| dc.description.abstract | Air pollution caused by motor vehicles has become a serious issue in many
urban areas. Emissions from vehicle exhausts have received due attention, but there
is another component that also contributes to air pollution, namely road dust
originating from brake wear, tire abrasion, and road surfaces. This research provides
an in-depth understanding of road dust composition and its impact on air quality and
public health. The findings reveal that road dust contains heavy metals such as iron
(Fe), manganese (Mn), and aluminum (Al) with concentrations of approximately
25.8167 ppm, 15.0585 ppm, and 713.6148 ppm, respectively. The particulate levels of
road dust reach 637.27985 μg/Nm3, exceeding the permissible limits and potentially
posing negative health effects on humans. SEM-EDX and XRF analyses unveil diverse
morphologies and compositions of road dust, including other elements like magnesium
(Mg), silicon (Si), and Calsium (Ca). These results reinforce the understanding of air
pollution originating from road dust and highlight the necessity for more effective
pollution control measures. This research bears significant importance in efforts to
mitigate air pollution and safeguard public health. The outcomes can serve as a
foundation for the development of more effective air pollution management strategies
and contribute substantially to awareness of heavy metal risks in road dust. | en_US |
