TEHRAN (FNA)- Iranian scientists at Imam Khomeini University of Qazvin have made a system to reduce the dust and air pollution, using ultrasonic frequency.
The new system turns water into very tiny drops by using ultrasonic frequency and then spreads them into the environment after being combined with the air.
The cool moist increases humidity in the environment without wetting the objects and given its heaviness takes dust, air pollution and bad smell down the earth.
The system can be used in food and agricultural industries and is being produced at semi-industrial level.
Air pollution shortens human lives by more than a year, according to a new study from a team of leading environmental engineers and public health researchers. Better air quality could lead to a significant extension of lifespans around the world.
This is the first time that data on air pollution and lifespan has been studied together in order to examine the global variations in how they affect overall life expectancy.
The researchers looked at outdoor air pollution from particulate matter (PM) smaller than 2.5 microns. These fine particles can enter deep into the lungs, and breathing PM2.5 is associated with increased risk of heart attacks, strokes, respiratory diseases and cancer. PM2.5 pollution comes from power plants, cars and trucks, fires, agriculture and industrial emissions.
