Although the amount of dust entering Mexico is insufficient to pose a high risk, it could lead to involvement in people with chronic respiratory diseases and even influence the climate.
The Sahara is the largest desert in the world, its territory spreads across 11 countries in Africa and its surface is comparable to that of China or the United States. Today, a cloud of dust from that place is advancing over the Yucatan Peninsula and while it does not pose a greater risk to the population, authorities recommend that they be attentive to indications to avoid any involvement.
The Atlantic Oceanographic and Meteorological Laboratory holds that this dust “is a very dry, dusty air mass that forms over the Sahara Desert in late spring, during the summer and early autumn, and usually moves towards the North Atlantic Ocean every 3-5 days.”
Meanwhile, the National Center for Disaster Prevention (Cepapred) adds that this cloud of dust “can cover an area equivalent to that of the United States and extend vertically between 500 and 6 thousand meters in height.” We recommend: Saharan Powder will reach only the Yucatan Peninsula; rule out high risk So you can see live the advance of the Dust from the Sahara that will come to Mexico
Is the dust of the Sahara dangerous?
Although concentrations of African desert dust arriving in Mexico do not pose a high risk to the population, according to the Cenapred, these clouds can cause impact on people who aspire to it. In this regard, the World Health Organization (WHO) explains that “particles larger than 10 micrometers cannot be breathed and damage only external organs (mainly cause skin and eye irritation, conjunctivitis and increased susceptibility to eye infections).
“Particles that can be inhaled, those smaller than 10 micrometers in size, are usually trapped in the nose, mouth and upper respiratory tract and can be associated with respiratory disorders such as asthma, tracheitis, pneumonia, allergic rhinitis and silicosis. However, smaller particles can penetrate into the lower part of the respiratory tract and enter the bloodstream, from where they can affect all internal organs and cause cardiovascular disorders,” the institution notes. Sahara Powder Recommendations to avoid impacts Before the cloud of dust advancing over the Yucatan Peninsula, cenapred recommends:
– Avoid exposure to high dust concentrations –
Take shelter during these events -Close all air inlets to the rooms during storms -If it is necessary to be outdoors, wear lenses and mouth covers or handkerchief In addition, the Cenapred states that people with chronic respiratory diseases, older adults, pregnant women and children should wear respiratory protectors such as masks or a wet cloth scarf to cover nose and mouth. If you have a sensation of foreign bodies in your eyes, wash with plenty of water.
It is recommended to moisten the floor of your home before sweeping to avoid resuspension of dust that may accumulate on the floor.
Saharan dust can not only cause health conditions for people, but can also influence a region’s climate, cenapred explains. “When encountered with a tropical cyclone, the dust of the Sahara suppresses the rising air currents of the cyclone, and the horizontal winds that carry it significantly change the direction of the wind in the environment. Studies suggest that it may reduce cloud formation, so there would be less chance of tropical cyclones developing in the Atlantic,” he says. https://www.milenio.com/ciencia-y-salud/polvo-del-sahara-que-es-y-en-que-me-afecta
