Monitoring methods for fine dust pollution during construction operations

Abstract

The development of the measures in the environment and labor safety in construction production put more attention not only to the risks of harming the employee, but also to such subtle and little noticeable phenomena as dust and vibration. The technological processes on construction sites, in construction production, carry a hidden threat. Also, the dust released during construction works is a threat to residents of nearby construction sites that do not have the means to remove dust. The most dangerous dust pollution is fine dust pollution of dust particles with sizes of 0.5–10 μm (PM0,5-PM10). This article discusses a method for suppressing dust emission on a construction site. The results of the effectiveness of the developed equipment, including fog formation, were obtained in the course of field measurements during many technological processes on the construction site in Rostov-on-Don. These results show that the amount of fine dust PM2.5-PM10 pollution reduces under the influence of water fog gun with a magnetic nozzle equipment using. The concentration of particles in the air reduces almost by 2 times, depending on the height of the equipment’s impact. The reducing of the sanitary protection zone size and the additional costs for removing fine dust in the working area allow the contractor to save money allocated for dust suppression on the construction site and direct them to environmental protection measures during infill construction.
