“…This reflects the recent increasing efforts in using this branch of nanotechnology in different environmental sectors (Patil et al 2016;Auty 2017;Iavicoli et al 2017). Due to the intensive urbanization and human activities, pollution has become one of the most important environmental challenges.…”

“…This remediation for different environments using nanoparticles/nanomaterials is called nanoremediation (Kuppusamy et al 2016;El-Ramady et al 2017). This nanoremediation could be performed in the presence of nanoparticles/ nanomaterials using plants or phyto-nanoremediation (Shalaby et al 2016;Martínez-Fernández et al 2017), microbes or microbial nanoremediation (Patil et al 2016;Davis et al 2017) or animal or zoonanoremediation (Belal and El-Ramady 2016;El-Ramady et al 2017). Therefore, there is an urgent need for the environmental pollution control under a sustainable management (Pandey et al 2016;El-Ramady et al 2017;Prashanthi et al 2017).…”

“…Several applications of nanomaterials/nanoparticles have been used in many sectors including sustainable crop production, reduction of nutrient losses, suppression disease and enhancement of crop yield (Shalaby et al 2016;Davari et al 2017;Kaphle et al 2017). The nanoremediation for sustainable crop production in polluted lands should be managed in a proper way before the expansion in such polluted lands for the agricultural production (Patil et al 2016;El-Ramady et al 2017). This currently resulted from the difficulty in measuring the sustainability of crop production in such polluted lands as well as lack in evaluating techniques for the performance of phytoremediation in frame of bioeconomy (Shalaby et al 2016;Mishra et al 2017;Shivlata and Satyanarayana 2017;Verma et al 2017).…”

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...

“…RO is by far the most effective method in removing dissolved silica from brackish water. The present study investigates the toxicity of NDMA as a known water contaminate and silica NPs as newly NPs used in membranes separationand found in high concentrations in brackish water [20]. NDMA and silica NPs exposed to human skin keratinocytes (HaCaT) and human colon carcinoma (caco-2), the toxicity determined using3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), and Lactate dehydrogenase (LDH) assays also the particle morphology was identified by Scanning Electron Microscope (SEM).…”

Nanoparticles (NPs) offer the possibility of safe removal of pollutants and microbes in water treatment and purification. Nowadays, NPs are used in the detection and purification of water from chemicals and biological substance such as metals (cadmium, copper, lead and zinc) nutrients (nitrate, nitrite ammonia and phosphate) bacteria, viruses, parasite and antibiotics. Metal containing NPs are among the four classes of particles used commonly in water treatment. Membrane technologies such as Ultrafiltration (UF), Nanofiltration (NF) and Reverse Osmosis (RO) have been widely used all over the world especially for water treatment and desalination. NPs after have been incorporated into membranes gained attention due to its ability to enhance membrane permeability, mechanical properties and selectivity in some cases. However, these membranes are suspected to fouling causing NPs and other contaminate to reach waterways. In this study, we tested the toxicity of SiO 2 NPs synthesised by Stöber method and N-Nitrosodimethylamine (NDMA) as potent known carcinogens forms during chlorination on HaCaT and caco-2 cell lines for 4, 24 and 48h using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays also the morphology and size of SiO 2 determined by Scanning electron microscopy (SEM). After exposure to SiO 2 NPs (concentrations between 0.05-2 mg/mL), the concentration of 2 mg/mL inactivated LDH in both cell lines; however, it did not reduce the metabolic activity of both cell lines when MTT assay used. SEM revealed spherical and uniformed SiO 2 particles with size 200 nm in diameter. NDMA (concentrations between 0.1-1000 µg/mL) inactivated LDH leakage in HaCaT and caco-2 also reduced the metabolic activity of HaCaT cell line at 48 hours exposure. The outcome of this study suggest that a concentration of SiO 2 <2 mg/mL used in water treatment can reduce the risk of nanmaterials toxicity to human and possibly the ecosystem. Our results urgefor more studies on the effect of nanomaterials to the aquatic environment and human exposure to NPs.
