at JBB decreased with Benzo[a]pyrenes increased log concentration value over time. Whereas, the analyte log concentrations for tetraCDD, benzene, n-heptane, cadmium and lead observed a negative correlation (decrease in log concentration over the sample periods) suggesting that the overall ambient air quality at JBB increased with the analytes between log concentration values during the transition from burn pit to incinerator operation.
