“…Recently, NMOs, particularly Febased, have been used in the removal of pollutants from natural waters and wastewater, as highlighted in reviews by Hua et al (2012) and Xu et al (2012). Several studies have also demonstrated the scavenging capabilities of Fe-and Mn-NMOs for both metals and, to a lesser extent, organic molecules in soils and sediments (Waychunas et al 2005;Vítková et al 2018;Vítková et al 2017;Jiang et al 2018;Varanasi et al 2007;Gil-Díaz et al 2016;Michálková et al 2014;Babakhani et al 2018). The overall upshot of these studies is that Fe-and Mn-NMOs participate in a wide variety of oxidation-reduction, sorption and aggregation reactions that can limit the mobility of toxic metal(loid)s and organic molecules within soils under a range of environmental conditions.…”

Environmental contextNanominerals are more reactive than bulk minerals, a property that strongly influences the fate of nutrients and contaminants in soils and plants. This review discusses applications of Fe- and Mn-nano-oxides in agricultural systems and their potential to be used as fertiliser and contaminant adsorbents, while addressing potential phytotoxicity. We discuss areas where significant advances are needed, and provide a framework for future work. AbstractRising population growth and increase global food demand have made meeting the demands of food production and security a major challenge worldwide. Nanotechnology is starting to become a viable remediation strategy of interest in farming. Ultimately, it may be used as a sustainability tool in agricultural systems. In these roles, it could be used to increase the efficiency of techniques such as food monitoring, pathogen control, water treatment and targeted delivery of agrochemicals. In addition to these uses, nanoparticles, particularly nano-metal-oxides (NMOs), have been engineered to act as contaminant scavengers and could be applied to a wide range of systems. Numerous studies have investigated the scavenging ability of NMOs, but few have investigated them in this role in the context of agricultural and food systems. Within these systems, however, research has demonstrated the potential of NMOs to increase crop health and yield but few have studied using NMOs as sources of key micronutrients, such as Fe and Mn. In this review, we address previous research that has used Fe- and Mn-NMOs in agricultural systems, particularly the worldwide crop production of the four major staple foods – rice, wheat, maize and soybeans – highlighting their application as fertilisers and sorbents. Fe- and Mn-NMOs are strong candidates for immobilisation of agricultural contaminants in soils and, because they are naturally ubiquitous, they have the potential to be a cost-effective and sustainable technology compared with other remediation strategies.

“…With that being said, one major challenge that humans face these days is the restoration of contaminated soil, water and air to reach a quality level in which Journal of Biomaterials and Nanobiotechnology they no longer represent an environmental and health harm [51] [52]. Nevertheless, traditional remediation techniques are not so effective, quite costly, laborious and may also produce its own contamination [50] [51] [52]. As a promising alternative, nanoremediation has been investigated and might be a less costly and more effective solution to conventional remediation, as it relies on certain nanomaterials, like nanoparticles, which have the capacity to react with the pollutant, enable the transformation into less toxic compounds or immobilize it by adsorption [52].…”

Also, the use of nanomaterials provides more technologies for in situ remediation, which is less expensive, and avoids the necessity to excavate into the ground, the disposal of contaminated soil or "pump and treat" for groundwater [28] [50].…”

The agricultural sector has many problems achieving the desired yield in products because of pathogens, viruses, pesticides, herbicides, temperature, soil moisture, among others. Nanotechnology, along with other sciences, has emerged in industry and society due to the interest in solving problems such as those mentioned above, in order to serve the needs of the world population. The present review discusses the principal topics about Nanobiotechnology, such as generalities, applications, aspects that can be improved and perspectives, beside its influence in the agriculture industry.

“…Thus, using of these nanoparticles in cleaning the environment from pollutants is called nanoremediation. Many studies have been published concerning the benefits of nanoremediation or nanotechnology for environmental clean-up including heavy metals removing from soils (Ingle et al 2014;Araújo et al 2105;Jain et al 2015;Fajardo et al 2015;Jain et al 2016;Gillies et al 2016;Gil-Díaz et al 2016a;Martínez-Fernández et al 2017), using plants in clean up (Ghormade et al 2011;Capaldi Arruda et al 2015;Gil-Díaz et al 2016b;Martínez-Fernández et al 2017), remediation of waste water (Hamza et al 2016;Peeters et al 2016;De Luca and Ferrer 2017;Shekarriz et al 2017;Xue et al 2017) degradation of pesticides in soil and water (El-Temsah and Joner 2013;Gomes et al 2014;El-Temsah et al 2016;Kaushik and Djiwanti 2017). Nanoremediation of soils, as a promising strategy in minimizing the entry of pollutants in plant parts, can be performed using nanoparticles such as zero-valent iron nanoparticles (nZVI), ZnO, TiO 2 , carbon nanotubes, fullerenes and bimetallic nano-metals.…”

MANY global problems threaten our life on the Planet including climate changes, environmental pollution, food and soil security, energy crisis, etc. This environmental pollution has not only mainly serious risks and stress involving the human health and safety of the entire ecosystem but also the quantity and quality of crops productivity worldwide. Due to the great gap between the global food production and the global consumption, there is a crucial need to cultivate these contaminated lands sooner or later. Therefore, the removing of pollutants from soils and waters should be performed in frame of sustainable remediation and sustainable energy production accordingly. Depending on many factors (source and kind of pollutants, land use and the economics of water and soil resources, etc) many strategies should be addressed for the sustainable and integrated management of polluted lands. Nanoremediation is a promising strategy in controlling pollution and management. Three major applications of nanoremediation could be characterized including detection of pollution using nanosensors, prevention of pollution, purification and remediation of contamination. Further studies also concerning the impact of changing climate on the nanoremediation process in the agroecosystems should be considered. Thus, this review will focus on the evaluation of environmental nanoremediation and its strategy in polluted lands under climate changes. Using of nanotechnology in pollution control as well as the environmental pollution and its sustainable management also will be highlighted.Keywords: Environmental nanoremediation, Climate change, Pollution, Crop production, Environmental stress. IntroductionClimate changes are a great challenge facing the human kind as well as other living things. The production of crops and other agricultural features are extremely susceptible to changes in climate. So, these global changes will be caused major shifts in crop distribution due to climate changes in the future. Moreover, it has been estimated that climate changes are likely to reduce yields and/or damage crops in the 21 Removing of pollutants from soils and waters could be linked with both the sustainable remediation as well as sustainable energy production (Kovacs and Szemmelveisz 2017; Zheng and Shi 2017). Many strategies for the sustainable and integrated management of polluted lands should be addressed depending on several factors e.g., type of pollutants and their level, the purpose of land use after remediation, soil characterization and its topography, climate , cropping patterns and the availability of resources and their economics (El-Ramady et al. 2017;Saha et al. 2017a). Furthermore, a great debate concerning using of lands for crop food production (under growing global population) or energy crop production was and still for ages (Paschalidou et al. 2016). Therefore, a global and holistic strategy in facing the main three threats including hunger, lack of energy and pollution of environment as well as climate changes should be esta...
