Future Trends for Green Environmental Applications of Nanotechnology: A Review

Abstract

Review ArticleProviding a clean and safe environment is one of the great challenges facing humanity. As a result of various human activities over thousands of years in the field of agriculture, industry, housing, burning fuel and elimination of forests and agricultural areas, the environment has been greatly destroyed, and water, air and soil are polluted, and this has resulted in a several risks and problems that It began threatening humanity, perhaps the most important of which is the spread of diseases and epidemics caused by pollution, such as climate change and global warming, which caused major climatic problems that led to storms and floods on the one hand, and drought, desertification and water scarcity on the other hand. It may also lead to bigger and deeper problems if we delay facing this challenge. Green environmental applications such as nanotechnology have great for environmental sanitation (land, water, air) and treatment of pollution resulting from agricultural and industrial activities, accommodation and others. It has a set of low-cost solutions to environmental cleaning problems. Environmental protection is one of the most prominent applied fields that nanotechnology pays great attention to because of the interrelationship between human health and environment in which-it lives. Green technology aims to use less harmful technology to human health and the environment and gradually leads to storage, distribution and use systems that are clean and non-Journal homepage www.ajas.uoanbar.edu.iq

Influence of adding sage leaves on growth performance, nutrient digestibility, and rumen fermentation in Awassi lambs

“…The primary nitrogen source in the rumen is NH3-N, and its decrease from the standard range leads to a decrease in microbial protein production within the normal range 19,29 . Similar results reported that NH3-N concentrations were not affected by increasing levels of sage essential oils 15,16 . Contrary to our results, 3 reported a quadratic increase in NH3-N concentrations with increasing levels of sage oil in an in vitro study using rumen fluid from rams, regarding significant increases in TVFA concentrations in lambs fed low-level (SLP5) and medium-level (SLP10).…”

“…Regarding rumen fermentation variables, with no significant changes in ruminal pH with feeding sage leaves, the values were within the reference range for optimum microbial function 39 . Several in vitro studies reported 2,16 that increasing levels of sage essential oils do not affect ruminal pH. A similar observation was reported by 27, where no significant differences were observed in rumen pH when 0.2 g rosemary leaves /kg live body weight/ day were added to the diet of Barki lambs.…”

“…This is attributed to the effect of phenolic compounds in sage on grampositive bacteria. On the other hand, the effect of flavonoids in sage will stimulate the fermentation activity in the rumen 16 . The results of the current study were similar to those of studies conducted on animals fed on medicinal plants of the family or their participation in the same active compounds.…”

“…Some of these compounds possess antioxidant, anti-inflammatory, antimicrobial, antifungal, anticancer and antibacterial properties 8,10,14 . Numerous studies have evaluated sage leaves and their essential oil as a feed additive, focusing on feed digestibility and methane production using in vitro ruminal fermentation 15,16,17 .…”

Nano Revolution: “Tiny tech, big impact: How nanotechnology is driving SDGs progress"

“…Thus, the potential future directions and trends of nanotechnology [ [195] , [196] , [197] , [198] , [199] , [200] , [201] , [202] , [203] , [204] ] about the 17 Sustainable Development Goals (SDGs) are extensive and varied and, based on all the above, can be summarized in different domains to be further investigated.
