“…Furthermore, the application of organic amendments may result in restricted translocation of soluble Cd from root to shoot of the tested plants. The rather high OM content and soil pH increase Cd retention capacity, and thus decrease Cd solubility and bioavailability in soils 23 , 27 , as seen the remarkably low values in the treatments amended with organic amendments, particularly Cd-Pig and Cd-Leo treatments.…”

“…Previous research has indicated that compost-amended soils decreased Cd bioavailability by approximately 50% in the hyperaccumulator P . hortorum , whereas compost addition reduced lead (Pb) accumulation in shoots and roots by 33% and 28%, respectively 23 , 27 . Furthermore, the application of organic amendments may result in restricted translocation of soluble Cd from root to shoot of the tested plants.…”

The marigolds (Tagetes spp.) in this study were classified as excluders for cadmium (Cd); however, their leaves also accumulated substantial Cd content. Among the experimental treatments (i.e., control, cattle manure, pig manure, and leonardite which served as soil amendments), pig manure resulted in significantly increased growth performance for all marigold cultivars as seen by relative growth rates (119–132.3%) and showed positive effects on leaf anatomy modifications, e.g., thickness of spongy and palisade mesophyll, size of vein area and diameter of xylem cells. This may be due to substantially higher essential nutrient content, e.g., total nitrogen (N) and extractable phosphorus (P), in pig manure that aided all marigold cultivars, particularly the French cultivar which exhibited the highest relative growth rate (132.3%). In the Cd-only treatment, cell disorganization was observed in vascular bundles as well as in palisade and spongy mesophyll, which may have been responsible for the lowest plant growth performance recorded in this study, particularly among the American and Honey cultivars (RGR = 73% and 77.3%, respectively).

“…Unlike other organic pollutants, Cd enters the environment via a complex set of pathways such as metal ores mining and smelting, Cd containing fertilizers application, fossil fuel combustion, and industrial exhaust emissions, causing Cd accumulation in nature 2 . The accumulation of Cd in the environment not only pollutes plants and water flow, 3 but also has toxic effects on the heart, liver, kidney, and other organs of the body, thereby damaging their function and structure 4 . Cd‐induced toxicity is mediated through the production of free radicals and subsequent accumulation of reactive oxygen species (ROS), which induce biochemical alterations, such as lipid peroxidation, protein denaturation, and DNA hydroxylation 5 .…”

Cadmium (Cd) is an environmental pollutant that has an enormous influence on agricultural production, but selenium (Se) can alleviate its toxicity. The present study aimed to illustrate the effects of Se on Cd-induced heart injury. All 40 rabbits were randomly divided into four groups: control group, Se [0.5 mg kg À1 Ábody weight (BW)] group, Cd (1 mg kg À1 ÁBW) group, and Se + Cd group. After 30 days of feeding, morphological changes, the levels of oxidative stress and myocardial enzyme, the content of cardiac troponin T, programmed cell death (pyroptosis, autophagy and apoptosis), and PI3K/AKT/PTEN transduction capacity were observed. The results showed that Cd destroyed the physiological balance of trace elements and caused myocardial damage, increased the cardiac oxidative damage and led to programmed cell death.Coadministration of Se prominently ameliorated histological lesions and improved cardiac function of hearts in Cd-induced rabbits. Furthermore, Se exerted detoxification and oxidation resistance, maintained trace element homeostasis, and alleviated the changes of mRNA and protein levels of pyroptosis-, autophagy-and apoptosiscontrolling factors and PI3K/AKT/PTEN signal molecules caused by Cd. In conclusion, Se might protect against Cd-induced pyroptosis, autophagy and apoptosis by interfering with PI3K/AKT/PTEN signaling in heart.

“…When in soils, PTE's can show different behaviors depending on soil properties and element characteristics (Antoniadis et al 2008;Shaheen et al 2017;Zhao et al 2020). Sorption process in soils are of high relevance because they avoid movement of toxic elements through soil pro le and consequent contamination of subsurface water (Gul et al 2019). Among the PTE's in steel mill wastes, Cd, Ni, Pb, Zn, Mn and Cu stand out due to the many harmful effects they can pose in in living beings, when present in high concentrations (Yu et al 2017).…”

Potentially toxic elements (PTE’s) are of great concern in steel mill wastes. Therefore, in other to use them as potential fertilizers in soil, risk assessments are needed. Three steel mill wastes were tested as possible amendments for soils at six different doses (0; 0,5; 1; 2; 4; 8; 16 t ha-1): Phosphate mud (PM), Metallurgical press residue (MPR) and Filter press mud (FPM) during rice cultivation in a pot experiment in a Haplic Gleisol. Analysis on rice tissues, including roots, shoots, husk and grains were conducted and contents of Cu, Cd, Ni, Zn, Mn and Pb were assessed. Translocation and bioaccumulation factors were calculated for each element. In general, PTE’s are more accumulated in roots and greater contents of Zn and Mn were found, while the lowest ones were found for Pb, probably due to its lack of functional roles during plants development. Higher translocation was observed for Mn, which is associated to the redox conditions of rice cultivation and the high mobility of this element under this condition. Application of steel mill wastes can increase PTE’s bioavailability and translocation factors, especially PM, but all of the wastes reveal a high hazard index.
