“…1), redox potential, total metal contents, and CEC (Chlopecka 1996;Imai et al 2002;Wang et al 2012a). Heavy metals like Cu and Zn show a significantly negative correlation with pH (García et al 2009;Wang et al 2013a), while soil OM effects vary from metal to metal Khan et al 2015). The aging factor and other soil properties are the main factors affecting the bioavailability of heavy metals (Ahmad and Goni 2010; Smolders et al 2009).…”

“…Plant contamination with heavy metals may occur through soil-plant, water-plant, and air-plant interfaces; however, soil-plant interface is the major source of plant metal accumulation. Literature shows that there is a strong relationship between heavy metals in soil and food crops (Bini et al 2012;Khan et al 2015). In general, the bioavailability of heavy metals depends on the amount of exchangeable metals in soil.…”

“…Biological organisms are incapable to degrade metals because of their nonbiodegradable nature and long half-life, and they persist in their body parts and environment leading to health hazards (Amaral and Rodrigues 2005;Nabulo et al 2011). Heavy metals have the capability to move from contaminated soil and water and bioaccumulate in vegetables causing health risks (Stasinos and Zabetakis 2013;Rattan et al 2005;Khan et al 2015).…”

“…Soil pH has significant effects on availability and accumulation of heavy metals in the edible parts of plants (Hu et al 2013;Wang et al 2013a). Similarly, CEC and OM have negative impact on the mobility and bioavailability of heavy metals like Pb (Arshad et al 2008;Ding et al 2013;McLaughlin et al 2011;Khan et al 2015). Cd toxicity to the soil environment is well known; it is a toxic heavy metal and causes toxicity even at low concentration.…”

Heavy metal contamination is a globally recognized environmental issue, threatening human life very seriously. Increasing population and high demand for food resulted in release of various contaminants into environment that finally contaminate the food chain. Edible plants are the major source of diet, and their contamination with toxic metals may result in catastrophic health hazards. Heavy metals affect the human health directly and/or indirectly; one of the indirect effects is the change in plant nutritional values. Previously, a number of review papers have been published on different aspects of heavy metal contamination. However, no related information is available about the effects of heavy metals on the nutritional status of food plants. This review paper is focused upon heavy metal sources, accumulation, transfer, health risk, and effects on protein, amino acids, carbohydrates, fats, and vitamins in plants. The literature about heavy metals in food plants shows that both leafy and nonleafy vegetables are good accumulators of heavy metals. In nonleafy vegetables, the bioaccumulation pattern was leaf > root ≈ stem > tuber. Heavy metals have strong influence on nutritional values; therefore, plants grown on metal-contaminated soil were nutrient deficient and consumption of such vegetables may lead to nutritional deficiency in the population particularly living in developing countries which are already facing the malnutrition problems.

“…However, studies about organic amendments not only focus on being a way to improve soil fertility but also are proposed for the remediation of heavy metal contaminated soils. Organic amendments have been used to either mobilize or immobilize heavy metals in contaminated soils (Ahmad et al 2015;Khan et al 2015). For the mobilization, metals are released into the soil and subsequently removed through native plant species.…”

The application of organic amendments into heavy metal contaminated soil is considered as an environmentally friendly technique to promote the potential of phytoremediation. A pot experiment was carried out to evaluate the effect of humic substances on growth, cadmium (Cd) accumulation and phytostabilization potential of the mining ecotype (ME) and the corresponding non-mining ecotype (NME) of Athyrium wardii (Hook.) grown in Cd-contaminated soils. The addition of the humic substances demonstrated great promotion for the growth and Cd uptake of ME. Both plant biomass and Cd concentration significantly increased with the increasing application of the humic substances up to 100 g kg(-1), beyond which no significant change of underground part biomass and Cd concentrations in underground part of A. wardii was observed. The maximum Cd concentration in underground part of ME was 180 mg kg(-1) when 150 g kg(-1) humic substances were applied. The ME showed greater Cd accumulation capability in underground part (0.47-0.68 mg plant(-1)) than that of NME (0.27-0.45 mg plant(-1)). Increasing bioaccumulation coefficient (BCF) values of A. wardii was observed with increasing application of the humic substances. The BCF values of ME were higher than those of NME. However, the use of the humic substances exhibited little impact on translocation factors (TFs) of ME, and the TF values of ME were less than NME. Furthermore, the application of the humic substances improved the remediation factors (RFs) of A. wardii. The RF values in underground part of ME ranging from 0.73 to 0.91 % were apparently higher than those of NME. These results indicated that the humic substances can be a potential candidate for enhancing the phytostabilization of A. wardii grown in Cd-contaminated soils.
