Qhov sib txawv tseem ceeb ntawm bioaccumulation thiab biomagnification yog bioaccumulation yog hais txog kev tsim cov tshuaj lom neeg hauv lub cev ntawm cov kab mob uas muaj sia nyob thaum biomagnification yog qhov nce ntxiv ntawm cov tshuaj lom thaum mus raws cov khoom noj khoom haus..
Cov khoom noj khoom haus yog qhov tseem ceeb ntawm kev sib cuam tshuam ntawm cov kab mob hauv cov ecosystems. Nws pib nrog thawj tus tsim khoom, feem ntau yog cov nroj tsuag uas yog photoautotroph. Nroj tsuag tsim zaub mov rau lawv tus kheej siv hnub ci thiab inorganic carbon qhov chaw. Herbivores nyob qib thib ob ntawm cov khoom noj khoom haus Qib Tom ntej no feem ntau nyob ntawm omnivores thiab carnivores. Cov khoom noj khoom haus zoo piav qhia qhov kev cia siab ntawm txhua qib rau zaub mov. Ib yam li ntawd, cov khoom noj uas tsim nyob rau hauv qab yog dhau mus rau theem siab. Nrog rau cov khoom noj, txawm tias cov khoom nyob rau hauv qis trophic qib kuj tuaj yeem raug xa mus rau qib siab nrog rau cov as-ham. Bioaccumulation thiab biomagnification yog ob qhov tshwm sim uas cuam tshuam txog kev dhau ntawm cov khoom phom sij raws cov khoom noj khoom haus mus rau qib siab.
Dab tsi yog Bioaccumulation?
Bioaccumulation yog qhov sib xyaw ntawm cov tshuaj lom hauv cov kab mob muaj sia. Nws tshwm sim dhau lub sijhawm. Cov tshuaj no tuaj yeem yog cov hlau hnyav, tshuaj tua kab, lossis cov tshuaj organic. Lawv nkag mus rau hauv cov txheej txheem nyob ntawm dej los yog zaub mov. Bioaccumulation tshwm sim los ntawm cov khoom noj khoom haus. Lub tsub zuj zuj ntawm cov tshuaj lom nyob rau hauv qis trophic qib yog tsawg dua piv rau cov qib siab trophic. Feem ntau, lub cev muaj cov txheej txheem los tshem tawm tag nrho cov khoom uas tsis xav tau thiab tshuaj lom los ntawm lub cev. Yog li ntawd, bioaccumulation tshwm sim thaum lub accumulating tus nqi ntau dua li tus nqi tshem tawm. Yog li ntawd, yog hais tias lub neej ntawm cov khoom yog siab dua, qhov cuam tshuam ntawm nws kuj tau siab dua.
Daim duab 01: Bioaccumululation
Feem ntau, lub raum yog lub luag haujlwm tshem tawm feem ntau ntawm cov khoom tsis xav tau ntawm lub cev. Ntshav nqa lawv mus rau hauv ob lub raum thiab tom qab ntawd cov zis tshwm sim los ntawm kev pom thiab xaiv reabsorption. Txhawm rau tshem tawm cov co toxins nrog cov zis, lawv yuav tsum yog dej soluble. Tab sis, bioaccumulative tshuaj feem ntau yog cov rog soluble thiab braking lawv mus rau hauv me me molecules yog tsis tau. Yog li ntawd, lawv nyiam nyob hauv lub cev.
Biomagnification yog dab tsi?
Biomagnification yog qhov nce ntxiv ntawm cov tshuaj lom neeg lub sijhawm thaum mus rau theem qis mus rau qib siab dua hauv cov khoom noj khoom haus. Cov pa phem yuav tsum tau nyob ntev thiaj li ua rau biomagnification. Tsis tas li ntawd, nws yuav tsum tau txawb, kom nws yooj yim nkag mus rau hauv cov kab mob lom los ntawm kev noj zaub mov lossis dej. Yog tias nws tsis yog mobile, nws yuav nyob hauv ib lub cev thiab yuav tsis dhau mus rau qib tom ntej trophic. Ntxiv mus, yog tias lawv soluble hauv cov rog, lawv zoo li nyob hauv lub cev ntawm cov kab mob mus ntev.
Daim duab 02: Biomagnification
Tsis tas li ntawd, txhawm rau txhawm rau biomagnification tshwm sim, cov pa phem yuav tsum ua kom muaj roj ntsha. Piv txwv li, DDT yog chlorinated hydrocarbon uas tuaj yeem biomagnified. Nws yog tshuaj lom rau kab thiab muaj ib nrab-lub neej ntawm 15 xyoo. Cov hlau hnyav xws li mercury, lead, cadmium, zinc kuj yog tshuaj lom thiab tuaj yeem ua biomagnified.
Dab tsi yog Qhov Zoo Sib Txawv Ntawm Bioaccumulation thiab Biomagnification?
- Ob qho tib si bioaccumululation thiab biomagnifications muaj feem xyuam rau cov tshuaj lom.
- Nyob rau hauv ob qho tib si, cov tshuaj yog rog soluble.
- Kuj, cov tshuaj no yog mobile.
- Tsis tas li ntawd, cov tshuaj no tsis tuaj yeem tawg ua cov molecules me.
- Ntxiv mus, cov tshuaj no tau nyob ntev.
Qhov txawv ntawm Bioaccumululation thiab Biomagnification yog dab tsi?
Bioaccumulation yog qhov nce ntxiv ntawm cov khoom hauv ib lub cev thaum biomagnification nce qib thaum koj nce mus rau hauv cov khoom noj. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm bioaccumululation thiab biomagnification. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm bioaccumululation thiab biomagnification yog tias bioaccumulation tshwm sim nyob rau hauv ib qho chaw sov thaum biomagnification tshwm sim ntawm qib trophic.
Cov ntaub ntawv hauv qab no-daim duab qhia txog qhov sib txawv ntawm bioaccumululation thiab biomagnification.
Summary – Bioaccumululation vs Biomagnification
Bioactive, fat-soluble, nyob ntev cov tshuaj lom neeg muaj nyob hauv cov khoom noj uas muaj nyob hauv cov khoom noj. Tsis tas li ntawd, qhov concentration ntawm cov tshuaj lom neeg nce ntxiv hauv cov kab mob. Bioaccumulation thiab biomagnifications yog ob txheej txheem ntsig txog qhov no. Bioaccumulation yog hais txog qhov nce ntawm qhov concentration ntawm cov tshuaj lom hauv lub cev thaum biomagnification yog hais txog qhov nce ntawm cov concentration ntawm cov tshuaj lom thaum mus los ntawm qib qis mus rau qib siab hauv cov khoom noj. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm bioaccumululation thiab biomagnification.
