Izinhlelo zokulwa nesichotho kanye nemiphumela yazo engaba khona kusomiso zixoxwa kaningi. Kunohlelo olusetshenziswayo lapho kulindeleke ukuthi kube nemvula yesichotho kanti ezinye izindiza ezethulwe nguMbuso zifutha i-iodide yesiliva ukuqeda amafu, ukugwema isichotho nokulimala kwezitshalo. Lokhu sekuvele kubikwe kaningi njengokuthile okulimaza ngempela.
Ngabe uhlelo lokulwa nesichotho luyasithinta isomiso emaxhaphozini?
Uhlelo lwesomiso nesichotho sexhaphozi
I-Gallocanta Lagoon, indawo eyixhaphozi yaseSpain, ibhekene nesomiso esibi ngemva kweminyaka emihlanu ilandelana. Cishe abalimi abangama-300 abavela eGuadalajara, eSoria, eZaragoza naseTeruel Sebebuthene bebonisana ukuthi ngubani obangela ukutsha kwamasimu ngenxa yokuswelakala kwezulu. Lesi sigameko sicutshungulwe ngokwesimo samanye amaxhaphozi nawo abhekana nezinselelo ezifanayo, njengoba kushiwo ku Usuku Lomhlaba Lwezindawo Ezimanzi.
Abalimi babike "izindiza ezisolisayo" ezivela lapho amafu emvula esezokwakheka, avele anyamalale ngaphandle kokuwa. I-Silver iodide iyinhlanganisela yamakhemikhali esiza ukuhlukanisa ukwakheka kwamafu futhi ihlakaze amafu esiphepho. Nakuba abalimi bengezona izazi zesayensi yemvelo noma izazi zezulu, bathi bayawazi amazulu nomhlaba, besebenze ukuphila kwabo konke bencike kukho. Kodwa-ke, i-Geological and Mining Institute of Spain (IGME) ithi, phakathi nophenyo, "Akukabi bikho idatha eqinisekile" ukusungula ubudlelwano phakathi kwabaphehli besichotho nemvula yaseGallocanta, kuchaza umuntu ophethe ucwaningo.
Osekuqinisekisiwe ukuthi imvula yehle kakhulu endaweni yaseGallocanta kunakuyo yonke inhlonhlo kusukela le ngxube isetshenziselwa ukuvimbela isichotho. Lokhu kuhlobene nokukhathazeka okukhulayo mayelana nesimo samanzi ezindaweni ezingamaxhaphozi, okubonisa inkinga ebanzi ekuphathweni kwemithombo yamanzi, njengoba kuxoxiwe ezihlokweni ezithi. Amathebula kaDaimiyeli, indawo nayo ebhekene nesomiso esikhulu.
Uphenyo lwembule idatha ekugxilweni kwe-iodide esiliva emhlabathini okuthi, nakuba ingephezulu kakhulu, idlule imikhawulo evunyelwe umthetho wokusetshenziswa komhlaba. Kusazi sesimo sezulu kanye nomethuli wangezimpelasonto we-El Tiempo en Castilla-La Mancha Media, uJonathan Gómez Cantero, kuyinto “akunakwenzeka neze” kubangela isomiso, futhi icacisa ukuthi indlela ye-silver iodide isetshenziselwa “ukulawula izimo zezulu, hhayi zesimo sezulu.”
Gwema isichotho nge-iodide yesiliva
I-iodide yesiliva iyinhlanganisela yamakhemikhali esebenza njenge into eheha umswakama, okungukuthi, i-hygroscopic. Uma i-iodide eyisiliva ihlangana namafu futhi ikwazi ukusebenza (njengoba ngokuvamile ingasebenzi nhlobo), ibangela ukuba ithonsi liwe ngaphambi kokuba libe yiqhwa. Lokhu kwenzelwa ukuvikela isichotho kanye nomonakalo esingawudala. Kodwa-ke, uchwepheshe uthi i-iodide esiliva ibeka engcupheni yokungcolisa inhlabathi namaxhaphozi, njengoba iyinsimbi okuthi uma ikhulelisa izicubu zezilwane, ingaba yinkinga yangempela kulo lonke uchungechunge lokudla. size sifinyelele nasemizimbeni yethu, njengoba kwenzeka nge-mercury. Lokhu kukhathazeka ngokungcola kuphinde kwabhekwana nendlela ukuguquka kwesimo sezulu okuthinta ngayo imithombo yamanzi angaphansi komhlaba, okuyisihloko esishisayo esingafundwa ku i-hydrogeology, indawo ebalulekile yokuqonda umthelela wezinhlelo zokulwa nesichotho esomiso samaxhaphozi.
Noma kunjalo, kuyaphinda lokho "Akukho ukukhwabanisa kwesimo sezulu", njengoba nje “zingekho izindlela zamakhemikhali noma izindlela zamakhemikhali,” njengoba “izinganekwane zasemadolobheni” zisikisela. Bakholelwa ukuthi kuyadingeka ukunikeza abalimi inkulumo ukuze bayeke ukucabanga ukuthi bazama ukuntshontsha imvula. Okhulumela inkundla yabalimi uthi lokhu kungqubuzana kudalwa wukungabi bikho kwemithetho ngalolu daba. Kunemibono eminingi yobuchwepheshe ngale ndaba. Ezinye izifundo zibonisa ukuthi iodide ayinawo umphumela; abanye bathi ihwamulisa imvula; abanye, ukuthi idlulisela ezindaweni ezingomakhelwane; kanti abanye bathi okuzuzwayo wukuthi lina kakhulu.
Umkhulumeli uphinde abuze ukuthi kungani kufanele akhombise ilayisensi yomsebenzi futhi acacise ukuthi uzoyisebenzisa nini futhi kuphi uma ethenga umuthi wokubulala ukhula. Nokho uhulumeni uyabanika izimvume zokungcolisa umhlabathi abawulimayo. Kuningi okubhaliwe mayelana nemizila ye-chem, futhi iqiniso liwukuthi, kunzima ukwazi ukuthi kuyiqiniso noma cha, uma kubhekwa inhlobonhlobo yemibono kanye nezithakazelo ezifihliwe. Futhi wena, ucabangani ngakho konke lokhu?
