Thaum them cov khoom mus los ntawm cov ntaub so ntswg lawv puas cov ntaub so ntswg los ntawm kev tshem cov electrons los ntawm atoms thiab molecules, yog li rhuav tshem lawv lub peev xwm los ua haujlwm. Hluav taws xob yog qhov teeb meem tshaj plaws thaum ntau cov molecules raug rhuav tshem hauv ib puag ncig los ntawm cov concentrated hluav taws xob.
Hauv qhov no, cov hluav taws xob cuam tshuam rau tib neeg lub cev li cas?
Kev puas tsuaj hluav taws xob mus rau txoj hnyuv hauv plab yuav ua rau xeev siab, ntuav ntshav thiab raws plab. Cov hluav taws xob yuav pib rhuav tshem cov cell hauv lub cev uas faib sai. Cov no suav nrog cov ntshav, GI ib puag ncig, cov qog nqaij hlav thiab cov plaub hau, thiab ua phem rau lawv cov DNA thiab RNA ntawm cov hlwb uas muaj sia nyob.
Tom qab ntawd, lo lus nug yog, hluav taws xob tua koj tam sim ntawd li cas? Yog tias 100 tus neeg tau txais tshuaj sai sai ntawm 350 rems ntawm hluav taws xob , txog 3.5 tus neeg tsis txaus siab, tom qab ntawd kwv yees li ib nrab ntawm lawv yuav tuag hauv 60 hnub. 350 rems suav tias yog LD50/60. Nws txhais li cas koj xav.
Qhov thib ob, lub cev dab tsi cuam tshuam los ntawm hluav taws xob?
Cia peb ua lub taub hau-rau-ntiv taw taug kev-los tshuaj xyuas seb cov tshuaj hluav taws xob ntau npaum li cas tuaj yeem ua rau tib neeg lub cev puas tsuaj

- Lub ntsws.
- Lub plawv.
- GI daim ntawv.
- Cov poj niam cev xeeb tub.
- Tawv nqaij.
Lub cev twg cuam tshuam ntau tshaj los ntawm hluav taws xob?
Piv txwv li, txij li cov ntshav tsim cov cell yog ib qho ntawm feem ntau cov hlwb rhiab heev vim lawv qhov kev rov tsim dua tshiab, cov ntshav tsim lub cev yog ib tus ntawm cov feem ntau rhiab heev lub cev rau hluav taws xob . Cov leeg nqaij thiab paj hlwb kuj tsis paub txog hluav taws xob , thiab yog li ntawd, yog li cov leeg thiab lub hlwb.
