Mapping of human health risks arising from soil nickel and mercury contamination

Spatial Eco-Risk Assessment of Heavy Metals in the Surface Soils of Industrial City of Aran-o-Bidgol, Iran

“…Geostatistics and Geographic Information System (GIS) mapping are powerful means utilized by numerous research studies to assess pollutants' spatial distribution and behavior in urban areas (Dayani and Mohammadi 2010;Mirzaei et al 2014a, b;Nezhad et al 2015;Qishlaqi et al 2009;Solgi et al 2012). Kriging is one of the most frequently applied interpolation methods in environmental studies (Dayani and Mohammadi 2010;Hani and Karimineja 2010;Karimi Nezhad et al 2014;Mirzaei et al 2014a;Mokhtari et al 2015;Yeganeh et al 2013).…”

“…Despite a few studies performed at different scales to investigate heavy metals pollution (e.g. Dayani and Mohammadi 2010;Dankoub et al 2012;Yeganeh et al 2013), and potential ecological risks (e.g. Mirzaei et al 2014a) in Iranian soils, there has been insufficient information on potential ecological risks threatening these soils over the last few decades.…”

Ecological risk of heavy metal hotspots in topsoils in the Province of Golestan, Iran

“…According to several works reported by Iranian studies (Amini et al (2005) The mean value of Ni in Golestan region (34.88 mg kg-1) exhibit lower contents than Iranian literature that range from 53 to 71 mg kg-1 (Dankoub et al, 2012;Naimi and Ayoubi, 2013;Solgi et al, 2012;Yeganeh et al, 2013). In Angouran region (NW Iran) Qishlaqi et al (2009) reported a mean value of 22.59 mg kg-1.…”

“…Irrespectively of the origin or contamination source, HMs can accumulate in crops and reach humans through the food chain (Burger, 2008;Rodríguez Martín et al, 2013a). In the last few decades, many soil pollution surveys on trace elements have been carried out on different scales and many studies are reported in the scientific literature (Amini et al, 2005;Rodríguez Martín et al, 2009;Weber and Karczewska, 2004;Yeganeh et al, 2013). However, very few research works have been conducted in developing countries such as Iran.…”

“…However, very few research works have been conducted in developing countries such as Iran. To date, several attempts have been made to determine the concentration of HMs in Iranian soils (e.g., Amini et al, 2005;Dankoub et al, 2012;Dayani and Mohammadi, 2010;Geranian et al, 2013;Ghaderian and Ghotbi Ravandi, 2012;Karimi et al, 2011;Nael et al, 2009;Naimi and Ayoubi, 2013;Parizanganeh et al, 2010;Qishlaqi et al, 2009;Yeganeh et al, 2013). Except for one recent study (Yeganeh et al, 2013), research works into HMs concentrations in Iranian soils on the provincial scale are lacking.…”
