Measurements of air pollutants in San Salvador (El Salvador) downtown
Abstract
Air pollution in large cities is one of the most important environmental problems to solve around the world. In this work, we present measurements of O4, trace gases, and particulate matter in San Salvador (El Salvador) downtown obtained by using differential optical absorption spectroscopy and a single point monitoring instrument. Preliminary results show diurnal mean values of the order of 1017 molecules/cm2 and 1016 molecules/cm2 for NO2 and HONO, respectively. For particulate matter we observed diurnal mean values around 20 μg/m3. The diurnal variation of the amount of these pollutants will be discussed.
