Abstract
Studies on particulate matter (PM) from construction activities are still at an early stage. Thus, there is still no consensus on standardized experimental methods for monitoring PM in construction sites, which impedes the advancement of knowledge on this subject. This work proposes guidelines for measuring and monitoring the concentration of suspended PM and the annoyance generated by sedimented particles on construction sites in urban areas. These guidelines aim to reduce the variability and uncertainties that exist during the PM sampling processes at construction sites. This study adopts a literature review strategy in order to update the available scientific literature based on empirical evidence obtained in experimental PM studies and relevant documents from government agencies. The proposed guidelines were applied in a study protocol for gravimetric monitoring PM and annoyance tracking generated by sedimented particles using sticky pads. As a result, this article details sampling techniques, procedures, and instruments, focusing on gravimetric sampling, highlighting their characteristics compared to other monitoring approaches. Additionally, it points out a series of parameters for the measurement and monitoring of PM. This paper seeks to support future researchers in this area, inform decision making for experimental sampling, and provide a benchmark for measuring and monitoring PM at construction sites.
Highlights
Most of the world’s population experiences long-term exposure to environments with various air pollutants, such as ozone, nitrogen dioxide, carbon monoxide, and particulate matter (PM) [1]
The authors adopt the national standards of Brazil (Resolution No 491/2018) and the reference values established by the World Health Organization (WHO), which are more restrictive, for comparison purposes with the concentration levels obtained in the monitored construction sites
This is a sampler that monitors the total suspended particles (TSP), PM10, and PM2.5 fractions using a suction pump; They usually provide average concentrations over 24 h and require laboratory determination to identify the mass of the filters; The concentrations obtained can be associated with air quality limit values; Reference methods for monitoring suspended particles are based on gravimetric samplers
Summary
Most of the world’s population experiences long-term exposure to environments with various air pollutants, such as ozone, nitrogen dioxide, carbon monoxide, and particulate matter (PM) [1]. The authors argued that a location-based real-time PM monitoring system could provide accurate measurements, as it considers the distributional characteristics of the different PM sizes [22,23]. In this context, this article proposes guidelines for measuring and monitoring the concentration of suspended PM and the annoyance generated by sedimented particles on construction sites in urban areas. This article proposes guidelines for measuring and monitoring the concentration of suspended PM and the annoyance generated by sedimented particles on construction sites in urban areas These guidelines aim to contribute to the identification of research variables in order to reduce the variability and uncertainties that exist during the PM sampling processes in construction sites. The guidelines were applied in a PM study protocol for gravimetric monitoring PM and annoyance tracking in construction, adapting to the local context in order to identify real benefits for the construction site
