Waa maxay sababta Shiinuhu u noqday hormuudka soo saaraha adduunka ee Sodium Cyanide

Muddadii u dhaxaysay 2008 ilaa 2015. Shiinuhu waxa uu ku tallaabsaday isbeddel la yaab leh oo dhinaca Sodium cyanide wax soo saarka. Waxa ay ka gudubtay in ay noqoto soodejiye saafi ah oo kiimiko ah oo suntan aadka u saraysa oo noqotay soo saaraha, kaydiyaha, iyo dhoofinta ugu wayn adduunka. Isbeddelkan muhiimka ah ayaa keenaya su'aasha ah: muxuu Shiinuhu u soo baxay inuu yahay dalka hoggaaminaya sodium cyanide wax soo saarka?

Muuqaalka Wax soo saarka Sodium Cyanide Global

Japan waxay ka mid ahayd dadkii hore u soo galay Sodium cyanide domain wax soo saarka. In kasta oo uu Maraykanku awood u leeyahay (shirkadaha sida DuPont ay ku xisaabtamaan 43% wadarta wax soo saarka caalamiga ah) iyo Galbeedka Yurub ee soodhiyamka caalamiga ah cyanide goobta wax soo saarka, shirkadaha Japan sida Kuraray iyo Nippon Soda, iyo kuwo kale, ayaa u suurtageliyay Japan in ay sii wado booska tartanka. Sannadkii 1999. Ilaa 50% wax soo saarka sodium cyanide ee Japan ayaa loo soo mariyey soo saarista methionine, taas oo inta badan loo isticmaalo soo saarista quudinta xoolaha.

Si kastaba ha ahaatee, marka la eego qiyaasta caalamiga ah, codsiga asaasiga ah ee sodium cyanide wuxuu ku jiraa soo saarista dahabka. Tan iyo markii farsamada loo isticmaalo sodium cyanide ee macdanta dahabka ah ay soo baxday 1980-meeyadii, waxaa si ballaaran loo qaatay warshadaha dahabka ee dalal kala duwan. Tusaale ahaan, Koonfur Afrika, 99.5% soo saarista dahabka waxay ku tiirsan tahay habkan; Maraykanka, tiradaasi waa 88.1%, Australia, waa 84.9%. Waqtigan xaadirka ah, 75% ee soodhiyamka cyanide-ka adduunka waxaa isticmaala qaybta macdanta. Warshadaha dahabka ee Waqooyiga Ameerika, Koonfurta Ameerika, Ruushka, Aasiyada Dhexe, Australia, Koonfur Afrika, iyo Shiinaha ayaa ah kuwa ugu badan ee isticmaala kiimikadan.

Kor u kaca qiimaha dahabka ayaa saameyn toos ah ku yeeshay qiimaha sodium cyanide ee loo isticmaalo soo saarista dahabka. Horraantii 2000-meeyadii, qiimaha caalamiga ah ee sodium cyanide wuxuu ahaa agagaarka \(1.600 halkii ton, taasoo kor u kacday ilaa \) 2.800 halkii ton. Kor u kaca qiimahani waxa uu kiciyay balaadhinta wax soo saarka sodium cyanide adduunka oo dhan. Ruushka iyo Peru, tusaale ahaan, waxay si hami leh u dhiseen warshado soo saara cyanide sodium oo leh awood sanadle ah 40.000 tan oo sodium cyanide adag ah. Laakiin wax yar ka dib, waxa hadheeyay kobaca degdega ah ee Shiinaha ee aaggan.

Safarka Soo saarista Sodium Cyanide ee Shiinaha

Shiinuhu waxa uu soo saaray soodhiyamka cyanide waxa uu bilaabmay 1960-meeyadii, iyada oo Shanghai ay ahayd goobtii ugu horaysay ee wax soo saarka. Sannadkii 1980-aadkii, warshadaha kiimikaad ee soo koraya ayaa horseeday koror xooggan oo ku yimid baahida sodium cyanide. Kahor 2008. Shiinuhu wuxuu ku tiirsanaa soo dejinta, isagoo keenaya 10.000 - 30.000 tan oo sodium cyanide ah sanadkii.

Si kastaba ha ahaatee, labada awoodood ee baahida gudaha iyo caalamiga ah ee sii kordheysa, oo ay weheliso kor u kaca qiimaha, gaar ahaan baahida sii kordheysa ee shuruudaha Warshadaha Macdanta Dahabka, waxay kicisay awoodda wax-soo-saarka sodium cyanide ee Shiinaha. Sannadkii 2009. Shiinuhu waxa uu gaadhay guul weyn ka dib markii uu noqday dhoofiye saafi ah oo sodium cyanide ah.

