| Abstract: | "Chemical herder augmented in-situ burning (ISB) is one of the most viable oil spill response techniques in partially ice-covered waters. Herein we report on the impacts of herder-mediated ISB tests on ambient air quality by making atmospheric measurements during ISB field tests in partially ice-covered waters in Fairbanks, Alaska. Concentrations of PM(2.5), six combustion gases (CO, CO(2), NO, NO(2), NOx, SO(2)), volatile organic compounds (VOCs), and herding agent (OP-40) in the airborne plume (6-12 m downwind) were measured during three ISB events. PM(2.5) concentrations significantly (p-value = 0.8014) exceeded NAAQS (24 h) exposure limits, while the remaining pollutants were found significantly (p-value <0.05) below the established exposure limits. OP-40 herder was not detected in the collected aerosol samples. To our knowledge, this is the first study on atmospheric emissions in the vicinity of a field-scale herder-augmented oil-spill ISB study in a high-latitude Arctic environment and provides information that is helpful to ensure the safety and well-being of on-site response personnel" |
