“…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...

“…Based on their purpose, agrochemicals can be classified into insecticides, herbicides, bactericides, fungicides, miticides, molluscicides, nematicides, wood preservatives, and rodenticides. Depending on the chemical structure of the agrochemicals, they can be classified into organochlorines, organophosphates, carbamates, chlorophenols, and synthetic pyrethroids [1]. According to the World Health Organization (WHO), agrochemicals can be classified according to their toxicity depending on the median lethal dose (LD 50 ) for rats (Table 1) [2].…”

Natural Organic Compounds for Application in Organic Farming

Chemical fertilizers, pesticides, and fungicides are widely used in agriculture to improve crop yields. Most of the compounds used are synthetic, and their overuse causes environmental pollution and human health problems. Currently, several countries are working to reduce the use of agrochemicals. Organic agriculture is now emerging as a sustainable alternative to traditional agriculture using environmentally friendly strategies such as the application of organic fertilizers from plant and animal waste and pesticides based on plant extracts and microbials. However, the availability of commercial biopesticides and organic fertilizers is very limited because there are certain barriers to the commercialization of biological products. These barriers include small available quantities of raw materials and strict registration laws requiring toxicological tests and other studies that are expensive and time consuming. The objective of this review is to provide details about the various organic fertilizers and pesticides that do not have the same disadvantages as synthetic compounds in terms of persistence and toxicity.

“…Although pharmaceuticals have been present in water for decades, their levels in the environment have only recently begun to be quantified and acknowledged as potentially hazardous to ecosystems . However, emerging substances have recently been detected in water resources worldwide, raising human and environmental health concerns . Several studies in Europe and the United States have indicated that many of these compounds are present in the effluents of wastewater treatment plants, surface water, and groundwater .…”

“…The efficiency of these technologies can depend on the characteristics of the pharmaceuticals. According to Hamza et al ., there are different pharmaceutical sub‐groups depending on usage: (i) antibiotics (e.g. amoxicillin, chloramphenicol, ciprofloxacin, norfloxacin, and erythromycin); (ii) antidepressant (e.g.…”

BACKGROUND: This study analyzed the effects of carbamazepine, ciprofloxacin and ibuprofen on the behavior of a membrane bioreactor (MBR) system treating urban wastewater that was doped continuously with three different concentrations of this mix of pharmaceuticals under a hydraulic retention time of 6 h. RESULTS: The degradation capacity of these chemicals and the heterotrophic kinetics regarding the organic matter removal were evaluated in the control and doping cycles.CONCLUSIONS: Although the MLSS decreased drastically, these differences were not observed in the organic matter removal as the increase of cell growth rate cancelled out the increase in cell decay rate due to the chemical stress caused by the addition of pharmaceuticals, as shown by the increased organic matter degradation rate from 86.27 mgO 2 L −1 h −1 in the control cycle to values within the limits 183.97 mgO 2 L −1 h −1 and 192.88 mgO 2 L −1 h −1 in doping cycles. The degradation rates were 0.0154, 0.0152 and 0.0160 gS/(( gS in /L)*h*mgMLSS) for carbamazepine, ciprofloxacin and ibuprofen, respectively, involving removal yields higher than 71.9, 88.7 and 94.7% for carbamazepine, ciprofloxacin and ibuprofen, respectively, at the three different concentrations tested. Therefore, MBR technology can be used as a reliable process to significantly reduce this mix of pharmaceuticals without reducing its organic matter removal capacity.
