Kev Tua Hluav Taws Tso Tiv Thaiv Tus Neeg Sawv Cev Txhim Kho Thiab Yam Yuav Tsum Ua Muaj Teeb Meem, Tiv Thaiv Kev Tiv Thaiv
1. Ntawm tag nrho cov pa taws tua hluav taws tua hluav taws, kev pheej hmoo ntawm carbon dioxide yog qhov loj tshaj, feem ntau ntawm kev pheej hmoo ntawm kev tuag. Thaum lub concentration ntawm carbon dioxide ntau tshaj 10%, nws yuav ua rau coma, thiab cov concentration ntawm carbon dioxide tua hluav taws tsim muaj tsawg kawg yog 34%, yog li cov carbon dioxide yog tag submerged. Qhov hluav taws kub tua hluav taws yuav tsum tsis txhob siv rau hauv cov chaw uas neeg feem ntau nyob, thiab yuav tsum tsis txhob siv qee qhov chaw. Tshwj xeeb hauv qab basements thiab lwm qhov chaw, carbon dioxide tsis haum. Carbon dioxide yog hnyav dua pa, uas ua rau kom qhov teeb meem ntawm qhov chaw tawm tom qab txau.
2. Raws li ib txwm muaj, cov hluav taws xob tua hluav taws ntau ntawm heptafluoropropane thiab IG541 tsis siab tshaj qhov NOAEL concentration. Ntawm qhov tsim nyog tsim kev tsim, heptafluoropropane thiab IG541 tsis muaj kev muaj mob thiab muaj kev txaus ntshai.
