Abstract
Few air quality measurements have been reported for the country of Haiti, limiting our understanding of the contribution of air quality to disparities in health endpoints. Solid fuel use for cooking by over 90% of Haitian households suggests significant chronic exposure to carbon monoxide and particulate matter (PM) [1]. Transportation emissions also contribute to poor air quality in urban and peri-urban areas. Recent advances in the design and calibration of lower-cost sensing platforms such as ARIsense provide the means to better understand ambient air quality and evaluate exposure in resource-challenged areas [2].

We will present ambient monitoring and personal exposure measurements from a broader study of chronic carbon monoxide exposure and health in Cap Haïtien, Haiti. Monitoring consists of lower-cost ARIsense integrated sensor packages (CO, CO2, NO, NO2+O3, PM, relative humidity, temperature) deployed to two primary schools in urban and peri-urban neighborhoods. Stationary monitoring at the schools also includes quartz filter sample collection for offline organic speciation with a Filter Thermal Desorption Aerosol Gas Chromatograph (Filter TAG). Personal exposure to carbon monoxide among students at the schools is assessed with integrated passive dositube measurements as well as continuous measurements from low-cost electrochemical sensors. We evaluate ambient and personal measurements to investigate drivers of personal exposure.
