Impact/Purpose:
Summarizing a 1-year monitoring study in Sarajevo, BiH investigating data collected between May 2018 and August 2019, including temporal trends, comparison of the two regulatory-grade monitors, and exploratory analysis of the very high time-resolution PM2.5 measurements. The monitoring study took place at the United States Embassy and was a unique location worldwide by operating two different types of regulatory-grade instruments that measure PM2.5 continuously.
Description:
Exposure to air pollutants is linked to a wide range of health effects. Within a complex mixture of air pollutants, fine particulate matter (PM2.5 or particles generally smaller than 2.5 micrometers) is a challenging pollutant worldwide due to the myriad of sources that contribute to particles in the atmosphere; its atmospheric residence time that can last from days to weeks; its complex chemical composition and physical morphology; and its ability to travel hundreds or thousands of kilometers potentially influencing air quality in regions far from the original sources. Fine particles are of great interest to environmental health professionals because of the strength of the scientific data linking PM2.5 exposures with premature mortality and morbidity. The World Health Organization has established air quality guidelines and many countries worldwide regular PM2.5 and other key air pollutants that pose health risks. This presentation will summarize the results from a year-long field study to measure PM2.5 in Sarajevo, Bosnia and Herzegovina. The monitoring study took place at the United States Embassy and was a unique location worldwide by operating two different types of regulatory-grade instruments that measure PM2.5 continuously. One monitor’s optical detection method supported measurements of PM2.5 as fast as a one-minute resolution; meanwhile, the method relying on beta-attenuation for detection reported data at an hourly resolution. Investigation of the data collected over the timeframe of May 2018 through August 2019 will be presented, including temporal trends, comparison of the two regulatory-grade monitors, and exploratory analysis of the very high time-resolution PM2.5 measurements.
