“…NPs Nanomaterials usually consist of particles smaller than 100 nm and their extreme small size implicates new physical, chemical and biological properties as they have higher surface area, solubility and surface reactivity than bulk counterpart materials. NPs interact with plants causing various changes in morphological and physiological traits of the plants, depending on the particles properties, plant species and the concentration at which the responses may differ from plant to other (Ruffini and Cremonini, 2009;Siddiqui et al, 2015). Nano-SiO 2 particles are one of NPs take a great concern by researchers in agricultural practices during the last few years.…”

An open field experiment was carried out during 2015 and 2016 seasons at the experimental nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University, Egypt. The purpose of present research was to investigate the effect of foliar application of nano silicon with different concentrations and gypsum soil application on growth, flowering and chemical constituents of Jatropha integerrima plants irrigated with different levels of saline water. The concentrations of saline water were (1000, 2000 and 4000 ppm), in addition to tap water (270 ppm) as a control, simultaneously plants were received monthly foliar application of nano silicon 1 and 2 mM or soil application of gypsum at 20 g/plant, either applied individually or in combination.The results showed that, elevating salt concentration in irrigation water decreased vegetative growth characteristics, flowering traits, leaves anatomy and chemical constituents. In contrast, increasing salinity of irrigation water boosted contents of proline, Ca%, Na%, Cl%, total phenolic and flavonoids. On the other hand, foliar application of nano silicon and soil addition of gypsum treatments either individually or in combination had favorable effects on enhancing vegetative parameters and chemical constitutes, meanwhile decreasing accumulation of Na%, ISSN 2166-0379 2017 http://jas.macrothink.org 137 Cl%, total phenolic and flavonoids in leaves. It can be concluded that, foliar spray of nano silicon combined with soil addition of gypsum was the best effective and economic treatment recommended for mitigating the harmful effect of salinity stress on Jatropha plants irrigated with saline water at concentration up to 4000 ppm.

“…The application of nanotechnology being mainly focused on animal science and medical research nanotechnology can also be applied to plant science research in order to analyze plant genomics and gene function as well as improvement of crop species (Monica and Cremonini 2009). The application of nanotechnology for remediation of contaminants may give promising results in the future.…”

“…It is established that these particles tagged to agrochemicals or to other substances could reduce injury to plant tissues and amount of chemicals released into the environment. Some contact is, however, inescapable, due to the strong interaction of plants with soil growth substrates (Monica and Cremonini 2009). In the field of nanotechnology, production of nanomaterials and products containing them are rapidly developing fields, which provides many opportunities for new innovation.…”

The issue of heavy metal pollution is very much concerned because of their toxicity for plant, animal and human beings and their lack of biodegradability. Excess concentrations of heavy metals have adverse effects on plant metabolic activities hence affect the food production, quantitatively and qualitatively. Heavy metal when reaches human tissues through various absorption pathways such as direct ingestion, dermal contact, diet through the soil-food chain, inhalation and oral intake may seriously affect their health. Therefore, several management practices are being applied to minimize metal toxicity by attenuating the availability of metal to the plants. Some of the traditional methods are either extremely costly or they are simply applied to isolate contaminated site. The biology-based technology like use of hypermetal accumulator plants occurring naturally or created by transgenic technology, in recent years draws great attention to remediate heavy metal contamination. Recently, applications of nanoparticle for metal remediation are also attracting great research interest due to their exceptional adsorption and mechanical properties and unique electrical property, highly chemical stability, and large specific surface area. Thus, the present review deals with different management approaches to reduce level of metal contamination in soil and finally to the food chain.

“…For many of these highly reactive ENPs, interactions with soil and organic matter surfaces may substantially mitigate their bioavailability. Similarly, most ENP toxicological studies on plants (reviewed by Monica and Cremonini, 2009;Navarro et al, 2008) have been conducted in hydroponic systems and thus are hard to relate to natural systems. Th us, fi eld experiments for some ENPs may substantially temper our concerns about their impacts and generate important new questions about the biogeochemical mechanisms that either reduce organismal exposure or reduce ENP toxicity.…”

An Ecological Perspective on Nanomaterial Impacts in the Environment

1954Growing concerns over the potential for unintended, adverse consequences of engineered nanoparticles (ENPs) in the environment have generated new research initiatives focused on understanding the ecological eff ects of ENPs. Almost nothing is currently known about the fate and transport of ENPs in environmental waters, soils, and sediments or about the biological impacts of ENPs in natural environments, and the bulk of modern nanotoxicogical research is focused on highly controlled laboratory studies with single species in simple media. In this paper, we provide an ecological perspective on the current state of knowledge regarding the likely environmental impacts of nanomaterials and propose a strategy for making rapid progress in new research in ecological nanoscience.
