“…For Pb, the available Pb in RS was higher than that in NRS from V4 to R4, irrespective of CM application rates (Figure ), which suggests that the soybean root activity induced the solubility of stabilized Pb. Arshad et al also reported that root-induced changes were responsible for the modification of Pb of organic species into available Pb, and these changes mainly derived from the acidification, which is also detected in the present study, and increased dissolved organic carbon in the rhizosphere . However, similar to Zn, CM application shifted the available Pb to ORG-bound Pb but with or without effects on soybean growth.…”

To characterize the dynamic mobilization of heavy metals (HM) in a crop-soil system affected by cattle manure (CM) application, soybean [Glycine max L. Merr. cv. Toyoharuka] crops were exposed in a chronological pot experiment to three CM application rates and sampled at two vegetative stages and two reproductive stages. A sequential extraction procedure for metal fractionation, soil pH, microbial activity, and plant HM uptake was determined. In non-rhizopshere soil, with CM application a liming effect was detected, and increased microbial activity was detected at the reproductive stage. CM application shifted Cd from available state to oxide-bound pool in non-rhizosphere soil; however, shifts in Cd from an oxide-bound pool to the available state were observed in rhizosphere soil. CM application stabilized the available Zn and Pb to oxide-bound Zn and organic-bound Pb in both non-rhizosphere and rhizosphere soils, and the stabilizing degree increased with higher CM application rates. The promoted Zn immobilization in the rhizosphere was due to the liming effects induced by added CM that counteracted the root-induced acidification. On the basis of a stepwise multiple regression analysis, the shift of Cd and Pb fractionation was mainly related to microbial activity. Adding manure inhibited Zn and Pb uptake but promoted Cd uptake by soybean, and a greater influence was detected at the reproductive stage, at which CM application increased the root Cd-absorbing power but did not significantly affect the Zn- and Pb-absorbing powers. In an agricultural context, long-term CM application, even at the recommended rate of 10.13 Mg ha, may cause a soybean Zn deficiency and high Pb accumulation in Haplic Fluvisols, although CM is often considered as an environmentally friendly fertilizer.

“…Sample preparation for ICP-OES analysis was performed with some modification in the method reported earlier. 25 In short, 5 mL of 65% HNO 3 (Merck) was added to 20 mg of powdered grain sample, which was then heated at 80 °C. Subsequently, 3 mL of 35% H 2 O 2 (Merck) was added, and samples were allowed to react overnight.…”

Plants have the natural ability to withstand stress conditions through metabolic adjustments. The present study aimed at investigating the effects of titanium dioxide nanoparticles (TiO NPs) application (0, 25, 50, 150, 250, 500, and 750 mg kg) in phosphorus-deficient soil in terms of growth responses, P contents, and metabolic alterations in rice. TiO NPs application increased shoot length up to 14.5%. Phosphorus contents in rice roots, shoots, and grains were increased by 2.6-, 2.4-, and 1.3-fold, respectively, at 750 mg kg of TiO NPs. Gas chromatography-mass spectrometry (GC-MS)-based metabolomics revealed increased levels of amino acids, palmitic acid, and glycerol content in grains resulting from plants grown in 750 mg kg TiO NPs-treated soil. Furthermore, no translocation of TiO NPs from the treated soil to rice grains was detected by inductively coupled plasma-optical emission spectrometry (ICP-OES), which suggests no risk of TiO NPs intake via grain consumption. The observed data indicates the strong relationship among NPs application, P contents, and metabolic alterations.

“…The physical speciation of Pb, derived from extended X‐ray absorption fine structure (EXAFS) spectroscopy, allows the form of Pb (adsorbed, absorbed, complexed, precipitated, coprecipitated, or in the form of pure salt or pure oxide) to be assessed in the solid soil phase (Manceau et al, 1996). In contaminated soils, Pb was found to be associated with a variety of species, including organic matter (OM) and iron (Fe) (oxyhydr)oxides, or present as chloropyromorphite [Pb 5 (PO 4 ) 3 Cl], lead carbonate (PbCO 3 ), lead oxides (PbO), and lead sulfate (PbSO 4 ) (Morin et al, 2001; Hashimoto et al, 2009; Juhasz et al, 2014; Sanderson et al, 2015; Arshad et al, 2016). Lead speciation probably depends primarily on the contamination source and level, the age of contamination, and the physicochemical parameters of the soils.…”

Lead (Pb)-contaminated sites that resulted from past mining and smelting activities still pose toxicological and ecotoxicological issues worldwide. A large body of research has been dedicated to evaluating the contamination and proposing mitigation strategies for recently contaminated sites (from the 19th century until the present). The possible impact of older contaminations has been much less investigated. The present study focuses on soils affected by Pb-silver mining and smelting activities during the 15th to 18th centuries. A combination of sequential extractions and X-ray absorption spectroscopy was used to determine the Pb fractionation and speciation in these soils. Despite the long passage of time, Pb was still highly available (1 and 6% of Pb present in the exchangeable fraction and 46 to 71% in the reducible fraction) and mostly present as Pb sorbed on iron (oxyhydr)oxides. Galena (lead sulfide, PbS) was observed in a soil sample from a kitchen garden, suggesting the recent use of smelter slags as soil amendments. This study shows that Pb is still highly available on this site after almost five centuries, probably because of the acidic character of the soil and the soil composition.
