“…This was supported by the strong correlation between the contents of Pb in the plant shoots and the contents of total Pb (r = 0.80, p < 0.001) and extractable Pb (r = 0.81, p < 0.001). This result also implies the strong effect of the bioavailability of Pb in the soil on the uptake and accumulation of Pb in plant shoots, consistent with previous studies [65,82]. Our results also showed higher contents of Pb in the shoots of I. aquatica (586 mg/kg-DW) than those reported (179 and 232 mg/kg) when the plants were growing in soil containing 864 and 3352 mg Pb/kg, respectively [32], possibly because of the differences in the Pb contents in the soil.…”

“…The ratio of the content of extractable Pb to that of total Pb in the present study was lower than that reported by Rodríguez-Seijo et al [63] and Ngoc et al [64], but higher than that reported by Zhang et al [65] and Lenart and Wolny-Koładka [66]. The differences in the proportions of extractable Pb in different studies may be attributable to the total Pb contents in the soils and the different properties of the soils (e.g., soil pH, soil texture, organic carbon content, cation exchange capacity, calcium carbonate equivalents, and nutrient balance) [11,[63][64][65][66][67][68]. Extractants also play an important role in the amounts of extractable metals detected [63,64,69].…”

This study was conducted to determine the soil contamination and the accumulation of arsenic (As) and heavy metals including chromium (Cr), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) in 15 native and cultivated plant species in a Pb recycling area of Dong Mai village, Hung Yen Province, Vietnam. The analysis of 32 soil samples collected from seven different sites in the study area revealed that the contents of Al, Fe, As, Cr, Cu, Zn, Cd, and Pb in the soils ranged from 6200–32,600, 11,300–55,500, 5.4–26.8, 24.9–290, 66.0–252, 143–455, 0.71–1.67, and 370–47,400 mg/kg, respectively. The contents of As, Cr, Cu, Zn, Cd, and Pb in rice grains and the shoots of 15 plant species ranged from 0.14–10.2, 1.00–10.2, 5.19–23.8, 34.7–165, 0.06–0.99, and 2.83–1160 mg/kg-dry weight (DW), respectively. Hymenachne acutigluma (Steud.) Gilliland, a potential hyperaccumulator of Pb (1160 mg/kg–DW), is considered the best candidate for phytoremediation of Pb-contaminated soil. The cultivation of rice and vegetables, and the use of some native plants for food for humans, pigs, and cattle should be managed with consideration of the accumulation of Pb in their aboveground biomass.

“…The untreated seep soils had soil solution Pb concentrations (all <6 µg/L) that were below or marginally above the estimated typical background levels. One study (Zhang et al 2019) showed that even in a very sensitive soil from Germany the concentration causing just a 10% reduction in the reproduction (i.e., the reproduction EC10) of the Enchytraeus crypticus worm was 6 µg/L, whereas the EC10 values in the other soils tested ranged from 21 to 90 µg/L. This would suggest that the Pb soil solution concentrations in the seep soils would not pose any substantial risk to invertebrates.…”

During clarification processes of raw water, a vast amount of by‐product known as “drinking water‐treatment residuals” (WTRs) are produced, being principally composed of hydroxides of the Al or Fe salts added during water treatment plus the impurities they remove. Aluminum‐based (Al‐WTR) and iron‐based (Fe‐WTR) materials were applied at 10% w/w to degraded, bare (unvegetated) soils from a restored coal mining site in central England (pH <3.9) to study their potential amelioration effects on earthworm mortality, biomass yield of seedling plants, and element concentrations in plant tissues, earthworm tissues, and soil solutions. A separate treatment with agricultural lime was also conducted for comparison to evaluate whether any observed improvements were attributable to the liming capacity of the WTRs. After completion of the trials, all samples were subjected to a wet–dry cycle, and the experiments were repeated (i.e., simulating longer‐term effects in the field). Both types of WTRs significantly increased the biomass of plants, and in some treatments, survival of earthworms was also enhanced compared to nonamended soils. Excess plant tissue element concentrations and element concentrations in soil solutions were reduced in amended soils. The implications are that adding WTRs to mining‐impacted soils is a potentially viable, sustainable, and low‐cost remediation method that could be used globally to improve the soil condition.

“…Meanwhile, higher significant BCF Pb of stem resulted from 450 and 850 mg Pb acetate/kg soil, without a significant difference between such treatments. Soil properties such as pH, CEC, and Ca concentration have a significant (p ≤ 0.05) effect on the bioavailability of Pb in soil (Zhang et al 2019). BCF and TF are key values that evaluate a plant's potential for phytoextraction or phytoestabilization (Rafati et al 2011).…”

The contamination of agricultural soil with heavy metals is a complex phenomenon that causes negative consequences for various organisms. Poplars may have considerable phytoremediation potential, and this plant species can tolerate Cd, Cu, and Pb up to 15.6, 63.6, and 173.3 mg kg-1 soil, respectively, with 100% survival. The analyzed data revealed significant reduction in vegetative growth traits and leaf N, P, K, and carbohydrate (%) and leaf green color degree. However, a simultaneously significant increase in enzymatic activities and electrolyte leakage were recorded in comparison to control plants. A bioconcentration factor of plant organs was ˂ 1, and the translocation factors (TF) of Cd and Cu were ˂ 1 ( ˂100%) under various concentrations of each heavy metal, while TF of Pb was ˃ 1(>100%), except for the first level. More Cd, Cu, and Pb contents were localized in roots compared to leaves or stems. Thus, the risk of contamination through leaf can be minimized. Populus nigra has defense mechanisms against Cd, Cu, and Pb up to 7.8, 29.8, and 91.1 mg/kg soil, respectively because the tolerance index (TI) of either biomass or root was >0.8. Finally, it is a good candidate for research of phytoremediation and phytoextraction.
