“…Cd inhibits germination and reduces the growth of germinating seedlings [40,41]. The suppression of seed germination mainly occurs due to inhibiting metabolic and physiological processes [42,43]. Cd toxicity in seeds reduces water absorption capacity and starch digestion and impairs the growth of growing embryos [44].…”

Soil contamination with cadmium (Cd) is a severe concern for the developing world due to its non-biodegradability and significant potential to damage the ecosystem and associated services. Industries such as mining, manufacturing, building, etc., rapidly produce a substantial amount of Cd, posing environmental risks. Cd toxicity in crop plants decreases nutrient and water uptake and translocation, increases oxidative damage, interferes with plant metabolism and inhibits plant morphology and physiology. However, various conventional physicochemical approaches are available to remove Cd from the soil, including chemical reduction, immobilization, stabilization and electro-remediation. Nevertheless, these processes are costly and unfriendly to the environment because they require much energy, skilled labor and hazardous chemicals. In contrasting, contaminated soils can be restored by using bioremediation techniques, which use plants alone and in association with different beneficial microbes as cutting-edge approaches. This review covers the bioremediation of soils contaminated with Cd in various new ways. The bioremediation capability of bacteria and fungi alone and in combination with plants are studied and analyzed. Microbes, including bacteria, fungi and algae, are reported to have a high tolerance for metals, having a 98% bioremediation capability. The internal structure of microorganisms, their cell surface characteristics and the surrounding environmental circumstances are all discussed concerning how microbes detoxify metals. Moreover, issues affecting the effectiveness of bioremediation are explored, along with potential difficulties, solutions and prospects.

The impact of heavy metal presence in soil on cereal crops is a growing concern, posing significant challenges to global food security and environmental sustainability. Cereal crops, vital sources of nutrition, face the risk of contamination with toxic heavy metals released into the environment through human activities. This paper explores key aspects requiring thorough investigation to foster innovation and understand intricate interactions between heavy metals and cereals. Visible symptoms and physiological changes resulting from heavy metal contamination, such as chlorosis and stunted growth, demand further research to devise targeted mitigation strategies and sustainable agricultural practices. Root barrier formation, mycorrhizal symbiosis, and metal-binding proteins emerge as critical defence mechanisms for combating heavy metal stress, offering opportunities for developing metal-tolerant cereal varieties. Research on metal bioavailability and food safety implications in cereal grains is vital to safeguard human health. This paper reveals that multidisciplinary collaboration and cutting-edge technologies are essential for promoting innovation beyond the state of the art in elucidating and mitigating the impacts of heavy metals on cereal crops. Genetic and breeding approaches show promise in developing metal-tolerant cereal varieties, while agronomic practices and soil amendments can reduce metal bioavailability and toxicity. Unravelling the complex mechanisms underlying heavy metal uptake and tolerance is essential for sustainable cereal agriculture and worldwide food sustainability. Embracing the challenges of heavy metal pollution through proactive research and collaboration can secure a resilient future for cereal crops amid evolving environmental conditions.

“…However, excessive metal uptake by plants can have significant consequences both for the plant itself and for human health when these plants are consumed. In this detailed overview, we will explore the conse-quences of metal uptake in plants and its potential effects on humans [46,85,104,105]. [112,114], and individuals with compromised immune systems or underlying health conditions are particularly vulnerable to the adverse effects of metal exposure [116].…”

The increasing public concern over the negative impacts of chemical fertilizers and pesticides on food security and sustainability has led to exploring innovative methods that offer both environmental and agricultural benefits. One such innovative approach is using plant-growth-promoting bioinoculants that involve bacteria, fungi, and algae. These living microorganisms are applied to soil, seeds, or plant surfaces and can enhance plant development by increasing nutrient availability and defense against plant pathogens. However, the application of biofertilizers in the field faced many challenges and required conjunction with innovative delivering approaches. Nanotechnology has gained significant attention in recent years due to its numerous applications in various fields, such as medicine, drug development, catalysis, energy, and materials. Nanoparticles with small sizes and large surface areas (1-100 nm) have numerous potential functions. In sustainable agriculture, the development of nanochemicals has shown promise as agents for plant growth, fertilizers, and pesticides. The use of nanomaterials is being considered as a solution to control plant pests, including insects, fungi, and weeds. In the food industry, nanoparticles are used as antimicrobial agents in food packaging, with silver nanomaterials being particularly interesting. However, many nanoparticles (Ag, Fe, Cu, Si, Al, Zn, ZnO, TiO2, CeO2, Al2O3, and carbon nanotubes) have been reported to negatively affect plant growth. This review focuses on the effects of nanoparticles on beneficial plant bacteria and their ability to promote plant growth. Implementing novel sustainable strategies in agriculture, biofertilizers, and nanoparticles could be a promising solution to achieve sustainable food production while reducing the negative environmental impacts.
