Pfupisa nyaya yacho:  Magasi anodzvinyirira anoshandiswa kutumira varwere kunorara mukati mokuvhiyiwa ari kuunganidzwa mumhepo yakapoteredza Pasi apo ari kubetsera kuchinjwa kwemamiriro okunze. Masayendisiti anotaura kuti akawana magasi anoshandiswa mumushonga wokuuraya pfungwa ari kure zvikuru seAntarctica uye kuwanda kwawo kwave kuchikwira munyika yose mumakore gumi apfuura. Magasi aya - desflurane, isoflurane, uye sevoflurane - magasi ane simba anokonzera kuti nyika itonhore, ane simba rinopetwa ka2 500 pane carbon dioxide. Anesthetic inoshandiswa kutumira varwere kuti varare panguva yokuvhiyiwa (pamusoro) asi inogonawo kuva iri kudziya nyika. Masayendisiti anoongorora mamiriro okunze ave achiongorora magasi acho anoti kunyange zvazvo ari mashoma mumhepo, ari kuwedzera kukanganisa mamiriro okunze. Dr. Martin Vollmer, uyo akatungamirira fundo yacho paSwiss Federal Laboratories for Material Science and Technology muDubendorf, Switzerland, akati magasi anodzvinyirira aikwanisa kuchengeta simba rakawanda zvikuru rinobva kuzuva kupfuura carbon dioxide. Nyika inofanira kuzvigadzirira kuti ikurumidze kuchinja kwemamiriro okunze, vanamazvikokota vezvesayenzi vanonyevera kudaro. Vanzveri vakawana ufakazi hunokarakadza kuti mwero umo tembiricha iri kukwira muchikamu chenyika chokumusoro ungava 0.25°C pagumi ramakore panosvika 2020 - mwero usina kuonwa kweanodokusvika makore 1.000. Ongororo yacho, yakavakirwa pamubatanidzwa wemashoko anobva kumamodeli emamiriro okunze anopfuura makumi maviri anobva munyika yose, yakatarisa mwero wokuchinja mumakore 40 akareba. Kwemakore 900 zana remakore rechi20 risati rasvika, kupisa kwemamiriro okunze kwamakore 40 kwaiwanzoratidza mwero weavhareji wakakwirira zvikuru kupfuura 0.1°C pagumi remakore, tsvakurudzo yacho yakawana kudaro. Asi panosvika gore ra2020 mwero wacho waitarisirwa kunge wakwira kusvika paavhareji ye0.25°C pagumi remakore, kupa kana kubvisa 0.05°C. Zviratidziro zvakasiyana-siyana zvemhepo ichabuda munguva yemberi zvakaratidza kuti kunyange pamwero wakaderera wekugadzirwa kwemagasi anopisa, kuchinja kwemamiriro okunze kwakawedzera kukurumidza mumakore 40 anotevera. Akati: 'Pachikero chechikirogiramu-pa-kirogiramu, ine simba zvikuru kwazvo. 'Mishonga yemazuva ano inonyudza inonzi halogenated in undergoes little metabolism during clinical...
Magasi anoshandiswa muzvinodhaka ari kuunganidzwa mumhepo yepasi. Magasi - desflurane, isoflurane uye sevoflurane - ane mhedzisiro yegreenhouse ine simba rakapetwa ka2.500 kupfuura carbon dioxide, vanodaro masayendisiti. Kudzidza kutsva kunoratidza kuti uwandu hwazvo hwakaderera asi huri kuwedzera. Masayendisiti anokurudzira zvipatara kuti zvitsvake dzimwe nzira dzinoshamwaridzana nemhoteredzo.
