Dust from the Sahara does not pose serious risks to the population: UNAM


The arrival of Sahara dust in the national territory it has generated concern among the population; however, experts from the National Autonomous University of Mexico (UNAM) They assured that there are no serious risks and even stated that their arrival will bring some benefits.

Luis Ladino Moreno, from the Atmospheric Sciences Center (CCA), pointed out that the dust mass contains PM2.5 and PM10 particles (respirable material in suspension in the atmosphere of a size between 2.5 to 10 microns), so the danger of breathing the dust cloud is minimal, since it is located between five and seven kilometers above sea level.

Dust could impact our health if it were to drop, since the particles are harmful only when aspirated: “Air quality can be affected in the Yucatan Peninsula; the call is to take certain care such as wearing face masks and protecting your eyes, “he recommended.

During a virtual conference, Ladino Moreno and Alejandro Aguilar Sierra, from the National Laboratory for Earth Observation (LANOT) of the UNAM Geography Institute, detailed that it was through the GOES-16 meteorological satellite of the National Aeronautics Administration and the Space (POT), by which they followed the event to obtain key information.

Through a statement from the Maximum House of Studies, the specialist specified that this powder contains minerals that fertilize the ocean and the land, which will benefit the soils of Yucatan, Quintana Roo and Campeche. Furthermore, as it is a highly arid and dry compound, it has the ability to inhibit the formation of hurricanes and clouds in our territory.

Despite the fact that this phenomenon happens year after year, the magnitude of the dust cloud increased by 800%, a circumstance that has not been seen for 50 years.

Other particularities that differentiate the presence of dust from that of past years, which is usually present during the summer, is that the mass will remain for approximately four days in the area. Then it will continue its way through the Gulf of Mexico and could reach Texas, Louisiana, Alabama and Florida, in the United States.

For his part, the undersecretary of Prevention and Health Promotion, Hugo López-Gatell, stated during the evening press conference that the dust cloud could intensify the ailments of those who suffer chronic respiratory diseases, such as bronchitis, emphysema, and asthma, so he advised susceptible people to stay safe at home.
