TEHRAN-- A group of Iranian scientists has actually managed to discover a way for utilizing nanotechnology to get rid of nitrogen dioxide (NO2), a significant toxic gaseous toxin, from the air.Air contamination is among the most crucial issues in many nations, and to solve it, it is required to go beyond words and take reliable useful steps.In this regard, a group of scientists in the nation have effectively tested using nanotechnology in eliminating essential pollutants.NO2 is related to breathing diseases, particularly asthma, causing breathing symptoms (such as coughing, wheezing, or trouble breathing), health center admissions, and check outs to emergency rooms.The main source of nitrogen dioxide resulting from human activities is the combustion of nonrenewable fuel sources (coal, gas, and oil) specifically fuel used in cars.It is likewise produced by making nitric acid, welding and using explosives, refining fuel and metals, industrial production, and food manufacturing.In order to manage and decrease the emission of nitrogen oxides, various kinds of products called catalysts are used.
In this regard, scientists have actually been paying more attention to nano-catalyst materials.The 2022 update of the World Health Organizations air quality database presents, for the first time, ground measurements of annual mean concentrations of nitrogen dioxide, a common city pollutant, and precursor of particle matter and ozone.It also includes measurements of PM10 or PM2.5, both stem primarily from human activities associated with fossil fuel combustion.Sulfur dioxide is likewise a colorless gas or liquid with a strong, choking odor.
It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) which contain sulfur.The harmful air is putting 10s of millions of people at threat-- not just in the capital but across the country.Effects of air pollution on mental health are stress and anxiety, productivity, concentration and focus, psychological exhaustion and fatigue, dementia and other mental illness, mood changes and irritability, and consequences of air pollution on your physical health.Particulate matter is capable of penetrating deep into the lungs and going into the blood stream, causing cardiovascular, cerebrovascular (stroke), and respiratory impacts.
There is emerging evidence that particulate matter impacts other organs and triggers other diseases as well.The nano industry is among the technological fields that has actually processed development and development in Iran, so that, the intro of these quality items to the world is a necessity.Iran Nanotechnology Innovation Council has actually been executing strategies to reinforce the nano sector over the past few years.Some 270 business are active in the nanotechnology field and it is predicted that their revenue will rise to 80 trillion rials (nearly $310 million), the previous Vice President for Science and Technology, Sourena Sattari, said.On November 28, 2022, President Ebrahim Raisi declared to implement the National Document for the Development of Nano Science and Technology .
Consisting of 7 posts, the ten-year document aims to train personnels and provide facilities for the development and commercialization of technology.
Priority enterprise zones are water and environment, energy, farming, health, and construction.MG
