Dr. Luis Antonio Ladino Moreno, specialist in environmental sciences of the UNAM, assured in an interview with EL UNIVERSAL that it is highly unlikely that the Sahara dust I got to the Mexico City, because the clouds dissipate when in contact with the continental territory.
According to the data from satellites that follow the phenomenon, it was determined that the route of the dust will be through the Gulf of Mexico, affecting the Yucatan Peninsula. It is expected to ascend to states in the southern United States such as Texas, Alabama, Florida and Louisiana, where it would finish dissipating and lose all its characteristics.
This phenomenon is common. Depending on the time of year, the winds blow in a specific direction. In the case of summer, in Africa the air blows towards the American continent, so year after year we receive dust from the Sahara, says the expert regarding the origin of the dust cloud.
The particles of the African desert can reach remote distances as long as they have a favorable height, which will also allow greater permanence in the air.
“They (the particles) are lifted to a height of between five and seven kilometers where they can be transported very easily over long distances and their journey is carried out effectively.”

Risks involved in Sahara dust
Solar radiation is a factor that would cause sand from the African desert to drop and allow humans to come in contact with it. Although the use of face masks is recommended, interaction with the sand would hardly cause chronic respiratory disease. “In the worst case it would be an irritation in the mucous ducts or in the throat,” said Ladina Moreno.
“In any case, the Mexican population that could be at greatest risk is the one that lives in the coastal states, since dust will come into contact with the Peninsula,” explained the member of the Atmospheric Science Center.
“The idea is that they avoid breathing these particles and the most efficient way to achieve this will be with the use of mouthguards, in such a way that they become trapped there and do not reach the respiratory system,” he concluded.
