“…A recent in vivo study reported the cytotoxicity of Se nanorods and spherical NPs in female mice. Their findings revealed an accumulation of NPs in the kidney, resulting in oxidative stress and tissue damage [154]. The toxicity of nanomaterials cannot be overlooked as it can potentially impact all organisms, and ultimately humans.…”

COVID-19 is a highly infectious respiratory disease that resulted in a global pandemic that has affected every stage and sector of life. Although it is mainly seen as a health issue, its impacts and ripple effects also resonated in the education, technology, agriculture, and research fields, creating socio-economic disruptions across the globe. In a bid to curb the wide spread of the disease, diverse sudden restriction measures were adopted, which had implications on food security and food availability via supply shortages and agricultural disruptions. Scientific studies such as those regarding nanotechnological developments, which had been underway for improving food quality and crop improvement, were also slowed down due to the complexities of the pandemic and global restrictions. Nanotechnology is a developing and promising field for further development of crop productivity by enhancing the proficiency of agricultural resources, thereby increasing food yield and food security. The application of nanotechnology crop farming involves the use of nano-scale materials that can be formulated into nano-emulsion, nano-capsule, nano-fertilizer, nano-pesticide, and nano-biosensor applications for improved agricultural productivity. In as much as the challenges of nanotoxicity could raise health and environmental concerns, advances in the biosynthesis of nanomaterials potentially allay such fears and concerns. Furthermore, these ideas will help in bridging the gap created by the pandemic on food availability, food security, and agriculture. This review focuses on the implications of the COVID-19 pandemic on nanotechnological applications for improved crop productivity and nanotechnological mitigation strategies on the impacts of the COVID-19 pandemic, risk assessment, and regulatory issues surrounding nano-crop farming, and this study provides an insight into future research directions for nanotechnological improvements in crop farming and the sustainable development of nano-enabled agriculture.

“…Heavy metals are considered metallic elements (in some cases they comprise metalloids, such as arsenic) whose compounds can induce toxicity at a low level of exposure, thus posing a critical threat to human health [ 1 , 2 , 3 , 4 , 5 ]. Although they are naturally occurring, human and wildlife exposure to heavy metals has increased due to excessive anthropogenic activities that contribute significantly to environmental contamination (e.g., industrial production, mining, and smelting) [ 6 ].…”

Prospects of Biogenic Xanthan and Gellan in Removal of Heavy Metals from Contaminated Waters

et al. 2022

Biosorption is considered an effective technique for the treatment of heavy-metal-bearing wastewaters. In recent years, various biogenic products, including native and functionalized biopolymers, have been successfully employed in technologies aiming for the environmentally sustainable immobilization and removal of heavy metals at contaminated sites, including two commercially available heteropolysaccharides—xanthan and gellan. As biodegradable and non-toxic fermentation products, xanthan and gellan have been successfully tested in various remediation techniques. Here, to highlight their prospects as green adsorbents for water decontamination, we have reviewed their biosynthesis machinery and chemical properties that are linked to their sorptive interactions, as well as their actual performance in the remediation of heavy metal contaminated waters. Their sorptive performance in native and modified forms is promising; thus, both xanthan and gellan are emerging as new green-based materials for the cost-effective and efficient remediation of heavy metal-contaminated waters.
