“…The available Ni and Pb concentrations were within the ranges of critical levels of toxicity (0.03-5.34 mg kg −1 for DTPA Ni; 0.04-5.93 mg kg −1 for Mehlich-3 Ni; 0.44-39 mg kg −1 for DTPA Pb; 0.66-29 mg kg −1 for Mehlich-3 Pb) reported by Silva et al (2020), despite the lithogenic origin of these elements and the absence of pollution indicated by the total concentrations and the pollution indices. However, according to Silva et al (2020), the critical levels for these elements vary widely among soils and might not apply to the soils in the present study. Therefore, the absence of Ni and Pb pollution appears most plausible.…”

“…The available Cd concentrations (extracted either by DTPA or Mehlich 3) were above or close to the critical levels of toxicity (0.01-0.04 mg kg −1 ) reported by Silva et al (2020). However, contrary to pseudo-total Cd (Figure 2), the concentrations of DTPA and Mehlich-3 Cd (Figure 3) decreased significantly with depth, indicating a decreased risk by Cd pollution.…”

The application of cattle slurry to agricultural soils contributes to the circular economy, while enriching the soil in macro and micronutrients and organic matter. However, this practice can have deleterious environmental effects, by adding toxic metals and other contaminants. The pseudo-total concentrations of nine potentially toxic and trace metals (Fe, Mn, Zn, Cu, Ni, Co, Cr, Cd and Pb) as well as metals extracted by DTPA, Mehlich 3 and 0.01 M CaCl2 were determined in Galician (NW Spain) grassland soils regularly receiving cattle slurry. Four soil depths (0–5, 5–10, 10–20 and 20–40 cm) were sampled and analysed. The pollution condition was assessed by comparing the pseudo-total concentrations with generic reference levels for Galician soils and by using pollution indices. The results indicated the absence of soil pollution by Fe, Ni, Co, Cr and Pb and a situation of no pollution to moderate pollution by Mn, Zn and Cu. Cd was the element most frequently enriched in the studied soils according to the pseudo-total, DTPA and Mehlich-3 concentrations, while the extraction by CaCl2 pointed to no environmental risk. The study supports the lithogenic character of Fe, Ni, Co and Cr, the mixed lithogenic and anthropogenic nature of Mn, Zn and Cu and the anthropogenic origin of Cd in these soils. The latter element can be added by both the application of cattle slurry and inorganic phosphate fertilisers.

“…Heavy metal ions, such as Cd(II), Ni(II), Pb(II), Cr(VI), As (III), Cu(II), Hg(II), etc. are highly water soluble, toxic and have the ability to migrate that must be removed from wastewater before they are released into the environment [6,7]. Several conventional methods have been developed to remove them from wastewater as well as in water purification [8]: adsorption, ion-exchange, solvent extraction, chemical precipitation, membrane filtration, bio-adsorption, electrodialysis, coagulation and flocculation, flotation, and electrochemical treatment.…”

A Zeolitic imidazolate framework-8 (ZIF-8) was synthesized by the solvothermal method of zinc nitrate hexahydrate and 2-methylimidazole in DMF to remove Cd(II), Ni(II), and Pb(II) ions from aqueous solutions. The synthesized ZIF-8 was distinguished by XRD, FT-IR, BET, SEM, EDX, TEM methods. Several significant variables were optimized with response surface methodology (RSM) to obtain the highest removal of metal ions. According to the achieved results, the aqueous solution pH values of 6.5, 6.5, and 6.0, ZIF-8 dosages of 0.05, 0.06, and 0.05 g⸳L-1, and metal ions initial concentrations of 50, 60, and 60 mg⸳L-1 were chosen as the optimum amount of these variables for Cd(II), Ni(II), and Pb(II) ions adsorption from solution, respectively. The equilibrium time for metal ions adsorption was found at 50 min. Three-dimensional plots demonstrate relationships between the metal ion uptakes with the paired factors, which illustrate the behavior of the sorption system in a batch process. Based on the experimental results and model parameters, maximum adsorption efficiencies were achieved 89.76, 72 and 68.43% for Cd(II), Ni(II) and Pb(II), respectively. It can be suggested that the synthetized ZIF-8 has excellent potential as an effective adsorbent and used for heavy metal sorption from water environment.

“…However, exceeding the accumulation of Ni in plant tissues leads to toxicity in the plant and can negatively affect plenty of the plant's physiological and biochemical processes (Kosakivska et al 2021). High Ni concentrations indirectly cause increased reactive oxygen species (ROS) production in plant cells (Silva et al 2020). The high ROS generation in plant cells caused redox imbalance, disrupt enzyme activities, damage the structure of lipids and proteins, oxidative stress, and eventually cell death (Chaki et al 2020).…”

Salicylic acid (SA) and jasmonic acid (JA) as plant growth regulators (PGRs) have the potential to ameliorate plant development and tolerance to deleterious effects of toxic metals like nickel (Ni). Therefore, the current study was carried out to evaluate SA and JA's interactive effect on the root antioxidative response of two Alyssum in atum Nyár. populations against Ni-toxicity. Two A. in atum species under Ni-stress conditions (0, 100, 200, and 400 µM) were exposed to alone or combined levels of SA (0, 50, and 200 µM) and JA (0, 5, and 10 µM) treatments. Results showed that high Ni doses reduced the roots fresh weight (FW) in two populations than control; however, the use of external PGRs had ameliorated roots biomass by mitigated Ni-toxicity. Under Ni toxicity, SA and JA, especially their combination, induced high Ni accumulation in plants' roots. Moreover, the application of SA and JA alone, as well as combined SA + JA, was found to be effective in the scavenging of hydrogen peroxide (H 2 O 2 ) by improving the activity of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX) in both populations under Ni-toxicity. Overall, our results manifest that SA and JA's external use, especially combined SA + JA treatments, ameliorate root biomass and plant tolerance by restricting translocation Ni to the shoot, accumulating in roots, and also enhancing antioxidant defense systems.
