“…This indicates the zinc concentration had caused root toxicity symptoms. This result concurred with that reported by [12], which had a similar observation on the sunflower under zinc stress conditions in the soil. The inhibition of the stem length under the influence of zinc concentration is illustrated in Figure 2(b).…”

It has been noted that zinc contamination is hazardous which induces researchers seek new means to overcome it. One of the methods is to employ sunflower plant to eliminate zinc in soil. However, there is insufficient information about zinc phytoremediation by sunflower Helianthus annuus in hydroponic system. Hence in this study, a 15-day experiment was conducted using zinc concentrations of 0, 10, 20, and 30 mg/L in a hydroponic system. The effects of zinc concentration on the plant growth (length of root, length of stem and number of leaf), zinc uptake and zinc translocation were evaluated. The findings showed that the plant growth was inhibited, where the zinc concentrations had affected the growth of the sunflower root, length and stem, and the zinc uptake significantly (p<0.05). It was also found that there was a significant variation of root length and zinc uptake in leaves within certain phases statistically (p<0.05). Then the translocation factor was found significant different for the time parameter but not the zinc concentrations (p<0.05). Therefore, this experiment concluded that the sunflower plant was highly tolerant to zinc and able to extract the zinc from contaminated environments. Lastly, this study showed that the sunflower is potential to phytoremediate zinc in a hydroponic system.

“…Continuous or natural phytoextraction and chemically induced phytoextraction are two ways to phytoextraction [103]. First, a network of roots extracts continuous phytonutrients, which are subsequently directed to upper plant tissues, which inflight the soil to remove toxic metals [104] (Jadia and Fulekar, 2008). The harvested plant biomass, which is the result of continuous phyto-extraction, can produce biogas and be burned.…”

Contamination of aquatic ecosystems by various sources has become a major worry all over the world. Pollutants can enter the human body through the food chain from aquatic and soil habitats. These pollutants can cause various chronic diseases in humans and mortality if they collect in the body over an extended period. Although the phytoremediation technique cannot completely remove harmful materials, it is an environmentally benign, cost-effective, and natural process that has no negative effects on the environment. The main types of phytoremediation, their mechanisms, and strategies to raise the remediation rate and the use of genetically altered plants, phytoremediation plant prospects, economics, and usable plants are reviewed in this review. Several factors influence the phytoremediation process, including types of contaminants, pollutant characteristics, and plant species selection, climate considerations, flooding and aging, the effect of salt, soil parameters, and redox potential. Phytoremediation’s environmental and economic efficiency, use, and relevance are depicted in our work. Multiple recent breakthroughs in phytoremediation technologies are also mentioned in this review.

“…In plants, these metals directly or indirectly cause a wide range of physiological and biochemical dysfunctions that lead to reduced yield (Amari et al, 2017). Cd, Pb, and Ni show phytotoxic effects on germination and germ development in Lactuca sativa, Brassica oleraceae, Lycopersicon esculeatum, Raphanus sativus (Johnson et al, 2011), Helianthus annus (Jadia & Fulekar, 2008).…”

The aim of this study was to determine the effect of lead, nickel and cadmium on the germination of barley seeds (Hordeum vulgare L.) of Jadran variety. Based on the percentage of germination, germination energy, and root and hypocotyl length, authors done an analysis of the effects of PbCl2, NiCl2, CdCl2 solutions, in concentrations of 103 mol/m3, 102 mol/m3, 10 mol/m3, 1 mol/m3, 10-1 mol/m3, 10-2 mol/m3. The results showed that germination and germgrowthin stress conditions which are caused by heavy metals depend on the type of metal and its concentrations. The most toxic effect of alltested solutions had CdCl2, and the weakest toxic effect had PbCl2.
