Tolm on suur r\u00e4ndur. Pole sugugi haruldane, et Aafrika Sahara k\u00f5rbest p\u00e4rit peen tolmukihike ladestub tuhandete kilomeetrite kaugusel asuvatele pargitud autodele.<\/p>\n<\/div>\n

Kuid tolm v\u00f5ib olla surmav. Sahara k\u00f5rbes asuvatel kuivadel \u00e4\u00e4realadel (mida tuntakse Saheli nime all) \u00e4hvardab 300 miljonit inimest surmav haigus, mida nimetatakse meningiidiks.<\/p>\n

See haigus p\u00f5hjustab aju ja seljaaju limaskesta turseid. Neile, keda see haigus ei tapa, v\u00f5ib tekkida kurtus ja ajukahjustus.<\/p>\n

\u201cMeningiidi puhangud tekivad p\u00e4rast vihmata perioodi, kui \u00f5huniiskus on madal ja \u00f5hus on palju tolmu,\u201d selgitas Isabelle Jeanne Nigeris asuvast Centre de Recherche M\u00e9dicale et Sanitaire\u2019ist.<\/p>\n

L\u00e4\u00e4ne-Saharast Kanaari saarte suunas tuule poolt kantud tolm<\/figcaption><\/figure>\n

T\u00e4pne seos ei ole veel teada. \u00dche teooria kohaselt p\u00f5hjustab tuule poolt \u00fclespuhutud tolm, mis on sama peen kui talk, \u00e4rritust inimeste ninas. See h\u00f5lbustab bakterite sattumist vereringesse.<\/p>\n

ESA aitab teadlastel uurida ja ennustada meningiidi puhanguid. Eesm\u00e4rk on saada rohkem teavet surmavate epideemiate kohta, mis sageli j\u00e4rgnevad tolmu saabumisele.<\/p>\n

Meditsiiniteadlased kasutavad satelliidipilte, et j\u00e4lgida Saheli \u00fcle veerevaid tohutuid tolmutorme. Viimase kuiva hooaja jooksul esitas ESA varajase hoiatuss\u00fcsteemi raames igan\u00e4dalasi tolmukaarte. Saheli kaardid p\u00f5hinevad ESA poolt ehitatud Meteosat-7 ilmasatelliidi igap\u00e4evastel piltidel.<\/p>\n

J\u00e4rgmine samm on uurida viimase 10 aasta jooksul tehtud pilte ja otsida seoseid tolmup\u00f6\u00f6riste ja haiguspuhangute vahel.<\/p>","protected":false},"excerpt":{"rendered":"
