Ahmedabad: Every time a dust storm in Ahmedabad, a local meteorologist and atmospheric scientists have tried to know, how it affects our local environment and the level of pollution including the microbes they carry.
Recently, on April 27, a team of scientists from the physical research laboratory (PRL) and space application center (SAC), ISRO measured a striking increase in dust of 118.5%, which was referred to as an increase in the concentration of PM10 and 44.5% of particles A much smaller called PM2.5.
Both are dangerous for the lungs.
Scientists have measured these values ​​for the first time during the dust using high-tech equipment and satellites.
Dust storm also causes turbulent temperature variations.
It was also reported for the first time in the western region of a temporary disruption of the important (ABL) atmospheric limit on Ahmedabad.
This is an important area of ​​the lower troposphere where the earth’s surface greatly affects the temperature, moisture, and wind through a turbulent air mass transfer.
The study claims that the temperature decreases to around 30 degrees Celsius from about 40 degrees Celsius during the dust event.
The limits are permitted from PM10 and PM2.5 each of 100 and 60 micrograms per cubic meter.
“During the Dust Storm on April 27, the transportation of coarse desert dust besides ABL changes contributed to the high PM10 value which rose to 746.5 micrograms per cubic meter while PM 2.5 levels rose to 273.8 micrograms per cubic meter,” study by Professor Som K Sharma and Shyam Lal from the PRL, senior scientist Abha Chhabra and Prashant Kumar from the Niranjan Kumar sac and the middle range of weather centers.
“The past studies have reported adverse health problems such as early mortality, weakening bronchitis, asthma attacks, other respiratory symptoms, cardiovascular attacks, etc., if humans are exposed to a sudden particle increase,” Prefrint added from this study was published in Research field.
Scientists also see an unstable ABL which then pushes higher dust in the air.
