|Abstract:|| Exposure assessments of open burn pits are often complicated by a lack of sampling equipment and resources. This research investigated the hypothesis of carbon dioxide (CO2) as a viable surrogate for particulate matter with diameter ? 2.5 µm (PM2.5). Large-scale solid waste combustion tests were conducted, resulting in linear trends between mean PM2.5 and mean CO2 (R2=0.964 - 0.989). This pilot study indicates the potentially beneficial reduction in particulate matter when using batch-feeding practices with burn boxes (versus open burning). It also demonstrates the feasibility of using CO2 as a surrogate of PM2.5 concentration, providing a cost-effective solution in lieu of expensive PM instruments.
