Cyanide ua rau tshuaj lom Cov teebmeem los ntawm inhibiting cytochrome c oxidase, ua rau cellular hypoxia thiab cytotoxic anoxia, thiab tuaj yeem ua rau tuag taus. Thiocyanate concentrations sawv ntau maj as cyanide tau enzymatically hloov mus rau SCN−.
Xav txog qhov no, puas yog hydrogen cyanide tib yam li cyanide?
Hydrogen cyanide yog acidic tsis muaj zog nrog pKib ua 9.2. Nws ib nrab ionizes nyob rau hauv dej tov muab cov cyanide ib, CN−. Ib qho kev daws teeb meem ntawm hydrogen cyanide hauv dej, sawv cev li HCN , yog hu ua hydrocyanic acid. Cov ntsev ntawm cov cyanide anion yog hu ua cyanides.
Tsis tas li ntawd, yuav ua li cas cyanide ua cov pa phem? Qhov chaw ntawm ib puag ncig ua paug yog, ntawm lwm yam mines, metallurgical nroj tsuag thiab tso pa roj los ntawm tsheb. Cyanide ions nkag mus rau hauv ib puag ncig feem ntau los ntawm cov dej khib nyiab. Cov tebchaw no tuaj yeem nkag mus rau ib puag ncig raws li qhov tshwm sim ntawm hluav taws kub ntawm cov chaw ua haujlwm thiab cov tsev thiab cov pa luam yeeb (Daim duab ?
Tsis tas li ntawd, qib ntawm toxicity rau cyanide yog dab tsi?
Thawj tsos mob ntawm Cyanide lom tuaj yeem tshwm sim los ntawm raug rau 20 mus rau 40 ppm ntawm gaseous hydrogen cyanide , thiab tej zaum yuav muaj xws li mob taub hau, tsaug zog, vertigo, qaug zog thiab ceev mem tes, ua pa tob thiab ceev, ib tug kaj-liab xim nyob rau hauv lub ntsej muag, xeev siab thiab ntuav.

Newton thawj txoj cai piav qhia tias cov khoom tseem nyob qhov twg los yog txav mus rau ntawm qhov nrawm nrawm tshwj tsis yog lub zog ua rau lawv. Qhov hnyav (los yog loj) ntawm ib yam khoom, qhov ntau inertia nws muaj. Cov khoom hnyav yog qhov nyuaj txav dua li lub teeb vim tias lawv muaj inertia ntau dua
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
