“…The present study suggests that the concentration of Pb was naturally low in the fluviatile, alluvial deposits and most of the metal occurred in the unavailable form. This finding is in agreement with the general findings, that Pb is highly immobile in soils and has high affinity for soil organic matter [19][20][21]. According to Adriano [18] , organic matter and clay are the dominant constituents contributing to Pb adsorption.…”

Abstract. The present study was carried out to determine the concentration and distribution status of some heavy metals (Pb, Cd, Cu and Zn) in the paddy field soil fractions of MADA in the state of Kedah, Malaysia. Five replicate samples were randomly collected from five paddy fields in the MADA area of Jitra. The heavy metals in the soil were extracted using sequential extraction method that was presented by Badri and Aston [1], which consisted of four different fractions using different reagents. The first fraction of extraction is the easily leachable and freely exchangeable fraction (ELFE), which uses ammonium acetate (NH 4 CH 3 COO). The second fraction is acid reduction fraction (AR), which uses hydroxylamine chloride (NH 2 OH_HCl), while the third fraction of extraction called the organic oxidation fraction (OO) was carried out using the combination of hydrogen peroxide (H 2 O 2 ), and ammonium acetate (NH 4 CH 3 COO). The last fraction called the resistant fraction uses concentrated nitrate acid (HNO 3 ) and perchlorate acid (HClO 4 ). Generally, all the paddy soils in this study contained low levels of Pb, Cd, Cu and Zn concentration compared to the other paddy soils. The result showed that the concentration of heavy metals in the studied area was in the following decreasing order i.e.: Pb > Zn > Cu > Cd. The results also showed that the concentration of heavy metals in the paddy soil fractions were mainly concentrated in the RR fraction except for Pb, which was at the highest level in the OO fraction, whilst Cd was more evenly distributed throughout the whole soil fraction. In general, Pb was the highest metal concentration found in the OO fraction followed by Zn in the RR fraction of the soil fractions.

“…Naturally, the bioavailable heavy metal will become a growing concern should its concentration exceed the threshold limit. In Peninsular Malaysia, heavy metal speciation studies have been carried out in selected agricultural soils (Habibah et al, 2011;Khairiah et al, 2006;Khairiah et al, 2009a;2009b;2009c;2012). However, a comprehensive understanding of manganese speciation in agricultural soils of different origins has never been compared.…”

Manganese speciation in selected agricultural soils of Peninsular Malaysia is discussed in this study. Manganese concentration in the Easily Leacheable and Ion Exchangeable (ELFE), Acid Reducible (AR), Organic Oxidizable (OO) and Resistant (RR) fractions of soils developed on weathered rocks, soils of mixed nature, alluvium and peat deposits are described. The total manganese concentration in soils developed on weathered rocks was found to be higher than that in soils of mixed nature, alluvium and peat deposits because of the occurrence of resistant manganese oxide at the topsoils. Manganese speciation in paddy soils is influenced by the redox condition resulting from the alternate flooding and drying of the soils. Under reducing conditions, this metal tends to get dissolved and be available for plant uptake. Upon oxidation, manganese is precipitated into the acid reducible fraction as poorly crystalline manganese oxide and hydroxide and/or the resistant Fe-Mn mottles. In non-paddy cultivated alluvial soils, manganese speciation varies widely and is less understood. For the non-paddy cultivated peat soils, manganese is mainly associated with organic material, as indicated by the high manganese concentration in the OO fraction.

“…In tropical agricultural soils, the accumulation of HMs mainly occurs through the application of pesticides, inorganic fertilisers, biosolids and organic fertilisers, such as pig manure and poultry litter (Fontes and Gomes 2003;Andrade et al 2014;Mishra et al 2009;Khairiah et al 2006;Uchimiya et al 2012;Huang and Jin 2008). Among inorganic fertilisers, phosphate fertilisers are considered the major source of HMs in agricultural soils (Kabata-Pendias 2011; Atafar et al 2010;Huang and Jin 2008;Thawornchaisit and Polprasert 2009).…”

“…In general, the prolonged use of phosphate fertilisers, biosolids and pesticides in tropical soils has substantially increased the natural levels of Cd, Cr, Cu, Pb and Zn in soils and crops, whereas other metals, such as As, Ba, Hg, Mo, Ni, Mn and Fe, are less reported and studied, most likely due to less significant changes or more regional accumulations (dos Anjos and Mattiazzo 2000; Appel and Ma 2002;Cai et al 2007;Atafar et al 2010;Camilotti et al 2012;Andrade et al 2014;Araújo et al 2014;Doelsch et al 2006;Fernandes et al 2007a;Fontes and Gomes 2003;Gonçalves Júnior et al 2000;Huang and Jin 2008;Khairiah et al 2006;Maftoun et al 2005;Mishra et al 2009;Nogueira et al 2013;Parkpain et al 2000;Parkpian et al 2003;Sharma et al 2009;Soumare et al 2003;Udom et al 2004). In Brazil, the application of biosolids from a sewage treatment station on red Latosol (Oxisol) for 12 consecutive years resulted in a significant accumulation of HMs, such as As, Ba, Cd, Cr, Cu, Hg, Ni, Pb and Zn.…”
