“…Furthermore, H. annuus is a typical agricultural plant used for oil production and animal feed. Its adaptability to a wide range of soil conditions has facilitated its widespread cultivation [ 22 ]. Based on our experimental setup, sunflower plants cultivated in soils with HMs adapted bacteria were able to accumulate about 1.7–2.5-folds more Cd and Zn in their shoots and roots, than plants grown in soils without this HMs resistant microbiota (Table 4 ).…”

Background Phytoremediation is a green technology that removes heavy metal (HM) contamination from the environment by using HM plant accumulators. Among soil microbiota, plant growth promoting bacteria (PGPR) have a role influencing the metal availability and uptake. Methods This current study evaluates the plant growth promoting qualities of microbial flora isolated from rhizosphere, plant roots, and marine aquatic HMs polluted environments in Alexandria through several biochemical and molecular traits. Metal contents in both collected soils and plant tissues were measured. Transcript levels of marker genes (HMA3 and HMA4) were analyzed. Results Three terrestrial and one aquatic site were included in this study based on the ICP-MS identification of four HMs (Zn, Cd, Cu, and Ni) or earlier reports of HMs contamination. Using the VITEK2 bacterial identification system, twenty-two bacteria isolated from these loci were biochemically described. Pseudomonas and Bacillus were the most dominant species. Furthermore, the soil microbiota collected from the most contaminated HMs site with these two were able to enhance the Helianthus annuus L. hyper-accumulation capacity significantly. Specifically, sunflower plants cultivated in soils with HMs adapted bacteria were able to accumulate about 1.7–2.5-folds more Zn and Cd in their shoots, respectively. Conclusion The influence of PGPR to stimulate crop growth under stress is considered an effective strategy. Overall, our findings showed that plants cultivated in HMs contaminated sites in the presence of PGPR were able to accumulate significant amounts of HMs in several plant parts than those cultivated in soils lacking microbiota.

“…Herbaceous plants of natural biocenoses have a greater potential to accumulate toxic elements compared to agrocenoses (Murashova et al, 2020). It is important to point out that the literature clearly shows that sunfl ower can accumulate toxic elements (As, Pb, Cu, Cd, Ni, Cr, Co), mainly in shoots and roots (Dhiman et al, 2017;Stoikou et al, 2017;Angelova et al, 2016;Garcia et al, 2006). Since growing sunfl ower plants has a high potential to collect metal contaminants, they are considered "hyperaccumulators" of metals (Dhiman et al, 2017).…”

Toxic element pollution is an ecological concern in the regions where mining, industry and agriculture are developing. Anthropogenic impact on the environment results in the reduction of the population of honey bees over the world with varying degrees of morbidity and mortality. Bees exposed to contaminants produce polluted products through various sources, including foraging activities on contaminated plants. Therefore, monitoring of honey bee products in terms of toxic elements is very important for food safety and for preventing potential future ecological problems. The data presented in this review are useful for bee health protection and improving the quality and safety of honey production chain.

“…Packed with essential polyunsaturated fatty acids (linoleic acid, oleic acid), sunflower seeds are also a good source of proteins and amino acids that are essential for growth. Because sunflower plants are to some extent able to extract toxic elements from soil, they have been planted in contaminated soils to clean the soil from toxic elements [6]. However, exposure of sunflowers to AgNPs/Ag + is known to cause oxidative stress and create reactive oxygen species (ROS), and as a result the activity levels of antioxidant defence enzymes and lipid peroxidation (LPO) increase.…”

When soil is contaminated with silver (Ag), plants take up Ag and is concentrated in roots and leaves, with its effects reflected in crop health and yield. This study investigated the toxicity of silver nanoparticles (AgNPs) and silver nitrate (AgNO 3 as Ag +) to sunflower seeds grown in soils amended with 150 mg/kg of Ag either as AgNPs or AgNO 3. Exposure of the sunflower seeds to soils amended with Ag increased plant lipid peroxidation, activities of antioxidants enzymes (catalase, superoxide dismutase, glutathione-S-transferase), peroxidases (glutathione peroxidase pyrogallol peroxidase, guaiacol peroxidase), oxidases (ascorbate oxidase), urease, total phenolic compounds, vitamins (retinols, alpha-tocopherol and L-ascorbic acid) but inhibited chlorophyll, total carotenoids, total soluble carbohydrates, phenolic compounds and total soluble proteins. In general, AgNO 3 increased the above-mentioned parameters in sunflower more than did AgNPs, except for the tested vitamins, which were more affected by AgNPs. The results showed that Ag accumulation in the root > leaf > stem and human food security risk is enhanced in sunflower seeds exposed to Ag compounds.