Sannadkii 2011. Soodhiyamka cyanide ee Shiinaha sanadlaha ah wuxuu ku dhawaaday 400.000 tan. Waqtigan xaadirka ah, Shiinuhu wuxuu hayaa horyaalka soo saaraha ugu weyn adduunka ee sodiyam cyanide. Ka sokow daboolida baahiyaha gudaha, waxay dhoofisaa in ka badan 70.000 tan sanadkii. Inta lagu jiro fidinta degdega ah ee warshadaha cyanide sodium, gobolada sida Anhui iyo Hebei ayaa u soo baxay inay yihiin xarumo wax soo saar oo waaweyn.

Warshadaha Macdanta Dahabka

Shiinuhu ma aha oo kaliya soo saaraha hormuudka ah laakiin sidoo kale waa isticmaale weyn oo dahab ah. Kobaca joogtada ah ee wax soo saarka dahabka iyo isticmaalka ayaa horseeday koror la taaban karo oo ku yimid baahida sodium cyanide ee habka macdanta dahabka. Wax soo saarka dahabka ee Shiinaha ayaa muddo dheer ka mid ahaa kuwa ugu sarreeya adduunka. Isticmaalka ballaaran ee habka soo saarista dahabka ee ku salaysan cyanide, kaas oo si heer sare ah ugu hufan soo saarista dahabka macdanta, ayaa si weyn uga qayb qaatay baahida sare ee sodium cyanide. Maaddaama warshadaha macdanta dahabku ay sii wadaan inay ballaariyaan, labadaba marka la eego mashaariicda macdanta cusub iyo ballaarinta kuwa hadda jira, baahida loo qabo sodium cyanide sida reagent soo saarista muhiimka ah ayaa koray si siman.

Qiimaha - waxtarka iyo Faa'iidada Miisaanka

Warshadaha Shiinaha ayaa ka faa'iidaystay dhaqaalahooda baaxadda leh. Waxsoosaarka baaxadda leh, waxay awoodeen inay si weyn u yareeyaan kharashaadka wax-soo-saarka. Qiimahan - wax ku oolnimada ayaa ka dhigay Shiinaha - soo saaray sodium cyanide mid ka tartan badan suuqa caalamiga ah. Waxaa intaa dheer, horumarinta tignoolajiyada wax soo saarka sare ee Shiinaha ayaa sii kordhisay waxtarka wax soo saarka iyo tayada alaabta. Awoodda lagu soo saaro sodium cyanide tayo sare leh oo qiimo jaban ah ayaa soo jiidatay macaamiisha gudaha iyo kuwa caalamiga ah labadaba, taas oo horseedaysa koritaanka warshadaha.

Horumarinta Warshadaha Hoosta

Sodium cyanide waxay u adeegtaa sidii walxo ceeriin ah oo muhiim u ah warshadaha kala duwan ee hoose, oo ay ku jiraan soosaarka dhexdhexaadiyeyaasha kiimikada, daawooyinka, sunta cayayaanka, iyo korantada. Kobaca warshadahan Shiinaha ayaa abuuray baahi xooggan oo loo qabo sodium cyanide. Tusaale ahaan, warshadaha dawooyinka, sodium cyanide waxaa loo isticmaalaa isku-darka dhexdhexaadiyeyaasha dawooyinka qaarkood. Maaddaama warshadaha dawooyinka ee Shiinaha ay sii fidayaan oo ay noqdaan kuwo caalami ah oo tartan badan, baahida loo qabo sodium cyanide oo ah alaabta ceeriin ee aasaasiga ah ayaa sidoo kale kordhay. Sidoo kale, warshadaha elektiroonigga ah, oo si weyn loogu isticmaalo soo saarista qalabka elektiroonigga ah iyo walxaha qurxinta, sodium cyanide ayaa door muhiim ah ka ciyaara hubinta tayada sare ee tayada. Kobaca warshadahan hoose waxa ay siiyeen aasaas adag horumarinta wax soo saarka sodiyamka sodiyam ee Shiinaha.

Ugu Dambeyn

Isku soo wada duuboo, isbadalka Shiinuhu ku sameeyay soo saaraha hormoodka ah ee sodiyam cyanide ee aduunka waa natiijada arimo isbiirsaday. Baahida kor u kacda ee ka imanaysa warshadaha dahabka macdanta, kharashka - istaraatijiyado wax soo saar wax ku ool ah, iyo horumarinta warshadaha hoose ayaa dhamaantood gacan ka geystay koboca cajiibka ah. Si kastaba ha ahaatee, kobacani wuxuu ku yimaadaa mas'uuliyadda hubinta badbaadada adag iyo tallaabooyinka ilaalinta deegaanka. Marka la eego dabeecadda sunta ah ee aadka u sunta ah ee sodium cyanide, maaraynta saxda ah, kaydinta, iyo gaadiidka ayaa ah muhiimada ugu badan. Maaddaama Shiinuhu uu sii wado inuu safka hore kaga jiro wax-soo-saarka sodium cyanide, waa inuu sidoo kale horseedaa hirgelinta hababka ugu wanaagsan ee badbaadada iyo maareynta deegaanka si loo yareeyo khataraha ka iman kara kiimikadaan khatarta ah.
