Dust atlas of construction works in point-pattern housing development

With the development of megacities, active construction is becoming a key factor in the deterioration of atmospheric air quality due to the release of fine particulate matter, such as PM0.5–PM10. These particles pose a significant environmental risk. Given the increasing demand for dense urban development, issues of air purification and environmental stability are coming to the fore. A thorough understanding of the physical and chemical characteristics of dust is fundamental to developing and implementing dust protection measures on construction sites, including the selection of suitable dust collectors. A new approach has been developed for the analysis of dust particles generated by construction work at various urban sites. As part of this approach, a dust atlas has been created that organizes and classifies the diverse types of construction dust, detailing their physical and chemical characteristics. The atlas is based on a unique methodology that enables the identification and description of the main properties of each type of dust encountered during construction operations. Each type of dust studied in this research was assigned its own specification, which includes both the analysis methodology and the identified characteristics of the dust. Documentation related to dust testing contains all the necessary information, including the type of dust, the method of data collection, the time of measurement, the materials used, and the results of dust analysis. For the study, dust samples were taken from the air during construction processes. The study of dust on construction sites revealed that particle size varies significantly, a phenomenon that cannot be attributed solely to measurement errors. These variations in dust particle size can be attributed both to the specific nature of the work performed and to external conditions, including changes in humidity and wind intensity.
