“…However, the average Cr, Pb, Ni, and Zn concentrations in the wastewater-and groundwater-irrigated areas were lower than the upper threshold of the National Standard for Soil Environment Quality (90 mg/kg for Cr, 35 mg/kg for Pb, 40 mg/kg for Ni, and 100 mg/kg for Zn). These results correspond with the findings of Avci and Deveci, who observed that the mean Cr, Ni, Pb, and Zn concentrations were somewhat greater in the wastewaterirrigated soil samples than in the control samples [46]. Tiwari et al reported greater metal concentrations (Fe > Mn > Zn > Cd > Cu > Pb > Cr) in a soil that was irrigated with effluent than in a soil that was irrigated with tube well water [47].…”

Soil and plant samples were collected from Tongliao, China, during the maize growth cycle between May and October 2010. Heavy metals, such as Cr, Pb, Ni, and Zn, were analyzed. The concentrations of Cr, Pb, Ni, and Zn in the wastewater-irrigated area were higher than those in the topsoil from the groundwater-irrigated area. The concentrations of metals in the maize increased as follows: Pb < Ni < Zn < Cr. In addition, Cr, Pb, and Ni mainly accumulated in the maize roots, and Zn mainly accumulated in the maize fruit. The results of translocation factors (TF) and bioconcentration factors (BCF) of maize for heavy metals revealed that maize is an excluder plant and a potential accumulator plant and can serve as an ideal slope remediation plant. In addition, the increasing heavy metal contents in soils that have been polluted by wastewater irrigation must result in the accumulation of Cr, Pb, Ni, and Zn in maize. Thus, the pollution level can be decreased by harvesting and disposing of and recovering the plant material.

“…Also, corn seedlings have been used to bio-accumulate Pb in contaminated soil [68]. Significant levels of Pb get to plants and the food chain through atmospheric deposition from industrial waste and smokestack emissions, vehicle exhaust and degradation, and agricultural uses of fertilizers and pesticides [69]. It has been shown that vegetative mycelia and mushroom fruit bodies accumulate heavy metals from their substratum [70], and in high proportions too [71].…”

IntroductionPeanut shells (PS) are abundant agro-industrial waste products that are recalcitrant to degradation under natural conditions [1]. The increasing expansion of peanut production has led to accumulation of large quantities of these shells all over the world. In the US alone, peanut production increased by 45% between 2011 and 2012, bringing production to 3.04 million metric tons [2]. Globally, 45.6 million metric tons of peanuts are produced annually [3]. It has been estimated that for every kg of peanuts produced, 230-300 g of peanut shells are generated [4]. Therefore, as much as 13.7 million metric tons of peanut shells are churned out every year, most of which are dumped into the environment or burned [5,6]. Peanut shells are a renewable resource that could be targeted for purposeful use in the food, feed, paper and bioenergy industries. However, as yet, few if any value-added uses exist for them [7].Over the years, various attempts to utilize peanut shells have been made. Small fractions were incorporated into animal feed, especially for cattle [8], while some authors have experimented on their use as dietary fiber for humans [9]. Other non-food research trials include uses in pulp production [10], feedstock for bioethanol production [11,12], particle board component [13], mulch and activated charcoal [7]. However, the major drawback to their use in large scale industrial operations is the high lignin content.Much like other agricultural lignocellulolysic biomass, peanut shells are composed mainly of lignin, cellulose and hemicellulose. Lignin, a complex polymer, is the most recalcitrant component of plant biomass [14] and binds tightly to, and provides a physical seal around, cellulose and hemicellulose [11,[15][16][17][18], thereby protecting them against attack by hydrolytic enzymes. The restricted bioavailability of these sugars and other components is thought to be largely physical, with lignin molecules reducing the surface area available to enzymatic penetration and activity [19]. In order to gain access to the sugars in cellulose and AbstractWorld consumption of peanuts has increased tremendously, resulting in abundance of peanut shell waste. The high lignin content of peanut shells limits their bioconversion to useful products or recycling. Therefore, the synergy in co-substrating peanut shells (PS) and cornstalks (CS) to enhance biodegradation was evaluated. Various compositions of peanut shells and cornstalks (% dry weight) herein called co-substrate -90PS:10CS, 75PS:25CS, 50PS:50CS, 25PS:75CS, 10PS:90CS, and two controls Cont1-100PS and Cont2-100CS were studied under solid state fermentation (SSF) with a white rot fungus, Pleurotus ostreatus for 120 days. A two-factorial experiment in a completely randomized design (CRD) was used. Results showed that substrate composition and fermentation time were important variables in substrate degradation. Lignin degradation, losses in organic matter, cellulose and hemicellulose increased with time. Increasing the composition of CS in co-substrates...

“…Trace elements such as As, Cr, Pb, and Sb are highly toxic to the environment. Moreover, the irrigation of soils with water that contains high concentrations of trace elements not only results in the transfer of these elements from the water to the soil, but also increases the bioavailability of these elements for plants [ 4 ]. In Table 2 , it can be observed that the concentrations of these elements in the irrigation water that was analyzed in this study are above the recommended maximum concentration for irrigation water [ 26 , 27 ].…”

“…The composition of these elements in nature depends on their local mineralization, interactions with the environment, soil, and water, and the specific biota of each site [ 2 ]. The environmental problems caused by trace elements are the result of their natural mobilization, lithology, weathering reactions, biological activity, volcanic emissions, rock solubilization, and anthropogenic activity [ 3 , 4 ]. Trace elements are directly emitted into the atmosphere and the soil, due to the emission of mining residues, industrial emissions, the use of pesticides and fertilizers, fossil fuels, and wood preservatives [ 4 ].…”

The aim of this study was to quantify major and trace elements in the water, soil, and plants (Carya illionensis) in an agricultural area; and to determine the health risks associated with the walnuts ingestion by calculating the risk quotient. Samples of water, soil, tree leaves, and walnuts were collected; in total, 135 samples were analyzed. Physicochemical parameters were obtained in irrigation water and soil samples. Elemental measurements were performed in an ICP, -OES and -MS. In addition, the distribution coefficient (soil–water), transfer factor (soil–plant), and hazard quotient were evaluated. In the irrigation water, As, Cr, and Pb, showed concentrations above the maximum allowable limits. Likewise, high concentrations of As, Cr, Pb, and Sb were found in tree leave samples, indicating a possible tendency of hyperaccumulation of those elements. Furthermore, Cr concentrations in walnuts were high by far than the reference value (FAO/WHO). A possible competition between chemical congeners were detected from transfer factors. Although, Sb concentrations in walnuts were also high, and no legislation for it in fruits exists. The hazard risk quotient for Sb did indicate a potential health risk. Finally, it is important to consider that the health risk increases when exposure through consumption takes place over a prolonged period of time, even in low concentrations.
