“…Likewise, the use of alkaline CFA is likely to help in the remediation of metal contaminated sites by immobilization of metals via raising soil pH and formation of stable metal phases (Hooda and Alloway, 1996;Hooda et al, 1997;Mench et al, 2006;Hooda, 2010;Lopareva-Pohu et al, 2011;Kim et al, 2012;Skousen et al, 2013;Ram and Masto, 2014). However, it is important that such a use of CFA should not lead to further elevation of total metal levels in the soils.…”

“…The use of alkaline CFA may offer an alternative way of metalcontaminated soil remediation/management via their immobilization (Kim et al, 2012). This was demonstrated in a study where CFA was used to stabilize a Pb-and Cu-contaminated soil (Kumpiene et al, 2007).…”

“…Even though the development of analytical methods for measuring the bioavailability of heavy metal(loid)s in agricultural soils was rare in Korea, various assessment techniques were already developed worldwide. Bioavailability of metal(loid)s in agricultural soils was determined mainly by the concentration of metal(loid)s, the species and fractions of a specific metal(loid), and the physico-chemical properties of soils (Ruby et al, 1993;Geebelen et al, 2002;Kim et al, 2012a).

The Codex Committee of Contaminants in Food (CCCF) has been discussing a new standard for arsenic (As) in rice since 2010 and a code of practice for the prevention and reduction of As contamination in rice since 2013. Therefore, our current studies focus on setting a maximum level of As in rice and paddy soil by considering bioavailability in the remediation of As contaminated soils. This study aimed to select an appropriate single chemical extractant for evaluating the mobility of As in paddy soil and the bioavailability of As to rice. Nine different extractants, such as deionized water, 0.01 M Ca(NO 3 ) 2 Woo-Ri Go, Seon-Hee Jeong, Anitha Kunhikrishnan, Gyeong-Jin Kim, Ji-Hyock Yoo, Namjun Cho, Kwon-Rae Kim, Kye-Hoon Kim, and Won-Il Kim 465 IntroductionThe Ministry of Environment established the criteria of soil contamination for heavy metal(loid)s in the agricultural fields designated by the Soil Environment Conservation Law in 1996 (MOE, 1996). The Ministry of Food and Drug Safety also established the criteria of 0.2 mg/kg for cadmium (Cd) in polished rice in Korea (KFDA, 2000). Recently, our regulations for agricultural environment including soil, irrigation water, agricultural materials (fertilizer and compost etc.), and agricultural products are being gradually reinforced (KFDA, 2011;MOE, 2010a). The CCCF (Codex Committee of Contaminants in Foods) have been under discussion on the maximum levels for arsenic (As) in polished rice since 2010 (FAO/WHO, 2014).In Korea, the standard method of analyzing heavy metal(loid)s contamination in soils is by aqua regia digestion (MOE, 2010b). This method is acceptable to evaluate the environmental burden of pollutants to the soil and to decide the proper environmental management and human safety. However, this method is not useful for assessing the metal bioavailability to crops. In order to minimize the risk of heavy metal(loid)s to the agricultural environment, crops, livestock, and humans exposed during the agricultural activities, considering bioavailability for the remediation of heavy metal(loid)s is necessary for agro-food safety (Naidu et al., 2003;Heemsbergen et al., 2009;Kim et al., 2009;Salazar et al., 2012;Bolan et al., 2014). Even though the development of analytical methods for measuring the bioavailability of heavy metal(loid)s in agricultural soils was rare in Korea, various assessment techniques were already developed worldwide. Bioavailability of metal(loid)s in agricultural soils was determined mainly by the concentration of metal(loid)s, the species and fractions of a specific metal(loid), and the physico-chemical properties of soils (Ruby et al., 1993;Geebelen et al., 2002;Kim et al., 2012a). Various single and stepwise sequential extraction methods were suggested to estimate the bioavailability of heavy metal(loid)s in agricultural soils. The Soil Environment Conservation Law recommended the use of 0.1 M HCl for cadmium (Cd), lead (Pb), copper (Cu), chromium (Cr), nickel (Ni), and zinc (Zn) and 1.0 M HCl for As to evaluate their bioavailability ...

“…Based on the above results, it might be a good soil management to control pH and OM concentration with soil amendments such as lime and compost to reduce phytoavailability of heavy metal (loid)s in arable soil located near industrial complex.

There are a number of industrial complexes which could be a source of heavy metal (loid)s contamination of arable soil in Gyeongnam province of South Korea. Heavy metal (loid)s accumulation of plant is more related to the concentration of plant available heavy metal (loid)s in arable soil than that of total heavy metal (loid)s. The objectives of this study were 1) to examine heavy metal concentrations in soils located near industrial complexes in Gyeongnam province and 2) to determine the relationship between concentration of plant available heavy metal (loid)s and chemical properties of soil. Soil samples were collected from 85 sites of arable lands nearby 7 industrial complexes in Gyeongnam province. Total heavy metal (loid)s concentration, available heavy metal (loid)s concentration, and chemical properties of collected soils were measured. The mean concentrations of arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) in the soils were 5.8 mg kg , respectively. Total concentration of Cd and Zn in arable soil located near ∇∇ industrial complex exceeded the warning criteria (4 mg kg -1 and 300 mg kg -1 for Cd and Zn, respectively) as described by in the soil environmental conservation Act of Korea. The concentration of plant available heavy metal (loid)s was negatively related to the soil pH and available Pb and Zn concentrations had relatively high correlation coefficient when compared with other heavy metal (loid)s. The concentration of plant available Pb and Zn was negatively related to that of organic matter (OM). Based on the above results, it might be a good soil management to control pH and OM concentration with soil amendments such as lime and compost to reduce phytoavailability of heavy metal (loid)s in arable soil located near industrial complex.
