\u201cM\u00eb e r\u00ebnd\u00ebsishmja, ekziston nj\u00eb pluhur silic\u00eb, p\u00ebrve\u00e7 pluhurit t\u00eb hekurit t\u00eb bazaltit dhe hekurit nanofaz\u00eb, t\u00eb cil\u00ebt reagojn\u00eb n\u00eb mushk\u00ebri dhe mund t\u00eb shkaktojn\u00eb s\u00ebmundje t\u00eb frym\u00ebmarrjes\u201d.<\/p>\n
K\u00ebrc\u00ebnimi p\u00ebrkeq\u00ebsohet nga madh\u00ebsia e grimcave. Pluhuri marsian \u00ebsht\u00eb m\u00eb i vog\u00ebl se madh\u00ebsia minimale q\u00eb mund t\u00eb nxjerr\u00eb mukoza n\u00eb mushk\u00ebrit\u00eb tona, duke e lejuar at\u00eb t\u00eb udh\u00ebtoj\u00eb m\u00eb thell\u00eb n\u00eb mushk\u00ebri dhe t\u00eb mbetet n\u00eb inde.<\/p>\n
P\u00ebrtej p\u00ebrb\u00ebrjes s\u00eb tij kimike, Marsi paraqet nj\u00eb k\u00ebrc\u00ebnim t\u00eb dyt\u00eb, klim\u00ebn e tij t\u00eb ashp\u00ebr. \u00c7do vit planeti goditet nga stuhit\u00eb rajonale t\u00eb pluhurit dhe \u00e7do disa vjet, k\u00ebto stuhi zgjerohen n\u00eb ngjarje globale, duke mbushur atmosfer\u00ebn me zhavorr n\u00eb aj\u00ebr.<\/p>\n
N\u00eb vitin 2018, nj\u00eb stuhi e till\u00eb \u00e7aktivizoi roverin Opportunity t\u00eb NASA-s duke mbuluar panelet e saj diellore dhe duke bllokuar rrezet e diellit. P\u00ebr astronaut\u00ebt, pasojat shkojn\u00eb p\u00ebrtej humbjes s\u00eb fuqis\u00eb. K\u00ebto stuhi veprojn\u00eb si sisteme masive t\u00eb shp\u00ebrndarjes s\u00eb grimcave toksike. \u201cSilikoza dhe ekspozimi ndaj pluhurit toksik t\u00eb hekurit i ngjajn\u00eb pneumokonioz\u00ebs s\u00eb pun\u00ebtor\u00ebve t\u00eb qymyrit,\u201d shpjegoi Wang.<\/p>\n
Rreziqet e pluhurit planetar nuk jan\u00eb hipotetike. Astronaut\u00ebt e Apollon u p\u00ebrball\u00ebn me rreziqe t\u00eb ngjashme n\u00eb H\u00ebn\u00eb. Pas kthimit n\u00eb mjetin e uljes, shum\u00eb prej tyre pat\u00ebn koll\u00eb t\u00eb vazhdueshme, acarimin e syve dhe madje edhe shikimin e paqart\u00eb pas ekspozimit ndaj pluhurit h\u00ebnor. NASA m\u00eb von\u00eb konfirmoi se rreziqet m\u00eb t\u00eb rrezikshme lidhen me thithjen dhe problemet n\u00eb shikim.<\/p>\n
Megjithat\u00eb, pluhuri marsian shton nj\u00eb nivel tjet\u00ebr toksiciteti. S\u00eb bashku me silic\u00ebn dhe hekurin, regoliti p\u00ebrmban perklorate, gips dhe element\u00eb gjurm\u00eb si arseniku, kadmiumi dhe kromi. Disa nga k\u00ebto substanca njihen si kancerogjene ose shum\u00eb toksike, por efektet e tyre t\u00eb kombinuara n\u00eb kushtet marsiane ende nuk kuptohen mir\u00eb.<\/p>\n
Kur astronaut\u00ebt s\u00ebmuren n\u00eb Tok\u00eb, ndihma \u00ebsht\u00eb vet\u00ebm disa minuta larg.

Nj\u00eb mision i plot\u00eb mund t\u00eb zgjas\u00eb tre vjet, me ekuipazhin q\u00eb kalon nj\u00eb vit ose m\u00eb shum\u00eb n\u00eb gravitet t\u00eb ul\u00ebt, rrezatim t\u00eb lart\u00eb dhe ekspozim t\u00eb vazhduesh\u00ebm ndaj grimcave toksike.<\/p>\n
