Abstract

With the advent of modern technologies and advanced process, industries had grown by leaps and bounds. Rapid industrialization had in over exploitation of our resources leading to security, simultaneously discharging the pollutant into the environment beyond its assimilative capacity. The impact of such continual exploitation and pollution had lead to the contamination of our water bodies, land and ambient air with toxic compound, which is now threatening the very survival human and other living beings. Maintaining and improving soil, water, and air quality represent some of the most formidable challenges facing global society in the 21st century. Pollutants from such diverse sources as oil and chemical spills,pesticide and fertilizer runoff, abandoned and mining sites, and airborne gaseous an particulate matter from automobile emission and domestic wastes, municipal and industrial solid gets accumulated in the environment. Detecting and treating existing containments and preventing new pollution are amongb the challenges. The aggregate financial burden for improving air, water , and soil quality is truly staggering. In fight of these enormous and complex challenges, it is perhaps ironic that one prospective solution is minute in size but massively powerful in capacity nanotechnology. The remediation of contaminants by use of existing technologies will not be effective enough to meet the futuristic environmental standards and needs innovative advanced technology. Environmental nanotechnology would be a new technology to remediate and treat the contaminants to the acceptable level. Environment scientist are working with nano-scale structure of manipulating matter at the atomic or molecular scale that has cut across such disciplines as chemistry, physics, biology and engineering. Deposit a largely unproven track record in the environmental area, Nanotechnology offers great promise for delivering new and improved environmental technologies. However, proliferation of nanotechnology could also lead to new environmental problems, such as a new classes of toxins or relatedenvironmental hazards. Natural weathering of minerals, such as iron oxides and silicates, and microorganisms, such as bacteria and algae, produce nano-scale collides, which include dispersion of nano sized- particle in media with special properties that can be important in the fate, transport, transformer, and bioavailability of environmentally harmful substances.
