“…(Zheng et al, 2004). This value was about 5.4, 4.3, 7.1, 2.5, 1.4, 1.1, 1.7, 38.3 and 6.8 times higher that of Huelva (2001) (Sanchez-Rodas et al, 2007), Huelva (2002 (SanchezRodas et al, 2007), Taiwan (2003 (Tsai et al, 2003), China (Wu et al, 2003), Serbia (2005) (Serbulaa et al, 2010), Serbia (2006) (Serbulaa et al, 2010), Serbia (2007) (Serbulaa et al, 2010), Greece (2008) (Tsopelas et al, 2008) and China (2009) (Lu et al, 2009), respectively. From the point of view of PM 2.5 , the results indicated that the maximum average particulate concentration for As was occurred at Spanish (2002) (average, 7.9 ng/m 3 ) (Sa'nchez de la Campa et al, 2008).…”

This study investigated the feasibility of monitoring arsenic (As) levels in total suspended particulates (TSP), in both dry deposition and dry deposition flux at five sampling sites located in central Taiwan during the years of 2009-2010. Experimental results indicate that the average As concentration in TSP and dry deposition was highest in Quan-xing (industrial) and lowest in Gao-mei (wetland). The mean As composition in TSP was highest in Hei-mei (residential) and lowest in Gao-mei (wetland). The average highest arsenic (As) of seasonal concentrations and compositions in TSP, dry deposition were occurred in winter and fall denotes that fossil fuel combustion by Taichung thermal power plant (TTPP) emissions and heating by household were the main reasons responsible for the high data values measured. Atmospheric concentrations of arsenic (As) were analyzed by a ICP-MS (Perkin Elmer Sciex ELAN DRC II). Finally, best-fit model can be used successfully in the prediction of ambient air pollutants around suburban/coastal, downtown, residential, industrial and wetland areas.

“…Recently, it has been widely applied in contamination assessments of heavy metals in soil, dust, water, and sediment (Bhuiyan et al 2010;Lu et al 2009;Suthar et al 2009). In this study, the geoaccumulation index was calculated using Equation (2):…”

Rice is a staple food by an increasing number of people in China. As more issues have arisen in China due to rice contaminated by cadmium (Cd), Cd contamination in arable soils has become a severe problem. In China, many studies have examined Cd contamination in arable soils on a national scale, but little studies have focused on the distribution of Cd in paddy fields. This study explored the spatial pattern of Cd in paddy soils in China, made a preliminary evaluation of the potential risk, and identified the most critically contaminated regions based on the domestic rough rice trade flow. The results showed that Cd concentrations in paddy soils in China ranged from 0.01 to 5.50 mg/kg, with a median value of 0.23 mg/kg. On average, the highest Cd concentrations were in Hunan (0.73 mg/kg), Guangxi (0.70 mg/kg), and Sichuan (0.46 mg/ kg) provinces. Cd concentrations in paddy soils in central and western regions were higher than those in eastern regions, especially the southeastern coastal regions. Of the administrative regions, Cd standard exceedance rate was 33.2 %, and the heavy pollution rate was 8.6 %. Regarding to Cd of paddy soil, soil environmental quality was better in Northeast China Plain than in Yangtze River Basin and southeastern coastal region. Mining activities were the main anthropogenic pollution source of Cd in Chinese paddy soil. Based on rice trade, more of the Chinese population would be exposed to Cd through intake of rice produced in Hunan province. Certain regions that output rice, especially Hunan province, should be given priority in the management and control of Cd contamination in paddy soil.

“…Hg concentration in Ahvaz street dust is high in comparison to many other cities in the world (Fig .4). For example, whilst the mean concentration of Hg in the all samples in the study area is lower than Aviles, Spain (Lu et al 2009), meanwhile, it was higher than that in Beijing, China (Xinmin et al 2006 …”

Mercury as a toxic element and its associated health hazard has been an important topic of research for urban pollution for many years. In this paper, the spatial distribution, pollution assessment, and health risk associated with Hg in roadside dust 96 street dust samples, representing differing land uses have been investigated. Land uses included residential areas (RA), industrial areas (IA), public gardens (PG), roadside areas (RS) and suburban areas (SA) in the city of Ahvaz, Iran were investigated. Compared with other cities, the concentration of Hg in Ahvaz was considerably higher with a mean value of 2.53 mg.kg . Residential areas exhibited higher Hg in street dust than other areas, as demonstrated by spatial mapping illustrating hot-spots associated with old urban areas with high residential density, high volume traffic of roadside areas, and industrial districts: including oil-drilling activities, steel smelting related industries, and small industrial towns around Ahvaz. However, Hg concentrations in street dust near to the public gardens (PG) and suburban areas (SA) were not at elevated levels compared other land uses investigated in this study. A health risk assessment model of non-carcinogenic effects was evaluated for both children and adults. The HQ values also revealed that the main exposures route for children and adults decreased as follows: vapour>ingestion> dermal contact> inhalation. The Hazard Index (HI) in each area is less than the safe level (HI≤1) for children and adults, but higher for children. The HI value decrease as the following order: RS>IA>RA>SA>PG, which indicates potentially serious health hazards for children in the study areas.
