“…Amphiphilic polyurethane removes multinuclear aromatic hydrocarbon from the soils and polyamidoamine dendrimers remove heavy metals from waste waters (Bhardwaj et al, 2019;Arkas et al, 2019). Removal of metal ions, dyes and microorganisms from water by polymer nanocomposites had also been reported by Mittal et al (2015) and Khare et al (2016).…”

Nanotechnology can play important role in the field of environmental restoration and science. Environmental pollution has become one of the major problems of developing as well as developed countries at present time. Unchecked exploitation of resources, rapid industrialization, urbanization as well as excessive agricultural activities to meet the demands of the ever increasing population are the major cause for contamination of the land, water and atmosphere at all levels. Increasing pollution is not only resulting in the destruction of biodiversity, but it also causes degradation of human health. Recently, nanotechnology has emerged as an answer to these problems having significant role in environmental monitoring, pollution prevention and remediation methods. Nanotechnology has many advantages to improve present environmental technologies and help to create new technologies in comparison to the conventional one. Present article explores the role of different nanoparticles available for environmental remediation purposes and pollution monitoring.

“…Nanofertilizers have perceivable advantages yet nanofertilizers have not been able to make significant inroads into industrial-level production or real farming-world use. Most studies on nanofertilizers development and use show benefits in terms of enhanced nutrient uptake by the plants, increased crop yields, and decreased losses to the environment [ 21 , 70 ]. Yet, several issues hinder the growth of nanofertilizer industry and subsequent use of nanofertilizers in the real world, at least for the time being.…”

“…Nanotechnology deals with the designing of ultra-small entities, having at least one dimension in the range of 1–100 nm. These nano-sized entities or materials represent the transition zone between the individual atom or molecules and their bulk materials, and exhibit extraordinary properties as compared to the bulk counterparts in terms of reactivity and other physico-chemical properties [ 21 ]. The properties of nanoparticles (NPs) are attributed to their high surface area to volume ratio that enhances their chemical reactivity as well as physical responses.…”

Switching to nanonutrients for sustaining agroecosystems and environment: the challenges and benefits in moving up from ionic to particle feeding

The worldwide agricultural enterprise is facing immense pressure to intensify to feed the world’s increasing population while the resources are dwindling. Fertilizers which are deemed as indispensable inputs for food, fodder, and fuel production now also represent the dark side of the intensive food production system. With most crop production systems focused on increasing the quantity of produce, indiscriminate use of fertilizers has created havoc for the environment and damaged the fiber of the biogeosphere. Deteriorated nutritional quality of food and contribution to impaired ecosystem services are the major limiting factors in the further growth of the fertilizer sector. Nanotechnology in agriculture has come up as a better and seemingly sustainable solution to meet production targets as well as maintaining the environmental quality by use of less quantity of raw materials and active ingredients, increased nutrient use-efficiency by plants, and decreased environmental losses of nutrients. However, the use of nanofertilizers has so far been limited largely to controlled environments of laboratories, greenhouses, and institutional research experiments; production and availability on large scale are still lagging yet catching up fast. Despite perceivable advantages, the use of nanofertilizers is many times debated for adoption at a large scale. The scenario is gradually changing, worldwide, towards the use of nanofertilizers, especially macronutrients like nitrogen (e.g. market release of nano-urea to replace conventional urea in South Asia), to arrest environmental degradation and uphold vital ecosystem services which are in critical condition. This review offers a discussion on the purpose with which the nanofertilizers took shape, the benefits which can be achieved, and the challenges which nanofertilizers face for further development and real-world use, substantiated with the significant pieces of scientific evidence available so far.
