Many concerns about air quality are voiced by many. More attention is usually paid to some problems with air quality, namely carbon dioxide concentration, volatile organic compounds (VOC) and bacteria emissions. However, aerosols or respirable particulate matter are sometimes overlooked.
It is clear that there is a relationship between the particulate matter mass concentration (PM10) and the relative humidity of the ambient air. The lower the relative humidity of the ambient air, the higher the PM10 concentration.
Particulate matter is a general term used for the mixture of solid particles and liquid droplets present in the air. Airborne particulate matter comes from many different sources. Primary particles are released directly into the atmosphere from sources such as cars, trucks, heavy equipment, wildfires, and other combustion activities. Material from sources such as unpaved roads, stone crushing, construction sites, and metallurgical processes are also primary particles. Secondary particles in the air consist of reactions involving chemical compounds such as sulfates from sulfur dioxide emissions from power plants and industrial facilities, nitrates from nitrogen dioxide emissions from cars, trucks, and power plants, and carbon-containing reactive organic gas emissions from biogenic sources such as cars, trucks, industrial facilities, wildfires, and trees.
Air concentrations of particulate matter are measured by ambient air monitoring stations across the country. In general, monitoring is done for PM2.5 and PM10 sizes. PM2.5 consists of fine particles with aerodynamic diameters of 2,5 microns or less. PM10, on the other hand, consists of fine and coarse particles with aerodynamic diameters greater than 2,5 microns and less than 10 microns. The chemical structure of these particles is different from each other. Some contain more sulfates, while others contain more nitrates. Carbon is an important component of fine particles everywhere. Unlike other pollutants, particulate matter is not a single specific chemical entity, but rather a mixture of particles from different sources with different chemical compositions.
Our organization, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, also provides services for the determination of the mass concentration of particulate matter with its trained and expert staff and advanced technological equipment.
