Researchers discuss the development of a low-cost air pollution measurement system.
By Dr. Chinta SidharthanOct 30 2023Reviewed by Benedette Cuffari, M.Sc. In a recent study published in Scientific Reports, researchers discuss the development of a low-cost air pollution measurement system and validate the system by measuring particulate matter levels across four years in rural areas frequented by children.
Most major cities in the European Union have at least one government-supported station for monitoring air quality. However, accurate systems for measuring particulate matter levels are expensive, which makes the establishment of such systems unfeasible in smaller towns and rural areas. Other parameters such as air temperature, pressure, and humidity were also measured along with particulate matter levels using the university measuring stations that are part of the Storm&DustNet measurement network. The university measuring stations monitor the concentrations of suspended and airborne particulate matter of diameters ranging from 10-0.3 µm. Measurements were obtained every two seconds to calculate the average measurements for each minute.

The study period included heating periods between the months of April and September and cold periods between October and March. The lowest PM10 values, on average, were obtained from stations installed near a primary school in a village or a small village close to a green space and without too many buildings. The average PM10 concentration values during the heating periods did not exceed 19 µg per m3 for any of the stations.
