Did you miss it? Dust is coming to Poland from the Sahara
Forecasters emphasize that winter has not yet said its last word, and frosts may return soon. However, before this happens, another dangerous phenomenon will come to Poland. Scientists warn that a huge cloud of dust is approaching Europe from the Sahara. According to experts, Saharan dust will first reach France, Greece and Bulgaria, and then penetrate deeper into the continent.
Data collected from the Copernicus program indicate that on Wednesday, March 4, the dust cloud from the Sahara may also reach the Vistula River. The wind will carry it to the northern part of the country and then to the entire length of Poland. However, this is not all, according to polskieradio24, the ash cloud in our country may combine with another one that will be brought over Poland from the Czech Republic and Slovakia. The most dust may be noticeable in the Lubusz region, Greater Poland and Podlasie. The cloud from the Sahara will also reach Lower Silesia, Silesia, the Opole region, Podkarpacie and Lesser Poland.
What is Sahara dust and is it dangerous to health?
Sahara dust is a natural atmospheric phenomenon that transports small particles of sand and minerals from the Sahara Desert over long distances. It is one of the world’s largest natural transports of aerosols, affecting climate, ecosystems and air quality on several continents. Saharan dust consists mainly of minerals such as quartz, kaolinite, illite, chlorite and other clay minerals. It also contains trace amounts of metals such as iron, magnesium and calcium. Depending on the Sahara region it comes from, its composition may vary slightly. These particles are usually dry, but when in contact with moist air they can serve as condensation nuclei for clouds, influencing the weather.
carries the risk of “blood rain”. This is a specific phenomenon when sand particles present in the atmosphere are pulled to the ground. Then this dust settles on .
Most Saharan dust episodes in Europe do not pose a serious health risk to the general population. However, due to the presence of fine particulate matter (PM10 and PM2.5), it can affect air quality and pose a problem for certain groups of people:
- People with respiratory diseases: Asthmatics, people with chronic obstructive pulmonary disease (COPD) and other respiratory diseases may experience increased symptoms such as cough, shortness of breath or wheezing.
- People with heart disease: Fine particles can affect the circulatory system, leading to exacerbation of symptoms in people with coronary artery disease or heart failure.
- Children and the elderly: Their respiratory and immune systems are more sensitive to air pollution.
- Allergy sufferers: Although dust itself is not an allergen, it can transport plant pollen, fungal spores or other allergens, which may worsen allergy symptoms.
