“…Of importance among the plants examined were Panicum maximum, which is used in feeding livestock, and Lantana camara, which may be used for medicinal purposes. The results of our study are in agreement with other studies where plants that were collected around cement factories exhibited values that were above the WHO recommended limits [11,25,26]. Variations in the concentrations of trace metals in plants with the unwashed plant samples collected around a cement factory have significantly higher concentrations of trace metals such as those noted in our study [26].…”

“…The observed value for Zn and Cu around the cement factory may also suggest the effects of anthropogenic sources of these pollutants. A similar observation in the concentrations of Zn and Cu around a cement factory in Nigeria was also reported from a separate study [11] that attributed the presence of the trace metals to an anthropogenic source through dust emissions from the cement factory. Positive correlations were noticed for some of the trace metals such as Pb, Zn, Cu, Mn, Ni, Cr, and As (Table 6).…”

“…...where Ci represents the concentration of heavy metal i in soil while Si indicates the relevant standard value for this metal [11,17]. Soil contamination level, using Pi, was classified into four grades: Pi < 1 unpolluted, 1 ≤ Pi < 2 is regarded as slight pollution, 2 ≤ Pi < 3 regarded as medium pollution, and Pi ≥ 3 regarded as heavy pollution [18].…”

“…Most cement factories have been noted as potential sources of metals such as Hg, Zn, Pb, Cr, and Cd [8][9][10][11]. The effects and concentrations of the dust containing trace metals as pollutants vary and depend largely on technology employed from the cement industries to ameliorate environmental degradation.…”

“…In the present study, a significant negative correlation (P = 0.05) (r = 0.383) was found between Cr and Cd in the soil samples from the area surrounding the mega cement plant by studying the correlation between different metals. Furthermore, the presence of Cd in the soil to some extent can the emissions from cement production and a significant correlation with Pb and Cu (28). The results of a study on heavy metal pollution in soil and plants in the vicinity of the cement plant in Volta Region, Ghana, showed a positive correlation between soil and plant samples (excluding Zn and Ni) through analysis of heavy metals in soil and plants.…”

Received: December 2015, Accepted: January 2016Background: Soil pollution and accumulation of heavy metals in crops in industrial areas is one of the most important environmental issues threatening the life of plants, animals, and humans. The aim of this study was to determine the concentration of Cr and Cd in the soil and barberry plants in farms surrounding the Qayen Cement Company, South Khorasan Province, Iran. Materials and Methods: In this study, 8 soil samples were collected from a depth of 0-30 cm and 30-60 cm and 4 samples of barberry plant containing fruits and leaves in summer 2014. The concentrations of Cr and Cd in the samples were determined using atomic absorption spectrometry. Results:The maximum concentration of Cr and Cd was observed in the soil sample collected from a depth of 0-30 cm (95.10 and 1.32 mg/kg of soil, respectively). The concentration of Cr and Cd was higher in the fruits of barberry than the leaves; 18.58 mg/kg and 59.45 µg/kg, respectively, which are higher than the standard values. Transfer factor was calculated as less than 1 for all stations. Conclusions: According to obtained results, Qayen Cement Company has the greatest impact on plants in this region. The barberry fruit is the strategic product in Qayen; therefore, attention to and management of the impact of the cement factory on agricultural products is necessary.

This study was designed to determine the particle size distribution and develop road dust index combining source and transport factors involving road dust for dust pollution quantification in Rawang. Principal component analysis (PCA) was applied to identify possible sources of potentially toxic elements and spot major pollution areas in Rawang. The health risks (carcinogenic and noncarcinogenic) to adults and children were assessed using the hazard index and total lifetime cancer Risk, respectively. A total of 75 road dust samples were collected and particle sizes (1000, 500, 250, 160, 125 and 63 µm) were determined. Concentrations of potentially toxic elements (Cu, Cd, Co, Cr, Pb, Ni, Zn and As) in particle size of 63 µm were analyzed. The results demonstrated that the highest grain size of 250 µm has contributed almost more than 25% of atmospheric particulate pollution. The highest potentially toxic element concentration was Pb (593.3 mg/kg), whereas the lowest was Co (5.6 mg/kg). Road dust index output indicated that pollution risk fell into moderate levels in eastern and northern areas of Rawang. Similarly, PCA results revealed that potentially toxic elements (Cu, Cd, Pb, Zn, Ni and Cr) were linked with anthropogenic sources (urbanization process, industrial and commercial growth, urban traffic congestion) in northern and southern parts of Rawang. Cobalt and As concentrations were explained mainly from natural sources. Noncarcinogenic risk by hazard index value more than 1.0 was indicated for adults and children. Similarly, carcinogenic risk by total lifetime cancer risk value also showed carcinogenic risks among adults and children.
