Abstract
Building activity is a significant source of atmospheric contamination by ultrafine dust. Cognizant of this fact, those active in the use and recycling of construction materials must be aware of the risks associated with exposure to nanoparticles (NPs) and ultra-fine particles (UFPs), as well as the associated health impacts. This work analyzed NPs and UFPs generated in a small building-material recycling company using high-resolution electron microscopes and X-ray Diffraction. A self-made passive sampler (LSPS) that can obtain particulate samples without physical and morphological changes, especially where there is a suspension of particulate material, was used in this study. A total of 96 particulate samples, using the LSPS for three months in four seasons, were collected during the study. Thus, the dry deposition of the particles, which are considered highly harmful to human health, was found in each of the four seasons of the year. It is suggested that for future research, the toxicological evaluations of the particulates in the construction industry should be investigated through the consideration of measures to control and mitigate the health risks of workers regarding exposure to NPs and UFPs.
Highlights
The need to breathe contaminant-free air is essential for long-term health benefits.This need has been compromised, especially with the beginning of the industrial revolution, and it is a matter of concern in countries such as China, the US, andIndia, as many studies point out [1,2,3,4]
Studies on personal exposure to ultra-fine particles (UFPs) and NPs can assist in mitigating the associated health risks of exposure to indoor contaminants such as particulate materials
A systematic approach was used to assess the chemical, mineralogical, and morphological composition of NPs and UFPs produced in a construction waste recycling company
Summary
The need to breathe contaminant-free air is essential for long-term health benefits.This need has been compromised, especially with the beginning of the industrial revolution, and it is a matter of concern in countries such as China, the US, andIndia, as many studies point out [1,2,3,4]. The need to breathe contaminant-free air is essential for long-term health benefits. This need has been compromised, especially with the beginning of the industrial revolution, and it is a matter of concern in countries such as China, the US, and. There are some studies on the atmospheric contamination of outdoor air in areas of civil construction, there are no studies concerning indoor air in construction waste recycling companies, even though the study of atmospheric contaminants is highly relevant to indoor atmospheres [6,7,8] For this reason, new assessments are necessary to provide more scientific information about the occurrence, composition, morphology, and distribution of contaminants in areas of construction material recycling which take place in indoor air, as well as the exposure of workers and populations as a result of such activity. Building and demolition rejects (BDR) comprise the greatest portion of solid rejects globally. In European countries, building and demolition actions produce around 900 Mt
