چکیده مقاله:

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urban areas of Sanandaj, Iran. For this purpose, sampling points were selected on different roads including primary roads, high roads, and main roads. The geographic coordinates of sampling points were recorded by the Global Positioning System (GPS). The geoaccumulation index (Igeo) and integrated pollution index (IPI) were used to present the heavy metal contamination levels. The results obtained by the geoaccumulation index suggest that the roadside dust samples were moderately contaminated with Ni and Cr, moderately to heavily contaminated with Pb and Cd, and heavily to extremely contaminated with As and Zn. The assessment of the data shows that 92% of all roadside dust samples had moderate pollution levels with an IPI of higher than 2, indicating that roadside dust in Sanandaj County has moderately been polluted by anthropogenic emissions. In order to compare the heavy metal concentrations in different parts of Sanandaj County, each heavy metal contamination was interpolated in a geographical information system (GIS). Heavy metal distribution maps showed the different hotspots of each pollutant that indicated high traffic density and industrial centers as the important factors affecting their concentrations in Sanandaj County.

Noise pollution and its spatial distribution in urban environments (case study: Yazd city, Iran)

This study focuses on identifying source and frequency of noise pollution in Yazd, Iran. For data collection, we used two approaches: First we selected 55 monitoring stations for 122 km grid network; the distance between two stations was 2 km. Then, at the same time, we measured the sound pressure level (SPL) at main roads; the distance between two monitoring stations in this case was 1 km. Aft...

Assessment of Spatial Distribution and Pollution with Heavy Metals in Roadside Soils along Xi’an-baoji Highway in Northwest China

Xi’an-Baoji Highway is one of the oldest and most important highways in northwest China. In this study, the concentrations (0-20 cm) of Pb, Zn, Cu and Cr at 5-1000 m distances in the roadside soils along Xi’an-Baoji Highway were experimentally determined to analyze their spatial distribution and evaluate their contamination levels. The spatial distribution (mg·kg) of Pb, Zn, Cu and Cr at 5-1000...

Monitoring of heavy metal levels in roadside dusts of Thessaloniki, Greece in relation to motor vehicle traffic density and flow.

In recent years, the level of heavy metal pollution in urban areas has been of considerable concern. The principal source has been attributed to the motor vehicle and increasing inner city congestion, which has lead to a change and enlargement of transport stop-start zones. These areas of high traffic density are associated with an increased release of heavy metals into the adjacent residential...
